I'd still go Supertech Full Syn at $17.xx. If Mobile 1 was this price then maybe.

Are these bottles a different formula or is it just a new label?

Haven't checked yet but this seems like a phenomenal deal, especially if I can get the 5W-30 for that price. Thanks!

its different from Mobil 1. Ive read its not really 100% synthetic but is a synthetic blend that might not have the same detergent level.

From the interwebs:
"Full Synthetic" is a marketing term, often meaning it's highly processed (hydrocracked) but not strictly a synthetic hydrocarbon molecule from start to finish.


ive always used Mobil 1, my last two Fords all required the 5W-20 version. im tired of the price hikes and might try this

True it's not, but it's not like one will blow up your engine and one wont.
