No, that's 75 miles of burning your fuel pump because it is cooled by the fuel in the tank left

The electric motor driving your fuel pump does not develop enough heat to necessitate liquid cooling. I usually fill up when I have between 2 and 3 tbsp of fuel remaining in the tank, no issues. Ever.

Don't make me sick edwin on this thread.. :P The pump can burn out from being run too long at very low fuel levels. People have actually had fuel starvation during track driving with anything less than half a tank of fuel. My guess is that when the fuel light comes on, that's about when the pump is getting exposed to some air.

p.s. if you had ***** you'd take it down to 1tsp.. including fuel in the lines

Meh, the pump can burn out from just running too long, also. However, from a safety standpoint, I guess it's better to keep the pump submerged because if it sparks, it will not ignite the surrounding liquid fuel, whereas fuel vapor will deflagrate.

How do you know that all of them are?? Don't most people calculate fuel mileage the accurate way by dividing number of miles driven by gallons of fuel to get the car back to full? I looked back through the thread and only a couple people were throwing out numbers like "oh I get 400 miles to a tank"

i know how to calculate mpg. duh...but im sorry if i generalized everybody in my statement. I only meant the people giving us there total miles per tank.

mpg = accurate
miles per tank = inaccurate

Yeah I figured as much, that's why I actually went back and looked through the thread to see if everyone was just throwing around garbage numbers and it didn't seem like the majority were, just one or two people.

It's all good, no matter what we're gettin better mileage than SUVs at least

I got rid of a Mazda B4000 (ford ranger in disguise.. i.e. same basic chassis and drivetrain as the explorer) with the 4.0 v6 for my Protege5.. so good! 13mpg city to 30mpg city, 17-19mpg highway to 36mpg highway.. I never looked back

though I still have the truck.. it's just 6 hours away in CT so I can never really drive it I have no room to keep it at my house in Rochester, parking is tight as-is

I actually took a mileage hit buying the protege. My 92 Cavalier took less gas than the pro.

Also, it couldn't beat a minivan off the line, so I think the trade is fair, haha.

I think he mean "can't", not "couldn't"

unless they are loaded full of children, almost all minivans are faster than any non-turbo 3rd gen protege. I've been burned by enough Siennas to know this lol
