Well I was able to find some Red Line and so far so good. I've only put about 50 miles on since adding it to the tank but I've noticed that the car starts a lot stronger. The idle does seem to be getting a bit better. The throttle response seems stronger. I had to pass someone and was amazed and how fast and smooth the engine got up to speed after kickdown. Could be all in my head but I will be using this additive instead of Techron from now on.
