Are you brand loyal for motor oil?

Probably 35 years of M1 myself although most of it between 5k-8k miles - I do stray when I find another good brand on clearance/sale … Or if I'm buying "charity oil" for my son. (got him some STP on sale the other day - Amalie I think, it was Dex 1.2 for a 3.6L Dodge, LoL) ...

Mobil1 Oil full synthetic

Engine was still VERY strong with 189k miles when I rid of it No oil consumption (transmission broke)


(verified by pulling the catalytic converter for a replacement had damaged by a misfire from damage fuel rail)

my newer car I use it as well I want to get 200k miles out of it as well I bought it at 84k miles has 90k miles(pretty soon in less then 50 miles)


I have a also switched to Mobil Fuel as well 91 octane

I'm comparing it to chevron MPG wise

good engines are not fussy with oil, think Toyota.

Even the Toyotas that are susceptible to stuck rings and consequent oil consumption?

They no doubt put XOM to the task on making TGMO ? Why ? … if they can run off peanut oil …

I think back to their sludge problems. They make a great engine, but no one is perfect.
