Old cars had no gauges. Hell motorcycles started getting gauges in the late 90s hahaha :lol:i get like 24mpg somethin like that sometimes more but i do it by filling it an using the trip odometer an drive till the light comes on since i have no fuel gauge lol
I had a GMC Jimmy that bounced around with braking and accelerating, and turning....it sucked.I remember the older Suburbans would bounce even during braking, so I'm not too trusting of the accuracy. Keeping it off E is a good policy anyway
False. Running your car to EMPTY could potentially burn up a fuel pump, but liquid is liquid, whether you are pumping it out of a container with a gallon in it or 100 gallons. The pressure on the pump does not change unless there is no liquid in it.running your car really low on gas is very hard on the fuel pump.
I'm getting between 30 and 35 mpg depending on my driving style that week. I spend most of my driving time on the highways, though.yeah i get all your guys posts but i asked about one gallon.
for the past 6 months or so ive measured by trip meter.False.

For those wondering why a gallon at the middle of the tank is not the same on the gauge as a gallon at the top or bottom of a tank, it's simple. Your gas tank is not a perfect symmetrical cylinder. It's smaller at the top and the bottom than it is in the middle. Using a gallon when the pool in the base of the tank is small will make the float gauge move down faster than if the tank was half full. Think of the amount of ice cream at the top of the cone versus the amount when you get to the bottom. Fuel gauges are not a perfect science—they are actually pretty primitive mechanical measuring devices, all things considered.
You need to measure your mileage by the tank, not by adding a gallon and adding up the miles traveled where the gauge moves.
Looks like you have covered just about everything else that is easy to troubleshoot... this is where I would go next. Most muffler shops can do a new O2 sensors for you if you don't want to climb under there and do it yourself. I prefer to leave exhaust work to guys who do it every day, but that's me. I'd buy the new sensors online and bring them to the shop.02 was never done (to my knowledge)
