Is 100 miles from £10 of petrol reasonable?

Thanks for that. I thought that I might have a 'too rich mixture' situation (whatever that is) on my hands... in which case, I guess it's a garage job.

You won't have 'too rich a mixture' on your car,as the mixture can't be altered as it runs on fuel injection,and not a carburettor.

Looking at the figures, I don't think you've got a great deal to worry about. Both cars seem to be in a fairly normal range.

There is some truth in small engines having to work harder, but that's not always the case. However, there's a lot of truth in the Renault being light - it weighs in at just over 1 tonne, which is about the same as your Corsa. Surprisingly, the drag coefficient on the 19 actually is better than the Corsa, though only slightly.

Overall, 36mpg isn't too bad. I'd love to get even close to that, but 25mpg is an achievement for me, but then I don't drive a sensible car.

How could I have been SO foolish? There I was thinking that, since the Renault LOOKS twice the size, SEEMS to have a bigger engine, APPEARS definitely less sleek and the reg. doc. CLAIMS it's 6 years older, it might just be less fuel efficient than the Corsa rather than vice versa.

It DOES have a bigger engine, no illusion there.

Old engines can be more fuel efficient too. They loosen up as they wear. Ultimately they become less efficient once the piston rings wear and they lose compression.I've seen loads of oil burning engines pump out good power.

Small engines like 1.0 or 1.1 are great round town but are usually geared for this sort of thing, so you end up working them hard on the motorway.

How are you measuring the miles per £10?

There are other factors to consider regarding fuel consumption,that are sometimes never thought of,like driving with the windows open,or having the air-con on all the time.They can make a difference.

My car has a computer facility to show mpg as you are driving,its amazing what difference driving style makes and frightening how much fuel is used when the engine is cold.

its a vauxhall that about right. My mk4 astra 1.6 16v will do 80 - 100 miles to £10 if i drive carefull. if i put my foot down i get much less. I know loads of people with vauxhalls as im a member of mig web a vauxhall owners website. Im sure they asked the question on there and everyone had about the same.

Do you do shorter trips - my trip computer tells me I get about 43 on average (brim to brim cals put it at 46 but close enough) but instant consumption before the engine warms up is below twenty (ouch) - similary wife who does short trips only gets about 25 - then again I only get 25 in her car on long trips but that is a different story officer...

pavlovs_dog

is there a site anywhere that tells you what the average MPG is for each type of car?

I have a 1995 2.8 TD LWB Shogun and to £10 of Diesel I am getting under 20 (TWENTY) miles.

I have recently serviced the vehicle... and have not noticed a change.

I know of a fault it has an slight oil leak from the sump seal. Would a slight leak affect the ammount of miles I get out ot my vehicle?

other than the oil leak where do I look next TURBO, FUEL PUMP, MIXTURES?

tomstickland

Oil loss would not affect mph.
2.8 Shogun is never going to manage good mpg, but I'd expect it to do 25mpg on Diesel.
Must be something seriouslly wrong for it to be that bad.

Didn't you say you were making over £150 per day from RISK FREE methods though?
