What does API CI-4 mean?

API Service Category CI-4 was introduced in 2002 for high-speed, four-stroke diesel engines designed to meet 2004 exhaust emission standards implemented in 2002. API CI-4 oils are formulated to sustain engine durability where exhaust gas recirculation (EGR) and other exhaust emission components are used.

What is CI-4 Plus oil?

The “CI-4 PLUS” designation identifies oils formulated to provide a higher level of protection against soot-related viscosity increase and viscosity loss due to shear in diesel engines. When originally introduced, CI-4 PLUS identified CI-4 oils meeting a higher level of performance.

What does API SL CF mean?

API SJ/CF. API which stands for ‘American Petroleum Institute’ ‚ is an indicator of the performance level of the lubricant as determined by the type of additive package used in formulating the oil.

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.

Which is better API SN or API 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 CF 4 oil?

Mobil Delvac TM Genuine CF-4 Oil 15W-40 is a high performance, heavy duty engine oil that provides proven protection to diesel engines operating in severe on and off-highway service applications.

What is API SL engine 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 API SL grade oil?

Oils that satisfy API Service Category SL are superior in performance to those meeting API SJ and earlier and can effectively lubricate engines calling for those Service Categories. These oils are typically low HTHS (≤ 3.5cP) SAE 5W-30 and 5W-20 based on API Group II base oils and coupled with ILSAC GF-3.
