pw injectors and fuel miliage

[rdodd]

I installed pw's in my 92 about two months ago and noticed an instant power increase over stock but can't tell for sure if my miliage changed. The only time i kept track of miliage was on a long trip and i haven't traveled much since the pw's were installed. Has anyone done a good comparison of miliage after installing pw's. I read somewhere that some people were getting worse miliage with the auto trans. trucks after the pw's. Does anyone have any information on this?

Power takes fuel. More power, more fuel.

I have the PW injectors and the mileage has increased slightly, but I am not sure whether that is the result of the PW injectors, because mileage was increasing before the PW injectors. What I have found that since I installed the PW injectors I developed a tendency to step on it a little harder - so who knows?

Mine went up slightly but I had the pump rebuilt and the timing set right about the same time. The MPG could have gone done a little and I still would have been happy!

I agree with Al. Since mine went in, I tend to play with it a little more (the power!!!!). Actually after a year of having them in I would say mine has stayed the same. 18. 5 to 19. 0 combo city and hiway driving. I never have pulled much so don't know about that. I do believe that we Ato trans guys do get a little less milage anyway.

I have found that with the Lucas injectors I get a noticeable swing in mileage. If I'm in traffic I will see around 19 mpg on a tank. With no traffic and highway speed of about 10 over I see 22 mpg on 4 tanks that I have done trips on since my mods. The old mileage was around 20 mpg.
