How Good Is Your Corolla On Gas?

I filled up my car today, even though the gas guage is not working and reads below empty all the time. I had 242.8 miles on the trip meter and it took 9.55 gallons. Does that mean I get 242.8/9.55 or 25.4 miles per gallon? I guess that would be good for the way I drive, especially since it is mostly just around town and seldom on the highway? I have a 1.8L engine and I think my 1993 gets better gas mileage with the 1.6L engine, although I like the additional power that the 1994 supplies.

Does anyone know what the fuel tank capacity is for the 1993 - 1997 Corolla? I checked both manuals I have and they do not list it.

13.2 - 14 gallons depending on if you "top off" and fill up the fuel filler tube.

So if my tank holds 13.2 gallons, at 25.4 miles per gallon, 13.2 X 25.4 = I should get 335 miles per tank? I always top off the filler tube (because I don't like to frequent the gas station), so 14 gallons would yield 242.8/9.55 X 14=355.9 miles? I will have to test it to see for sure. I just filled up today so if I go an average of 14 miles per day for the 355.9 miles, it should take me 355.9/14 = 25.4 days? I guess I will repost then on 11 January plus 25 days = 36.4 - 31 days in January = 5 February? All this sound right?

Yes on paper it seems right, but there are a lot of variables. If you want to see how far you can go, I recommend carrying a gas bin filled with a couple of gallons in case you run out of gas.

That's my plan exactly. I plan to drive it until the trip meter hits 300 miles and then put a gas can with a gallon or two in it in the trunk and drive it until it runs out. That way I will know exactly how many miles I can go on a tankfull. I figure I can go about 335-355 miles.

I bought a 2006 LE in January. Initial MPG was about 31-32 with 60% city/40% hwy. After 5000 miles, I am currently getting about 33.5 MPG with the same driving conditions. I did some easy modifications though:

2) Removed secondary "air filter" in the cover of the air filter housing (improved throttle response)

4) Disabled defroster linked A/C

-For #2, I'd be weary to let more dirt in the engine over the long haul. Do you intend to replace the air filter more often to compensate?

-#4, How did you do?

#4... I also did this on my 2002 corolla. I understand that A/C helps clear fog drastically, but there are times I do not want A/C on. Using fresh air keeps the glass cleared nicely without A/C in most conditions. Anyway, I removed the HVAC controls (kind of a pain with the cables for the dampers but not too bad) and took out the plastic levers that engaged the A/C whenever you select defrost. Now, the A/C goes on whenever I press in the button, not by default with defrost. If you need more guidance, feel free to email me.

I am trying to compute my gas mileage after traveling the furthest I have ever gone on a tank of gas. Unfortunately my wife filled it up for me and neglected to write down how many gallons she put in the tank. I did get 325.6 miles before it was filled and with a 13.2 gallon tank, that works out to 325.6/13.2=24.7 miles per gallon. It was probably more like 12 gallons and that works out to 325.6/12=27.1 MPG. That is mostly highway miles at about 75-80 MPH for two hours a day.

Nooo! This is a common mistake that people make. You never fill up anywhere close to the tank capacity (13.2gal). In a Corolla, the reserve after E and even after the light comes on is about 2.5 gallons!

I would guess that you put in 10.5gal so that works out to 325.6/10.5=31mpg. Big improvement right?

I think a big cause of "my mileage is ****" complaints is that they calculated it wrong! Everyone please calculate your mileage using the actual number of gallons you pumped. You never use the specified 13.2gal anywhere in your calculations!

I got the gas slip from my wife and it turned out to be 10.988 gallons. That works out to 29.6 MPG. Better than I thought. Almost all highway miles usually around 80 MPH for an hour each way.

Does that mean you can't fill it up and drive it until empty and it won't be 13.2 Gallons? Doesn't it also burn the reserve portion when you go to totally out?

Sure you could do that, but then you'll be walking home... What I meant was you didn't actually run it dry, therefore the 13.2gal never figures in your mileage calculations. The other point is, there is more reserve than most people think. Up to 2.5gal even after the light comes on.

People can use 13.2 gallons for the tank if they carry some extra gas in the trunk and drive until they run out. It is not normally done, but it is possible.

I just love my 2001 Corolla 4-speed automatic - I get IMO very good gas mileage, I get between 30-32 mpg city driving - I've had my car almost 5 yrs and have had no problems - last fillup was 32 MPG - LOVE IT!

That mileage is very good, but at 100 miles per day, you would still have to fill up almost as much as me and I get 29.6 MPG.

I just did a test on mine, filled up, set the trip Odom to zero. Drove it 3 days to work, ran it almost to E. Filled it up with 10 gallons, got 323 miles = 32mpg. That's mostly highway at 70/75mph.
