Ford Technician here,
I really believe in Mobil 1 synthetics. I have used it in my tour from when i bought it at 28,000 miles till now i have 42,500 miles.
pros- longer engine life, decreased wear,less repairs,
runs smoother, cooler, and feels more powerful.
All due to synthetic oil being perfectlly clean,
(doesn't have to be refined)resulting in less deposits
in the engine.Added lubrication due to syn. additives.
cons-none in my view except price($4.25 a qt.)
and still have to change every 3,000 miles, people
always think they can run syn. oil longer intervals
Not True!!!every 3,000 miles or 3 months!
