1.8L FWD Auto Impreza - normal gas mileage?


Recommended Posts

Mine gets right around the 30 mpg mark, mixed country road/ 2 lane highway/ town. And thats with almost 200k miles on the clock. I've seen 2.2's get around 18-20 in town, but the ej18 should pull better than that, especially being FWD. Somethin's up. Might just need a basic tune up or O2 sensor could be getting lazy. Any dead bodies in the trunk?:grin:

 

Just to make sure...you're not going by the gas guage are you? 'Cuz mine reads on a quarter when I've really got a half tank.:rolleyes:

It doesn't have a low fuel light, and Jessica fills it when it gets down close to E, usually takes 8-9 gallons to fill it from E, but I have no idea how big the gas tank is. I think I'm gonna run down to the parts store and pick up a set of plugs, wires, and an O2 sensor and see if it helps.

my 1.8 impreza's were always horrible on gas. :-\

 

I've has an OBS with a 1.8 AWD 5 speed that could on a good day on the highway only get 24-25

 

The guy who does my inspections told me of a custome of his that has a 2wd that gets 32-35 but i didn't know if it was 5 speed of not and I'm sure that is driving like grandma would drive... :rolleyes:

 

 

I think your issue is the fact that it is automatic....I think that is hurting you mostly.

My '93 FWD has a 15.9 gallon tank. I think the FWD's had 15.9. AWD's were 12.9? Not sure on the numbers, but the AWD tank is smaller to accomodate the rear diff and whatnot.

 

Anyway...8-9 gallons when close to E...that gauge is way off. It takes mine 7-8 to fill up when on 1/4, so my gauge is reading 1/4 under. Sounds like yours is reading 1/2 under. These gauges are pitiful. I just fill up when close to E, knowing that I've got about 1/4 tank left.

 

I manage to get 28-30, mostly highway, and I don't drive like a grandma. Never done anything but oil changes since I got the car 3 years ago, so I'm sure it's in need of a tune up. New plugs and wires are in order, but meh...i'm lazy. Will get around to it eventually.

GET WITH THE PROGRAM HERE!!!!!!!!! WE ARE TALKING ABOUT AN IMPREZA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

 

I just looked in my 1995 impreza owners manual... it doesn't say there is a difference in tanks but it says the tank is 13.2 :headbang:

my 1993 impreza owner's manual lists the fuel tank capacity as 15.9 US gal (13.2 imperial gal) but that aint what the pump be sayin'

I'm telling ya...a 95 impreza is rated at 13.2 us gal/50liter/11.0Imp gal plus the fact that I owned a 95 OBS and a 95 L coupe. It really is that small of a tank.

 

I seem to remember a long term test in Car and Driver where their's said it had a 15.9. It wasn't until they ran out of gas that they realized it was an error. I wonder if I can find that magazine still.
