Fuel economy

[Afrikano]

Hey, this is my first post, but i have been on this site for a while. I bought my first car ( which is a bloody buety) its a 2002 Vy Ute with full SS body kit, 17" but hasnt been lowered, im planning on using the car for a few work related things so i dont wanto lower it. Yer that pretty much the car but my Question, it has a sports exaust and i cat...now i dont know much about this stuff so hopefully i said the right thing there. But does having the exaust and cat use more fuel? If so is it a major percentage difference or nothing to really care about? Because the car is alsp running on lpg..so with duel fuel itll be better, currently its at 15.2L/100km..to me thats a bit high?? Cheers

it depends on your driving alot if you drive like a grandma then you should get 500+kms out of a tank n o problem but if you dont the you give it a bit of peddel then expect the ecomomy to be around 350-450kms per tank

Is it a V8 or V6? 15L/100k's is a lot for a V6. There's something wrong.

My SS is sitting on 12.9ltr/100km with an average speed of 40.8km/h

Oh yes another thing, it got a full tank now and shows 330km to the tank..now my mates Vy SS wagon shows that..and i drive nothing like he does (kinda explains hes balled tires lol)

there would be a faulty sencor me thinks most probaly the oxy

 

[Afrikano]

Oh so nothing to worry about..see i come from a family of Toyota lovers, im the first Commodore and first V6..every little chance they get they will gimmie the shits lol

Actually there is something to worry about. If it is a faulty oxy sensor it will be causing excessive fuel comsuption. Before you go replacing them, change the oil, and replace the plugs, leads and air filter. Also run a bottle of injector cleaner with the next tank of fuel. Get a can of "maf cleaner" from supercheap and pull out the maf sensor and spray all the crap out. All these things you should do when you buy a car, reguardless of your fuel issue. If the fuel issue still exists after this then replace the oxy sensors.
