Hey people lately I have been getting crappy fuel mileage. Generally I average 430-460 miles to the tank. The past two tanks I have barely gotten 400 miles to the tank. I live in Maryland and like every where else in the mid Atlantic and Northeast it has been raining everyday for the past week. I was wondering if this could be causing it? I do not accelerate too hard, but sometimes I have too, I mean driving on the Washington beltway is like the Daytona 500 everyday. But I’m just wondering what could be causing this. I have the 02 1mzfe v6 and I run 89 octane!

Do you run the AC when it rains (like in TX, evil)?

JOSHKENNEDY · 10-14-2005, 04:09 PM

Yeah the defroster uses the AC but I was getting well over 400 miles to the tank in the summer...so I don't know

drunken_panda · 10-14-2005, 05:20 PM

How many miles are on it?

JOSHKENNEDY · 10-14-2005, 05:31 PM

59k

Could it be the Dampness of the air going into the car needs more fuel to burn with the air properly, and the ECU is adjusting for it?

JOSHKENNEDY · 10-14-2005, 05:37 PM

thats what I am thinking but I didn't know! should it make that much of a difference...Also nothing seems wrong

I have noticed a big decrease in fuel economy too, and my car is running pretty shitty. I blame it on the fuel shortage so im sure the fule comming in isent as high quality, but thats just me. Fucking oil TYCOONS!

JOSHKENNEDY · 10-14-2005, 05:41 PM

Didn't think of the fuel quality!...but I'm paying for 89 hope I'm getting 89

Try 87, and see if you get better milage,

I have a '96 1MZ and used yo put 91 in, then said to hell with it and have used 87 for 7 or so months.

Colder air requires more fuel, warmer air requires less. As the air cools, your gas mileage will go down.

Wait until NOV 1st when the oxegenated fuel hit the pumps, your mileage will go down even more.

There were points in time on my old 1995 1MZ-FE where I was getting 15-16 mpg. Usually in Jan-Feb in rush hour traffic. On the highway in the summer, the same car without any changes would get 28mpg, go figure.

You also have an intake and a high flow muffler, so colder air can pass through even easier and suck down more fuel

AIR FILTER possibly, if dirty you'll get less mileage, try replacing it, you can even slap in a k and N filter, you get better mileage outta one of those.

And whats up with "Respect Police"? they dont respect me

Most commonly overlooked when hunting poor milage is tire pressure. Make sure they are at minimum factory recommended. Pump 'em up.

drunken_panda · 10-14-2005, 08:29 PM

^^ thats true. I often lose 5-10 psi as the temp goes down. Check the air filter.
