Default mileage ? MPG

I have a 95 coupe 6 speed and on my average miles per gallon I used to get about 19.3 MPG, recently I have noticed that I am only getting 18.0 mpg. The only thing that changed is that the car has just gone over 50,000 miles :nonod: I have always felt that after 50,000 all the problems roll in. I think the problem is the car needs a good tune up. I was just wondering if maybe I'm not the only one with this problem. I have also run the car out of gas ( due to trusting the range thing on my dash) it said I had 38 miles till empty which would have definately got me to a gas station, but left me stranded on the side of the road. I s that supposed to be that far off? or is something wrong with my car, it appears like it is running good. Thanks for you time. CMR :cheers:

80K on a bone stock 96 automatic: 22-24 mpg on the highway. Never checked mileage with a lot of city driving.

And I learned years and years ago never to trust a G.M. gas gauge below 1/2 a tank!! They have always een notoriously inaccurate.

When I keep my foot out of the injectors, I'm still amazed at the mileage these stock plastic go carts get. On a trip @ 60 -70mph she gets around 25-30 mpg. I'm at 50K myself, but I did the big tune up last spring, (opti, wires, plugs, coil, coil driver, fuel filter).

Never more than 13.7 around town, but I burn a lot or rubber.
As high as 25 on the highway, more like 22

89 six spd. Getting 21-22 daily driving. Took a short trip of about 300 miles freeway and got it up to about 24.5.
I learned one thing today. I was running errands and the gauge was still lit up about one bar. The car bucked a few times as though it was running out of gas. I was sitting at a light to make a u-turn into a station. I was really praying to get out of the intersection. I made it. The car will never see less than 1/4 tank again.
I don't think my pride could have handled pushing my vette out of an intersection!
Live and learn! :steering:
