Yet another oil discussion -- Best oil for Me.

[white_2kgt]

The motorcraft is very good stuff. I don't use it b/c I can get mobile 1 cheaper and so far blackstone sees no reason to change.

Where do you get Mobil1 cheaper than motorcraft?

Man, Motocraft is like, 3 bucks a quart. Mobil1, the cheapest I've seen it, is 5.

Any reason not to use 5W-30 in Julie's car? (She currently uses 5W-20) It's essentially the same engine. That way I can just buy a crap ton of oil at a time.

eh? I'm paying $5/qt for Mobil1 at sams, motorcraft is $6/qt w/ my discount!

You will be fine w/ the 5w-30, they just call for 5-20 for emissions reasons.
