Is there any difference if I fill up my car with fuel in the morning when it's cool outside and the car is not warmed up supposely to filling it up in the afternoon when its warm and the car is warmed up? BTW im getting roughly a little bit over 200 miles just a little over half a tank and I drive like a grandmother...lightly touching the gas pedal when accelerating, keeping it between 1.5-2 rpm and cruising as much as possible. Is 200 miles per 1/2 a tank bad? I say half because thats when I usually fill up my max up with fuel. I have an auto 91 se.

 

I does not matter what time of day you fill your car up. Your mpg seems to be ok.

 

amazing compared to mine...i get about 200 per TANK right now...

should i change my o2 sensor? what should i check?

 

well the car does run a richer mixture on a cold start-up, if thats what your talking about... but other then that, thats a very odd question.. lol oh yeah i mainly posted because of my sig.

 

a bad o2 sensor will cause bad gas milage...pullit out and have it ckecked

 

well i have poor mpg to thats us i use wot every chance i get

 

200m per half tank is quite good mileage imo. btw, it doesn't matter what time of day you fill up your car.

 

 

I get lousy mileags because I only have a 3-mile / minute commute to work.

 

isnt 200 horrible??? that bout be about 13 mpg give or take...when its supposed to be about 19.

 

Yes that is horrible gas mileage. Does your car run and idle good? If not your injectors might be the bad.

 

Perhaps I am dumb here, but 200miles per half tank = 400miles (640kilometers) per tank of 60 liters.

I reckon thats pretty much at best what you can expect of a 3 liter Maxima

 

Nevermind.... I thought he meant 200miles for a tankfull.

 

that's me and Tin who get 200 MPT

 

i DO mean 200 miles for a full tank...and it's definitely horrible. i just bought a new fuel filter and will install it today. we'll see from there.

 

I replaced my pasenger cv axle and I now have more of my power, and mileage. I get about 300 miles to the tank and I also get some of it back when I change my oil, align the wheels and, I'm happy to say, part of my commute incluse a 5 miles stretch of a 70 mph road, so doing 85 actually gets me better mileage.

And jsut to stir things up, I paid $1.75 a gallon for gas yesterday.

 

you got better mileage after the axle replacement?
hmm.. maybe I should fix my clickers

 

400 MPT ?? damn thats nice i get about 320 but i have a heavy foot....

 

400 per tank is very good. i'm lucky to get 300, though i drive as fast as i can as often as i can. btw, what is the top speed for a 90 gxe supposed to be?

 

128 (i think) for a 90 SE, the GXE has the same engine so it should be the same (or very close).

 

In colder weather, gasoline is denser, so you get more when you fill up. Not sure if that answered any questions, but I thought I'd throw that nugget of information out there.

 

thanks, el barto

 

doesnt the GXE only go up to 125 i've done 115 in my GXE on the highway i get about 17 mpg i think

 

just because dude's guage says half does not mean that he gets 400 miles to the tank. maybe all he does is freeway driving..who knows?/

 

Fill your car up in the morning rather than at night. You get more for your money
