Ok so I filled up my wifes 99 awd the other day and the thing held nearly 15 gallons. From what I understand , it should have the small tank.

Am I missing something???

She probably ran it down to the light, or just a few miles before.

On a normal fill-up (before the light), I can only fit 11-12 gallons.

Thank you sir. I always look forward to your responses.

FYI, just had to change the battery for the first time. (150K miles)

You're Welcome.

Wow, the battery lasted a long time! I believe I replaced my original battery in 09', because I didn't feel comfortable with a 9 year old battery. lol A lot depends on the climate.

I live in Indy obviously. Sunny and warm then wait 5 minutes and you will get 3 feet of snow.

I think I got a pretty good deal on the battery.

For the information of newcomers, I think it was the 2001 model year update that increased the size of the fuel tank. Mine took a little over 15 gallons today (and it was at the 1/4 level on the gauge). I have a 2002 model.

Yeah I was aware of the change in the capacity of the tanks. It just made me a little cautious that we have a mutt of a rx300.

When I get to the low gas sign on my 99 AWD, I get 14.2 gallons on a full tank.

I'm sure some here know, but probably not all, that you really shouldn't run your tank below about 1/4 before filling up. If you drive a real "oldie" with mechanical fuel pump (then why would you be on this forum ) then it probably won't make much difference, but anything with fuel injection uses an electric pump. An electric pump sits submerged in the fuel, the fuel actually passes through the motor and lubricates it and cools it. When you run the fuel to the "fuel low" warning light it is not getting the cooling it needs and probably not the lubrication either and will definitely shorten the life of the pump from what it would be if always TOTALLY submeged. My wife never lets her car get below 1/3 before filling. It's for a different reason, but I highly approve of her doing that.

I know , I know........ I will have to remind her not to let it get so low. But I need to watch how I apporach her. She is latina!!!!

I believe the 99 held 17.2 gallons.

hypervish

That's if you run it down till the last drop.
And as Code58 mentioned, that's something you should always try and avoid. It's vital for the fuel pump to have enough gas to cool itself.

Personally the most I've ever been able to get in there was 16.2 gallons, this was about 3 years ago, on a road trip from NJ to Chicago in the middle of a blizzard. I thought I wasn't going to make it to the gas station, but luckily I did. Boy, was I scared, I did not want to wait in a 10 degree F snow storm for a AAA truck to come out. lol

13.5 is the sicker capacity IIRC.

Attached the 1999 spec sheet.

I stand corrected. Thank you very much for clearing that up. Now I just realized our MPGs are HORRIBLE! O2's are now in the near future.
