    2002 Vy Ute
    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.

    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.

    oxygenb sensors have a service life
    THEY DONT LAST FOREVER
    heated o2 sensors (IN YOUR CAR) last 160,000km's aprrox

    but it sounds like you just need a good tune up you know? plugs air filter fuel filter then check it again after resettting it in your mode set instrument menu!~

    Oh ok, cheers mate, i gave the car to my mechainic so hes done some checks himself, pretty sure he changed the plugs but ill double check with him. Ill be sure to do all the things you mentioned. And how do you pull out the maf sensor? Im guessing there will be instructions on the can?

    It depends on your drivind and if you have dual fuel is the 15L on petrol or gas.

    On a trip i can get my VY manual JUST into the 7L/100 (my car has most if not all the bolt on bits) but if im just doing city driving or trips around my local area it will get over 15L easy

    When I'm lapping about in the city I can see as high as 16L/100km. Country roads i get 6.5-7.5L/100km pretty easy.
