Calculator for fuel costs LPG v Petrol

[JAS21]

Seeing that seedy has put up a fuel comparison chart I though that a cost calculator may be of some use/interest as well. So here is one http://www.drivelpg.co.uk/about-autogas/savings-calculator/ Just input your mileage/mpg and fuel prices. You might have to do a little conversion on the fuel consumption.

It won't be exact as I think it's based on there been 20% more energy in petrol compared to LPG. I don't know what Thailand LPG propane/butane ratio is either but I don't think that ratio actually makes a lot of difference ... no doubt someone will know, post and correct me.

This just gives a guide to fuel costs, not additional costs that may be caused by using LPG. It could give you an idea of break even time for cost of installation although with swinging fuel costs it may not be all that helpful.

We have NGV in the Honda City and the only complaint I have is waiting to fuel. Real pain in the asssssssss.

To drive from Chiang Mai to Chiang Rai on CNG in a 2006 Toyota Vios costs me on average 180 baht, with a fair amount of mountain roads. Petrol is about 400 baht on the same route.

The increase in fuel consumption with LPG or CNG is somewhat offset by an increase in power, because the engine is burning less carbon and more hydrogen. Don't know if it would be the same for diesels converted to LPG or CNG.

A few years ago in Aussie Land I met a guy who modified his Land Rover to inject 10% LPG in with the diesel, said that he had no problems ... having a quick look on the internet I found this http://www.tinleytech.co.uk/lpgsys.html might be an interesting read to some.

And another point of view ... http://www.outbacktravelaustralia.com.au/4wd-mods-powertrain/lpg-diesel-more-power-improved-economy plenty of reading if you are interested.
