I managed to get 23mpg from the 97GT manual ast tank. That was short shifting in town and probably 70% highway on a bone stock car with 115k miles. I can't complain about that by any means, but I think there is more in it.
That last tank was on some 90oct 10% ethanol. This new tank, I got regular 87 to see what if any effect on milage the small amount of ethanol has. I read in the archives that some people have seen a significant decrease on that gas. I intend to prove or disprove this theory now.
Aside from that, do you think there would be a worth while increase in milage by replacing the front 02 sensors? I'm sure they are origional with 115k miles, and I'll probably drive the car another 50-60k before getting rid of it.
I was also thinking about some bolt ons for more fun and milage. Am I right in thinking a freer exhaust will likely have the biggest effect? Seems like that happens to give them most power/dollar except for the n2o too. hehe
