I have been running my homebrew, 100% (B50-60 in the winter) for almost a year now. My own rough estimates show around a 8-10% reduction in MPG. Feels like a corresponding percentage in power reduction. Doesn't matter to me though, knowing that it is better for my engine and its fuel system.
There are other biofuels under development that may get better mileage than petroleum distillates (diesel, jet, etc).
"Air New Zealand is coming out in strong support of alternative fuel, saying that more than 3,000 pounds of fuel can be saved on a 12-hour flight if that flight is flown on a jatropha-seed-oil biofuel blend instead of straight Jet A."
B20 is about the same price as diesel right now at a local station. if I use some B20, say half a tankful, would I expect to see an increase in my feul mileage?
If the vendor is selling the B20 for the same price don't waste your money on it. You will lose MPG -n- power. The vendor is taking large profits due to the tax incentives on bio blending,when it should be cheaper than staight fuel. Many of states have as much as $1.50/gal on the bio sold through there pumps, these include state and federal incentives. Bio is cool if it is cheaper otherwise not really a value. I'm not against it just letting you know that most vendors are selling it only because of the tax incentives that make it profitable for them. Truth is without the government tax credits it wouldn't be around. Which we all pay for.

I've not noticed a drop in mpg using b-20 and I 'hand calculate' my mpg after each fill up. I ran b-20 until the local station raised the price, now B-20 is about .15 cents a gal more than #2 diesel and #2 is WAY to expensive as it is...It don't look like that 'Hope and Change' is working out so well. Or is it?
