LPG differences?

I normally fill my straight gas 351 with lpg from a shell servo, but I just filled at a BP and noticed a almost immediate difference in how the car ran. On the BP it has a considerable power/torque increase which feels like it could be at least 10%. Anyone else noticed anything similar?

you will find differing companys add more or less propane into themix which is whats vaailible nationally dependent , see if the next one feels the same .

Re: LPG differences?

i have noticeddifferances in performance in my dedicated lpg BA .

i mostly fill up at the local caltex

but i have noticed if i fill up at some of the " discount shops " such as matilda or woollworths, the car is harder to start , when it starts sometimes it will miss and sound like it is running on 3 cylinders , run on when i turn the key off and generaly not perform like it should.

i try make sure i dont need to go to these places anymore.

i have not used shell or bp much for ages.

the caltex is just more convieniant.

Re: LPG differences?

G'day,
as atec suggests, there is a difference in the Mix.

There is 2 types of LPG. Propane, and Car Gas.
Propane is just that....100% propane.

Car gas is a Propane/Butane Mix. The ratio can be as high as 60/40% Your car will run better on propane, than car gas....even better if tuned for propane.

It is this discrepancay that introduces air box explosions and the like.

It makes no difference on oil company for this, simply what has been supplied to your servo.
Cheers
Jas

Re: LPG differences?

LPG is composed of a mixture of gases, and is made generally to a spec HD5, however this always quite a wide range of poprtions of propane to butane.
this changes the octane rating of the fuel and it heating value slighty.
propane has higher octane butane has higher HHV.
Thats why you will find variations.

Re: LPG differences?

you will find that the more you run on gas the better she will run. But like petrol, gas must be different depend on the company we all find a petrol the our cars run better on. With me it's BP for petrol with my 302, do they supply some cheaper independs servo's, I've noticed Caltex does.
