11.52 gallons... how much was in the tank?

[jonismyname]

running a bit low the other day. put in 11.52 gallons of fuel. any idea how much further i had to go before stutter and fail? how much have you put in your tank?

don't tell me it's bad for my fuel pump. i know that. it's common knowledge. thanks though.

ever ran out? what'd it take to fill up again?

[eTiMaGo]

I think the tank capacity is about 11 and a bitt gallons? talk about running on fumes!

[CTScott]

11.1 is what the manual says for capacity. Either the gas pump was miscalibrated, or you had 1/2 gallon in the filler pipe.

[jonismyname]

i've gone over 11.1 before, both by scan-gauge and actual gas that went in...

[jonismyname]

i assume it was the filler neck (i don't top off) but was wondering if anyone's gone further?

[Lafiro]

Yeah I know the other day I pushed my car to the limit without gas.

Ended up putting a total of 11.5 something gallons in.

Don't know how that was possible, or if the gas station is making money off the pump.

[CTScott]

If you do the math, the filler pipe adds about 0.3 to 0.5 gallons to the capacity.

I did 11.5 gallons on a tank one time. It was also my record range on a tank - 502.4 miles.

jonismyname,

You do realize that running the fuel to that low is not good for the fuel pump. Since the in tank fuel pump normally to surrounded by fuel it uses the fuel to transfer away the heat. The pump isn't as efficient when to transfers that heat to the air in the tank. Give your fuel pump a longer life re-fuel at the half empty level.

I put in 11.6 gals once, but that was when I used to fill it up to the point of slooshing out the top. Still, I've gotten 11.4 gals in more recently when stopping after the second cuttoff...

Cheers! M2

Hey, did you know that running the tank dry may be hard on your fuel pump? :biggrin:

Anytime. :biggrin:

folks disregarding original post can post above, they've already got the ball rolling...

how much heat do these disperse into the fuel anyways? compared to the heat that's carried up and out of the pump with the fuel?

maybe someone needs to create a cooling system for the in-line out of tank gyrator type pumps i sell? carter and holley got some news coming to them...

on topic- it appears 11.5 is the ultimate cutoff... i wish mother toyota could've incorporated a slightly more accurate fuel gauge... now i have a better idea what to track with the scangauge...

I just filled up the tank with 11.5 gallons after 400 miles! How is 500 miles even possible?!?

Welcome to the forum, blown... :smile:
Just a heads up. That thread is over 3 years old so it's likely no one who posted there will answer. But your point is well taken, 40 mpg is far more realistic than 50.

11.1 is what the manual says for capacity. Either the gas pump was miscalibrated, or you had 1/2 gallon in the filler pipe.

Didn't you do a calculation at one point to determine what the absolute maximum capacity would be to the top of the neck and came up with 12.8 gallons? (I know, it's not recommended/safe/etc. to go past the click) The 12.8 seemed really accurate to me because I once ran out of gas pulling into a station to get gas, and filled up to where I could start to see the gas in the neck. The total was 12.777 gallons.

Yes. This thread was from two years prior to me doing that though.

Going really slow, only taking long trips, and using a ton of hyper miling techniques. My best is 47 mpg, backed up by 45 the next week. The only two weeks where 90% of my mileage was highway.

If you can keep the engine revving at about 1600 rpms in fifth gear all the time, you'd get sensational gas mileage. You'd also scare the ever living daylights out of anyone driving with you and piss the hell out of everyone else on the road.

[turblown]

Lol...okay. I guess that makes sense. I got 400 miles with a combination of city, highway, 3 other passengers at times, occasional use of the AC and squealing the tires around corners. :smile:

[Amdkt7]

50 mpg x 11 gal = 550 miles. Hard to do 50 MPG for very long, but I do that on some trips home from work. There is an elevation drop (around 500 feet) that helps a lot. Never drive highway, around 45 mph seems to be the sweet spot for me. I coast down the hill, engine idling. I have less than 2K miles, so break-in is not complete. I got 38 and 40 MPG the last two tanks. Mileage drops when driving 70 and carrying passengers (38 MPG for the trip).
