US gallons and UK gallon are a different amount, P38 diesels tank holds 20 UK gallons.

Capacity is quoted at 90 litres or 19.82 imperial gallons. John then asked for US gallons and i converted it to 23.8028 US gallons. From my flying days convertions, think a US gallon is around .87 of an imperial gallon.

Welcome to the Dordogne - hope the weather cheers up a bit for you soon
British stiff upper lip and a good brolly we'll have a good time, visiting family just outside Gourdon, don't care about the weather really. Theres plenty to do around here, the caves at Padirac and feeding the monkies at Rocamourdor, although there maybe 2 more monkeys there by the time I leave.......

Acouple of months ago I wanted to see what mine would do over 3/4 of a tank (real world average) so filled it and achieved 24.25 miles/UK gallons, this was mixed driving (A roads, B roads, town, stop/start). I am also quite heavy footed so this could be bettered but wanted a real figure not what could be achieved. Its a 2.5 DT auto on 157K miles.

Best I've had out of mine is 580 miles while searching for a bloody garage that would take my card in the middle of the night, the red light had been on for ages and I got over 87 litres in when I finally managed to find a garage.
hi i dont know if this any help but i do a bit of both.. driveing in london stop start and on the motoway......i get 18 mpg around town so a full tank gets me 347.4 miles and on a run i get 24mpg so i get 463miles out of a full tank..a full tank will cost diffrent price. depending on where your from but it will cost around £110 to £120. i think youll still have around £30 left in the tank when the red light comes on so you should get a good 50 miles out of it. but the only way to be 100% get a jerry can full of disel in the bootSorry, it wasn't on page 2 when I started posting, then got distracted!
OK, so to the red light it's probably between 350 and 450 miles depending on cruising along or more inefficient use!
Thanks
and as soon as the red light shows set your miles and let it run out..hi wot mpg was you getting as looking at the miles you get from yours
. there is something very wrong with my car i do drive with a heavy foot:crazy_driver: but best iv had is 465miles at 24mpg.. i have had mine for over six months and it is due a service so it could be down to that ...did you do the miles with or with the power box on your car. as that could of made all the diffrence??

hi wot mpg was you getting as looking at the miles you get from yours
It's only 6 mpg difference. Maybe your lead foot accounted for that.
hi mr wammers hope all is good
mate only six mpg thats a lot over a full tank where talking around 120 miles diffrance. is he getting 30mpg out of his car. i dont think hes telling porkeys at all.. im just wondering how he gets that out of it so i can do the same or should mine be that good allready... but is in need of a good service:doh: ....you could be right as you have been every time befor but i dont think its down to a heavy foot. as once your on the motoway its 70/80mph all the way i was wondering weather he got them miles with the power box on the car or off. as i think he said he was going to take the power box off?? or was going to put one on. and that something iv been thinking of doing to mine or a chip... now it looks like ill be keeping it for a bit longer

I agree with Wammers on this one, while on the journey down there were some very long slight upwards inclines on the auto-route, used extra power to maintain speed, at times l didn't back off once on the downward slope, soon found myself doing 90/95 mph at times. To lose 6 mpg is easy, terrain, road conditions, head winds, driver error and in-correct gear use.

Yeah but it depends where you're driving your car, around the Lake district will give a lot different results than around Lincolnshire. A heavy foot and traffic laden town will easily use 6 mpg more than constant A road or motorway driving. Driving at 80 instead of 70 will also have an effect.
all i can say to that is wow
lol... and ill be thinking of you lot on my next trip i think ill try 60mph next time do you think my mpg should be better or dose it sound about right for a p38 disel ?mate he has to be right hes the man
im just a bit shocked 120miles thats a lot.i dont no the bang on figgers but id say im paying an extra £40 every time i fill up not good:doh:

Max torque is develvoped at 2500/2600 rpm if my memory is correct, 2750 is 70-ish pm but once you drop below 2500 rpm the power falls away fast. 3000 rpm about 80-ish.
Personally I feel 60 mph is to slow for economy in 5th gear.

I've got a very small pension and as a result a very light foot. Not much traffic on the roads I use, regularly get 30mpg on a long run cruising at between 90 and 120Kmh according to the limits on the particular road. Around and about my long term average is 24mpghi wot mpg was you getting as looking at the miles you get from yours
The MPG is much the same with or without the powerbox fitted, I used to run a powerbox until it cooked the auto box now I run without, at least until I get the box changed. Local MPG is the same with or without the powerbox unless you believe the dash display, on the auto route MPG is very slightly better with the powerbox. All my figures are from brim to brim calculations, not the display With a lead boot I can get the MPG down to 18. :-(im just messing
i could not do 60mph for more then 2 min id go crazy im going to be hanged for saying it but i do a london to dover trip once a month and do 110 all the way there and all the way home...i no its not good so please no need to tell me but i just have a need for speed i cant help it ..i drive a range rover to slow me down.....i have done the trip with the wife and kid in the car and thats where i got my best 24mpg as i DO NOT drive like a cu.t with them in the car ever. but shes not comeing agen. she would not stop talking and it seemed to take for ever lolhi thanks for that . my old range rover was getting around the same as yours 21mpg around town and 28 on a run but it was chipped. i think ill get mine a service. i think the mpg on my new p38 is a bit low and should be better but your right agen i am only going on wot the dash is telling me.I've got a very small pension and as a result a very light foot.
