Tanked up the 2.2 with gas at High Wycombe at 67p lire (damn its good be to be back on gas!) before weekend, drove from High Wycombe to London, with roof bars and a bike on the roof at nice steady 70mph.

Few days later, drove to Bristol, then onto Monmouth in South Wales. Late nice cruise so 80 all the way, next day, return trip to Hereford in heavy traffic.

Came back last night, in some crappy M4 traffic, lots of stop start. Now the red light on the LPG gauge had been on for 20 miles or so, but I always could get a decent amount before it ran out when in red.

So tanked up having done 338 miles, all on gas, I was expecting it to be empty, but only got 56L in 

Usually its around 70 ish when empty! - I can't remember how the gauge is set, recall its just manually entering amount of litres to each LED? 

2.2 averaged 27mpg on gas, about same 3.2 does on petrol, apart from fuel costs half as much

Could be:

Pump inaccurate
Pump cut off prematurely
Float a bit sticky after being sat for a year unused


But to answer your question, yes

Gauge on the tank itself reading full, well full-ish after driving 40 miles from filling up.

Plan to run it completely dry next, until it won't switch.

The LED gauges are terribly inaccurate. I dont even bother with them, just use my odometer. But see what the gauge at the tank does first, before changing anything.

The LEDs can be calibrated in the software but it's Voltage (I think) readings and fiddly

Well on my calculations 338 miles and 56L went in, I've been known to get 72L in when its beeped, switched back, then beeped again, so very empty!

So call that 3 gallons roughly I could have got in, at 27mpg average, thats 81 miles. Giving possible 419 mile range 

Which was what I expected on a very long run, should have ignored the gauge. Filled at BP which was 10p litre more than Asda
