Fuel consumption

Post by Stewartuk »

Hi folks

What would you reckon is a normal diesel mpg. My P93 718 is doing around 20lt/100kms. Is this a typical fuel use.

20 l/100km = 11.7607 mpg (US)

Unfortunately, it's been 6 years since I sold my P80 716 w/ manual box, but (iirc) the typical mileage wasn't much better than the mileage was in my 710 or 712 which was 11 ish :roll: But generally, most trips were short 'in town' and hard on mileage
My ATL 718k w/ 2.5TDI and auto box has gotten 15 +/- mpg (US), when I did check it.

Thanks. Some of the problem is it takes a while to get all that 6 wheel drive mechanism up to speed. The turbo lag in that old 2.4 doesn’t help either. Have you heard of anyone who has successfully fitted a variable vane turbo. I know s tech considered it a while back. I could go down the route of fitting the 2.5 but am not so keen on the electronics. There might be a few engines coming up as the UK army are releasing a few hundred Pinz over the next year according to rumour

Cheers

Hou could make your 2.5 TDI work with a mechanicle fuelpump, they cal it a M-tdi. I have a 2.5 in my 716 p80 with a pump Like That.....works perfect :wink:

Hi Pinzi

Where did you get the mechanical pump from for the mtdi. I had a syncro many years ago with a mechical mtdi pump from Bernd Jaeger but he does only the 1.9. What did you use for the turbo.

Hi..i have a 2.5 tdi from a 99' Volvo v70 in my 716 so i only had to built a right engine mount , the left one is the one came from the 2.4... the turbo is the original one on the 2.5 TDI. I had my pump done in the Netherlands by DA-BART this guy is or was active on the vw tdi forum but i Hear he is now in Saudi Arabië? Mine is a automatic and the zf 22 fits right against the 2.5....?.i dont think there is a lot of diference between the 1.9 and the 2.5 pump only That the 2.5 is a 5cyl and the 1.9 a 4 cyl. The driveshaft from the zf22 to the hi/lo case needs to be made about 5 cm longer as the 5 cyl is shorter. :wink:

My only experience with this style of truck is with my Landrover FC 101 - it is of similar size and weight to the Pinz - cruises at 100kph - I get 19l/100km on an easy drive on the highway and in mixed driving about 22l/100km. I guess similar to what you are getting but my vehicle is running a 3.5 litre petrol V8 so your diesel should be doing a lot better.

My RRS 2.7 TDv6 pulling the 2.5 tonne car (it weighs more than the 101 empty) at 110kph gives 7l/100km and about 10l/100km around town but it is a modern high performance diesel. I would expect the older style diesel in your Pinz to be giving around 14-15l/100km (or better) driving along at your normal cruise on the highway (85kph?). Our ex Army Landrover Perentie 110s with their Isuzu 3.9 4 cylinder diesels average around 12l/100km cruising and the 6x6 versions a bit worse.

So I would say your fuel consumption is too high and should be investigated.

Good luck.

Yes its a bit hi but i always found the 2.4 a bit under powered, if you have a automatic Like i have its Like every Time it shifts
The 2.4 takes time to speed up i mean it shifts waits a few seconds en then goes, while with the 2.5 it just shifts and takes of there is no gap....i think its thanks to the higher torq That the 5 cyl has against the 6 cyl. With this said and becouse it drives and shifts better feul consumption goes down, i have about 14-15 l . I know there are 3 versions of the 2.4 being used in the Volvo 700 series....the frist one being a flat 2.4 6cyl then came the 2.4 Td (same as the pinz) and then the 2.4 TIC same one but with intercooler...the last one having 122hp, still a bit underpowered in the 716 so defenetly in a 718. :roll:
