TBH, We run a 300TDi and it does about 27 MPG, I've fitted a bigger intercooler and electric fans so if I'm carful it shoul dbe better than average, to be fair I havn't had it on a long run since I did the head/intercooler and I havn't replaced the injectors yet.  My sister has a 300TDi auto and it will do 30mpg if she is careful, and about 21 towing.

I also run Blue on LPG and cost per mile there is little between it and the TDi, you have to watch fuel prices though, 10p/ltre on LPG hits really hard, plus the TDi will happikt take vegitable substitutes.

Thing is, will the cost of swapping to a TDi pay you back in the difference in economy? if not get a noddy car for work.

I was looking at a 2.5 diesel. I'm finding hard to justify the running cost's when I can pick up a nice 2.5 pajero for £800 and it'll run all day on 100% veg if need be  :evil: Wont tickle the happy gland like the v8 tho  :'(

If you are going to get a 2.5 Paj, make sure you service it really regularly, or get the 2.8 (Still need servicing, but the 2.5s are known for cracking heads) and the difference in MPG between the 2.5 and 2.8 is marginal if any.

Saying that... my 3.5V6 Shoggy did 19mpg, the 2.8TD did ~21 - 22.! I would get the 3.5V6 if I was getting another Paj (and have throught about it, although the LC amazon is more likely for my tow car now)

Just my views of course. there are a lot of okay 2.5s about, but I have heard of a lot of them with head issues.

That sort of money gets you a new single point LPG system which could return similar running costs.

Personally I am a big diesel fan (especially large ones) but in this case I would agree with LPG.

Why change if you know the car and know the engine - just make it cheaper to run.

Mind you it will be limited - Gordon will tax LPG to death as soon as enough people are using it.

What was that in the budget about ending the tax incentives on bio fules? LPG is not a biofuel of course but it won't stay half the price for ever, though it's a waste product of refining petrol (in part) so it will always have to find a market.

the next big thing will be Compressede Natural Gas, my LPG system is already built to take it, though I will need a new tank.

Basically methane AFAIK, yes I can run my car on cow's farts if I can catch them :lol:

All true; when you go up the North Sea it's frightening the amount of gas being burnt off from the rigs.
Will that stop Gordon from taxing it? Will it hell.

Don't mention running a car on cow's farts or Gordon will put a tax on Flatulence.

Despite the fact that it'd be removing a greenhouse gas :roll:

Not to worry though, have you noticed how chancellors never tax things that will hit themselves? well the amount of bull**** that comes out of westminster, CNG will probably be tax-free :lol:
