on Mobil's website, it seems to rate higher than Mobil Super Synthetic but below Mobil 1...seems to be priced right about the same price as Mobil 1 when on sale...
I'm having trouble understanding why one syn is good for 7500 miles, one good for 10k and one good for 15k if they all are 100% syn from the same company??
additive packages...why are there several different grades of gasolines at your favorite gas station...additive packages (like octane)...
in the case of motor oil (unintended pun) different oils for different price points...they are all synthetics from the same company but not all the same synthetic from the same company...Chevrolet makes the Tax and the Tahoe but they are not the same...
