Uk gallon v usa gallon

[Stingray01]

I know the U.S. gallon is four fifths of the U.K. gallon. Recently bought a 06 C6 american import in atomic orange. Does the cars computer read out in american MPG. If that is the case I'm doing quite well as I average 21 mpg on computer readout so in reality I'm making just over 25mpg. Is this correct.

Cheers.

Yes, they work in US gallons.

Suggest you note the fuel pump readings to tell you how much you're actually putting in, and calibrate the odometer on a motorway, if you want to know the true economy with any accuracy.

[LuS1fer]

They're reasonably accurate. It's surprising how big a difference there is - plenty of instant conversion tools on Google. 20 US is about 24 UK.

The odd thing then is that you can't stop telling people how economical your 6 litre V8 is even if they think you're nuts and won't believe you so don't protest too much. The fact is a Vette is as economical as any Focus ST.

In EVO this month they test the new BMW M3 V8 with 414bhp and got their consumption down to 11mpg - frankly that is unacceptable when the Yanks are so much better, however hard it was driven.

31.5 US mpg = 37.8 UK mpg

Atomic orange, my favourite.
Got any pics Sir?

[Stingray01]

Thanks for the replies gents. Yes a few people have said that I must be down to 10 to the gall. with 6 litre but when I tell them I get 21 overall in town/traffic/motorway they cant believe it. Just sold my gtr r3 skyline and that was about 15 to the gall. I will put some pics of the car up as soon as I get chance. The car has got the performance pack taking it uo to 465bhp with side by side quad tips. so not that far behind the Z06.

I thought Atomic Orange was new on the 07 model cars (steering wheel stereo buttons the only obvious difference). Probably the slightly silly practice of making the next years cars half way through the current year!!?

[Stingray01]

Rob, the C6 is registered 1st January 06 in atomic orange with tints, don't know when they bought the colour out but I believe it is an optional extra. The car has every extra on it which I believe it's the L3 and has the handling package. The SLP performance pack consists of high flow cats. S/S/ tips. Cold air induction, long tube S/S headers and exhaust. X pipes, 1.85 ratio rocker arm kits. 160 degrees thermostst. Diablo sport11 power programmer with SLP custom tuning, ZL 465 badges. taking it up to 465bhp from standard.

It'd be interesting to see that colour, the photos seem to very from a dark orange through to almost a bronze colour depending on the lighting.

[Stingray01]

I searched high and low in the U.K. for the orange colour and finally found it. Yeh, the colour changes from deep to light depending on weather and light. I'm quite sure that you could have this colour from the factory with varying tints for about 750 - 1000$ Well chuffed about the fuel consumption though.

The conversion from US to UK gallons is very simple and it is very exact. Both gallons are 8 pints and that is the origin of the problem. A US pint is 16 fl.oz. and an imperial pint is 20 fl.oz. I've seen people claiming US gallons are x litres and imperial gallons are y litres, but that's just complicating matters. The imperial pint is 1.25 US pints so the imperial gallon is 1.25 US gallons - exactly. If your mpg is 20 mpg US it is 25 mpg imperial. Not a difficult calculation at all.

Incidentally my C5 returns (all these are imperial mpgs) 25 average, 30 on the motorway and 14 on track. Not bad for an automatic with a 5.7 V8. That new M3's fuel consumption is absurd

Sorry, but you're wrong. The conversion factor is 1.2, (actually 1.200949926) for both pints and gallons, so 20 mpg US is 24 mpg UK.

Managed to get 36mpg when doing 70/75mph on the motorway in my C5 Z06.

That's correct. The reason AdeTuono has it wrong (despite his confidence) is that UK & US fluid ozs ore not exactly the same size.

Suggest you look here...

...irrespective of fluid ounces, 1 UK gallon is, was, and will continue to be (until EU law decrees otherwise) 1.2 US gallons (near as dammit)

And 1 US fluid ounce is 1.04 UK fluid ounce.

Well, that's interesting as Atomic was an '07' colour and the first customer cars didn't get delivered till at least July 2006

Good luck to you if your car came from the factory in 'Atomic Orange' or got resprayed somewhere along the line, but just maybe you have 'Daytona Sunset Orange Metallic'

Check your paint code 'Atomic Orange' is 83U
'Daytona Sunset' is 71U

compare here, the DSOM is in the foreground, Atomic is behind........

Terribly sorry - I assigned the incorrect conversion to the wrong person. It was need 4 speed who incorrectly assumed that despite pints and gallons being different, fluid ozs would be the same.

Try running a big block Vette and it all becomes academic.
US or UK gallons its bad - at best low double figures town or highway! you lucky efi electronically controlled C4, C5, C6 and ZO6 freaks!

[need 4 speed]

I stand corrected - I don't remember school teaching me a fl.oz. was different on each side of the Atlantic. Thank god there are litres and kilometres!
