I don't think so but we'll never know exactly what it contains as the additive packages of motor oils are closely guarded secrets.

Mobil 1 does use polyalphaolefins (PAOs), and as I say a proprietary system of additives.

Why are you switching back?

However you won't harm your engine by switching from a syn to dino ( except some of us believe that syn will do a better job protecting your engine from wear and tear.)

BTW, I heard today from a Ford service tech that you do your engine and wallet a favor by sticking to the 5w(or 0w)-20w rather than a 5w-30w oil. The less viscous oil actually increases the life of the engine because it need not work as hard pushing through it.
Also, the less viscous oil gets better mpg and produces less harmful emissions.
