It's got nothing to do with engine design.
It's got to do with the oil specifications that the European OEMs
dictate (and the specs that the Asian OEMs -don't- dictate).
Domestic and Asian OEMs still specify ILSAC and API rated oils.
This is the oil companies telling the OEMs how the oil will
perform.
European OEMs specify ACEA oil ratings.
This is the OEMs telling the oil companies how the oil will
perform.
Which of these two above scenarios makes more sense?
GM, Ford, Honda, BMW, Mercedes Benz, Saab and others have their
own oil specifications that owners are best advised to adhere to.
The performance spec of the lowest (now obsolete) ACEA rated oils
far exceed anything that ILSAC and API oils offer.
The current crop of API specification fail the OEM specification
of the majority of cars built since the year 2000.
No, you won't find ACEA rated oil for 49-89 cents a quart and a
$6 filter isn't going to do anything to correct an oil that
doesn't have the HTHS viscosity the engine requires.
Brand name means nothing, various offerings with any brand name
mean nothing. You have to learn and understand oil
specifications and then procure the product specs for any/all
oils you may contemplate using and then READ the label because
while one version of Penzvalvoquakercastrolube -may- meet the
specs you desire, the next one may not. This stuff changes SO
fast it's frightening. What you thought was a good oil 4 months
ago may now be horrible, what you thought was a horrible oil 3
months ago may now be the best product on the market.
