I think with mileage, there are soo many variables like, speed, wind, driving techniques and fuel quality that its too hard to compare just any 2 cars.Quote:

That be a fair comparison.
sold them both now but if i didn't get 10.5l/100k around TOWN in either the manual or auto tdi i would be disappointed. 700km a tank does seem quite low.Quote:

Manual 300Tdi, I would constantly get 850-900km day to day off 75-80L.Quote:

Don't TDi 300's get that sort of milage on a tank of diesel anyway with out the expense of added lpg? I'm sure I've heard people claim that milage?
Pure highway I managed 1150 once off 86L. Always filled up the neck so constant fill volume.
Its really not that hard to get good economy from them. Drive to their torque band, don't drive like a sissy all the time. Never heavy brake - time traffic light changes and keep it moving.
Mine had a 2.5" mandrel enhaust, one hi-flow muffler. 2" lift, 31" tyres. No gas.
Everyone who has Gas fumigation, and who has posted loves it.
There are no posts that I have read of anyone disliking it or having problems or motor damage as a result, from anyone who has lpg fumigation.
There are a few posts of motor damage caused by LPG fumigation but these always seem to be some one who was told by some ones second cousin who is married to there grandfather who is also there uncle etc.
There are a few posts on economy both in liters used and cost vers return etc etc
There are many posters who have lpg fumigation who will not post because of the self promoted experts who don’t have lpg fumigation and there constant bagging.
I know of 2 300 tdi’s that were put neck to neck. Both autos one well molested ( 200 tdi manifold etc) and tweaked with no gas. The other only the center muffler cut out and the off boost tweaked a bit.
There was nothing in it, apart form one being cheaper to run and the other rolling a bit of coal.
my NA with lpg fumigation, well i wouldn’t be with out it - brilliant for what it is.
infact i don’t know anyone with a Isuzu county nowadays who has not got LPG fumigation.
for fuel economy numbers with routine driving the discos hitting 850+k to the warning light in city cycle and often breaks the 1000K mark for constant highway cruising.
Well a disco can be tuned either way, economy or power. neither return the same economy numbers.
Best i have ever seen is a 200 tdi LT77 disco, 6.9 ltrs per 100. tail gateing a defender all day.
Haha yeah the V8 certainly is a different story.Quote:

Wow 25l/100k..... I take it you have a 4.6 Rangie motor in yours?? I get on average about 19Lt/100km around town, and about 12-13lt/100km highway cruising all on Petrol. I've been tosing up for a while now wether going LPG is the way to go. $4500 minus $1500 rebate is still a lot of money to part with. I'm still not convinced that the LPG installation is thorough enough, and after talking to a few people that had it done to their 4x4's, they don't seem to think it makes much difference at all, and in hot weather the systems fail all together forcing them to run on petrol until the ambient temperature drops below 32 degrees, not to mention the electrical issues. The vapour injection is definetaly the safer option for Rangies, but the high price for these kill the incentive. Even though the engine runs a bit cleaner, you need to remember that petrol engines were never really designed to run on gas, and therefor modifying it to do so on an aftermarket basis is a form of non- approved modification. If Range Rovers and LandRovers in general for that matter endorsed LPG as a factory option, or even recommended it for conversion via instructions of altering the original ECU to suit (instead of fooling it with another sub-ECU), then without a doubt, i'd straightaway go for LPG. But at this stage i'll stick with Petrol.Quote:

If you do the math I think the V8 on lpg was cheaper to run than a Tdi getting high km from a full tank, only you had to fill up the lpg twice more than the diesel. Put some sill tanks on the V8 though and you'd have more range which I would have done if I had not sold it (the person buying it will probably do that), or you could have the lpg tank in the boot and take up most of your boot space but this just was never an option for me so I made sure I bought an lpg Disco with lpg scuba tanks under the back floor instead.
I bought my V8 with a good lpg system installed already, but I would not have paid that much money to have one installed if I didn't already have it, I'd just run it on petrol and pay less for the car in the first place...hypothetically of course ;)
