heating fuel

[mikehallbackhoe]

will heating the fuel in a carbureted vehicle improve mileage. what temp should it be heated to?

GS does have a search function; it's been experimented with plenty. Nothing came of it.

The Clencher is right on this one... Some claim its worked, but their mileage gains still seem to be within the margin of error IMHO. In any event, it was nothing spectacular. Plus by heating the fuel you increase the chance of engine fires, depending on how you heat it.

Also, on a carbed vehicle as you are asking heating the fuel will increase the chances of vapor lock.

cold fuel has more power. some cars run a fuel cooler thru the AC so on hot days you reduce risk of vapor lock and maintain power.

Why would cold fuel have more power?

I can imagine that cold fuel could allow you to make more power by using more fuel, but not that the fuel itself would have more power.
