Lpg on a 2.4

[big_boz]

Just had a chat with a local lpg company. 

 

Chap suggests a 71l tank fits under the back where the wheel goes with a c55l useable volume.

 

He mentioned 200m local range and 250m on a run (apparently he has a 2.4 Alphard s20 as his daily) and that's his figures 

 

That range seems low, implies about 21mpg on gas, anyone got any real world experience of what these will do on lpg, I'm working out payback miles on the conversion cost of £1150 and with current fuel prices it seeing it as about 14k miles .....which seem a alot. When I have converted cars in the past it's always been 8-10k miles.

Hi potential problem will be getting hold of LPG as a few big names are no longer going to sell it.

Plenty of it where I live have 3 stations less than a mile, not something I am concerned about. 

 

The fear mongering with lpg is somewhat out of date, LPG is absolutely part of the governments direction of travel to net zero, hgv fleet use LPG as EV is not a viable long term solution, the duty escalator has been removed for LPG as a result.

 

Given how popular lpg is on the continent, I wouldn't be at all surprised if in the near future it becomes a government endorsed fuel, with tax benefits and purchase incentives. It's an easy win for the government in terms of emissions reduction.

On a Motorway run and not exceeding 70 MPH I get 33-34mpg from my 20 series 2.4 Alphard and about 26-27 around town so I would doubt the conversion would be good value at the sort of mileage your LPG man mentioned.

The further South West you travel towards Land's End the less LPG you will find; but can always run on petrol if need be.

That's pretty much what I get on petrol so to your point it doesn't stack up financially like it used to.

 

That said last LPG car I had it was 58p per litre seems closer 90p now, so near 50% more expensive, petrol hasn't gone up by the same factor.

I'm getting 31mpg on a long motorway run on a gen 1 hybrid running LPG

What do you get on petrol buddy?

Not a clue as I haven't run it on. I would assume 40mpg is achievable based upon 31 on LPG.

 

Mine is full camper conversion and I rarely push above 60mph on the motorway.

Hi Guys!

We're not owners yet, still shopping!

But I can chip in on the LPG front. If you've had them before you'll know the sense of satisfaction when you fill up of course. And not giving the petrol giants big profits too.

Our Subaru Outback 3.0 H6 is quite a lot less economical than your 2.4 Alphard, 21 mpg round town, 28 to 31 maximum on a good run, but naturally that meant it was paid back sooner.

This time, because I did it to save the money when petrol went right up, I kept a record of fill ups, and LPG vs petrol costs at that time. Mostly 80p litre over the 2 years, even when petrol was £1.90. The Subaru HATES the E10 petrol, flat as a thingy and less to the gallon, but is sound on E5 which of course is now "higher octane" so that was another cost factor.

Having just looked at them, I have saved £2010 in 12,900 miles, at around 24mpg - so not good economy but great at the price!

It was converted in Manchester, and I wish I had gone to the guys I saw in Leeds, as they didn't do a great job this time, which is a shame as it is the 3rd they've done for us. Cost for a BRC kit was £1500. An LPG TECH system on a previous Grand Voyager was £1200 and was just as good, but they were only doing BRC 2 years ago when the Subaru was done.

I'll not be getting our Alphard or Vellfire done by the Manchester guys, no way.

The Voyagers do a little less, 2 to 3 mpg on gas, and they are RUBBISH to start with at 18 round town and the heady heights of 25 on a run, but the Subaru is the same - yes I know it shouldn't be, but it is, must be to do with LPG having a higher octane rating and a high compression engine loving it.

Go on, get it converted, you will save the money eventually! 😄

Cheers!

Hey, I have 50L usable LPG. MIXED usage I get about 225miles. Motorway run 250-260miles. I've done the conversion after I purchased a kit online.
