This is what I would rather believe. 24 'ish

Adrian, is that for real, 30 mpg, ?

I have to be careful just to get 30mpg out of my 120, and I am sure it's a lot lighter, more fuel efficient than a heavy 4.2L

Even 24mpg sounds good. I did just over 300 motorway miles last weekend at a pretty constant 70mph and averaged just 20mpg (12v manual) :cry: I have kept tabs on my mpg for a while now and this figure plus or minus 2mpg seems fairly reliable.

Apparently servicing your injectors and pump can improve mpg.....

I get 26 to 28 mpg towing on the motorway (another LC80 on a 18ft trailer) and have gotten 30 mpg on the motorway being very steady on 56/ 60 mph..
That is on a 12V auto...

I average just under 20mpg around town if I am driving carefully but only about 14 normally driving like a [email protected]
and about 22 to 26 on the motorway...

It pays to drive sensible really but it is sooooo boring... :lol: + these engines are made to run under load to I better give it what it needs.... ;)

oh and when i say gentle, well consider this, my old mk3 golf tdi did 40mpg at 100mph and i had it for a very long time so its all relative (obviously i found this out in germany)

Only had mine for the past month and put 2 tanks of fuel through it.

First one was just pottering around town with faulty viscous coupling but got 24mpg. Second was a run up north, mostly motorway which returned 28. Not bad for a three ton truck.

Cheers

my 12v auto at a steady 70 with MTs, a lift and a fair bit of weight averages 22.6mpg, on biodiesel it averages 23.8mpg

before the tyres, the lift and the weight i used to average 27.6mpg.

My 24v Auto averages 26mpg overall with town and m/way driving.
A lot better than the original 18mpg before I put on the straight through exhaust, and also 1mpg more since the snorkel.

My figures are done with a month of driving and only about 10 percent of that is m/way.

Hi y'all
quite possibly - I regularly get 26-28 mpg at 60-65 mph; mines's a 12 v 1991 auto
(I'm quite gentle with it...well, I don't want to wreck it....she says, still missing it like crazy; poor Beast is still incarcerated sadly
I'm looking forward to flooring the accell on the way to Lincomb Farm (that's if I even get there) :(
Cheers

I've never got the hang of this economical driving lark, it's a mysterious talent that has always been beyond my grasp :lol: 15 is a good number for my 100 pottering about now, 16 would mean I'd done my granny proud, but I read about people getting 20/21 and I think they must get out and push!

I also think the 80 's that are getting 30 are being towed by a 120.

Crispin will love you forever for saying this!

Back on topic, I think that 30 mpg is achievable but requires some fairly gentle driving. At normal motorway speeds etc. I think mid to high-20s is perfectly doable.
I have noticed that if you push it a bit at high speed, the economy plummets quickly to the low-20s. :cool:

I'm guessing that the sub-20 mileage comes from very modified 80s? Roof-racks, bull-bars, big tyres and snorkels all disrupting the normally sleek lines :?:

I think weight and lift are the main factors and maybe the weight of the tyres as I didn't find any difference between 36" Simex and 37" Pro Comps. I think at 3-4" lift you do start messing with the sleek shape though.
