Need help with oil options

X2 !
nm9stheham got it !

I worked at a Chemical Plant where we made synthetic oil, they sold a lot of it to Ryder Truck. Syn oil for Ford transmissions, rear end, and motor. Conventional oil doesn't stand a chance against synthetic. It won't break down. If you could filter it and get the acids back out you could still use it. After a break-in, I always go to synthetic, a ring's best friend. It will end your sludge problem.

Mobile is the best, but pricey, so I use a brand just under that, full syn and not the Walmart brand. Compare what is said about heat. I only change my filter, add some, and dump it once a year. You gotta get it in your head, it's not regular oil. Why waste it ! And Don't use a Fram filter, no check valve.
