I've got a GM truck I've had for over 10 years and it's flex fuel. I run anything from E10 to E85 in it and have had no issues, no lights, no nothing.
Yes mileage changes a bit as the E content goes up. But with the price difference being so large it's still worth it. E30 has always been a pretty good happy medium. I either get it at a blender pump or mix myself half E10 and half E85 (ish)
Yes my truck manual says for "best performance" to pick one blend and run it a while but that's only for ideal MPG. Not ability for the truck to run well. |
