is that 300kms taking into account of the lager tyres.
not corrected it works out to be 9l/100kms

Right, we have a Tyre Dribble Thread & this is the spot for all your Fuel Economy Dribble such as my Suzuki is only doing XXXkms to a tank, is that normal. Please state how many litres used & how many kms traveled or just use the calculator link to work out how many litres per 100kms you're doing. http://www.accommodationz.co.nz/economycalculator.html What size tyres & gearing, roof racks, extra weight etc also play a part in economy + the fact everyone has a different driving style and that each persons location differs meaning that figures are not directly comparable but can be used as a guide. The more information supplied the better the replies will be, eg are you accounting for the larger rolling diameter of bigger tyres? I'd like to keep this just for fuel mileage questions as there have been quite a few threads over the years & random question leaving specific issues & problem solving such as this one viewtopic.php?f=5&t=41250 to individual threads. Ok discuss: |

1997 SV620 LWB V6 Auto 31" MT's, 5.12's, 3" spring lift + 2" bodylift 14.1/100kms. (12 month average tyre size accounted for) over those 12 months, my fuel usage has ranged from 13.6l/100kms to 33.8l/100kms & averaged the figure above, it changes drastically depending on what i'm doing... the 33.8l/100kms was thrashing in the dunes loaded up towing my trailer, pretty much a worst case scenario. |

95 SV620 LWB 2.0V6 Manual high flow K&N style filter, 2" muffler no other mods 10L/100kms (last tank of juice before mods went on) this tank consisted of a fully loaded trip through hilly bush to go camping for 2 days, rallying through gravel rd's in 4WD racing across town at 6,000rpm (this chews the juice) and general driving. and this was using premium 95-96 octane i have just fitted 29.5" tyres and a 2.5" lift (still with stock gearing and speedo) i will moniter my fuel usage and post up an average after say 10 tanks of juice |

Sierra G13BA 2in lift Roof racks 235/75r15 tires Standard gearing. 95 octane Getting around 9L per 100k highway driving, 4th gear 3500rpm cruising at 90. That goes up to 11L per 100k in low range stuff. Not bad for car with 280,000ks on the clock. |

I have a 91 sierra hardtop. With a great condition g16b which is a jap import model. I get almost 300kms if I drive conservatively. I always use shell v power as I find the engine runs a dickload better plus I get better economy. I have no gearing and 30x9.5 maxxis bighorns. Plus my rear space in the hardtop is chocked full of tools. I filled up on near empty and its about 33litres. I have a surge tank with twin pump setup. |

I put the worksite into google maps and then timed the distance by 2 then that by 5 for the working week. That alone is 230kms. Then on the weekend I'd roughly do about 50-60kms in it. |

I'm a plus 1 for v power. I use to fill up at freedom fuels and the car wouldn't idle the best and lacked low down oomph. There's a noticeable difference in running/idling and also a noticeable increase in low down acceleration. |

I get BP Ultimate if I can. Dont really notice anything other than better idling and it makes me feel like im looking after the car a bit more by using premium haha. |

Using 98 will be better for your power train, but unless you tune it for the slower burning fuel, you will not see a big gain, tune it, much better. |

1981 1l Sierra 30" KM2s Wannabee exocage thingy. Seemed to have bigger carby jets, had a mildly blown head gasket. 16l/100kms on highways. 1980 LJ80v 25" H/T tyres Had roof racks but didn't seem to make a difference when I took them off. Really worn out/neglected motor. 10-11/100 for general country driving. |

There's not a big gain, but for the extra 20c a litre it's well worth it! |

Can someone show a simple/easy way to work out, litres per 100kms ?

first post has a link to a calculator, pump in your kms traveled & fuel usage & it will give you the answer. |

Its really simple, your kilometers, divided by the fuel used. 300kilometers 28liters = 300/28 =10.71kilometers per liter If you do it the other way round, 28 liters 300 kilometers =28/300*100 = 9.33333 liters per 100k |

my lil airport car, dead stock JLX vitara, except for bigger coil and tuned for 98. when I got it, was on 91, couldn't get less than 10, mostly about 10.5 liters per hundred, now, on 98, (about 2 years worth) I do my calcs on 8 liters per hundred IMO a lot of diff, 98 does not cost 22% more, cheaper to use the better fuel. |

since owning the blagon i think i've only put 1/2 a tank of regular unleaded (91) mixed with 98 through it so haven't really got a good test base. as SierraDan said earlier i feel better knowing i'm putting the good stuff in it seeing i do give it a fair bit of curry 99% of the time. |

This is one big reason i switched to 95+, 91 contains much more Sulphur, and i have seen what Sulphur does inside a fire tube boiler, that i had to clean out, and i definitely dont want that crap in my engine...

Smoother fuel, close to zero chance of pinging, so, far better for interbnals, or, power train. I thought cetane was a diesel thing, not petrol ? |
