I use Napa Gold filters.

I switched from dino to Mobil 1 at my last oil change at 36K. I was getting 14.8 to 15 mpg before the change. After the switch its between 15.5 to 15.7 with a/c in mixed driving. I have noticed no performance problems of any kind. By the way, I do all of my own changes so I know what goes in.

I just ordered the Magnaflow cat-back for my Tahoe. It will be here on Friday. I already have the FIPK installed on my 5.3L. I cant wait to get it installed. I hope it helps out the mpg but it will sound cool no matter what.
