I'll take it! Anything over 40 is my goal...for now.

I'm working on it! I'm running this tank down so I can get as close as possible to the correct calibration when I DO fill up.

I'd do it just to make sure your fuel system, injectors, and combustion chamber are clean. I can't verify that it'll also help to clean your catalytic converter, but I've heard that it does help those with Civics prone to the problem. I'm in the camp of "it can't hurt anything other than my wallet and may help in the long run...I'll give it a shot"

One thing I've learned about classmates...they're all morons...at least until you get to the graduate level (I have a Master's)...then only half to a quarter of them are morons. Don't listen to anything any of them say. 90% of them will take that diploma/degree and do nothing with it. Most spend their spare time drinking or smoking pot.
Family and friends matter. Your dad even HELPS you with your eco-mods. That's a win in my book! Not to mention, your part about being the one with the fat wallet at the end of the day is AWESOME! Keep rockin' dude!
