What is the S category in oil?

What is the S category in oil?

The API “S” series describes oil standards primarily for gasoline engines while the API “C” series describes oil standards for diesel engine service. A description of the API service symbol and category mark can be found in the Engine Oil Guide published by the API [1875] .

Is API SN better than SL?

As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. API SN to SJ are for the most recent cars, API SH to SA for the older cars. In this case, you need API SL, so an API SJ, lower, cannot be good. SM and SN supersedes SL so both oils can be used.

What is SF 10W40?

Description. This motor oil is produced with high quality solvent refined base oils and a number of additives, to obtain the following properties: – a high detergency and dispersion power. – a strong resistance against oxidation.

What is SF CD?

SF/CD SAE 40. Monograde engine oil for the lubrication of gasoline and diesel engines of passenger cars, with or without turbo. This oil is characterized by a combination of good detergent and dispersant properties, together with a low ash content. applications.

What is SF oil?

Single grade oils like a 30W have the smallest temperature range. An API service rating of “SF” means the oil meets all new car warranty requirements for 1981 and newer models. “SE” means the oil is usable in all 1972-1980 vehicles. “SD” means the oil is good for all 1968-1971 cars.

Does SN mean synthetic oil?

sn= synthetic oil. Most likely ‘sn’ stands for synthetic oil… which this oil IS & meets synthetic oil requirements and standards.

Is API SL oil synthetic?

These very high quality synthetic formulas provide enhanced engine protection longer than conventional motor oils. Sinclair Full Synthetic SAE 5W-20 and & 10W-30 Motor Oils carry the ILSAC GF-5 Certification Mark that meet API Resource Conserving requirements.

What does API SL mean on oil?

SL. 2001 Gasoline Engine Service. Category SL was adopted to describe engine oils for use in 2001. It is for use in service typical of gasoline engines in present and earlier passenger cars, sports utility vehicles, vans and light trucks operating under vehicle manufacturers recommended maintenance procedures.

What is SF 15w40 oil?

Product Description: MOTOR OIL SF 15W-40 is a multi functional mineral engine oil for older gasoline-, diesel- and LGP engines of passenger car and light vans with or without turbo compressor. MOTOR OIL SF 15W-40 is not suited for engines equipped with a Diesel Particle Filter (DPF).

What does SF mean in motor oil?

Now the letters. An API service rating of “SF” means the oil meets all new car warranty requirements for 1981 and newer models. “SE” means the oil is usable in all 1972-1980 vehicles. “SD” means the oil is good for all 1968-1971 cars. “SC” is adequate for all 1964-1967 models.

What is CD class oil?

CD — Diesel Engine Service Oils designed for this service were introduced in 1955 and provide protection from bearing corrosion and from high-temperature deposits in these diesel engines.

What is the difference between SE and SM engine oil?

As the years roll on and oil quality and specification improves, so the second letter of the classification changes alphabetically. SE is a now obsolete, the latest itieration is SM. SE through to SM oils can be used in an SE classified engine, SE through to SL oils cannot be used in a SM classified engine.

Where can I find Sese and SF engines?

SE and SF are old standards that have been replaced. http://www.pqiamerica.com/apiserviceclass.htm You probably won’t have much luck finding them in the US anymore. The newer standards are designed for better gas mileage (which also makes them less desirable for use in a shared-sump motorcycle engine). They’re currently on SN.

What does Sasae SE and SF mean?

SAE is the Society of Automotive Engineers. They’re the group who sets the viscosity standard, not an actual standard. The API service level is in the top half of the “donut” seal. SE and SF are old standards that have been replaced. http://www.pqiamerica.com/apiserviceclass.htm You probably won’t have much luck finding them in the US anymore.

Should I be concerned if my motor oil is SG?

RAY: No, you don’t need to be concerned, Dave. The letter combinations are performance ratings from the American Petroleum Institute, or API. When your van was manufactured, the top-of-the-line motor oil was rated SG, so that’s what Ford called for.
