Mine cruises happily at 100-110 in sixth.

At 2000rpm it labour’s unless on the flat at 80 5th or 100 6th.

At 3000rpm the idlejack holds slightly longer, gear shifts are smoother, fuel economy is better IMHO.

I have the full length LR expedition roof rack, no towing and can only manage 11 or just under for open road and 12ish city.

Straight through pipe,no Cat,unplugged EGR,down change at 2000rpm,upchange at 2500.I don't drive for economy unless I have to. Pat

Well, my 110 is stock, no changes.
I used to get 10 before I put the roof rack on.

...so is driving for economy changing at 1000 or 3000?

My engine works best between 2000rpm and 2600rpm,so if the rev's drop to 2000 I go down a gear,if they go over 2600,I go up a gear,I drive by rev's not road speed.I have towed with my Tdi and TDCi a lot with some very heavy loads,I've found the Tdi likes to rev,the TDCi not so much. Pat

Interesting Pat, is yours the 2.4? My 2.2 definitely prefers an up change around 3000rpm. 2600 and it’s only just beginning to purr. ...down change around 2200rpm
