Shell is even more expensive (4%) in my area.... Not that cost effective.

So far, my mod costs almost no money except transmission fluid. That is maintenance cost. I agree SG can improve my FE, especially when I drive in city and accelerate. Highway cruising has nothing to change since I can't drive slower and I drive 80% highway. So, I expect SG will bring me another 1 or 2mpg. Besides FE improvement, SG can help me to monitor coolant temperature, so I can fine tune the grille block. It also tells me if any sudden mpg drop happened. I know it is a great investment. I will buy one after someone rent my house Hey, Zman, have you bought one yet? Also, congratulation for the good last 3 tanks!! What have you done besides changing the lighter rim?

Next tank will be filled up on Friday. I hope getting better result since more highway driving in the week days.
I haven't bought a SG yet, and I have no aero mods. I imagine new oil and a better fluid could help. My commutes has no interstate driving, and a little highway.

I would like a tasteful looking upper grille block (not tape), but haven't thought about how to do it.

I do have a K&n CAI, I have no idea what it does besides make a good sound.
