Just a dumb question maybe, but is there more than one definition of a gallon  ? here: http://www.wolframalpha.com/input/?i=11+gallons+in+litersthey say 11 gallons are roughly 42 liters. Which also roughly matches the fuel capacity of the 2009 two-seater. My max fill-up was 41 liters, and the needle was not completely down to zero yet. However, the Company in their advertising material of 2008 says that the fuel capacity of the Plus 4 is "55/12 (ltrs/galls)".  While I have the paperwork  here: the Plus 4 drive ratio in fifth gear is 0.76 and the axle ratio is 3.73. That yields 25.1 mph per 1000 prm (if you believe in their numbers). Andy

Andy,
Don't know if this helps but when UK sources talk about gallons, ' gallons' is short hand for the grandly named 'imperial gallons'. There is also the US gallon which is a lesser unit, so different info might depend on the source of the website.
As a guide, 11 imperial gallons is equal to 13.21 US gallons; 11 imperial gallons is equal to 50.01 litres 11 US gallons is equal to 41.64 litres

I got the original owners' handbook when I bought my 2000 4/4. That states the fuel tank capapcity as 11 Gallons/ 55 litres.
I also have a log book from a 94 model 4/4 which gives the same figures.
I have had the car nearly full a couple of times- the last being in June when we came back from Le Mans and didn't want to get caught either getting into the outskirts of Caen and then being faced with all those credit card only filling stations or then having to look for a garage on the late night run home from Portsmouth and the ferry to South Wales
Like a lot of people, I always have problems with slow filling and/or the 'pong' if it is anywhere near full.
When I first got the car, I did a few fairly basic 'trials' and now almost always go for VeePower. No scientific evidence but have always used it with previous 'non- shopping' cars and the MOG certainly seems to go well on it My Aero 8 certainly runs well on V Power - have always found performance cars run much more sweetly on it. Biggest difference is the current RS6 which feels as if it's had it's throat cut on normal unleaded which strangely Audi say is enough. Initial impression of the recently introduced V Power 99 in the RS6 is very favourable - have yet to try it in the Morgan.

Yes, I'm a general fan as well. I've tried the '99' in my 4/4 ( which does have a slightly raised compression over the bog standard Zetec) and it felt very good.
Funnily enough, I've had the use of a Mazda 3 MPS for a couple of days this week and that seemed to go extremely well on it ( All I need now is to get used to that many BHP driving through the front wheels., The diff. did make a difference but it still seemed as though it wanted to put me into the kerb at the least opportunity)

1 imperial gallon = 4.54 litres
1 imperial gallon = 8 pints, each pint being 20 fluid ounces (where one "fluid ounce" is the volume of water that weighs one ounce)
1 US gallon = 8 US pints , but a US pint = 16 fluid ounces so interestingly a US pint of water weighs one pound!
So...
1 US gallon = 16/20 of an imperial gallon (= 0.8 imperial gallon) - beware this when comparing US "mpg" figures
and 1 US gallon = 16/20 x 4.54 = 3.63 litres
Morgan are correct that a 12 (imperial) gallon tank is (near enough) 55 litres. Only I don't believe mine holds that much!
Much easier IMO to stick to metric units (ducks and runs for cover)
Nigel
PS who knows which engineering items are commonly, indeed almost always, specified in "inches" (or "pouces"), worldwide?

Nigel, A wild guess by a complete non- techno and dragged from physics lessons of many years ago: strain?

Thanks GLLGH and nputtick,
I didnīt realize that there are two kinds of gallons.
Interesting maybe that in the south-west USA the speed limits and distances on some highways (e.g. Tucson - Nogales) are in kilometres and kph.
Do I remember correctly that the fuel pumps in England show litres and that the price is indicated in pounds per litre? Iīm not sure about this.
Kind regards,
Andy

Hi Andy,
Yes, you are correct. Fuel pumps do show in litres and petrol is priced using pounds per litre.
The 'gallons' thing is one of many hangovers we have here in the UK becuase we have never fully put into action any policy to adopt metrication. We are SUPPOSED to - but in reality either never have or have only done so on a very half hearted basis!
I like your example concerning the South West of the USA. I seem to remember that in some parts of the Republic of Ireland there might be (or have been) a similar situation with distances in one unit and speed limits in another. Robbie will know the answer to this

GLLGH,
Pounds per litre is less horrifying ...
Some non-metric units are still in use in Germany, too.
We love our wheel sizes in Zoll = inches. Bicycles as well as car wheels. Itīs simpy much easier to buy a 26 inch bicycle tyre instead of a 669 mm. Or 28 inch vs. 722 mm.
The pressure inside the loved tyres is measured in bar, which is almost as non-metric as psi.
Garden hoses and the respective fittings are 1 1/4 inch or 1 1/2 inch.
Diamonds are still weighed in non-metric carat.
And last but not least it sounds much better if our pride and joy has 200 horsepowers compared to a meager 149 kilowatts.
By the way: outside it is cold, only 283 K.
Have a good day
sorry for getting off-topic,
Andy

Andy, No problem.
I also prefer horsepower or BHP
If I have to decribe the power output of a car in kilowatts, I always feel as if I'm driving a light bulb!
