So i have to drive to Cornwall Thursday for a last minute meeting
It was 260 miles from brum and i filled up round 85-90 litres
cost around £35
didnt go over 70mph
drive was quite steady, no real traffic (at 5 in the morning) and got there around 9.30

Drove back and got to 320 miles before it swtiched back over to something called petrol.
So not to bad!
£35
Bargin!

Checked my tyre pressures today and they were all down below 30.
From my trip i did expect a little more and i know ill get more new the pressures are correct.
Doing the same trip again soon so will see what the difference.

Did you actually get 80-90 litres into the tank, or are you saying you filled your 90 litre tank? (20% air gap etc)
But yes, well done anyway. You can't go wrong with LPG on these engines.
