does anyone know how many grams of r134a a/c gas a jb starion holds? i think it is slightly higher or less then r12.

Starions dont take 134a unless its converted. What they do take is HR12, this is the new gas that works directly with the R12 system.

It's converted. can anyone help. just have a quick check under your bonnets and see if the stickers still there with grams figure.

maaaaate.....
Ok, i will check it out just for you...
However, when i used to fill cars with this gas it was a given grammage and then i would add tiny bits at a time by pulsing the filling station by points of a gram until the sight glass on the receiver drier (filter) was clear. We were the first to use it on cars in the country, we were also the founders of the problems with this gas and the very smart mo fo's who discovered HR12 as a much better replacement. By that time the manufacturers had gone the other way and now no one gives a shit... except Boral who purchased the rights from us and now is the Australian distributor.

r134 charge should be about 85% of r12 charge

I have a JA (not sure if its the same system)

Had my refrigerant changed a while back at profix, they used boral er-12 refrigerant and recorded the quantity as 195 (dosnt specify grams or units of measurment though) on the sticker

hope this helps (somehow)

HR12 is an environmentally friendly hydrocarbon refrigerant and should be charged at about one third of the quantity of the R12 refrigerant charge ( not kidding ) yes it is flammable ( who cares ) but the amount is so miniscule that there is probably more chance of a fire under the bonnet with a packet of matches and a petrol doused piece of newspaper.
The hydrocarbon molecules are also mich bigger than the synthetic flurocarbon or hydroflurocarbon molecules in R134a and on top of this the gas is one hundred percent compatable with the mineral oil that will be in the system. DONT use 134a unless you flush the whole system completely and change the dryer and add synthetic oil. SP34E refrigerant is Flurocarbon based and compatible with mineral oil so it can be dropped straight in but can be hard to obtain in a small quantity. HR12 is hard to obtain but its the go as its refrigerant properties are better than the good old R12 and is less likely to leak as discussed when it comes to the molecular structure
