Fuel Tank Capacity?

[Keros]

Remember to reset your odometer and know how far you can go on a tank of gas if you don't trust the gauge...

My fuel gauge works reasonably well (I think/hope), but at 450km I start looking for more petrol. My biggest fill was 60L and I was getting nervous about making it to the station.

I ran out an 87 7MGE on purpose back in 95. I put 18.1 in it. They are right, you won't get 18.5 in it. You might not get 18.1 in it.

Is there any truth behind the tale that the injectors will be permenently damaged if you run a fuel injected car out of gas?

I've always been told this by numerous people under the presumption that the fuel lubricates and cools the injectors, and a single moment without fuel and they're toast :1zhelp: Thinking about it though, when the tank sucks dry, the pump is going to try to pump air; presuming it can't pressurize air into the lines to push the rest of the fuel into the engine, the injectors will stay wet and fuel will be backed up from the injectors to the pump, and none in the tank, and the system at a complete stall... if that makes any sense.

doh... guess i'm thinking too far into it :biglaugh:

LOL Engine stops ecu doesn't see an ignition event so the Injectors don't fire

(much the same deal for the fuel pump)

450km? Seriously? Cripes, I'm getting worried when I breach 300km!

Ya, that caught me off gaurd too. I had always thought the GE was 87 or 89 at sea level, 85 or 87 at high altitude. My owners manual proved me wrong the other day.

How many N/A people actually only use 91 or higher?

I ran 93 in my n/a daily

Been a few months since I ran down the supra on a full tank, so I think I should have said 400km. It averages 19-21MPG [imperial GAL, not US] if I drive sanely, which numerically adds up to about 400km on a 55 liter fill... about the time when I'm starting to sweat bullets looking at the gas gauge :icon_razz

I do know I can break well over 300 without worry... but into 400km, now that I think about it, is concerning if I'm out on the highway in Alberta... gaps between towns are measured in hours, so I don't chance it if I don't have atleast 50% more gas than I think I need to make it to the next town with premium.

Sorry Grim, I might have misquoted 450km at breaking a sweat... the last time I had the supra on the highway to burn a tank of gas was last august. I hope you can forgive me

My best fuel economy was 29 MPG, going from Grand Forks BC to Cranbrook, spirited driving on a hot day. Hardly a car infront of me or behind me, +28 degree weather in early august. Best day of driving, ever.

Ya, freeway I could see that, I guess. I don't get much freeway time with my car.

If Toyota wasn't smarter about injectors firing, yes. I don't know of any injector that is just "on" instead of pulsed.The injectors could be damaged if you apply battery voltate to one and ground it.

i run 93, and make about 320 mi to a tank, then fill 14 gal...but as its my daily, i baby it

My last fill was 17.2 gallons and that the most ive ever put in it. I get about 240-260 miles per tank.
