the first half of the full tank has more than the rest of the 1/2 tank if that makes sense.

Wasn't going to comment but how is one half of a fuel tank bigger than theother half of the same tank??

Probably the fuel filler pipe bit?

You will get more mpg out of the second half of the tank as you are not lugging around so much weight in fuel Id like to get more than 27mpg out of my 3.2

I think this will save a negligible amount, especially on a lard a**e as heavy as a mig

perceived differences in miles/half tank will probably be down to float/sender/needle calibration, and filler neck as said.

Your lucky Ive been averaging around 14 mpg around town. Ok I have a heavy foot but still think its low.

According to the readout on mine I'm getting 18.6 mpg, it's all town work though.

When I had my Omega 3.0 MV6 Auto, I was getting 16 - 17MPG, 2 mile trip to and from work. Terrible MPG considering my temporary car (Rover 400 SLDi) is doing 45MPG to and from work and 65MPG on the motorway. It runs on cooking oil, despite people scaremongering the car still runs fine on chip fat.

The best I have ever got out of the Omega was 44.8 MPG on cruise at 55MPH with correct tyre pressures, empty boot and a skinny mate.

The Rover on the motorway, well I think the fuel gauge is broke.  8-)

I similarly get about 17mpg on the run to and from work (which is why i dont use the omega anymore for that tbh!). On motorways it jumps up to about 40mpg, however.

But i had a query about this. It feels as if i have to rev the engine harder than i would expect to get her moving, which i think may be contributing to a higher mpg. It would be nice to get it to something more like 20-25mpg on local roads.

For instance, i went from Cannock to Manchester and back the other day, by the time i got off the motorway the readout read 31.7mpg but then in the 3 or 4 miles from there to home that had dropped to 30.1mpg. Significant effect then, really, given that it was a 150 mile round trip (in manchester i drove to the airport parking area and back again, so not long spent faffing around!).

Is there anything simple i can do (other than the right foot option, as im trying my hardest not to overuse the loud pedal when im driving around at low speed) that could improve the local road fuel consumption. It feels as if its a little low on power low end....

(one thing of note, when changing the cam covers a while back i noticed the connector in the plug leads had snapped off on cylinder 2. Its not misfiring, but if i tried to pull it out whilst running id get a nice little shock, which suggests it might not be the most efficient spark in the world. Could this be having an effect on mpg?)
