5w20 versus 0w30 and gas millage

[crimsontide]

will i loose anything by going w/ a 0w30 mobil 1 R or german castrol versus the fords spec 5w20 as far as gas millage?

Considering the fact that you're only going up by about 1 or 2 cst at 100c, the MPG should not drop much at all. In fact, you might even get better MPG going with a well built 0w30 synthetic compared to a 5w20 blend.

Either one of those should work well, or Amsoil 0w30 also. 0w20 Mobil 1 also shows excellent results in many vehicles too, so I'd consider this one too now that I think about it. There are lots of good choices in oils out there! [ March 10, 2004, 11:23 AM: Message edited by: Patman ]

I am assuming you have a Ford. The M1 0w20 as mentioned above is a very good oil and has posted some great results in the used oil analysis section. Check it out!

I put the M1 gas mileage formula 0w-30 in my Ranger for the winter instead of the recommended 5w-30, but that 4.0 sucks gas no matter what.
