Do you think there is any advantage to one of these "higher milage oils" or no?
If you're engine is in bad conditon, I'm sure the max life could help. Personally I used mobil1 at close to 100k miles. I did the change to mobil1 at ~83k miles, so my engine wasn't even using the good stuff it's whole life,,, in fact is was probably using 10w-30 and the car is spec'd for 5w-30... But I don't have problems now and I like the mobil1.
