LPG quality and economy

Do you have any idea what the difference between the gas from Shell and Supa Gas are Jim?

Cheers Krakka

Jim, do you know what the local 'official' definition of propane is ?
In NZ any thing over 90% can be called propane.

Each tanker load has a document that gives the makeup proportions and I sometimes ask what the current load is when I fill my 45kg tanks. In some areas where it can get very cold the suppliers make sure that they deliver 'propane', in other areas they just deliver 'lpg'. Where I get my bulk supplies we sometimes get a tanker that has left over load from delivery to an area that gets very cold so we do sometimes get a high propane content. The 'normal' high butane content lpg gives a very low flame on a cold day.

the supagas in SA fills their BBQ bottles from the same tank so i would suggest it is propane

G'day Jim,

Not sure about the difference between SupaGas and Shell LPG but I have a similar story with Shell LPG and Safeway/Woolworths LPG.

I consistently get at least 10% more distance out of a Shell fill than a Safeway LPG fill.

Anyone notice this.

Regards,

Bruce

Hey Jim,

I was actually speaking about this with the Caltex guys at the refinery a while back, and they said to make sure to use the propane/butane mix if possible. Gives around 6% better milage than the straight propane.

So yes if the tanker also fills the bottles, then expect less ks per fill.

I also did similar tests regarding supagas and my local shell and had similar results.

Interesting post Jim.

I found this: LPG standard

The variation in economy you would think is deserving of more consumer information at the point of sale... if the weight of your loaf of bread varied by that much it would have to say it.
