switching from conventional to synthetic for mpg?

[wemay]

I have never noticed a difference in MPG when switching between syn, conv or blends.

My vote would be for M1 0W-20 AFE or PP/PU 0W-20

with Amsoil Syn gear lubes for the trans and rear diff

Wow thanks for all the input everybody! Sorry it took so long for a response work has been crazy. I will take all of this into account when making my decision. I don't expect a miracle with switching but any little improvement is ok with me. I stay ontop of all tune up maintenance and check my tire pressures regularly generally keeping them a few psi high. Will be doing the change within a few thousand miles and will also be switching trans/diff fluids to syn as well. I also have to do a FULL brake job! That is going to be fun and expensive! I am glad to see i found a knowledgeable and helpful community!
