My 4.2 seems not too bad on fuel consumption on a long journey but when starting and stopping it often i am sure i can physically see that the fuel gauge needle has moved a fair distance on every new restart of the engine. its like it is using a gallon of petrol just to start the blinking thing. i am considering leaving it running in the office car park whilst i do a days work in the vain attempt to save some fuel. I appreciate the fact that cars use a fair bit of fuel on start up but this seems excessive. anyone else have this problem?

Yep, short journeys mean I average 14-16 mpg. Can get 22 mpg on a run.

A mate of mine came with me to the Ace Cafe last week. When I pointed out how much fuel I'd used on the journey there, he said "The way the needle was moving, I thought that was the Rev counter!!"

Its only money, and a lot of the Tesco 99 i put in gets burnt after it leaves the exhaust too

I have a 2003 4.5. Around town I get 140 miles to a full tank of gas, that's 140 miles for about 14 gallons (10mpg). On a good run, mainly motorway, I get 320-340 mile to a tank (3000rpm in 5th 90mph), about 24mpg. The least I've ever got from a full tank is 108miles but that was in Germany, say no more.

Regards
Simon.

Is your gearing or final drive different to mine then? My '98 4.2 is 25mph/1000rpm in 5th.

Middle teens normally but once, whilst calming the Mrs' enraged spirit , I actually achieved 39 mpg


.... but, then again, I was on the back of a Tow Truck

My boot seems to permanently smell of petrol which would confirm "The more you use it, The More you Save" theory - perhaps we ahould just register it as a new cocktail called the 'Molotiv' !

Simon's is a 4.5, I'm not sure if that makes a difference or not.

My 4.2 is, 1st gear 7mph, then, 11, 15, 21, 27

Ours (late '97 4.2) averages about 18/19 on a tank. The best was 24 with a fair amount of easy(ish) motorway driving.....
