Thanks guys, the way I have been measuring is as soon as the fuel light comes on I set the trip meter to zero and put in 10 litres (not £10), then drive until the fuel light comes on again, I did this religiously for 2 weeks and it always measured in at 30 to 32 miles before the fuel light came on again.

Fair enough. I wouldn't put too much faith in the light, but your results are certainly consistent.
At a tenner, I would have said it was about right, but with another third on top I would expect a bit more  :(

if its auto, convert to manual.. if most of your commute is urban your consumption will drop.. there are some mechanics here who converts them..

What are you currently getting out of it?
10 litres of fuel gives me about 30 miles doing school runs every day.

That equates to 13.6 MPG,  that cant be right :-\


I'm getting about 25 miles to a tenner (17mpg ish) with mine and I don't mess about  ;)
Check the multirams ect imo  :)

This thread is making my eyes water  :o

100 miles costs me around £12, £14 if town work, with summer tyres on (uh-oh!) got around 412 miles to a tank (74L/£50) of gas.

Tell me about it  ::)

I finished the back end of the lpg conversion 3 weeks ago but due to wind / rain / snow / taxi service for the missus or my own work, its gone no further  :'(
What i'd do for a garage to work in. All my work is carried out on the road outside my house  :(

Anyway, enough moaning, the sun is out  :-X so I've got a gearbox oil filter clean / flush and a selector to abuse clean and setup  :)

Not sure LPG is the answer here, as guessing all short journeys?

+1.  :y Much better on all fronts as far as I can see .............

Is there an idiots guide to what these "multiram" things are and how do I check if it's working ok? I've done a search but can't really find anything that explains what they are and what they do and how to check them? Thanks guys.

I'm doing much better than that....mine does about 15 miles to a tenner!!  :'(

What do you think of these http://engineheaters.co.uk/ ? Only £50 for a 2.6/3.2

I found this after wanting to make my own way that pre-heated my engine to save a lot of fuel and reduce engine damage. Not a new idea in itself I know but was googling after designing some things and trying to find a way of using the electric pumps connected to our cooling systems and discovered this.

They seem to make sense and could save me £30/week if they do as they say on the tin. The company told me that the oil never gets baked on to the sump. The only problem is miggies are quite low and we have rather a lot of speed humps on our roads so they could get scrapped off.

Could even put one on the gearbox sump.

I'm also looking at ways to pre-heat the air intake between the air filter and MAF so the ECU is "tricked" in to reducing the fuel injected.

Any thoughts? Just don't shoot the messenger  :)

122 miles from the last £40 (£1.37). Driven gently due to suspension issue, but biggest culprits have to be a failed thermostat and low ambient temperatures :-\ between -3° and +4° lately.

In that case get yourself a little 1.2 LPG run around and the Kids can run behind you. :y
