Post by: disco2 td5 on May 23, 2010, 18:42:34: 14-16mpg on petrol On gas I've heard they are about the same if not slightly cheaper to run as a td5 and they do about 25 mpg it's not good but it's a 4x4 heaver than the moon and has the airodinamics of a garden shed so it's never goin to be good lol

I used to have a LPG disco, open system, with a single mixer rather than sequential injection. Crude, but it worked well....

I used to get about 2.5 miles per litre of normal driving. I never ran it long enough to know how many miles it did on petrol! (That works out at about 11.5mpg).

Poor economy is an ealry symptom of cam wear/cam chain wear BTW.

Post by: Range Rover Blues on May 26, 2010, 12:59:31: I don't know if auto box makes that much difference, my sister's TDi is better than ours and hers is the auto. Both our V8s are similar too.

Let's be honest, it's a LR, they'll never be economical!

Surely LR3 & 4's must be getting around the 25 (if not more) average :-k

Post by: Range Rover Blues on May 29, 2010, 15:19:55: Too true, my sister gets 30mpg on her 300TDi auto but drives it very sensibly. I never get that kind of economy even when I try really hard to behave :lol:

assume 25mpg and you'll not be far wrong
