thats 30 bucks off fuel in todays ? Fuel gauges are rarely that accurate. so 1/4 tank may really be half a tank, on my car 3/4 of a tank is nearly full!! And remember a standard mini tank is only 25litres. I'd do a proper test. Fill up and write down speedo reading. At next fill-up note the no. of Litres and the new speedo reading and work out how many km/L. |

So if that was a 500 km round trip, I'd say pretty good. How many Kms have you travelled since filling? |

The other thing for new players is the shape of the tank. The top half holds less than the bottom half, so the needle drops quickly at first but will stay at a lower reading for longer. |

On the Asparagus Job 09, I averaged 6.5 to 7 L per 100km,s , stock 1100, 12G295 head , 1 1/2SU No7 needle , good manifold , extractors, 1 3/4 exhaust , 35 ltr tank , 10inch tyres - pressure 30psi front 27psi rear , total trip 4,410km's , so thats about 530 km's a tank overall, about 8.2 tanks, so about $373 dollars of fuel ( at average price of $1.30 a litre) , is that the sort of info your after ?

Have a look down into the filler spout with a torch, you should be able to see the actual fuel level. There is a small voltage regulator at the back of the instruments that is supposed to supply a nice steady voltage to the fuel and temp gauges. When this starts to die than you may get strange readings. |

Easiest way to tell how much you used is to fill it up again. The amount you can fit in is the amount you lost from your driving, so if you can fit in 15 litres, you've used 15 litres since you last filled up (assuming you filled al the way to the top last time). My gauge seems to be accurate, believe it or not. And the top half holding less than the bottom half makes sense - I fill up, and it usually drops to about 2/3 pretty quickly, and takes much longer to get to empty. $30 worth of fuel will get me about 300km (although the most I've ever paid when filling up is $28). I have a leyland '78 998. |

I have an 1100 out 60 thou, big cam, ported head, bigger valves, 12 inch road wheels and give it plenty and i return about 7.5 per 100km and thats spirited driving.. 
Gauge is pretty vague at the best of times.. fill it drive it, fill it again best way to get an idea of consumption |

City or suburban driving is always going to give a higher fuel use. You spend more time opening and closing the throttle and keeping up with the traffic. Highway driving with a constant throttle is a much more accurate way of measuring fuel economy. Somebody in another thread said that their 1275 was more economical than their 1100. That was exactly my experience as well. I went from an 1100 motor to a 1275 motor and saved on fuel. Simply because the 1275 motor didn't have to work as hard to keep up with traffic. Different story if your pushing either motor hard though. You can make both motors thirsty if your giving it heaps often. Mike |

so a 1275 will be more fuel economical than an 850?

Yep, that was me. I had a worked 1100 and swapped it for a standard 1275. Both motors went about the same, but the 1100 was doing it harder. The 1275 was significantly better on highway trips cruising at 100-110kmh in the Moke. Tim |

Did they both have the same ratio diff? |

In my case it was the same gearbox. Just bolted the 1275 onto it (with the obvious minor changes of course). The motor was balanced, is actually 1310, cammed and has head work, HIF44 and extractors. I expected it to use a lot more fuel but it didn't and it was just a far nicer car to drive than with the 1100 motor it previously had. I must stress though that this is normal sedate driving. Drive it hard and you can make it thirsty. Mike |
