hey guys/girls the other day i ran my tl dry just to see how many miles i get out of a full tank (300 btw) and noticed that when i put about 15 bucks in my car it reports it to be half full and thats only about 5 gallons. i know for a fact that it takes about 50 bucks to fill my car up. does this mean that i have a crappy fuel pump? what could be the cause of this error?

 

I've had cars where the first half of the fuel gauge went slow, then it dropped like a rock in the second half, and I've had cars acting the opposite way.

It's just knowing your car and how it behaves. Better to know under controlled conditions. It's not the fuel pump; it's a float in the tank.

 

 

Thanks for the info, you right, every car is different, i guess im just really paranoid because its a used car and i have no repair history on it. thanks

 

For one, you're getting horrible gas mileage. I get ~400-miles before the idiot light comes on. That's city and highway. The gas tank is 17-gallons, so you're only getting 17.6-mpg. Something is wrong.

Running your tank dry is extremely stupid and a good way to ruin your fuel pump. The pump uses fuel as a lubricant.

 

thank you for being so understanding what do you suggest i do to get better gas mileage? i see no point in saying there is a problem when you cannot provide a solution

 

Tune up, change airfilter (if it's dirty), clean the injector, and the throttle body.
Might help the gasmileage.

 

This is the first I've heard that I've been stupid for years. I always run my tank to E and fill it. No reason other than habit and laziness, but I have heard unsupported statements that by running your tank to E you are helping keep sediment from collecting in your tank.

Let me correct that. This is the first time I've heard I've been stupid for letting my tank run to E. I am married, after all.

 

Thanks, i really dont know how to cleant he throttle body, got a link to a Tut? and how much should a tune up for a 99 tl cost?

ive actually heard that before, something like its better to let small amounts of sediment go through in sections than have a huge clump fall in one day. but i guess keeping your car fueled above the halfway mark is even safer.

Use a throttle body cleaner or carburetor cleaner.
I'm always use carburetor cleaner.
"Tune up", you can do it yourself.
By some spark plug (I use NGK on 2 of my vehicles).
Summit should have it.

Running the gas to "E" it is not a good thing.
Cuz the fuel pump will suck the sand or small particles from the bottom of your gastank.

 

Well,

How many gallons is he pumping. Then you subtract that from 17 gallons. Then you can figure out how many gallons he's using to get 300 miles. I'm pretty sure he's not milking it all the way down to dry. When my gas light turns on, it's about 300 miles also. Then I put about 14.5 gallons. Which means, 300/14.5= 20.69/MPG. And I do a lot of city driving, with some highway.

You are getting great gas mileage. I wish I got that amount. And I agree, it's bad running your fuel pump to E.

 

x 2

 

well yea, i actually ran it until the "idiot" light came on and did the math for the rest, but i dont think a tune up will hurt, i have noticed that my car is starting to kind of tremble when im idling, its real Minute but i remember that i would forget it was on when i first bought it.

 

[QUOTE=Rsoetidjo]which engine do i have? 3.2L/3210cc,
3.2L/3206cc,
3.2L/3260cc???

 

Running it until the idiot light comes on and running it dry are completely different. "Running it dry" means the car stalls from lack of fuel. This will ruin the fuel pump. When the idiot light comes on, you still have 2 to 3-gallons left and is far from stalling.

And, on running the tank dry to "get rid of sediment," think of this logically: The fuel pump pickup assembly sits at the same place in the tank, regardless of the quantity of fuel. Therefore, it's going to suck in the same type and amount of sediment (if it even sucks it through the filter assembly at all) at any fuel level.

 

I can't believe I'm replying to this. S/he said, "i ran my tl dry just to see how many miles i get out of a full tank (300 btw)..." Using reading comprehension, we deduce that that the tank is full (17-gallons), and he ran it dry (0-gallons). How many gallons s/he pumps has nothing to do with it, because the tank is full and is ran dry (nothing left in the tank and the car stalled).

 

ahh, yes. I missed that. Well that would explain my explaination huh?

And yes, I can't believe you did respond, because obviously I misread it. And from my explaination, if i did read it right, it's not that crazy of an explaination.

Well, duh. That's obvious . Using some THINKING instead of reading comprehension, you will see that something is obviously wrong with his car to produce 300 miles full tank. Must not have been running it till' it stalls.

 

All tl have 3.2L.
I think the Type-S , same

 

TL 3.2L (3210cc)

 

thank you acutee, that was real helpful

 

It's a good explanation, but irrelevant to the OPs comment.

But, that's not what he said, and I'm not telepathetic.
