I feel the same about oil as ahnyyoungboi.

Hanging out with racemotor guys and road racers will tell you that redline and mobil 1 oils are the most used oil for endurance racing. mobil 1 more for the club racers and such on a budget..but the point being is that there has got to be 20+ years of nothing but positive experience on mobil 1.

the other point was that modern dino oils are blended with pretty decent additive packages and will last for months. It is my observation, as a former import mechanic, that most cars will be fine on 2 oil changes a year. Usually, the people who change it every ten months either barely drive or run into other kinds of neglect, like a coolant related failure resulting in blown head gaskets etc, because they never changed the coolant in 9 years, for instance. the motor usually lasts long enough lubrication wise for something else to go wrong.

I did see some dandies in the service and repair trade. I try for 3 oil changes a year, but i do it myself and it never cost more than about $8-$10 every time.
