MB 229.51 is only approved for 3 of the 7 groups of gasoline engines that the 229.5 is approved for according to the MB oil approval chart 223.2.

He wrote "229.51 is the diesel spec. It isn't backwards compatible to 229.5 (gas spec),". It is not just a diesel oil. Period. It's a multiuse low SAPS oil. In some cases it can be used in 229.5 applications (gasoline), so yes it's backwards compatible - true not 100%. It's just that you can't use 229.5 in diesels with DPF.
"I wouldn't use the AFL in a Gasoline mercedes because Amsoil says 229.51 spec"
What does this mean? Look at the chart. Some gas engines are OK with 229.51 per MB. Amsoil has it absolutely correct. Please tell me which words to eat(?)
Amsoil has it right
He has it right
You have it wrong
229.51 is not backward compatible with 229.5 and 229.3, so he is right
for 229.51 to be backward compatible with 229.5 and 229.3 then it would have to be approved for all petrol engines...which it is not
Riggaz
No. And yes. 229.51 is NOT just a Diesel oil. That was my main point. But I see your point. It is not fully backward compatible and I agree - and I thought I stated it pretty clearly above, I probably didn't choose my words correctly. MB says it can be back spec'd for certain engines - and that was my point, or why else would have have posted the links? Anyway, kinda glad we hashed this out.
