First impressions...........P38 style!!!

You need a new mobile phone to go with it, Nige... :-)

I always found the trip computer was a little pessimistic. Perhaps 1 mpg.

15-17mpg even on a steady A

on the cruise & got 23.8mpg,

Good to know you like your new toy, overall I'd agree with your assessment - I love mine, especially for my long distance traveling, it is just so easy to do my regular near 1000 mile round trips.

One note about the petrol flap - if ever it won't open, check that you haven't left the key in the ignition - it won't open unless the key is out.

Given your MPG I'm wondering if there is something wrong with my DSE. Best I've ever got is 26.5 (mine's a manual), and that was taking things easy on some nice flat and straight French roads Average is 22.5, pretty much no matter what sort of driving I do, though I do tend to cruise at 80. Any ideas anyone? injectors??

Bloody hell. I drive a car with less than half that engine capacity (2L) and only get 25mpg out of it on petrol.

I must not use this a reason to justify driving a v8..

Take four of the plugs out!

"But think of the money we'd save!"

I aint used it round town yet!!!

Seriously, my WRX only does a max of 26-27 !!

'"gimme the f*ckin' money"

I think you'll probably find that the MPG goes down as you get used to using it. Mine started out pretty high (compared to what it is now!) for the first few days as I was taking it easy, but then ended up where it is now. Still think there might be something a bit wrong with mine as it is pretty low for a diesel.

Yep, but it's a well known fact that the management system on these runs extremely lean at cruise to give economy - at the expense of cylinder temperature, which is said to promote the block cracking issue. Not proven, mind, that's just RPI's take on it, my personal opinion is that the block runs too hot regardless and really ought to have an 82 degree 'stat fitted, but nobody makes one for the P38. Also make sure top hose isn't collapsing internally, landrover have changed the design spec 3 times already..... Nice motors though, wouldn't have one personally as I like my DII too much. :-) Badger.

Didn't someone (Chevy?) produce one that drops to 4 cylinders when under light load?

Yes, later versions of the small-block chevvy V8 can drop to 4 cylinders, but I think it's not to save fuel, it happens when the engine gets too hot so it starts pumping air through it to cool down. I'd imagine that it could be possible to also try to save fuel using that feature but AFAIK it's not the original intent, they are American after all!

nah, twas about meeting some federal emissions requirement. I had in mind that there was a V16 that did the same trick, but I forget whose.

in JVL yesterday was ogling a very smart black RR sport. I have to say, it's a lovely-looking thing. Not exactly an off-roader, mind, but I'd prefer it to the Porsche Cayenne, given the sort of money that justified either.

There's an article on the newer small-blocks on this URL;

They reckon it is to save "gas" although I have to take that with a pinch of salt ;-) They reckon it switches to 4-cylinder mode when under light load and saves about 8% of fuel on average, although there's no mention of how that figure's calculated.

I'd read elsewhere that it drops into this mode when the engine gets too hot, perhaps it's one of those "all of the above" answers as they all make sense.
