Thread: 140Km on 50ltr LPG

filled up the work van today...took 52 litres of lpg ,done 349k,on scales weighs 2.2t,so i recon not to bad.

lotza...i havent noticed it runs out up hills,but have noticed it will splutter if lpg is close to running out& i go around a sharp corner.i have always wondered if the tanks have any baffles in them....maybe someone would know.i believe they have a tube to pick up the liquid from the bottom of the tank,which then goes to the gas converter,so if the tank was,say upside down,only gas would come out & the converter would be starved of fuel.

cheers

Well I've discovered that my LPG brain is very hot and this may becontributing to the problem.
I'm getting dyno tested on Wednesday and will see what that brings up.

I would love to see a V8 get 13l/100km's but cannot see how

Not sure why you say that, but 13s should be easy for a std V8 in good repair to achieve. Maybe not a D1, but certainly a D2.

Well I'm just back from the Dyno test.
Max 59Kw on petrol, 61Kw on LPG which is so so. The exhaust is mildly restrictive but good for another 12-18 months so that is staying.

The downer is the Air Fuel Ratio. 13 - 15 on LPG, but a constant 11 on petrol.

So I'm in negotiations with the financial director to get a Haltec chip thing installed which should take care of the poor timing and over fuelling.

By then I'll be due for a return to the LPG garage for the first 1000 Km tweak and if that little lot has not fixed the fuel economy I'll buy a freelander (only kidding).

My '88 injected Rangie, 3.5 = 18L/100kms around town, have stretched to 13L/100 highway cruising with lightweight right foot and no revs over 2000. Am having injected gas fitted in Sept now wonder if doing the right thing.

Yes you are doing the right thing.
Do not let my untuned engine and ultra urban driving put you off.

My mate had his fitted with old gas.
It blew his airbox up in the first month.

Hi all, just caught up with this thread after being away on Simpson trip. I've had sequential LPG fitted to my D1 4.6 HC auto and am very unhappy with perfomance and economy, especially towing. 30-37L/100km!!! Low revs stuff off road OK but not anything above 2500rpm it just sputters and pings.

The system is sold by Elko in Melbourne. Have had it dyno'd 74Kw petrol 64K4 LPG, fuel mix for both spot on, timing set at 10 degrees. Am ready to torch it!!!

Beleive it or not 13-15L/100 for 100k/h highway driving is normal.
around town 16-20L/100 is normal
This is on petrol.

My old 89 3.5 rangie with standard gearing and 5" spring lift was getting 16L/100 on the highway with 37" rubber. around town it was about 22L/100.

My current 90 3.9 is 15L/100 highway and 20L/100 around town (all cold driving unfortunately ), just got back from the springs 4x4 park fully loaded and the trip back (approx 200ks total) brought my gauge down to 3qtrs (which I actually worked out to be closer to a third of my tank used) so I think being fully loaded (with roof rack) made stuff all difference to the highway economy and also it is fairly windy roads at times.

Back on topic, anything over 25l/100 is not good in any rover, be it petrol or gas. I know I would def not be happy with figures like that.

Black betty I would be taking your vehicle back asap and get it checked out.
