Hi, I've got a MY94 imported wrx wagon, i use optimax should i be using any octane boosters with it?? My problem is that my monthly mileage has just gone up by about 400-500 miles. Due to this extra milage i may have to sell it . Can anyone suggest any ways to increase my mpg up from 20. even diving like an old man doesn't help. it automatic which doesn't help. the car is standard and i've only had it 6 months, HELP.

A big yes to the booster and a big no to the increased mpg

What boosters and how much are they.

millers octane booster is commonly used, £3 a bottle and 10 bottles in a box.

jap innovations do a box for £30 (10 in) and can post to your house for an additonal charge which is fairly priced.

hope this helps.

Try new oxygen sensors in downpipe may help your mpg.

I also found that I got better mpg with optimax + octane booster

Cheers foot tapper will try out the octane boosters and look into getting the sensor changed. Do you have any idea how much they are and if they are a pain to get hold of because its an import. I've put a block of wood under the pedal for now .
