I'm specifically looking at different oils, in the 0W-20 grade only.
I see some oils that do not seem to carry the ACAE certification (for example, Mobil 1 Extended Performance - https://bit.ly/3fLVNM7), some that specify A1/B1 (for example, Castrol EDGE Extended Performance - https://bit.ly/32Jlbya) and some that specify A1/B1-10 and A1/B1-12 (for example, Pennzoil Ultra Platinum - https://bit.ly/32JjQr8).
Do you think this certification, or lack thereof, matters much when trying to compare differing brands? What about the generic "A1/B1" -vs "A1/B1-10" and/or "A1/B1-12"?
Thank you,
Ed
