Mine gets around 16l per 100 too.
Adding to the above, replace your airfilter and check that your fuel pump isn't leaking.

| Post subject: | Sierra using so much fuel |
Hey I have a 1990 Suzuki Sierra 1.3L carby. And it is currently using about 16L/100kms. I was having a look at some forums and most people are getting roughly 10-12L/100kms. I redone all the carby and cleaned it out. It has 215/80 R15 tyres on it. So if anyone could help me out as to why it's using so much fuel that would be great. Cheers Grant |

Only real thing I can think of is the mixure is way too high. Does it blow back smoke when you rev it? I don't know a lot about it but that is my first thoughts. Does it have std jets in the carb? |

Sounds about wrong. Zooks will get around 10lt per 100 driving easy or hard. 16lt is way high. My sort of daily driver zook with 29" gets 300km EASY with a fill of about 30 to 32lt. |

Cheers Grant Does it leave a blacK mark below the exhaust on start up ie spits out soot ? Does it puff black smoke at idle? It could be the choke is stuck open. |

Doesnt make a difference on the driving (offroading excluded) |
