I'm questionning the precision of my fuel gauge..

Full ( it means I can see the gas in the filler neck), it reads about a little bit over 3/4 of a tank.

I drove the car close to 280miles and the gauge was still up about 1/4..

Any idea what could be the range of our cars??

I know it depends on the driving style, but let say cruising at 65 on HGWay, 4 speed, mild cam, and headers...

Merci!:squareeye

I wouldn't trust the accuracy of the gauge. If it doesn't read full when it really is full it may not read empty when it's really empty. On the other hand, with a tank capacity of 15 7/8 gallons then your range simply depends on your mileage. Mileage varies according to driving style, city vs highway, engine tune, tire pressure, etc. At 20 MPG you should be able to go 300 miles with a little in reserve. 25 MPG will get you 375 miles. I wouldn't count on getting much better than that.

Sorry, I see you're in Canada. I don't know if you use kmpl or liters per 100km. The tank is 60 liters. I'd expect a range of 500-600km on a full tank.

Hey, that's ok, we still mix km and mile up there!!!!

I red in a Portofolio on Datsun that the range should be in the vicinity of your numbers, around 300-3335 miles.

Cheers!
