SUNOCO Sunice SL-220T is a synthetic polyol ester (POE) refrigeration oil with a kinematic viscosity of 216.0 cSt at 40 °C, which places it inside the ISO VG 220 band. It belongs to Japan Sun Oil's Sunice SL series, the synthetic line that was marketed as the SUNISO SL series until the brand name of the synthetic products was changed in 2017. The series is designed for compressors charged with HFC and HFO refrigerants, and Japan Sun Oil states that it is miscible and compatible with R-134a, R404A, R407C, R410A and R507.
We supply this grade in two forms. The first is the original SUNOCO product from Japan Sun Oil Company. The second is the equivalent POE grade we manufacture ourselves at our own blending plant in Foshan, China — our ester range covers 22 to 220 cSt at 40 °C, and the 220 cSt grade is our QSL-220H. Both ship from Guangzhou. There is no fixed minimum order — it is confirmed per order, because a single can and a full container load are both workable and the figure moves with the pack size, the quantity and the destination. Delivery is on any Incoterms 2020 term — EXW, FOB, CFR, CIF, DDP and every other rule — and payment is on any commonly used method, including T/T, L/C and PayPal — send the compressor model, the refrigerant and the system's evaporating temperature and we will quote both, so you can compare on landed cost.
QISHANR is a refrigeration oil manufacturer and wholesale supplier, and this grade is supplied in bulk to distributors, HVACR service companies and compressor OEMs worldwide.
SUNOCO Sunice SL-220T is supplied on published terms: the viscosity class, the price terms, the payment terms and the documents are the same for every buyer, and they can be quoted without a site visit. The minimum order is deliberately left open, because it is judged case by case: the grade, the quantity, the pack size, the shipping terms and the container load all move it, so a single can and a full container load are both workable and neither is treated as the normal case. Send us the quantity, the destination port and whether your own brand goes on the container, and those three turn the table below into a firm quotation. Documents and lead time work the same way on every order: the technical data sheet and safety data sheet come with the quotation, and the certificate of analysis for the delivered batch comes with the shipment. This grade is supplied wholesale and in bulk — to distributors, HVACR service companies, compressor OEMs and private-label buyers — as well as in single packs and sample quantities.
| Item | Terms for Sunice SL-220T |
|---|---|
| Minimum order quantity | Not a fixed figure — confirmed per order, because it is judged case by case: the grade, the pack size, the quantity, the shipping terms and the container load all move it, so a single can and a full container load are both workable |
| Payment terms | Any commonly used payment method — T/T, L/C, PayPal and every other option — confirmed with the order |
| Price terms | Any Incoterms 2020 term — EXW, FOB, CFR, CIF, DDP and every other rule — quoted against your destination port |
| Supply ability | 1,000 pieces per year |
| Origin | The original SUNOCO product, or an equivalent manufactured at our own plant in Foshan, China |
| Supply options | The original SUNOCO Sunice SL-220T from Japan Sun Oil Company, or the equivalent 220 cSt POE grade we manufacture at our blending plant in Foshan, China (our QSL-220H — 220 cSt at 40 °C, category ISO VG 220) |
| Who buys this grade | Distributors and resellers who stock refrigeration oil, HVACR and refrigeration service companies, compressor OEMs filling new equipment, and buyers who need private-label or own-brand packing. Wholesale and bulk orders are the norm; trial and sample quantities are also supplied. |
| Grade confirmation | Send the compressor model, the refrigerant and the evaporating temperature. The SL series covers 10 to 320 cSt at 40 °C, and 220 cSt is the higher-viscosity end of that range, so we confirm that SL-220T is the right viscosity for your system before quoting |
| Viscosity class | 216.0 cSt at 40 °C, which falls inside the ISO VG 220 band (198–242 cSt) defined by ISO 3448 |
| Pack size | Confirmed at quotation. Custom pack formats are available as a quotation item. |
| Documents issued with the order | Technical data sheet, safety data sheet, and a certificate of analysis for the delivered batch |
| Handling and storage | Store sealed, away from direct sunlight, and keep the container closed between top-ups — polyol ester oils absorb moisture from the air, and moisture is what shortens their service life. Do not decant into an unlined steel drum. |
Supply ability is stated for this grade rather than for the plant as a whole. It is not the annual capacity of the blending plant.
The line between one viscosity class and the next is drawn by the compressor duty and the refrigerant, not by the drum size. Send the model and the refrigerant and we will confirm which class your system takes.
A lubricant order is rarely only a lubricant order. The buyer is usually solving a grade question, an import documentation question, a freight question and a packaging question at the same time — often across more than one product family. Those are the parts of the job we take on, and they are handled by the same team that quotes the oil rather than passed to a third party.
We are a manufacturer rather than a reseller, which is what makes that possible. The blending plant in Foshan, Guangdong runs at 6,000 tonnes a year and has been producing lubricants for more than ten years, so the answer to most of the questions below comes out of our own production and our own paperwork. The enquiries that reach us on this grade are consistent: the buyer has an oil in the system, a data sheet in hand, and needs to know whether the two match.
| What you are dealing with | What we do about it |
|---|---|
| You cannot tell whether the system takes 220 cSt or the 170 cSt grade next to it | Send the compressor model, the refrigerant and the operating temperatures. The Sunice SL series is the same oil type at a range of viscosities and the higher-viscosity grades are separated by the compressor duty and the refrigerant, so the answer comes from the data sheet rather than from the can. We confirm the grade in writing before you order, so it can be checked against the specification. |
| You are converting a CFC/HCFC system to an HFC refrigerant | HFC and HFO refrigerants are not miscible with mineral oil, so a conversion changes the oil as well as the gas. The Sunice SL series is the polyol ester line Japan Sun Oil designed for HFC/HFO duty, and its GS mineral line is the mineral counterpart. We will tell you what the changeover involves on the documentation side, including the moisture limit a polyol ester charge has to meet. |
| You need the original SUNOCO product and the paperwork to match it | We quote the original Sunice SL-220T with its manufacturer documentation, or our own equivalent with our own batch certificate of analysis — and we say plainly which one is which, so the choice is yours and not buried in the invoice. |
| You are buying alongside other oils and want them on one order | Refrigeration oils are the core of our business, not the whole plant. The same lines produce air compressor oils, vacuum pump oils and general industrial lubricants, and a mixed enquiry can be quoted, packed and shipped together rather than split across suppliers. |
| You need documentation for customs or for a tender | CE, CO, MSDS and transport certification are issued as standard documents with an export order. Tell us at the enquiry stage which certificate the destination requires and we compile the file with the quotation rather than after the shipment. |
The point of this list is that the questions are answered before the order rather than after it. If you are unsure which of them applies to you, describe the system and we will tell you what we need.
Grade confirmation comes before pricing, because the Sunice SL range is the same oil type at a range of viscosities and a wrong class is the mistake that costs a compressor. The sequence is the same whether you are buying one can or a full container:
If you already know the grade and only need a price, send the quantity and the destination port and we will quote directly.
The values below are those Japan Sun Oil Company publishes for Sunice SL-220T in its Sunice product portfolio. The 40 °C viscosity of 216.0 cSt is the figure that sets the class: it falls inside the ISO VG 220 band of 198–242 cSt defined by ISO 3448, which is what allows this grade to be compared with other 220 cSt refrigeration oils. The pour point of −27.5 °C limits cold-end duty, and the flash point of 286 °C by open cup (COC) sets the hot end.
| Property | Typical Value | Source |
|---|---|---|
| Oil type | Synthetic polyol ester (POE) | Japan Sun Oil — Sunice product portfolio |
| ISO viscosity grade | ISO VG 220 (ISO 3448) | Derived — 216.0 cSt falls inside the 198–242 cSt band |
| Kinematic viscosity at 40 °C | 216.0 cSt | Japan Sun Oil — Sunice product portfolio |
| Kinematic viscosity at 100 °C | 19.0 cSt | Japan Sun Oil — Sunice product portfolio |
| Density at 15 °C | 0.976 g/cm³ | Japan Sun Oil — Sunice product portfolio |

Values as published by Japan Sun Oil Company, Ltd. in its Sunice product portfolio. The ISO VG 220 class is not printed by the manufacturer as a grade number; it is derived here from the published viscosity at 40 °C and the ISO 3448 bands, and it is stated so that the value can be compared with other oils sold at the same class. Where a figure is not published we have left it out rather than estimate it. Send us the system details if you need a property we do not list.
A viscosity class is a band, not a single number, and the two figures below are the ones that decide whether a 220 cSt polyol ester suits a given circuit. Both come from the published values above rather than from our own measurement.
| Parameter | Value for Sunice SL-220T | What it controls |
|---|---|---|
| Kinematic viscosity at 40 °C | 216.0 cSt — inside the ISO VG 220 band of 198–242 cSt | The film thickness in the bearings and the load the oil places on the compressor. This is the figure a replacement has to match. |
| Viscosity at 100 °C | 19.0 cSt | How much the film thins at operating temperature. The higher this figure, the smaller the drop from the 40 °C value. |
| Pour point | −27.5 °C | The cold end of the working window. Below this the oil stops flowing, so a system running colder than this needs a lower-pour-point grade. |
| Flash point (COC) | 286 °C | The hot end of the working window and a rough measure of how the oil behaves at the discharge valve. |
Do not step to a heavier class to solve a wear problem without checking the compressor duty with us first. Raising the viscosity raises the load on the machine, and on a system that was specified for a lighter oil that is the wrong direction of travel.
Japan Sun Oil's Sunice range has two mineral lines and one synthetic line. The SL series is the synthetic polyol ester line, and its grades share the same oil type at different viscosities. The table below places SL-220T against the grades next to it, using the manufacturer's published 40 °C viscosity.
| Grade | Oil type | Viscosity at 40 °C | ISO VG class | Where it is used |
|---|---|---|---|---|
| Sunice SL-100S | POE (synthetic) | 98.1 cSt | ISO VG 100 | The lower-viscosity synthetic grade in the same series |
| Sunice SL-120T | POE (synthetic) | 115.8 cSt | Outside any ISO VG band | Between the 100 cSt and 170 cSt grades |
| Sunice SL-170T | POE (synthetic) | 161.0 cSt | ISO VG 150 | The grade below this one |
| Sunice SL-220T (this product) | POE (synthetic) | 216.0 cSt | ISO VG 220 | Higher-viscosity synthetic grade for heavier-duty refrigeration and air-conditioning plant |
| Sunice SL-320T | POE (synthetic) | 310.0 cSt | ISO VG 320 | The highest-viscosity grade in the synthetic SL line |
Figures from the Japan Sun Oil Sunice product portfolio. Grades that sit between two ISO VG bands are shown without a class number, because the standard defines no grade at that viscosity — SL-120T at 115.8 cSt is one example, falling between the VG 100 and VG 150 bands.
If your compressor is already in service, the oil you are replacing is the only reference point you have. These are the grades we can verify at 220 cSt from published data, with our own equivalent listed first:
| Brand | Grade | Viscosity at 40 °C | Note |
|---|---|---|---|
| Qishanr | POE refrigeration oil | 220 cSt, our QSL-220H | Our own equivalent, blended at our plant in Foshan, China |
| SUNOCO | Sunice SL-220T | 216.0 cSt | The grade this page covers |
| SUNOCO | Sunice SL-320T | 310.0 cSt | Not a replacement — the next heavier class in the same series |
| SUNOCO | Sunice SL-170T | 161.0 cSt | Not a replacement — the next lighter class in the same series |
This table is deliberately short. The 220 cSt polyol ester class is less crowded than 32 cSt or 68 cSt, and we would rather leave a row out than print a viscosity we cannot source. If the oil you are replacing is not listed, send its data sheet and we will check the viscosity and base oil type before quoting. A cross-reference is the starting point for a specification review, not the answer: confirm the final choice against the compressor manufacturer's approved oil list for your model and refrigerant.
SUNOCO Sunice SL-220T is a synthetic polyol ester (POE) with a viscosity of 216.0 cSt at 40 °C, and the base oil type is the part that decides whether the charge works at all. HFC and HFO refrigerants are not miscible with mineral oil, so a mineral charge in an R-134a or R407C circuit does not travel with the refrigerant: oil collects in the evaporator and the compressor sump runs dry. Polyol ester is miscible with those refrigerants, so the oil circulates through the circuit and returns to the sump. Japan Sun Oil designed the Sunice SL series specifically for HFC/HFO duty and names R-134a, R404A, R407C, R410A and R507 as miscible and compatible.
Naming: the Sunice SL series was marketed as the SUNISO SL series until the brand name of Japan Sun Oil's synthetic products was changed in 2017. Older plant documentation may still carry the SUNISO name for the same oil.
The viscosity class is chosen from the compressor duty, not from the drum size. A heavier oil forms a thicker film in the bearings and carries more load, which is what a large centrifugal or screw compressor running HFC refrigerant needs; the same oil in a machine specified for a lighter class raises the internal load and the discharge temperature. Japan Sun Oil builds the SL series as one oil type across a range of viscosities, from 10 cSt to 320 cSt at 40 °C, so the choice within the series is a class decision rather than a product decision. 216.0 cSt places SL-220T in the ISO VG 220 band, which is the classification that lets it be compared with other 220 cSt oils from any maker.
A polyol ester charge is more sensitive to moisture than a mineral oil, which is the trade-off that comes with its miscibility with HFC refrigerants. The Sunice SL series is formulated for hydrolytic stability — resistance to breaking down in the presence of water — and Japan Sun Oil lists that as one of the series' characteristics, along with thermal stability, lubricity and high electrical insulating property. In practice, the way to keep that property working is to keep the system dry: store the container sealed, evacuate the circuit properly before charging, and do not decant into a container that has been left open. A batch certificate of analysis issued with the shipment is the way to confirm the moisture figure on the oil you received.
There are two legitimate ways to buy this grade, and they are not the same purchase. The original Sunice SL-220T is the oil Japan Sun Oil Company blends, and it comes with that maker's documentation. The equivalent we produce at our plant in Foshan is blended to the same 220 cSt class from the same polyol ester base oil type, and it comes with our own batch certificate of analysis. We quote both and we say which is which, so a buyer who needs the original brand for a warranty or a tender can have it, and a buyer who needs the class at a manufacturing price can have that instead. Both ship from Guangzhou on the same terms.
The most common mistake on a grade like this is matching the drum rather than the viscosity class. Two oils that look the same on the shelf can be a whole ISO VG band apart, and the label on the old container is often the only record of what was in the system. The second mistake is converting the refrigerant without changing the oil: an HFC retrofit on a mineral charge leaves the oil sitting in the evaporator. Both are avoidable with one check before the order — send the compressor model and the refrigerant, and we confirm the class against the published data rather than against the drum.
The Sunice SL series runs from 10 cSt to 320 cSt at 40 °C, and the difference between the grades next to each other matters more than the difference between brands. That is why the first thing we ask for is the compressor model, the refrigerant and the operating temperatures, and why we confirm the grade in writing before quoting. It is a short exchange that avoids the expensive version of the same question — a compressor stripped down because the wrong class went in.
A: There is no fixed minimum order — it is confirmed per order, because it depends on the pack size, the quantity and the destination, and a single can and a full container load are both workable. Pack sizes are confirmed at quotation, and custom pack formats and private-label artwork are available as a quotation item, so if your own label has to go on the container, say so when you enquire and it is quoted as part of the project rather than added afterwards.
A: SUNOCO Sunice SL-220T is a synthetic polyol ester (POE) refrigeration oil with a kinematic viscosity of 216.0 cSt at 40 °C, which places it in the ISO VG 220 class. It is part of the Sunice SL series, the synthetic line Japan Sun Oil Company designed for compressors charged with HFC and HFO refrigerants. Japan Sun Oil states the series is used in reciprocating, screw, centrifugal and scroll compressors and in refrigerators, freezers, chillers and industrial refrigeration systems, and names R-134a, R404A, R407C, R410A and R507 as miscible and compatible refrigerants.
A: 216.0 cSt at 40 °C falls inside the ISO VG 220 band of 198–242 cSt defined by ISO 3448, so the oil is a 220 cSt class oil. The class matters because it is the part of the specification that is comparable across brands: a compressor specified for a 220 cSt oil needs a 220 cSt oil, whatever the name on the drum. Replacing it with a lighter or heavier class changes the film thickness in the bearings and the load on the machine. Note that Japan Sun Oil does not print an ISO VG number on the datasheet for SL-220T; the class is derived here from the published viscosity and the ISO 3448 bands, and it is stated so that you can compare it with other oils sold at the same class.
A: By the compressor duty and the refrigerant, not by the drum size. The SL series is the same polyol ester oil type at a range of viscosities, from 10 cSt to 320 cSt at 40 °C. SL-220T at 216.0 cSt is a higher-viscosity grade; SL-170T at 161.0 cSt and SL-100S at 98.1 cSt are lighter. Send us the compressor model, the refrigerant and the operating temperatures and we will confirm which class your system takes before quoting — stepping up to a heavier oil without checking the duty raises the load on the compressor, which is the wrong direction of travel.
A: It is a synthetic oil — a polyol ester (POE). The Sunice range also includes mineral lines: the GS series (3GS, 4GS, 5GS and their GSD variants) is refined from naphthenic crude oil and is used with CFC, HCFC and natural refrigerants such as R22, R717, R600a and R290. The SL series is the synthetic line for HFC and HFO refrigerants, where mineral oil is not miscible with the refrigerant and a synthetic charge is required. The two lines are not interchangeable, so it is worth confirming which one the system was specified for before ordering.
A: Yes — polyol ester oils absorb moisture from the air, and moisture is what shortens their service life, so they are more sensitive to handling than a mineral oil. Keep the container sealed and out of direct sunlight, keep it closed between top-ups, avoid decanting into unlined steel drums, and evacuate the circuit properly before charging. Japan Sun Oil lists hydrolytic stability — resistance to breaking down in the presence of water — as one of the characteristics of the Sunice SL series, and keeping the system dry is what allows that property to work. A batch certificate of analysis issued with the shipment is the way to confirm the moisture figure on the oil you received.
A: Not as a drop-in, because the two are different oil types. A polyol ester is intended for HFC and HFO refrigerants, and the mineral oil in an R22 system is a different chemistry — the GS series is the mineral counterpart in the Sunice range. Converting a refrigerant from R22 to an HFC or HFO gas requires changing the oil as well, and that changeover is a documented procedure rather than a substitution. Send us the compressor model, the current refrigerant and the intended refrigerant, and we will confirm the correct oil and describe what the changeover involves before you order.
A: A technical data sheet and a safety data sheet come with the quotation, and a certificate of analysis for the delivered batch comes with the shipment. CE, CO and transport certification are issued as standard export documents on request. If the destination requires a particular certificate for customs or for a tender, say so at the enquiry stage and we compile the file with the quotation rather than after the shipment.
A: Both, and we say which is which. We quote the original Sunice SL-220T from Japan Sun Oil Company, and we also quote the equivalent 220 cSt polyol ester we manufacture at our own blending plant in Foshan, China — our QSL-220H. The original comes with its manufacturer documentation, and our equivalent comes with our own batch certificate of analysis. A buyer who needs the original brand for a warranty or a tender can have it, and a buyer who needs the class at a manufacturing price can have that instead.

This oil is manufactured and supplied by Guangzhou Qishanr Technologies Co., Ltd., trading as the brand QISHANR. The company is based in Foshan, Guangdong, adjacent to Guangzhou Port, and has been producing lubricants for more than 10 years from its own blending plant. That plant runs at an annual capacity of 6,000 tonnes, which is what allows us to hold stock on the grades we list and quote firm lead times rather than promising on behalf of a third party.
Refrigeration oils are the core of the business, but they are not the whole plant. The same lines produce general industrial lubricants, so a mixed enquiry that covers both refrigeration oils and ordinary industrial grades can be quoted, packed and shipped together instead of being split across suppliers.
This is not the full range. Specialised ester base oils and lubricant additives are produced in-house as well, which is the reason the synthetic ester grades can be specified to a target rather than bought off a shelf. If the grade you need is not listed above, send the specification or the product you are replacing and we will confirm whether we produce it.
Long-term partners get pricing that reflects a stable manufacturing base rather than a trading margin, and the same technical contact stays with the account from grade selection through to repeat orders.
Sunice SL-220T is a 220 cSt polyol ester, so a quotation depends on the grade, the pack size and the destination port rather than on a list price. Send your compressor or unit model, the refrigerant and the quantity you need. We will confirm the viscosity class against the Japan Sun Oil data — including whether your system takes the 220 cSt grade or the class next to it — and come back with pricing, pack size and lead time. A technical data sheet and safety data sheet come with the quotation, and we can quote the original SUNOCO product or our equivalent 220 cSt POE side by side.
