Have Mobil 1 synthetic in my car can I go back to regular 10W-30 ?
Is that possible ? I just believe my car burns alot of oil and 10W might be better for it right now with just daily driving and going everyday back and forth 1 hour at a constant speed of 85-90 mph...thanks
The forged pistons in the R allow a lot of oil blowby when cold. To answer the question at hand yes you can switch to dino oil ,but thats not gonna solve your particular issue.
no, but i am sure he would rather spend 99 cents a quart opposed to 6 bones a quart. you should be ok. i was on the same boat.
