Double Your Gas Mileage (It's Easier Than You Think)

Submission for a treehugger video contest.

Note: Driving less (or not at all) also does wonders to shave that gas bill!

I should note that as the inverse of fuel consumption, MPG is a terrible indicator. The difference from 5MPG to 8MPG is more than the difference from 15MPG to infinity MPG.

The rest of the developed world uses kilometers per litre litres per 100 kilometers (sorry about the mix-up) to measure fuel consumption.

How does that make any sense? (as in: please explain it to me, my math skills are teh suck)

Note: I had to fix the comment you quoted, I screwed up the units.

You've basically hit on my point though, which is that MPG is non-intuitive when used to compare the fuel economy of one vehicle to another.

For a given trip, you want to know how much fuel you used:
(Volume of gas) / (Distance travelled)
If your car uses twice as much gas to travel the same distance, the number doubles.

MPG is the inverse:
(Distance travelled) / (Volume of gas)
If your car uses twice as much gas to travel the same distance, the number halves.

It's difficult to describe the relationship with words. Wikipedia has a conversion chart:

I watched the video again, and wrote down the stuff that most people can do to help them:

1: Fill tires to spec (maybe a little extra)
2: Low friction oil's (more expensive though)
3: Clean, Gap or change your spark plugs (if you get new ones, make sure they have the proper gap)
4: New air filter, or less restrictive air intake system (more power also!)
5: Less restrictive exhaust system (just don't make you car sound like a weedwacker)
6: Keep you auto clean of what you don't need in it, and clean on the outside also

I give the guy a nod for what he managed to do but let's face it, he only managed to improve as much as he did because the truck was a disaster when he started. My car is already well-maintained and, at 47mpg, I'm not about to double anything.

meanwhile, the whole ordeal cost him 50X more than it would have if he drove a car and not some jacked up shrine to OPEC.


It's a 5th generation Toyota Tacoma. The V6 is rated for 20mpg. Don't be ridiculous.
