hey guys i got a 86 camaro with the 305 motor, i am getting horrible gas mileage , anybody kno the what the symptomes could be its sumthing around 200 km to an empty tank

 

R u fuel injected or carbed? Has the car sat for any prolonged length of time? Have u done a full tune up... plugs, wires, fuel filter, cap, rotor? R ur plugs properly gapped, is ur timing correct? Make sure ur brakes are not binding against the rotor when not in use. When was the last time the injectors were cleaned or flow tested? Tire inflation? Alignment? there are plenty of factors... What r ur driving habits like? do a lil research and let me know....

 

well the car is fuel injected, i recently got a tune up , oil change and filter , plugs and wires , i use only put 91 in it , um i cruise the thing but sometimes i push the thing, i got fuel injector service just recently too, but still i think something is wrong for only getting 200 km to a tank

 

Like I said there will be a lot of factors that will affect gas mileage. But these cars arent exactly gas savers either.

 

ya i know that these cars guzzle gas but i was expecting way more gas mileage than that, i think im going to go to a place where they can hook up a computer diagnostic thing and detect what could be wrong?

 

good idea, let me know what they come up with.

 

Were you getting poor fuel economy before the tune-up?

These cars aren't "gas guzzlers". You should be getting a lot more out of a tank than that (how much do you put in when you add fuel after the tank is "empty"?).

 

How are your driving habits? Are you driving like an old lady, or stomping on it getting ahead of everyone from every stop light? Hows the alignment? All tires aired up properly?

Also there's no reason to run 91 in your car, you can get away with 87 or 89 octane just fine.
