Thread: 3.9l D1 mileage

Yes, trucks do, diesel motors develope torque, sometimes huge no's and do it pretty economically.

Diesel is safe to carry especially inlarge quantities as its very hard to burn or will not ignite on accidents etc.

Diesel is great, i have a Golf 2.0 Tdi.
Its fast, quiet, refined, economical- simply brilliant.

Yet i love my V8 and the high mileage the motors get with much lower maintenance and now thanks to gas lower running costs.

Go the TD5 though.

ok so the figures, i may be wrong correct me if i am, from the last 4 pages i have gathered that people on average are getting

petrol 20l/100
diesel 10/100
gas 26/100

went down to the local servo and from there prices i have come up with a 100km trip would cost

petrol 20x147.9=$29.58
diesel 10x171.9=$17.19
gas 26x069.9=$18.174

so from that v8 on gas and desiel are about the same running cost however v8 is generaly cheaper to buy but you wont get the distance out of it so you sacrifice distance or power for power or distance am i wrong

Eraser - thats some pretty sensational stuff matey. I have my 3 kids and wife in an LPG disco and my other Disco is LPG also. The tanks are hand seam welded 3mm steel and the scuba shape of them makes them incredibly strong. Then consider that they sit inside the massively strong disco chassis rails and have a further bracing section around them - they are much safer than petrol tanks in the same position. BTW what is perhaps not widely understood is that in Australia we have 2 solenoids - one at the tank and one at the convertor in the engine bay (in europe they have one). Both of those solenoids are energised in fuel injected motors to open only when the engine is running (tachometric change over from petrol to LPG), AND when the engine stalls or is shut off via the key those 2 stop energising and default to off under spring pressure...and as such cannot flow lpg. So if the LPG line is severed (which is damn hard to achieve) the LPG still cannot flow...so its allways OFF after an accident if the car stalls or is turned off.

I dont accept that emergency services would stay away from a vehicle with an LPG tank until the fire dept arrives, but lets face it their response times are usually better than anyone else anyway.

My LPG lines where they run through into the engine bay are cased in 1/4 inch treadplate to stop puncturing from a tyre blow out. If an LPG is installed correctly they are perfectly safe. As for saving a "few bucks" thats absurd. I save thousands a year in running my V8s on LPG. Clean, safe cheap and plentiful and best of all not linked in price - in Oz - to crude despite where it comes from.

Anyone looking at LPG please do the research and make an informed opinion not one based on someone knee jerk reactions.

jeep boy - my D2 in and out to town - peak hour and non always gets 21-22 litres per 100k ON LPG...and no with towing it has more low end torque than petrol and it tows by 2 tonn boat (21 Seafarer Vagabond) very well on LPG. I never bother towing on petrol unless I have run out of LPG.

So..compared to diesel its significantly cheaper for me and tows very well.

Cheers

like i said i wanted to be corrected if wrong so going of that it would change the gas figures to

21x69.9=$14.679

being i do on average about 500km a week this would mean that a week the cost would be

petrol $147.90
deisel $85.95
gas $90.85
gas $73.35

i have a light foot as i have a 4l s6 wrangler at the moment so gas wouls be best for me but like anything horses for courses

at a year price it would be

petrol $7690
desiel $4469
gas $4724
gas $3814

so even without the gov rebate on gas in a year i would pay of the conversion easily, as soon as the jeep sells ill be looking like a hawk for a disco i was thinking 300tdi but now im thinking v8 on gas, what are waiting times like to get gas installed can i drive somewhere to have it done quicker anyone got pics of boot setups with gas tanks ill be doing touring but maybe once a year so if i cant get gas in remote places it wont worry me running on petrol when i cant get it and from what i know you should run it on petrol every so often anyway

you are about the distance,,
as many V8's as diesels get to high mileage,,

Agreed Pedro - I just posted up a longish answer under the D3 thread about petrol v diesel miles...and also the staggering cost of a reco or new diesel at the end of those miles compared to a petrol motor.

Cheers

what is the cost of both, i would imagine a petrol to be cheaper and easier to get
