    Default 06 Forester 2.5 XS fuel consumption

    My wife drives a 06 Forester 2.5 XS manual. She only does town driving. Her morning route is purely stop start traffic and the afternoons is 'normal' traffic, i.e. the usual robots, stop streets, etc no freeways. She only gets about 330km on a tank (around 50L) which equates to about 13.4L/100km. The vehicle has done 106600km.

    Is this normal or does the vehicle need attention?

    I would think that's a bit on the high side, my wife's 03 Forester XT (A) gives between 12.5 - 13l/100km in town also only town driving. We get closer to 10l/100km on the road at 130km/h on the speedo (cruise control). (190000km on the clock)

    Sounds about right. My wife drove mine for a while last year and the worst she got was 13.73L/100km. She drives 5km to work and back, and only stop start not freeway. Now that I drive it to work (slightly longer distances but still in town - William Nicol) I get about 11.5L/100km average. My overall average over 18,000km is 11.10 incl long trips, towing trailer, town etc.

    Default Fuel consumption

    I drive a 2006 2.5XS Forester with 75000 km on the clock and average about 12 - 14 km stop / start a day. Never did I get less than 400 km on a tank full. The consumption is about on par with my wife's 1.6i Bantam doing about 40 km stop / start travelling daily.

    Thanks guys. I have now taken over this vehicle and driving more freeway and less stop/start so lets see what happens.

    My dad drives an 08 XS auto and he got his best consumption of 8.7L/100km the other day. I think it was 95% freeway driving though.

    I was getting mid 8's/100 driving an 07 X last year. Driving styles can lead to greater thirst...

    I have now been driving the Forester for a week! Filled up this morning as the needle was close to E. I had done 470kms and 48.1L went in the tank (stopped at the first click). This gives me a consumption of 10.2L/100km with about 75% of the kms being on freeway!

    I think the problem may have been the wifes need for speed!

    i have the same problem with my forester. i get decent consumption - close to 10 k's/l if i watch the revs. if anyone else drives and goes for it the consumption plummets.

    Just don't believe the salesman talk about the size of the reserve tank in the Forester! I drove back from Cape Town to PE, via the R62, last week end and filled up in Robertson. I drove a steady 120 - 130 on the speedo cruise and when I got to Stormsrivier bridge, the light had not come on yet, so I thought; cool, the salesman told me "150+KM on the reserve tank...blah, blah"

    Needless to say, 15 KM short of Humansdorp, on an incline, the Fozzie gave a last cough and died...SH1TE!

    R550-00 worth of tow in fees, humiliated and a fuming wife later, I finally got home!

    The Forester XT is only good for about 450KM on a tank. Do any more at your peril!

    Default Forester reserve

    As the 2002 to 2007 Foresters were mechanically very similar to the 2001 and older models - other than body panels and engine size - I assume the tank size remained the same.

    After 230,000 km, I can report that the fuel reserve lamp is EXTREMELY repeatable i.t.o. fuel left in the tank, once it comes on: 9l.

    You can therefore calculate, based on your average consumption, how far you'll get. I have driven it to within < 1l left in the tank - but then, I had made my sums correctly.

    However, twice during the lifetime of the car, one fuel brand - can't remember which - severely affected the reading - it would come on 5l early.

    I took it to the dealer to have it looked at and they reported no fault. At first I did not believe them, but 400l later, the gunk/deposit - or whatever had caused the misreading, had cleared itself, and it was as new. Still is.

    Hi Peter,

    I have the same problem, so would appreciate it if - after your investigation has been completed and you have now told your wife that she should lay off the accelerator somewhat - how it went....

    I drove from JHB to CT. Going at around the speed limit to Bloemfontein at about 130-140 with AC on I did 10.8km/l From Bloemfontein to Colesburg, driving 150-190kph with the AC on i did 9.7km/l.

    Driving around town, the car works out to about R1 a km on fuel R200 usually gives me 200-240km depending how enthusiastic my foot gets. I don't know how you guys are getting far worse consumption than I am... with 2.5 N/a models.

    I must note that my car has a sport suspension, lowering it by 50mm. Could that aid in the Fuel consumption?

    Dunno how you getting that kind of consumption. I have a 2006 auto XT. Usually do cruise control between 140 and 150. If traffic is heavy (Lots of overtaking) it drops below 8km/l. Open road I get up to 9 km/l. Swambo got 10 km/l once and she drives it like a girl. Did you check your odo against a GPS yet?

    Yes I have, its a little out due to the 18inch wheels and the 225/45/18 low profiles. But the wheels are heavier than that of the X or XT.

    Im about 5-7kpmh down at 150kph on the speedo.

    Autos are usually a little thirstier because you cant drive in vacuum so easily. (before the turbo starts spooling) They also say if you want better fuel economy and more power, you should remap it. For a little more power and even better fuel economy, fit a Vf43 from a STI. Spools a little later +- 400rpm, thus you can cruise at 120 without it running into boost. You should also make decent power after a proper tune 190-200fwkw. My Forester is only making 180kw but the power comes on very aggressively( typical prodrive map ) But its a lot of fun.

    At first my wife denied the accusation and blamed it on stop/start traffic but after a few days in her new car, a 1.3l Toyota Auris, she admitted that she missed the power of the Forester and agreed that her heavy foot was partly to blame!!!

    Just to change the topic slightly, when is the best time to check the engine oil? When the engine is hot or cold?

    Stevh0 I hear you but it is a huge difference we have in consumption. And at 150 you are sitting at 3500 rpm allready so the turbo should be fully spooled. Also my car returns the same consumption on 93 and 95 octane.

    Try some NF Street Octane booster. I get more km per tank when running it

    but saying that, the quoted figures above, I was driving on regular 95 unleaded.

    The car is just alot smoother with the NF in the tank.

    Maybe I should just take the car and tune the hell out of it. Power is not enough anymore. It is out of warrenty and service plan anyway. Bigger exhaust, maybe up the boost a bit etc.
