'11 S 120k miles. I just tried Castrol 10w-40 high mileage because 5w-30 high mileage eventually ended up being consumed. I say eventually because for about 1500 miles it was fine.
Anyways, my oil light comes on at stops. Gonna have to go get it changed tomorrow.
DAMNIT

 

are you using full synthetic? and OE filters????

frankly I find this surprising . . .

maybe some one will teach me something with their answer?????

 

It's a synthetic blend. The 5w30 was a full synthetic top of the line
