Fuel consumption.

[ph1l5]

Hello. Can I check with others on fuel consumption. I fill up £30 of petrol but it seems to go rather quickly I used 1/4 of a tank yesterday and I went about 30 miles. Being aware of the fact that there might be an issue I did drive at a steady 70 on the M40. What are other peoples fuel consumption like ? I went out with TVRJock a few weeks ago and after a couple of hours I was almost empty and he hadnt seemed to use anything ?

Cheers Chaps

Hi Phil.

My Chim 4.0 does around 25-28 on a run at about 70 -80 around the M25. 24 ish around town or country roads with a heavier right foot.
I dont often drive in heavy traffic

I always get at least 200 miles per fill up .

Using the gauge of to measure what your've used is probably not the most accurate method of acessing MPG.

I mostly use Tesco's Super High Octane whick may also affect MPG.

Yep 200 miles a fill up is normal for every day around town/spirited driving. Will normall get nearer 300+ on a motorway run.

Mine only gets around 150-160 miles between fill ups (hence my thread a few days ago wondering about fuel consumption)

Granted it is used around town mostly, but even driving around carefully / doing half motorway journeys i can't get above 17mpg.

Im going to do some engine diagnostics soon though as it appears to be running very rich and is not as smooth as it should be.

......or 6.5 mpg on tracks days. That's a full tank in a morning session at Castle Coombe !!

Hope that helps

Been checking mine recently 1998 450 provides 18mpg across country over two days, or constant use at 90 megatrons on the Mway gave me 23mpg. Thought that was good

[over_the_hill]

98 Chim. 4.0
According to the handbook the tank is 57 litres (12.5 gals)

Steady Motorway with light right foot 25mpg (possibly a bit better)
Mixed roads 20-22mpg
Commute (rarely out of or above 2nd gear) about 14/15mpg

So on just commuting three gallons which probably looks like a quarter tank via the gauge is about 40-45 miles.

I get 18mpg around town, on trip down to Le Mans this year I was getting around 23 out of my 4.0HC Chim.

Hi Phil
Have been up in Jockland as you know. Mmanaged 33MPG on the way back and was not hanging around (under 5 hours), but i have replaced Lambadas, afm and the ignition system ie plugs out to coil and what a differance it makes to mpg.
See you Sunday

2 questions:
Did he have a piece of rubber tubing with him?
Did you leave him alone with your car at all?
Hope this helps!

Average around 25mpg, combined driving of light in town and heavy booted in the countryside.

If I stick £20 in, I'd expect to see 80-100 miles out of it. Only over put £30 max in it and got 160. Never filled it up before, I'd be less careful with the fuel if I had more left!

I have a 1998 450 that is my daily car. I get between 17 and 22mpg depending on how i drive it. Usually get 200 miles from a full tank.

Me too, exactly the same

With my Griff 500 I've seen a range of 13-24 mpg

Same for me.

I never take it particularly slowly, so prob don't get as good as I could, but if I wnated to accelerate slowly and save fuel I'd drive something else. My long term average (in a 450) over 3.5k miles over the summer was about 19mpg, but on motor way stretches I think I prob get around 24. I don't think high 20s in mine is possble, unless it's on the back of a trailer that is...
