93 J30 How many miles on a tank?

[lfootmatt]

Gas gauge seems to be off.

Fill it to the stop and it only reads slightly above 3/4.

On the empty mark I can only put about 12-13 gallons in it.

Roughly 300 miles per tank is what I'm getting.

so far I'm getting 22mpg on mixed driving.

Thanks, Matt

Mine did that for some time too. I started using premium gas at chevron and now the needle goes up all the way for some reason. Theres a 19 gallon tank so you can go for about 60 more miles safely.

Only if you want to repeatedly stress the fuel pump and shorten its life!

not saying its good to do every time...but its safe to go just in case you can fill up at the time.

The fuel warning light goes on with ~3 gallons left.

Thanks for the info.

I'm not opposed to filling up early anyway. My mechanic back home, Gene at GT Automotive in Kansas City, always told me keep it above 1/2. He said that this would eliminate most if not all fuel related failures.

Gene is smart, totally competent, and can be trusted. A rare combination. He would hire a mechanic every couple of years, only to fire them 2 weeks later because he could never find anyone that would work to his high standards.

Just for grins I'll take it down until the light just turns on so I have an idea where empty really is.

Thanks!

If you are in KC and need a good mechanic call Gene he is doesn't have his own shop anymore but works at Vee Village and does stuff on the side.

Taking stuff to him felt like you were doing it your self but had the right tools and know how!!

My J30 is only getting about 200 miles until my fuel light goes on. Once that goes on, I usually fill up and I fill about 18 to 18 1/2 gallons. I think I might have a problem....

[j30t]

I think so...I can go 340 and only fill 17 gallons.

That sounds too low. That's about 11 mpg.

In my car, doing strictly city driving, I can go about 250-270 miles before the gas light comes on.

I don't like for the light to come on. I normally gas up with 1/4 tank left.

Air filter, throttle body cleaning, Chevron Techron. That will definitely help things.
