Uk Cherokee MPG the same as US? and spring questions..

Does anyone know whether the MPG computer in the Cherokee is calibrated in UK or US gallons, when gallons is chosen as the measurement?

And, whilst I'm here, I'm getting the rear shocks replaced tomorrow. I've also looked at replacing the read (leaf) springs, since I'm towing a heavy load. One source told me that Jeep Cherokee diesel springs were heavier duty, whilst the Jeep agent told me there was only one type of spring ever fitted to the range. He said there was no such thing as heavier duty springs or shock absorbers. I'm replacing the shocks with after market gas shocks, which I assume won't be any worse than what is on it now. Should the rear springs still be fine after 7 years and 52k miles? (with no towing or heavy loads that I know of) although the rear seems to sit a little low. I've measured the vehicle height, which according to the manual is

16.1 - 16.3cm, and measured 16cm approx to below the roof bars.

Thanks Bill. Getting Jeep parts here from anywhere other than main dealer is difficult.

I'm not sure you got the MPG bit - US and Imperial gallons are different, so when the mileage/consumption is selected on the overhead display in mpg are they US or Imperial? Your info was useful though

- does that mean I should try and work it out myself :)

It should be measured in a real Gallon not the unit 'mericans call a gallon.

Or 4.546 imperial liters :-)

F.Y.I. 1 US gal = 3.7854 US liters

I doubt it....

I cannot see the americans making anything with the Imperial gallon as a unit just for one small market. But I could be off there.

When I state mine now, I usually use L/100km or US gal as a reference.

I mean the boys with the Wranglers would crap if I let them know my CJ7 gets a sweet 28+ mpg. LOL!

Actually, it's easy to check - I'll just look at the metric and imperial values and work it out. By the way, the UK was by far the biggest market when the Cherokee was launched in Europe.

Later...

Using the following formula:

235.2146 ÷ x l/100 km = y mpg (US liquid gallon), or 282.481 ÷ x l/100 km = y mpg (Imperial gallon

means that my trip computer showing 14.1 l/100km equalling 20mpg means that the computer is calibrated to imperial gallons :(

It all comes down to booze. In olde England, they had different gallons for measuring different commodities. In 1824 the Brits chucked out all of their various gallons and defined an Imperial gallon to be 10 lb of water, which about equals the olde English beer gallon. In 1836, the US standardized on Queen Anne's English wine gallon (traditionally 8 troy pounds of wine).

Not sure if it deserves the title 'Real Gallon', but of the many gallons defined through history, your English wine gallon is the last one standing. By the way Bill, the gallon originated in France. ;)

The US just wanted to boast they could drink more beer than us :-)

The olde Scottish gallon was three times the volume of the English Beer gallon, so jump in on the next mpg thread and claim 'a sweet 75 mpg' on your TJ.
