cutting regular gas w/30% E85 probably results in say a 10-12% mix of ethanol over all ?
You can buy that at the pump anyway. Cars have been running 10% ethanol for years.
Myself being from the midwest, "gasahol" has been standard fair since the late '70s.
You do not get the power or mileage out of it, the biggest reason you are not seeing any "negative" issues is your truck has the ability to handle the timing and mixture issues on it's own...... at least while the ambiant air temps are cooler.
once the air warms up, you will experiance detonation if you do not adjust base/static timing. Your Turbo engine will really like that.
I know this from when I moved down here 10 years ago. '87 Toy pickup, carburated. ran like ass once I got NC and burned all the gasahol out, then when I went back to visit in Illinois, it again ran differantly (lot of detonation) . everytime I had to adjust the timing or run straight gas while I was there.
Gasahol (now known as E10) was the "cheap" fuel in Illinois, subsidized by the state and sold on every pump. of course, the state has made up the cost differance in fuel taxes, so what you are paying for straight fuel here is the price of E10 there now.
You may want to experiment further before you do any damage to the internals of your turbo engine.
As for the cleaning benifits, not really, about all it'll do is absorb any water in the fuel system and allow it to burn thru.
Running it in your power equipment, most small engines will damn near run on water, they are designed to run lean, for emissions reasons. again, air temps may cause issue once temps warm up you may experiance "vapor lock" in some equipment as the ethanol vaporizes and boils in the carb or fuel line due to high heat.
these are MY experiances, I'd burn E10 without question, all my junk is now computer controlled so I don't have to dink with it to make the change.
As for Transoprt, at one time, the trucks would go to the ethanol production facility load up with ethanol, then go to the fuel depot and top off with gas, then deliver to the stations ( is how it was done before E10 became "popular" )
Id' bet they are being a bit more efficient with the blending now, and is probably a more accurate blend as well.
