mobil 1 is probably the best oil in the petroleum world imo.

Mobil 1 has changed alot in the past few years... for the worse.
It used to be a top oil but If you look at the current market, the UOA results, and prices of oils, Mobil is just not the value it used to be.
Mobil is no longer a "full synthetic" as you would think, its more of a blend.

it's always been a blend, last i knew the only two true full synthetics are amsoil and royal purple, all the others have some sort of petroleum product in them.

Mobil 1 used to be a group 4 synthetic, but now it's a highly refined mineral oil basically.

The only other cheap/affordable group 4 I can think of is Castrol Syntec 0w30, the german made stuff.

castrol still has petroleum products in it making it a group 3 synthetic, it lasts longer than regular oils but still breaks down way faster then the group 4 synthetics.

wow glad i clicked on this one. i have used M1 TDT and thought i was getting full syn.........like yall said i have used it for many yrs. i didnt know about this recent down fall for M1

so its not a FULL SYN? i have used amsoil also .........so amsoil and RP are the only full syns out there?

yes amsoil and rp are the only true full synthetics as of now.

Penzoil Platinum is a really good synthetic also.

i'd rather walk than use penzoil.
