OK, so tell me all about LPG!

What is it / why is it so cheap?

Is it mixed with petrol or is it a case of petrol OR LPG?

What's "multi-point" and is it good/best? What's wrong with non "multi-point"?

Does LPG affect engine power or fuel consumption?

Anything else worth knowing about LPG?

LPG is great.
It means we can afford to run V8's  :lol:

It's cheap because its a waste product of petrol production and tax is less cos its a greener fuel.

Multi point is better than single point as you dont suffer any power loss if its set up right. It is more expensive to fit though.

Single point there is a slight power drop from petrol, but not too bad tbh. Consumption is a bit worse but at 40pence a litre you cant really complain!

I've got 1 LPG rangie, an LPG 110 and an LPG vectra...and my other rangie is being converted when i get round to it....  :D

LPG burns slower than petrol (burns hotter too I think, anyone confirm?), so adjustment to the ignition timing is recommended.  You can either have it run rough on gas and have it run fine on petrol, or fine on gas and rough on petrol or a comprimise between the petrol and gas running states.  This of course largely applies to just manually timed engines.  No idea how engines like the EFi units handle it.

LPG is liquid petroleum gas and is a by product of petrol refining
It is so cheap cos the government don't tax it to the hilt ( yet ) as it's a cleaner burning and therefore greener fuel source
It is not mixed with petrol - you either run on gas or petrol fed to the engine from seperate tanks - this is usually a simple flick of a switch on the dash
multi pont is like fuel injection and is almost a must have for injected V8's for them to run properly - carb fed engines are more than happy with a single feed to each bank of cylinders via the inlet manifolds
engine power will be slightly down but to be honest not noticeable on a V8
fuel consumption will also be down a bit

Lpg can also be used on diesel engines but this is a mixture of diesel/gas at a ratio of about 10% gas AFAIK
I have had two V8's running on gas - a 110 3.9 V8 running on SU's and a 3.5  V8 Disco running a multi point injection system
Both ran really well and I maintain that V8's are even smoother on gas if set up correctly
V8 power and diesel equivalent economy - can't go wrong really
That's my humble opinion anyway

How "available" is LPG, nationwide? How about Europe?
