Ok, it's not F8L's fault afterall, it was of my own doing. Let me explain. I bought my 1st prius ever almost as an afterthought 7 month ago trading in a 04 BMW 545i. My friends thought I was crazy "downgrading to a prius" & in the beginning I wasn't too sure if I'd become insane either as I was never the type to like or even think about buying a prius. Well, it didn't take me long where I ended up appreciating this prius more & more til I love & adore it now. Also, the appearance was growing on me as I saw other cool prius modded up(thank you to all the other members for your ideas & inspirations). I followed suit & proceeded to mod "my pri" to my liking. The last of which, nearly 4 month ago, springs & wheel package was added. Before the Eibach springs & 17" aftermarket wheels & tires were added, I had been averiging 52 mpg calculated since I bought my pri. & about 48 mpg as indicated on my fuelly after the springs & wheels were added. Well here's the point I'm getting at. I know F8L has experimented alot with both stock & upgraded wheels albeit a G2 but still same logic applies & his experience simply cannot be ignored in this matter. Also, for those whose been on this forum, we know he has been supporting efficiency over performance not so much by word(well that too) but more by action as he is(was) on stock wheels of lately. Well, this got me to thinking & wondering to do what he does(did) & I recall telling him in a thread although I was joking at the time. I may Change back to stock wheels! So I did it(2 days ago). I actually have good reasons for doing it. First, I am almost at 10k miles(9600 actual) & I will be taking it to the dealer soon for the complimentary maintenance & I prefer to take it in w/ the stock wheels just for personal reasons. Second, & more important, I wanted to see what kind of mpg I can get out of my pri. as I believe I was on a learning curve & I could easily beat my prev. 52 mpg avg. but maybe I was fast learner & I hit my peak & I won't beat it, we'll see as this is what's great about the prius, it's fun like this. Lastly, I want to say thanx to F8L for letting me make fun of him a bit & to him & all the other great members here for always making me feel welcomed & providing me w/ all the basic & technical information for which I need. Btw, I tell my friends & others that I actually upgraded from a BMW now.
