try some injector cleaner... change your fuel filter and engine oil :P

if its not it could be the O2 sensor? if it is i think you should be able to smell it

last time i filled up the tank it had done just over 400km on a full tank that was around town and that wasnt hitting mivec it was changing gears about 3000rpm just doesnt seem right and that is using unleaded.

Could also be temp sensor. When they start to go it causes the motor to run rich... are you getting any pinging?

On this note could someone say how many km's from a full tank on regular unleaded one should get approx? On basis that its not thrashed.. just regular driving 3000ish rpm or less for changes.

How hard is it to change the temp sensor? And where's it at?

wait.. i thought premium unleaded was referring to stuff thats 98 OR 95 octane?

I always get 98 octane, but last time i went to a different servo and i asked the guy if the premium (it was a purple sign at shell i think) was 98 octane and he said yes.. or was he just tryin 2 brush me off and didnt no the answer :?

i get about 400km before my fuel guage reads empty, but when i fill up it only needs 45l, meaning theres still 15l left in the tank when it reads empty.
Anyone else's do this?

So i should get about 530~km out of 60l

this is driving around town mostly short trips
