Lamont- You sound just like my uncle with the F series Ford. He says "for the most vehicles PYB, Mobil 5000, GTX, or any good dino would have made his old Ford last just as long as the very best A*******l brew." He doesn't buy into salesman's tales, or marketing hype.
He says use the recommended grade oil, change it, change the filters, and drive. I remember him asking a know it all type pushing expensive oil to prove him wrong, he's still waiting. I'm glad he set me straight, for a while I fell for he hype.
