ISLAC & API specs are for cats and squeezing out mpg. With that I think more people here are worried about engine protection which these specs are not geared around.
ACEA revolves a lot more around covering engine protection (look at the link, ACEA 2008 A1 or A5). Pull up the link and look on the graph?
Penz Plat only meets ACEA A1-04 & A5-04 and Ultra does not reference any. People will give Amsoil [censored] for not officially meet a spec why no be quandary on Penzoil.
Does it not bother many to hear "yea we meet the specs but just have not had time to do that official testing thingy"
Valv Synpower and Castrol Edge meet the 2008 A1 & A5 spec.
This is why I have a hard time warming up to Penz Platinum or Ultra although they are likely truly great oils and have excellent UOA's.
Am I not looking at this in an analytical fashion?
