What to follow API or ACEA rating?

[Ry_Tower]

in 2024...

suppose you got an old fashioned engine i.e. no turbo, no DI

would you rather get an oil rated w/ the latest api SP (with no acea rating)

or an older api SN but with acea a3/b4 rating

I'd get the older spec engine oil. Old engine requires old oil qualities. Resource conserving or energy conserving oils might not be good for those old fashioned engine.

I'd only get the newer spec oil if it is backwards compatible.

check out the lubrizol comparison tool:



actually my engines are compatible with "fuel economy" low HTHS oils like a5/b5

but for wear protection, SP is an improvement over SN. but a3/b4 is still better.

My car requires at least a5/b5 as well. I'm mulling whether to use an a3/4 engine oil as well hehe

engine oil is just base oil plus additives, and the additives are made by just FOUR companies (all reputable). so in a perfect world any oil that passes certification should be good. but would you really wanna be using oil from brands you've never heard of e.g. oscar, samic, etc 😅

Worldwide, there are at least 19 or more who makes lubricant additives. I believe that the four you're referring to are just the ones used by the top US-branded lubricants.



From The Motor Oil Geek channel.. context is again, the US:


As an example, I would think that oil manufacturers like Liqui-Moly would rather be working with German additive manufacturers like BASF or Evonik.

Not as good as the old API SP for LSPI though, which is important for old-school turbocharged engines.

Wear/sludge/deposits can all be solved by changing the oil regularly.

The new stuff seems good for newer economy-focused engines run on an extended oil-change cycle.
