15,000 mile oil change

[skeet]

I have to agree with you Rocky. The oil change intervals now seem to keep the dealers happy and we have to keep our "warranties" intact ya know. Mo money..mo money. Heck it wasn't until the 60's that the SAE group even addressed motor oils by giving them ratings. When I sold that Amsoil they had definitive proof that oils don't really wear out. The additives would lose their effectiveness but the oil was good for a long time. Remember using recycled oils in the past? They cleaned the oil and resold it with a few primitive additives in it and made more money. I hate to admit this but I had a 49 Studebaker 4 door. Don't laugh..it got me there and back. Had no oil filter at all an oil bath air filter and the only oil I ever put in it was the recycled stuff. It cost half as much as new and i changed the oil every 1500=2000 miles anyway. Only reason I got rid of it was cause the Studebaker mechanic in town wanted one for parts and he paid me a lot more for it than I paid. I made 90 bucks on that car and ran it for 20,000 miles. I'm glad you had the nerve to say that about oil, Rocky. The way I have felt for a long time, too. A guy I worked with once bought a new chevelle..He ran it back and forth to work for over 90,000 miles and NEVER changed the oil. Just added it when he needed to and kept on driving. Now I don't reommend doing that but it ran for a couple hundred thousand miles with no problems
