15 minutes on the highway going average 75 (my speedo is off by 5, so it
shows 80...) and 15 minutes in the city. I cant get more than 300 miles
off a tank, which is 17.5 mpg.
However this is on 89 gas, since 93 makes absolutely no improvement.
I use 87 octane and pull 1.8 bar at sea level no problems. Just did a trip
last weekend that was 456 miles between fill ups, mostly hiway cruising
80ish and got just over 25mpg. It should be better but I still have the
studs on. I also see no improvement on 91 or higher octane. I see 20ish
driving with a heavy foot for mixed driving.
I would say that if your exhaust is not black as you say, then you are not
running rich. Have you pulled a spark plug and checked it? Be sure it is the
correct type for the car. F5DPOR as I recall.
