Favorite Motor Oil

[imported_Smoker]

Mobil 1 rules .. its strangely much, much cheaper here in the USA than back in the UK.





Same oil .... different customers.







I wouldnt change Mobil 1 any more often than every 10k tho ... its such slippery stuff you would really be wasting your money.



I ran a 4AGE on Mobil 1, put plenty of screaming high rpm miles on it (redline = 7600rpm) and the oil was still good as new.

Mobil 1 and valvoline all the way.



I know people that use the amsoil tractor synthetic transmission oil in there jeeps its supposed to last a while.
