Did you get a chance to see the Mythbusters dirty car vs clean car MPG(which also includes dimples in the experimentation)? They received quite a large difference in fact so much so that Jamie and Adam were speechless! |
I don't think I saw that particular episode of Mythbusters, but I've seen a few, and as has already been mentioned here, their test methodology is not always rigorous enough to truly determine certain things. Since I didn't see it, obviously I can't comment on it in any meanignful way.
But getting your injectors running right has the potential of SUBSTANTIALLY improving things for you. Case in point, my own Suzuki "White Gnat". I bought it for good MPG, but it started detriorating as I owned it. My best highway MPG was 51-something, and I hit 50-something a couple other times. Recently I had a much newer engine installed and a couple other things fixed. Then I went out & tested it with the ScanGauge last night and got OVER 50 mpg at every speed from 50 mph down, topping out at 62 mpg at 35 mph. Just driving around town, not even in top gear, the ScanGauge was routinely showing 40's.
Lesson learned; just having the car running right would probably be a really good "first priority".
Oh - I currently have NO aero mods or anything else on it. Tires not even over-pressure at the moment. I didn't test it at 55, but probably would have hit 50 mpg at that speed, too. (60 was 46 mpg)
