well i did 427miles round trip on one tank of lpg and i stuck £7 in as it was not full when on the A406 as the mrs had been using it for the past 3 days on the school run
it was all motor way miles at around 40 to 70mph but most of the time at 50 odd as it was Dam Wet at 4am
the car is a Zafira Gsi with 320bhp
Tubbs wrote:34.8 mpg. Thats pretty good. Did you drive like a grandad
i was on the M1 all day in the Rain so i was stuck at 30 to 50mph for 80% of the time on the way home till the M25 then i could open it up
but I did have 2 Z20LEH engine's in the boot so could not go mad on the motor way
