What is CD grade oil?
Generally speaking, most oils have grades such as SF/CD where the C class (diesel engines) is lower than the S class (petrol engines). This is because the oil in a diesel engine is far more highly stressed than in a petrol engine. All the lower API grades are now obsolete.

Can I use SN oil instead of SG?
The “S” category designates oils for gasoline passenger car engines, and the “C” category designates oils for diesel-powered commercial truck engines.

Can I use 10W-30 instead of 15w40?
Don’t sacrifice wear protection for fuel economy. Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for 10W-30 to protect as well and last as long as 15W-40.
What are the grades of engine oil?
There are many different grades of motor oil available, each designed for certain operating conditions. Some common grades that you might be familiar with include 5W-40, 5W-30, 10W-30, 10W-40, 15W-40 and 20W-50. There are also multi-grade oils that are for use in vintage or antique engines.

What is JASO MA oil?
JASO MA: Oils for motorcycles with a wet clutch. These oils deliver the needed friction performance to prevent the clutch from slipping and are therefore non-friction modified. These oils can be used in 4-stroke motorcycle engines where there is one oil system in place for the engine, gearbox and clutch.
Can you use SG oil in an engine?
Oils with the classification of SG and SE are antiquated technology. The API cautions that any oil with a classification of SE should not be used in engines built after 1979. Furthermore, the SG classification cannot be used in engines made before 1993.
Which is the correct oil classification SG or SJ?
Furthermore, the SG classification cannot be used in engines made before 1993. The recommended correct oil to use for all gasoline engines, in any year, is the classification SM. For engines made 2001 and before, classification SJ is acceptable.
Which is the best oil SM or SG?
TOM: Well, since then, oils have continued to improve. They now last longer, lubricate better and hold more contaminants in suspension. And as oils have gotten better, they’ve been given higher designations. SH replaced SG in the top spot. Then came SI, SJ, SK and SL. RAY: And now the best-performing oil is SM.
When did SL become a category for engine oil?
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.
