Mobil 1 4T

[rangerfan24]

Im a newb but here are my questions:
I know Mobil 1 is a group III but is Mobil 1 4T a true synthetic? I have an older car that specifies a 10W-40 oil, can I use 4T in it(it has no catalytic converter). Can you mix 4T with regular conventioanl 10 W-40? Does 4T protect more then the fake synthetics? Thanx

Yes, it's a PAO/V based oil. It's an excellent oil along with the 20w50 V-Twin.

Mobil 1 is a blend of synthetic base oils. Some are IV/V and some use some Grp III/V etc.

Who told you that? Can you provide a source for this?

Mobil does not answer that it is pao, if it was, they would have proudly stated it.

Plus if castrol can sell a cheaper fake synthetic oil for the price of a real synthetic, why is mobil gonna keep selling reals synthetic.

And if both Mobil 1 4T and Mobil 1 are synthetics, and 4T just has the friction modifiers taken out, why is it 3 bucks more? Because 4T is probably true synthetic, while Mobil 1 is a fake synthetic. Granted, Mobil 1 is a really good oil with good cleaning agents

To answer your original question, check the API rating of the 4T, should be SG, which is fine for cars without converters. Not really anything therre to hurt.

Look at the specs. It's Group IV/V.
