T4 5cyl LPG

[Racemag]

I seem to be doing more km in my T4 DOKA syncro, but 16l/100km around town is not good.
I enquired about LPG, but the only system offered for a 5cyl is the old vapour units. Has anyone seen the gas or liquid injection conversions locally as done in the UK?

Hi Racemag, I am currently running a T4 5cyl with Lpg. I use about 20L/100km, so it is saving me money, but I am not the biggest fan of the system. It is a vapour unit, and under the bonnet is a nightmare of wires and pipes. It makes maintenance a big drama. I have scuba tanks under the centre of the car, keeping all my luggage space, but reducing rampover a bit.

Just make sure that you get your money worth for your investment, when installing into the older vehicle. You can buy a lot of fuel for the cost of install.
How many km on the van?

a lot, over 400,000km.
I'm restricting my use of it as it gets around 15l/100km.
If I look at a tank of PULP 95 RON as costing $90, LPG is half the cost at $45 plus 30% extra use for same km traveled. So say $60 for KM traveled, which is a $30 saving. So 100 tanks of fuel to pay back investment of conversion.

just got a ball park figure of $2500 (after $1000 govt rebate) for lpg injection.

Conversion done - vapor injection and 114l fill tank on the tray. I put 90lt of LPG in and it cost $62...normally the numbers are the reverse of this! Initial driving report: what LPG! Frankly I cannot tell when it switches from PULP to LPG, which it does by itself. It starts on PULP and self switches when it is warm enough. It may have slightly less torque as evidenced by acceleration on really steep hills, but it is very tough to tell.

Well done glad to hear you had sucess wit the conversion , you are right about LPG on hills many years back before I switched to VW I had a new Ford panel van XF series converted to gas and the same thing about hills would flick the switch to petrol in hilly areas or it would just go slooooowwwweeerrrr LOL

[Racemag]

Oh it goes slower with petrol too! there's no getting away from the fact that more than two tonnes and 85kw are going to struggle on an incline. Now I have to resist the urge to drive harder because the fuel is cheaper!

What engine is yours exactly as my son has a T4 with around 300 thou plus kays on and it pulls like a Mallee Bull he does complain about fuel consumption . But you know what young ones are like they cannot understand that if they drive short trips to shops and back girlfriends etc that economy just goes out the window . In fact my T5 with the 2.0 petrol seems almost lifeless up hills in comparison to his , one particular hill near our home his will sail up in third gear and is still accelerating at the top . Mine has to be paddled furiously , third is useless by half way up and second gets you there but with nothing left under foot .

It has the 2.5l AET engine in a 1996 DOKA (double cab ute). I drove it a bit today. Startup as usual and then 500m down the road the car switches to LPG all by itself and so it continues. Got to the shops and 20 minutes later it starts on petrol and 30 seconds later is on LPG.
