Thread: So are there any horror stories about a d-gas setup? Or is it really that good?!

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.

Give the same bloke 2 different cars and do the same trip on same day if possible with same load etc.

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.

up to you though whether you are happy with what you get. in my 4.6 disco on injected gas i am dreaming of 25l/100k.

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

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.

I'm not sure what is good and what is not but I know my Tdi has had the injector pump tweak and is slightly tricked up for more performance without the LPG taken into account yet...I guess that would probably lower economy a bit wouldn't it?

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.
