Thread: P38 on gas

Usually 0.8 of the Actual Volume... I have an 85L Tank in mine which fills to 68L Usable.....

I generally get between 350km and 400km on mine with that 68L.. however I do a fair bit of highway driving.

I have a Vapour Injection System also (purchased from UK).

As a comparison, I get 300km out of 75 lt on a single point system.
Yes, be carefull who puts it on. The dude (in Melbourne) who put it on 10 years ago didn't use emulators at all, just a relay to cut off the common power. Concequently I get 8 injector faults (no big deal really); but also camshaft sensor, airflow meter, and purge canistor solonoid faults, as the common power for the injectors is the same for the above sensors. So when it's on LPG, it's only running on the crankshaft sensor. He also put in a chip at the same time so the ecu can advance the timing whilst on LPG, but with the crankshaft sensor turned off, the ecu won't adjust timing.

Even though LPG is hard to find in remote areas, in 90% of driving it's as common as ULP, and the fuel range out of 170lt of fuel is reassuring.

In my experience an upper head lube system isn't needed on the Rovers, as they've got stalite valve stems and seats. Dad's been running LPG on all of his 5 Rovers from 87 and has only had one valve burn out.

I've been running lpg for a few years now, and I wouldn't have bought this p38 if it was fuel only.

Check with WA rules too regarding the spare tire. I know in Victoria a vehicle does not need a spare tire to be roadworthy.

The Australian Standard for LPG installations is quite clear: If you fit an LPG tank in place of a spare tyre, there MUST be a suitable new mount provided. Whether or not a tyre is then fitted to the mount is irrelevant. The underfloor mount I make does not affect the load space with the tyre removed.

Quite simply, if a vehicle fitted with LPG has an accident and a loose tyre injures/kills an occupant, the fitter is liable unless there is a mount supplied. I have seen plenty of people too lazy to remount the spare to the mount, but this becomes their problem, not mine.

Even if there is no spare tire?

Mmm, my mistake; I thought I had a copy of the Australian Standards for LPG installation, and there's no mention of a spare tire in there; it must be something else I have.

It's not quite as clear as I remembered (AS1425, clause 1.6 (e) ) but if you alter or modify a spare tyre location, the mounting and anchorage must be designed to withstand 20 g of force in any direction. Removal counts as a modification in my books but I can't outguess an inspector on local requirements.

Have not used these people so cannot comment on reality of this however twin tank set up seems an interesting way of adding more gas without eating into the luggage space.

v8Dualfuel.com: LPG / Autogas conversions and Kits for the Rover V8 Engine

Ran an 1998 Range Rover v8 on gas with injection system for 3 years and 80k miles with no problems. Had a donut tank in place of the spare wheel.
Used the combination of gas and petrol to extend range.

Replaced it with a BMW x5 4.4 v8 also on gas which is the most unreliable car have ever owned. That is however another story.

As 300km per 75L equates to 25L/100km

Mine takes about 57lt for the 300kms = 17lt/100km depending on season. In winter about 330km per tank. I would have liked a bigger tank but I don't want to loose the jack as well to the roof. Loosing the spare to the roof is a real pain especially as now nobody in Aus does a rear bar and spare wheel carrier any more. I'm getting a quote to have one custom made as I type this ( my poor wallet ).

I had single point (a mixer) on my d2 for years (4.0 bosch motronic) and while I loved how smooth LPG was and the very low running costs it would occasionally backfire. I recently had a BRC Sequent Plug and Drive injection system (fully sequential LPG injection) installed by a good installer and it is fantastic. Can't recommend it enough. More low down torque than petrol. Pulls smoothly at 1000 rpm in third gear.
