What oil API rating is suitable for a diesel engine?
What oil API rating is suitable for a diesel engine?
For most diesel engines operating in New Zealand, an SAE 15W-40 multigrade Diesel Engine Oil will be suitable. This allows starting down to -20o C and continuous operation up to ambient temperatures of 40o C. As well, SAE 10W-30 multigrade DEOs are available.
What is the most current API service classification for diesel engines?
The current API Service Classification is SN The suffixes (0, 5, 10, 15 and 25) followed by the letter W designate the engine oil’s “winter” grade. Look to your owner’s manual. It specifies the viscosity grade required for your car’s engine. Today, the most common grades are 5W-30 and 10W-30.
What does API stand for in diesel engines?
API – American Petroleum Institute This defines whether an oil is suitable for gasoline or diesel engines. Gasoline engines: The service level category contains two letters. The first letter, S, indicates the oil is for gasoline engines. The codes are as follows: • SN: For vehicles manufactured after 2010.
Can I use API SN instead of SJ?
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 API SJ?
API Service Category SJ was first introduced in 1996 for use in gasoline engines and is not suitable for use in engines introduced after 2001. API SJ oils are typically high HTHS (≥ 3.5cP) SAE 10W-40, 15W-40 and 20W-50 based on API Group I or Group II base oils.
