Better fuel consumption on 3.2?
« on: 28 March 2013, 19:06:27 »

Hi guys, silly question :P But is there anything I can do to eke out an extra mpg or two on my 2001 3.2 v6? Apart from the obvious regular servicing and leaving it parked in the garage, lol. Are there any changes I can make? I'm a novice with the Omega's so any advice would be appreciated, thanks.

10 litres of fuel gives me about 30 miles doing school runs every day.

I'm sure someone will recommend LPG and that wouldn't be a bad idea if your using it as your main daily car. Or just buy something smaller for the daily stuff and use the Omega for long journeys , weekends, summer etc  :)

Insure that;

multi rams work.
Exhaust isn't blocked.
Cam timing is cock on.
Insure all extra weight is out of the car.
Pressures are good er ing on the high side

Lpg it.

Drive with minimal braking, ie, off the gas early and coast up to the junction etc. use the auto box minimal engine braking to your advantage.

Make the kids walk to school!

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

Good point. You do need to do the miles to warrant lpg outlay.

superunleaded.  Got me 10% more mpg in a V6 2.5 and its not 10% more expensive.

You could also try thinner oil eg 5W30.

Does sound a bit low, even without the calculation.
Definitely 10 litres of fuel, rather than £10 worth?

Good point... I always reckon on about 30p per mile on petrol from mine (and about 21p now on LPG)  :-\

Do a proper brim-to-brim calculation  ;)

It's the only way to create accurate results, and 'about' takes on a whole new level of importance when discussing mpg on Omegas  :D

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.
