Nissan 300ZX Gas Mileage

Interesting because this year I started tracking MPG on my 89 Z31 turbo. Reason is because my digital display power control unit died (killing my analog ODO) and by the time I replaced it, nearly 10K has elapsed, so to track mileage, I had to record the digital ODO readings at very fill-up. I commute 90miles/day, highway and I average 25mpg using mid-grade and averaging 70mph!!! I think that's pretty good for a very very old car.

I just got my first Nissan 300zx - it's an 85 non-turbo 5 speed with 157K miles.

With the really bad front end components and less than great tires I averaged 29 mpg using 87 octane last week driving to and from work, which for me is all highway travel at 53 miles each way.

It still needs a tune up but it has a K&N Cold Air Intake and filter on it and a new exhaust system so maybe this could be pushing the MPG up.

Recently, on the way from LA to Palm Springs, with cruise control set at 60 miles per hour, I got about 27 miles per gallon. Lately, being careful to gradually accelerate, I am getting about 16-17 miles per gallon in city traffic. At 170,000 miles just got smogged and mechanic said it was the cleanest running Z he'd ever tested.

I get compliments on how great looking this car is all the time.

#10 of 17 fuel problem by marciano1

I have a 1990 nissan 300zx, 2-seater and when I get low on fuel or put fuel in it, it revs up to 3,000 - 4,000 rpms, kicks into 2nd gear, revs up to 3,000 - 4,000 rpms again, but then starts to slow down like its gonna stall out. I have replaced the fuel filter already. If I let it sit for a couple of days after filling it with fuel, theres no problem until it gets low again. Do you have any suggestions for me?
