Low gas mileage on Subaru Outback 2003

I only seem to be getting around 14-15 mph in my Outback. Info tells me that it should be 18-21 city. I'm wondering what could be wrong. I have about 80,000 miles on the car.

Sometimes a bad engine temp sensor (not the coolant gauge sender) will cause the ECU to stay in 'choke' mode.

Could be a clogged air filter, faulty air flow sensor, or faulty oxygen sensor. All are common reasons for poor mileage.

Can a 2001 Subaru Outback take an aftermarket stock clutch or do you have to go with a Subaru clutch only? fighting clutch chatter two clutches in two months after orignal clutch lasted 130k miles?


Get a new clutch kit AND flywheel. Don't turn a flywheel more than once, just like with brake rotors. Any car can use an aftermarket clutch replacement (as long as they fit, of course). If you get a lightened flywheel, you'll enjoy better acceleration and mileage (city driving) as well.

I have a 2003 outback we put a scanner on the car and drove the car at 45 mph the front o2 sensor was reading 5.5 the rear o2 sensor was reading 0.07 my gas mileage has dropped there are no codes showing...


If no codes are showing up, but you're fuel mileage has decreased, make note as to where you are getting your fuel. Differently fuel doesn't make a huge difference, but when I worked at a gas station, I had employees from the gas station next to us telling me that our fuel gave them better performance and mileage than theirs did - also, make sure that you're air filter, filter for turbo (if equipped) are new, and you may wanna check your spark plugs, to ensure they are gapped correctly. Another thing to consider is the catalytic converter being plugged, or the muffler even.
Let me know if you have further questions,

Hello,i bought a subaru outback 2002 from 3 months.and it's consuming more gas than normal.(130km/20 litre) could you please tell me what i have to change? and what is the normal consumption for this...


REPLACE AIR FILTER.CLEAN FUEL INJECTORS,CHECK TIRE PRESSURE.LOW TIRE PRESSURE WILL CAUSE LOT OF FUEL CONSUMPTION.CITY DRIVING WILL BURN LOT MORE GAS,STOPPING VECHICLE THEN GOING WILL CAUSE MORE GAS BURNING, YOU NEED POWER AND FUEL TO GET VECHICLE IN MOTION,BY IT BEING HOT WEATHER, USING AIR CONDITIONING TO KEEP COOL INSIDE WILL CAUSE MORE FUEL CONSUMPTION.

My `1997 Subaru legacy outback wagon ,my gas mileage went from 21 MPH to 15 MPH. What do you think is wrong.


if there are no major problems present all it needs is a tune up(spark plugs,fule filter,oil change, air filter, fule injector cleaner). for a upgrade in fuel economy add a short ram intake, parts are fairly easy to install.

I think your (and my) Outback uses gas-filled shocks so the tell-tale signs of leakng fluid will not be visible.
Oddly, Haynes doesn't mention which is standard.

Try the 'bounce test,' it isn't conclusive but it may give you a clue as to whether you have a blown shock or not.

Push down firmly on each fender individually and let it rise suddenly.
Note how each corner responds, if a corner rises a little above static level, then falls back and stops, the shock is probably still functional.
If one or the other seems to bounce a little more than described, the shock is probably toast.
They should always be replaced in pairs.

120 K is a good run for any shocks; they mostly start to lose their function at half that mileage.
