Best Oil to use

[Jge64]

I saw how good synthetic oil can be in about 2003. I was the district sales manager for BMW at the time and my service representative brought me a situation that I could not believe. A lady who has never even opened her hood and put 18,000 miles on her lease car, had brought it back in for trade, the oil in the crankcase had completely turned to mostly jelly, the actual crankshaft had cut holes in the jelly perfectly. The valve cover was also completely covered and jelly. We then tore the engine down and micrometer inspected every journal, bearing, crank and top end and everything was still 100% within spec. I became a believer in Mobile 1 syn oil.

Here’s the valve cover of that 18,000 mile car

10,000 miles?! I won't even go that long in our car! Isn’t that pushing the oil to its limit?

Nope its fine.
My car goes 12,500 miles between changes and some cars go 20,000 miles between changes.
I once went over 50,000 miles between changes in a car and did over 220,000 miles in it.
Guy I sold it to ran it for years and probably got it up around 300,000 miles.

I have used car oil zero problems in my old Forza and used that for the rear drive as well.
