Ok, on the radio, spam on the internet I see all sorts of additives, magnets and other items.

But to the point, I was listening to the radio today and they were talking and talking about these devices that would use water to turn into something that would greatly increase your miles per gallon,

But on the talk show, they did not have anyone call in and actually say they had used any. So does anyone have any real research or personal experience with anything that actually works.

Yes, use the lowest viscosity full-synthetic engine oil recommended for your engine and use synthetic transmission fluid. Mobil 1's products are good examples.

Here are some other tips to improve gas mileage:
