Then there are the rumors that some distributors use a sub grade gasoline for blending. I don't know how true that is.....
The ultimate solution, and what I plan to do, is has the blend sensor in the fuel return line to measure the true Ethanol content in your tank. That is how the factory flex fuel vehicles do it. |
he is right.
during the winter you will see e70 cause the car wont start in cold weather with e85,
e70 is around 100.5 oct. and e 85 is around 102 -104 depending on the pump.
so buy 20gallons of winter mix. put it in air tight can and wait till motor is dont. then tune it on that. then no matter what you are safe.
