True, this has been from other people's cars (sometimes beyond a 20,000 mile interval) so there's no telling what's going on inside their engines. I've never encountered such from my own vehicles, but then I do burn SAE 30 exclusively... My AMC does tick & clatter on 10W oil, but it's burning a GM 151 (inline 4) with 150,000 miles. No telling how far past a reasonable service life that poor General Motors engine is... My F150 with Ford's 300 (inline 6) just turned 205,000... (I don't think I could have replied to your post without the invention of elipses...)
