How many miles before oil change

[michael lang]

My opinion is you can never do too many oil changes. I think I average about 2000-2500 miles between changes. I don't put in any MOAs and I give the used oil to one of my techs who pours it into his heater for his garage. Since there is no additives, and it is relatively clean it burns extremely nice and helps him keep his garage warm in the winter. So there really isn't any waste.
