Rotella T 15w40 in everything from the lawn tractor to the Tahoe. This includes my 3 bikes and numerous atvs. I like it cause it's cheap, yields good results, and I can buy it by the 55 gallon drum if I desired. Haven't changed the oil on the f150 yet but it should be soon.

Hello, just got an almost all original 1985 f150 4x2 supercab w/ 128k miles. Just thought I should participate in this forum. Thanks for having me.
