Yep, Americans thought they would be different and have a smaller pint

maybe it was a method to cut down on food and drink aha (joke

)
There are 8 pints in a US gallon and an 'imperial' gallon.
1 US pint = 473ml
1 imperial pint = 568ml.
Really? I didn't know that! Interesting!
jman what are your prices like over there
weve always gone by the princibal that the cheapest fuel is in a mining town (companys pipe it in massive quantitys cheaply)
and the most expensive is a torist town( torists dont have a choice gotta keep the car moving)
on a differant note why did the us have to hacve a differant system to the world it is mind boggling
thatll show the English we will rebel and fill our beer glasses 100ml less
then they will have no choice to give us independance
Who knows. We've moved to metric on so many things, mainly because we import so many things
Ethanol is not compatable with some of the rubber and seals in some of the fuel systems in any type of vehicle that is why they only use 10 to 15% in the fuel. E85 (85% ethanol) is bad for any system that is not made for it.
That has very little to do with the percentage of ethanol in gasoline. E85 can't be used in engines designed for regular gasoline because the ethanol requires a significantly richer mixture than gasoline. The stoichiometric ratio of gasoline is 14.7:1, while the stoichiometric ratio of ethanol is 9:1. Fuel injected engines designed to run on regular gasoline will adjust the a/f mixture based on readings from O2 sensors, but they can only adjust so much. Anything much past 10% and the PCM can't adequately adjust the a/f mixture. Using more than E10 will void the warranty on most modern cars.
Automakers will not allow E15 at this point because they aren't designing their cars to run on it.
The FlexFuel vehicles you see are designed to give the PCM greater control over a/f mixture. The fuel injectors can vary their output much more than regular injectors. This allows them to compensate for the difference in stoichiometric ratio of E85.
Now, for those of us still running carbs in our vehicles, E10 presents a bit of a problem. Beyond the problem of hoses, seals, and gaskets, with stock jetting, the a/f mixture will burn lean. The 4bbl Holley I added fixed that, though
