Gas vs Petrol

Shivaga · #1 05-09-2005, 12:47 PM

Hi everyone, just wondering what the pros and cons are with petrol and gas engines. like mainly power output, and cleanslyness and the difference in maintenance needs.
Its just been a question thats been on my mind lately. I know it would be cheaper these days with gas, but yeah...you know what i mean!

gas cheaper, higher octane, rating still as safe as petrol has no cons except you have to pay to get your car converted and you still have to start your car on petrol.

petrol burns dirty, has lower octane rating pros you can put petrol in without modification

in other words if you have the cash go gas you dont loose power if you get a good conversion with a dual computer setup in fact i got a quote the other day dual fuel with guaranteed no power loss for $2350 brand new installed etc dual computer setup

OK
with a camary i would use the gas to cause an explosion, and get the insuance money for it........

Seriously, using LPG has compremises. Often using dual fuel LPG the economy is worse than with petrol (say 30% or so). To recover intitial setup costs of say $2.5k and assuming you are running econimy with the camary of 10ltr/100km

therefore
Assuming lpg=50c/ltr and petrol $1.30/ltr. and economy is 13l/100km on lpg (7.69km/ltr)gets out the calulator..........

Formula ((setup cost [$2500])/(savings per litre petrol-lpg [$0.65]))*(km per litre [7.69])
=29,576 km to recover cost only.

If you done straight gas conversion , with increased compression, specific computer porgramming etc etc (say capital cost of around 6-7k$) you would be looking at a hefty 75000km recovery cost.

Worth it----------------well erm um NO!!!

Hehe, good call on blowing up the camry (sorry dude..)

Geez, at that cost I aint going to do it, but was curious too... oh well...

anyone who buys a camary needs to dontate thier brain to science, so that the wise sicenteists can determine the persons illogical thought patterens.

30,000kms is what i had figuered for money back also. straight gas not worth it no but dual fuel yes if you plan on keeping your car for a year or so.

However you then have to think with the consistanly rising costs of fuel you would get your money back sooner that you would think.

i have a mate with a VP commodore on gas(dual system). mixed highway and city driving he gets 14litres/100k. in Brisbane were paying .43 cents / litre therefore 14/l/100k = $6.02/100k's.

i have a VS V6 which uses 11odd litres/100k mixed driving = $14.40 @$1.20/litre

at this rate i know the next car i buy i will get a dual fuel system. i will save approx $40 per week driving 500k / week. i won't convert Calais as it has 220,000 on it and will upgrade in the near future.

i have driven a AU Falcon S3 on gas around town used 20litres/100k. $8.60/100k

if i was doing a car on the old LPG id either do it when i first bought it. SOmetimes u gotta assume you had the money on intrest (say like a visa), then the payback km's would be increased.

If buidling a performace engine though, and running it on straight gas, you dont need cat converters, and emmissions are far less, so you can have a more radical state of tune, but for a camary well id say its not worth the expendature.

hey guys
thinking about converting my VX Comm Sed V6 to LPG but there is so many ways about doing it and so many different systems. Just want some good info

Shivaga · #13 07-09-2005, 08:21 AM

ok you mean bastards (jk), i wasnt thinking about it for the cam, more for just knowing what was better. And i'll let you all know:
1. I never baught the camry, its still in me mums name, i've just been driving it all year!!!
2. I'm in the market to buy my own car!!!
3. I've found a sweet HQ and you'll prbly see me in it at the Xmas meet!!!

YEEEEEEEHHHHAAAAAAAAAAAWWWWWWWw

It's been stated here that converting to duel fuel is around $2500, but someone has also stated that a DEDICATED conversion is $6500. "Holy blistering barnicles Batman!", that's a huge difference in price.

I was considering a full DEDICATED conversion for my caprice, but If that pricing is actually correct then "I don't think so Tim!".

I sort of liked the idea that I could rip out my existing petrol tank and shove the lpg tank in its' place, therefore not loosing any of my precious massive amount of boot space.

Does anyone have any particular recomendations in mind on a reputable shop or contractor in Adelaide to do the job? Thanx

If I was super keen with a little more cash and knowledge up my sleeve I'd go Dedicated gas setup 100%. Without even thinking twice about it.

Apparently old technology is still used, but theres alot of R&D going on. And I can only imagine this getting stepped up a notch - business would be booming for the guys right now with the amount of conversions going on.

But in higher hp applications, LPG oh yeah. I'm fairly sure theres a LPG driven vlt that is running 10's - But still filling up the tank on cheap as chips LPG.
