In trying to scientifically decide which oils would be better for some of my old cars, I am needing some info on what spec to look for, and the ideal value for that spec.
I have 2 Mercedes from the 90's, both around 130k miles, that need MB Spec 229.5.
Of these spec values, which ones are most important for that application?
Viscosity Index (is higher better?)
Shear (is lower better?)
NOACK (is higher better?)
TBN ( I know that higher is better)
So which spec(s) would you use to pick an oil, if price is not important. (I like to baby them. They are spoiled brats!)
Counting on some of you "oil brainiacs" to educate me on oil specs!
Thank you.
