Once it gets down around freezing i should be set. Only one tank thus far but i may gain as much as 10%!
I agree with what you're saying. With colder temperatures coming I will not be as worried about doing a complete block of the radiator inlet. However, when it warms up I will definitely be more cautious. Does anyone have experience regarding lean conditions and turbocharged engines creating hot spots on piston heads and creating a hole through? Any info is greatly appreciated.
