Mobil 1 DOES NOT make a full synthetic and haven't in years, none of the major oil companies do -- sorry they forgot to tell the public when they switched the formula to a conventional crude oil mix. Group III oils cost half as much to produce yet the price on "synthetic" still remained the same or even went up.

FYI "Full synthetic" does not mean it is indeed fully synthetic....legally they can call it full synthetic if it has similiar properties even though it's made with crude base oil. Kinda like saying a certain brand of OJ is 100% juice because it looks and tastes similiar...but really half the incredients are 10 or 15 letters long and isn't an orange tree bi-product

I used to run Mobil 1 in the car but had read about them changing their chemical makeup in their oil and losing tier IV oil status so I swapped to Royal Purple, 2 weeks later I spun a bearing, very probably due to the oil overheating on the interstate.

I'm running Redline now, I've heard good things about Amsoil and Motul also. I'm going to send out an oil analysis with the Redline and then try Motul when I get my next oil change and get that oil analyzed and see which one my motor likes more.

You're the first person on IA that i've seen even mention an oil analysis I made a thread about doing them a while back then another one on how pissed i was when i learned Mobil 1 had gone to the dark side...they had sued Castrol just years before for the same thing and lost so they starting mixing Synthetic with Group III oils but continued selling it as "fully synthetic".
