Hey bitog.
I noticed that none of the major oil brands have 5w20 A5/B5 oil while all of the 5w30 do have A5/B5.
Knowing A5/B5 helps with fuel dilution, I hoped to grab an A5/B5 5w20 for the next scheduled dealer's maintenance and couldnt find one.
Can anyone explain why a5 is only available in 5w30 flavor?

Acea is run by the French, they don't usually run 5/20 weight. Typically they use 30 and 40wts

If it were me, I'd just run the 5W-30 A5/B5.

A5/B5 requires HTHS of at least 2.9, which no 0 or 5w20 can meet.

A1/B1 had an exemption for 0w20 and 5w20, where the minimum was 2.6, but ACEA dropped A1/B1 from the latest sequence and replaced it with C5.

Use a 5w30 A5/B5 smile
