sounds about right, flat 4 boxer is not an economical engine in any format. my mrs 2.0 sport gets similar MPG to my 2.5 hawk sti. my dads got a 4 month old XV and is lucky to get's over mid 30's per tank.
Just find a friendly MOT centre and sack off the cat's completly.
As far as the injectors just sell them, they arn't needed, unless your planning on having the engine rebuilt with forged pistons etc.
there's KYB and there's KYB.
sounds aft i know, but the standard shocks are made by KYB, but the spec on them are crap and they fail. I had KYB AGX shocks combined with eibachs on my old classic and they were very good.
Had a loan forrester for a week while mines gone in for some bits, have to saying im really liking it. it's a 2.0 so doesn't have the power obviously, but driver really nice.
Seriously got me thinking about get one as a daily.
