True that my 3K oil changing mentality is coming out of the "76 F-150 carburetor engine '70's when I did send in my 10,000 mile oil Amsoil in for an oil analysis and it came back as 10% fuel dilution, a totally depleted lubrication package with metal particles and with a note to get rid of it ASAP. Never again Amsoil and never again 10K oil changes.
You can't blame Amsoil for an incorrectly running engine. 1976 carbureted engine ... really?? Can you tell me that nothing has changed in the last 35 years!!
