MG MGB Technical - mpg

just working out my fuel ecnomy,my car does just over 50 miles on ten pounds can any one work out what its doing to a gallon. is that heavy on fuel thanks

The manual states that a MGB will do around 22mpg I take it that you mean 10uk pounds so it sounds about right
John

assuming 95p per litre for fuel its about 10.5 litres or 2.3 gallons

50 / 2.3 = 21.7 mpg

Not bad really, the everage should be around 25mpg for mixed driving. On motorways with overdrive you can see figures of about 35mpg or more. Last time I checked mine it was about 23 mpg.
andrew.horrocks

thanks for that may be im useing a little more due to the fast road head and piper 285 cam k a n air filters and 4 branch man giveing ma a tad under 100bhp at the wheels

A Plumber eh? I thought simple maths and working out volume and flow rates would be an essential of the job?

My '67 BGT did about 7.8 l/100km (about 36 miles/gallon) from Cambridge, Ontario, to Madison, Wisonsin and back. About half on interstates, some on nice paved state roads in Michigan, some crawling along near Chicago. That's real gallons, by the way, not the piddly little US ones. Would still be about 30 miles/gal US.
Mostly at or just under the speed limits.

What is the price of petrol in the UK these days?? The exchange rate is still around $1.75 / 1 BPS. There are 3.8 litres = one US gallon

Where we are in Essex Co. NY the price of one US gallon of petrol is $2.75.

Although no-one is going to worry about mpg on US fuel prices - It's worth measuring MPG as an indication of the state of the machinery - not just the engine - mine gives 28 at an average 60mph - 23 at an average 95mph - (British miles and gallons) - proving also that the weight of the boot is critical - and the V8 is more economic at 95 than the 1800.

We're at about 93p/litre or just over $6/US gallon Gary.

we pay to much tax here but we benafit from a free health care we have a minimum wage pensions good unemployment benefits the list goes on

I'm taking note of RMW's comment: "...no-one is going to worry about mpg on US fuel prices..." Granted, we Americans are spoiled in this regard, but as fuel prices head toward $3/gallon over here, we are starting to sit up and take notice. And well we should! We've allowed our public transportation systems to fall into frightening neglect, while indulging in suburban sprawl that results in a lot of Americans spending 2-4 hours per day in their cars just getting to and from work. Until we revitalize our inner cities and rebuild our railroads, even at half the prices paid in the UK and Europe, we're going to continue to spend more - maybe twice as much - per capita for fuel. 'Tis a problem of our own making. No sympathy desired or deserved. But the lifestyle we've inflicted on ourselves does raise some concerns at $3/gallon and fuel-efficient cars are starting to pick up again over here. My B/GT consistantly gets 23/33 (urban/rural) and that's just one more reason for driving it daily in place of my Dodge truck which I wouldn't own at all except sometimes I have to pull an MG on a trailer (no, not to shows!).

why are you still driving very larg engine cars i have a deisel car which as 130bhp and touches 70 to a gallon and does 115 mph
daz

Hey daz, we're talking about America; "bigger is always better", right? (Please don't shoot the messenger.) I only said "...fuel-efficient cars are starting to pick up again over here." And it is true that Toyota dealers can't keep Priuses in the showrooms. Further, it looks like "minicars" were rather a hit recently at the NY Auto Show. I don't know why diesels haven't caught on here like they have over there. Is your diesel car available here? If it is, I'd like to buy one. What's more, that diesel will run on used vegetable oil from MacDonalds. 70 mpg on diesel makes the whole hybrid technology thing seem rather silly to me.

Don't ask me to justify the large engine cars. I can't and I don't care to. I may be American but that doesn't mean I endorse all that goes on around here. Indeed, I'd like to ask the same question you ask. But maybe the large SUVs getting 9 mpg are just another reason why Americans are starting to get upset as fuel prices approach half of what you pay. Hopefully, they'll figure out that the only solution is to lose the 7-liter SUVs.

FWIW,

Daz, I just read the thread a little more carefully and note your comment about your taxes are too high but you get free health care, minimum wage pensions, good unemployment benefits, and "the list goes on." Maybe if we had those benefits, we wouldn't be complaining so much about $3/gallon! Maybe if we taxed the fuel up to $6/gallon, we could afford these basic necessities. The working middle class is drying up over here. Our elected officials are so indebted to special interests that fund their election campaigns that they can't voice any real opinions or make any constructive compromises. They sure don't do anything for what used to be the great American middle class.

I suppose it's too late to ask you guys to take us back...

cooking oil can be used but you must send money to the tax office on every liter used. the oil needs to be thined down or you can buy a unit in america which thins the oil down ,it an electrical element and includes a filter. i have a people carrier citron picasso on the computer it averaged 76 mpg on a run and 50 in town. the trouble is the goverment have made deisel more expensive than petrol in the uk yet costs one quarter to ptoduce ,its only a thin oil not as refined as pertrol thanks daz

Steve Postins, et al: your 93p / litre works out to 3.8 litre to one US gallon. The current exchange rate as of Wed was $1.785 to 1 Bps. So the math works out like this .93 x 3.8 x 1.785 = $3.55 per US gallon. Today regular grade petrol cost me $2.89 / gallon. Good thing the MGB is economical on fuel

I just rechecked my figures. I have a dodgy calculator. The math works out .93p x 3.8 x 1.785 = $6.31 / US gallon of petrol. Right now Americans are paying about 1/2 that for a gallon of fuel. Historically fuel prices jump greatly about every ten years. America has been an oil based economy for decades and is not about to change soon.

Big George W is sure not going to take care of us,cause he spend all our $$$on the war!!!!!Just my 1 bit....

Rich,

I'm with you! Here's "W" threatening to prosecute price gougers in the oil industry. Fox guarding the hen house?

Allen,
Sorry for you but since the '70's "small is STILL beautiful". Ask the unix community versus the Windows mouse guys!
Renou

Renou,

I hope my attempt at satire was clear enough that you understand where I stand. There are a lot of us in America that are repulsed by the "bigger is better" cowboy mentality currently running this country. We are a nation of limited means and huge domestic priorities that are being ignored. Arrogance is not a solution. But "small" and "modest" are part of it. Hey, that's why I drive my MGB! A little humility in dealing with our allies would probably help the world along a bit.

But I fear our political system has been bought out by special interests, and elected officials whose campaigns are bought by the special interests are hardly in a position to install campaign reforms that will cut off their own support.

FWIW, Allen

I just got back from the Las Cruces, New Mexico British Car days event. Great event. The trip was from north of Denver to Las Cruces, New Mexico. 1500 actual miles round trip. There is a significant change of elevation about every 100mi. with a peak of 7600 to a minimum of 4000. We had lots of head winds and tail winds.

Speed was mostly from 70-80mph. Primarily interstate highway but some back roads and a driving event. Car has OD.

Tank to tank mileage varied from 22mpg to 36 mpg. Overall average came in at 29.8mpg (US gallon)
