Hey guys,
ok time to do an oil change on the Escape. 3.0L V6. First time ive changed the oil and im going to swap it over to synth. Ive always used Mobile 1 in my previous imports but this doesnt spin anywhere near as high in the RPM. Id still like to use synthetic bc it doesnt breakdown as fast but i dont know if i need Mobile 1 $$$. What do you guys use and how much is it a quart ? Thanks guys (and girls)
what will be best depends on your habits of changing it, and how you use it.
If you are changing it via the light on the dash, or according to the owners manual, you'll be changing it long before a conventional oil will break down to the point of not lubricating like it should.
If you are going to run synthetic, make sure to extend your oil change intervals, otherwise your just throwing money away.
I run mobil 1 in the 8.1 to try to help MPG's and prevent scuffing with the long stroke.
The diesel gets good old 15w40 rotella
The 540 gets castrol HD 30.
