So looked at Fords and Toyotas in Denver the last week. All of the Toyota trucks, everyone one of them, is now flex fuel. Of the Ford's I looked at, all were flex fuel but out of 600 2014 F150s, surely some of them are not flex fuel.

I will never buy ethanol and actually even though it is 27% less efficient than gas, it is now costing more to buy it with the drop in gas prices. So what is driving this massive push for all engines, most of which will never burn ethanol, to be converted to flex fuel?

I am looking at ordering a non flex fuel truck and waiting the 10 weeks needed to get it. What am I missing on this flex fuel push?

Why do you want a non FFV? As far as I know the power output when burning gasoline is the same, so you don't lose anything.

If you get the tundra, you CAN NOT install a supercharger on a flex fuel vehicle. I have one and while I am in no rush to install a supercharger I would like the option.

My current 5.7 liter is non ffv and has run great with better mileage than others have reported. I keep hearing reports of lower fuel economy and higher service costs with the FFV versions.

Just seems odd that with ethanol now costing more than regular gas, that there would be this huge push on FFV equipped vehicles.

Micky, Probably won't supercharge it, but 504 horsepower would be fun to tap into a few times.

Buy one anyways. If .gov ever forces E15 on us, you will be glad you did.

Gov. mandates a certain percent of gas sold be ethanol. Our former jackasss governor somehow linked Pa. to California's regs and we are now truly screwed. Can't even buy a good gas can here.

I have a 2007 flex fuel Jeep. I have never used E85 in it. I have heard too many horror stories and currently using the flex fuel option is a bad $$$ move as others have stated. Is it true that flex fuel vehicles have better fuel lines and tanks?

Flex-fuel vehicles have fuel system components that are compatible with ethanol - not better, just different. The flex-fuel vehicle engine control module is also programmed for higher ethanol mixes.

There's no reason to avoid a flex-fuel vehicle in any event.

I don't think it's a new push. The FF engines have been around longer than most people think. Including this people. I had an '04 Yukon that I didn't even know was FF until I dug out the sticker in '08 to sell it. Never noticed anything different about its performance, but never put E85 in it either. E85 doesn't generally pencil out in dollars per mile. Pretty soon, I think it will be harder to avoid it in an engine than not. Not that it makes any sense to even produce E85 given the mileage math.

Heard enough issues with the flex fuel Toyota engines that I ordered one with my same old 2008 engine in it. Not in a big hurry and picked out what I wanted on it. Some great deals on 2015 Tundras right now.
