Last night i ran a little test with a theroy i had, that the TL when extremely low on gas, compensates by dropping engine power to use less gas...

I ran the tank down to almost nothing, a little bit below the "E", had about 2 gallons left in it... The car seemed all of a sudden slower at somepoint... i could tell for sure because the torque steer in the wheel was almost non existant, then i filled up, and took off, and of cource i could feel a difference, she was definatly moving faster, and the torque steer was what it usually is...

You guys ever notice this?

 

I never noticed that happen to me. The most gas I've ever used up without refilling was 16 gallons. I really didn't notice the car behave any different. But then I wasn't racing the engine, because at that point I was just trying to conserve gas until I got a chance to refuel.

 

isnt our tank 16 gal?

 

I believe its 17 gallons and some change...

 

Its 17 gallons... The lines, filter, filler neck account for the change

 

At what point does it go empty? I've ran it down to the bottom line before but haven't been brave enough to see how low it can go.

And considering I'm now paying $1.70+ for gas, it's going to be low a lot now.

 

well, since gas weighs 6.? lbs per gallon, 6 X 17 = 102. when you have a full tank of gas its like adding another passanger so of course the car will feel faster when you are low on gas because loss of weight

also, i thought we had an 18 gallon tank

 

When the light comes on I have about 4 gallons left. I usually go another 50 miles or so before I fill up. I'm not too eager to pay $1.83/gallon all that often.

ummm read his post again..he's saying the exact opposite thing. The TL compensates for having a low load of gas by reducing engine output thereby being slower but increasing fuel efficiency. When the gas tank is full, the engine returns to normal operating power..at least thats what the originator of this post is saying

 

wtf you beeen smoking lately!

 

he always been smokin'

Zing!

lol o my bad

 

One possibility is that running on a low tank somehow lowers fuel pressure (sucking air or hot fuel pump not working as efficiently). The reason I say that is that some mods involve increasing fuel pressure for increased HP.

 

I don't understand. What is so hard about looking up the info in the manual or the Acura website? Only noobs guess...NONE of you guys should, especially about something as simple as this.

Fuel Tank Capacity

17.2 U.S. gallons (65.0 liters)

BTW...the most I've ever filled up was around 16 gallons.

 

exactly how much do we have left once the light comes on? I always thought 3 gallons or around 60 miles. Just wondering if anyone knows the exact amount.

 

I usually don't chance it with my gas gauge. My gauge only goes up about 7/8 of the way up even when the tank is filled to the tippy top.

 

Take it to the bottom and run the risk of having fuel deposits clog your filter and overcome it... Never let it go under .25 tank... just my 2 cents worth.

 

Fluid Dynamics guys.

More fuel equals more "head". In other words the more fuel is in the tank, the more the fuel is pushed into the fuel lines, therfore allowing the fuel pump to act more efficiently in delivering gas to the fuel injectors.

The lower your fuel level, the lighter the car, yet the car has a problem delivering the gas to the engine.

Using the concept of fluid dynamics to get ther most fuel efficiency out of your car, you should fill up your car when it reaches a half tank. By following this rule, I get approximately 27 - 32 miles a gallon from my TL-S (mostly highway).

You car is most inefficient right after filling up (to about 3/4 tank) and when nearing empty (about 1/4 tank left).

 

Fluid Dynamics sound good to me, I am going to try this experiment with my car.

I have been filling up my tank when the light comes on, I have kept track of the milage and it is at around 24-26 mpg (mostly highway miles with a little traffic driving ).

Half tank of gas is usually at around 160 miles on the average.

My tank is at the halfway point and I am going to fill up a little after half and keep track of the mileage...

I will keep track and let everyone know what I find out.

 

There are other reasons why the light comes on with 3-4 gallons remaining beyond the ones mentioned above.

1) You never want to suck air with your fuel pump - it's hard on the pump and seals. It's like running a pressure washer without a hose attached - you burn the pump.

2) The fuel in the tank cools the pump. I've heard that constantly running your car bone dry will shorten your fuel pump life and they ain't cheap.
