300Tdi economy

<< < (4/4)

TBH it's not just LR, I've heard Transits, Cargo trucks and Escort vans all do the same.  By coincidence they all have similar timing procedures to the LR :wink:

When I bought my Cavalier I found the pump timing was retarded, possibly to make the lease-car engine last longer and it certainly ran quieter.  As it needed all the help it could get though I adjusted it properly.  Quite a bit more difficult to do but more accurate once done.

Whilst pump timing can be very critical to Diesel efficiency, I'm not aware of any way to tweak it on the Bosch pump fitted to TDi, perhaps someone else here is..........

Al,
Thanks for the replies. Looks like 30MPG is the norm for these suckers. What is the Centane rating of yer diesel over there? 8)

Range Rover Blues:
Don't actually know :?  never thought to ask.

nzoliver:
According to BP UK they have a min of 55. Similar to ours. :o

Dunno why my economy is crap. Will remove the EGR and cat soon. Removed my EGR on other trucks and not a huge difference to economy. Maybe the cat is the problem.
