Engine oil VALVOLINE or Shell

'03 GX470, had 240K miles when I bought it just over a year ago. Now on my 2nd oil change at 245K miles with Valvoline High Mileage 5W-30 full synthetic and Fram XG3600 filter. It's quiet and doesn't burn or leak oil.

Shell Rotella T6 15w40, has worked fine in my F800GS for 40k miles.

I would recommended shell ultra 15w50 . KV100 is 20 which is thick as fuck and won't shear down quickly. Mogul 7100 is thin and will shear down to 40 grade and internationally considered garbage oil. Shell is made of group 3+ base oil so its going to perform better.

Valvoline Advanced with black Wix filter!

Rotella 5w40 only. I daily and track mine

Valvoline 5w-30 full synthetic for good cold starts in winter and a royal purple oil filter for good small particle filtration.

On an old e36, 5w30 full synthetic no matter the brand would often cause some leaks. Switched to some thicker Rotella oil made for diesels and suddenly no more leaks.

Use either IDEMITSU Rotary oil or Valvoline Racing Oil.

Valvoline seems to be the quietest oil.

Valvoline oil and an STP filter. Good price and convenient because its at Autozone.
