A couple days after putting the redline si-1 in my tank I got a p1450 (fuel vacuum purge) code. The purge valve is new. Not sure if it’s coincidence, or if the cleaner somehow caused the code!
Yeah I usually use 91 with good results. 93 sometimes. From reputable gas stations
That’s what I started thinking after I bought the stuff. I’ll see if anything feels different after running 2 bottles.
@lakestone
I just got some bottles of redline si-1. This could help if the injectors aren’t spraying properly, but would it do anything if one is leaking?
I might replace the injectors then. Maybe try a fuel cleaner first and see.
Ford calls for 5w-50 in the car. What advantage does Redline have? AMSOIL Signature Series is easy for me to get and the price is good.
Yes this sample was taken during an complete oil change.
