Petrol vs LPG payback calculator

Thanks mate. Very much appreciated. It's a Landi Renzo LCS-2 system. Cheers.

This must be you on the LPG forum (I'm also on there): LPG Discussion Forum • View topic - LANDI RENZO LCS/2 SYSTEM BACKFIRES AT TIMES ONLY ON TAKE OFF

That was me Ron. It's a very good system now that I closed the plug gaps up - thanks again Beeutey. It had a backfire recently but I think that was because the Maf was coated in oil and it had a miss on Petrol too till I cleaned it. Interestingly it also made it run hotter especially at idle. Cool now it's clean. Cheers

So .... ;)

I've attached a spreadsheet that will allow you to do a quick comparison between Petrol, LPG & Diesel for average PA (per anum) costs ... you can figure the payback period ;)

... you can see that even though the diesel is marginally more per year to run, the range per fill is more than double ... Where's that LPG bowser in the middle of the Simpson ? :p

I reckon the LPG payback time, dependant on the rebate you get, may only be 2-3 years (assuming a D2 V8) ... however, converting a V8 D2 to LPG versus just buying a Diesel is going to be 10+ years before you are in a payback situation :( ... do V8's last that long in a D2 ? ;)

Caveat - figures used in the spreadsheet are fuel prices as at today at my local BP - Mileages used are as best as I can remeber.

... back to you :)

oh and its a beauty!!
;):p

Come in spinner!

There is no doubt in Brisbane that the cheapest to run is the LPG. Sure there are arguments about country areas etc all well and good (dont go into longevity of V8's though and cost of re-conditioning versus a diesel, cause its not a fight that I reckon diesel advocates can really win:D). But setting that stuff aside, LPG V8's are cheaper to run. Which is what the thread was about.

Cheers

We aim to please ! :p

... and don't get me wrong, I have nothing against v8's ... ultimatley for us, range was the deciding factor between V8 & diesel ... which the V8 on LPG didn't have.

... and yes a V8 on LPG is cheaper to run than a diesel (D2) .... There, I said it ! :o :o :D

And pfillery's post is an eye opener ... when the cost of conversion is way cheaper (SIII) than say the cost of a V8 D2, LPG is a no brainer. Pretty impressive payback period!

They used to tell you 18 months to breeak even on a gas system but that was before the rebate. Plus I bought a secondhand in date tank which cut about $600 off the price, so even with the upgrade to HD flexible gas lines instead of copper ones, price was still very reasonable. I alos do 450km a week which is more than what the average series 3 probably does so it will naturally take less time for the savings to stack up.

I suppose if you care to look at it that way, my gas system is actually making me a profit now of $240 or so a month, not often that a car can make you money. Maybe I should install another one. Hmmmmm:D

and put a hyclone on it;):p

I'd like a dual tank set up like the Rpi one, too. My current 54 litres (usable) isn't enough.
