Also I don't think that XOM would weaken the formula if they knew they had a winning combination that was driving consumers to use their products.
It's pretty impressive to have a long list of manufacturers that use your product as a factory fill and to have people driving a million miles on your product with the original engine.
Sure oils were different 10 years ago, but since then they have tweaked the formula and picked up more manufacturers that are using them as factory fill.
True, but I dont necessarily chalk up quality to factory fill, and that applies to the Toyo branded Mobil oil.
If you look at the current market, the UOA results, and prices of oils, Mobil is just not the value it used to be.
Lets face it, you could run any brand name oil, with an OEM filter and 5k OCI's and NEVER have a problem. If that's all we were worried about, then we would not be here
Im gonna give Amsoil 5w-20 a shot for awhile.
