Weight reduction works, it only makes a small difference though like most common car modifications IEH intake, exhaust, header for example. The biodiesel conversions I have seen look interesting...

Not sure the acetone is a good idea. It may increase your performance, but it also heats up the combustion to higher than the engine was designed for. It also would increase your compression ratio, which could easily result in knock or detonation, which destroys pistons. (As in blows holes through them).
As for the replacement parts, that's also probably he's gonna need replacements.
As for the weight, it does make a difference, as does tire pressure, by dropping 300 lbs and getting your tires inflated properly you could easily boost 2-3 mpg while driving just like you did before...

Love these videos... As always this is extremely clever, helpful, and easy to do... Now i do have to agree with Andyfox and Pigeonchicken on the tire thing, but i think the point of this video was to show that a spare tire is something that could be taken out without the most dire of consequences for those who actually would want to.

@pigeon- I agree ditching the spare is a dumb idea since the autoclub doesn't offer free replacement tires. I got a flat on my RV without a spare in BFE and had to be towed to a tire shop where I was expertly overcharged. Bad Advice there kip.

Also, turning your car on and off all the time will probably ensure that you'll need a new starter much faster which is pretty costly. I imagine that something like the Prius has a special starter for this reason.

All of the additions and fixes he does to his car cost money and must be done pretty often to maintain that good mileage. If I wasn't lazy and did the math, I bet I could prove that hes spending about the same amount of money on all those expensive replacement parts as he's making up in gas mileage.

I run my car on pure acetone, btw.

If you watched the episode of Mythbusters they tested just this, you wil know that acetone does squat to your mileage...

This guy makes some cool vids.

i'm going to buy some acetone!

great comments - aside from removing the spare. it's not the track - a car weighs 3,000 pounds - removing the spare isn't going to help THAT much and it could leave you in a heap of trouble.... stranded on I-5 waiting 3 hours for a tow??

kip kay is a genius!
