Refrigerant and compressor oil for air conditioning system

I searched this forum and the rest of the Internet, including Suzuki's service manual, for information on which types and quantities of refrigerant fluid and compressor machine oil are needed for Jimny's air conditioning system.

However, the only information I found was that I need R134a type refrigerant fluid (the ubiquitous one). I found that in Suzuki's service manual.

What type of compressor oil do I need?

What are the required quantities of both to fully load the system?


Is the air conditioning system the same in all Jimnys, older and newer, petrol and diesel?
Mine is diesel.

I have just found one Hella's catalogue which lists required quantities of refrigerant and oil for various vehicles' AC systems:

www.autototal.ro/dmdocuments/Catalog%20B...g%20Behr%20Hella.pdf

It lists that Jimny requires between 500 and 600 grams of R134a refrigerant, but 0 ml of oil !?

not sure but I think the oil is simply in the refrigerant (can also put dye in it to show up should there be a leak.

IMO however, from knowledgeable mechanics I have been lead to believe that it's best not to change/recharge the system as experience has shown that once you do, problems start i.e. compressor failure or bursts - could be that the system was about to fail anyway, or maybe the added strain of a newly fully charged system causes failure

anyway ... my compressor seized and failed a few months after a recharge - and to be honest the recharge didn't make the aircon any better than it was in the first place, just hoped it would.

G engine and K (Diesel) charges at 550g
M engine needs only 430g.

STP aircon recharge service or DIY kit offered at Halfords. Charged my Jimny early this year as the refrigerant pressure had dropped below the cut in point preventing the system working. Once charged to the correct pressure its been fine for the last 8 months and is still going strong. The STP solution contains all the system needs ready mixed and also contains a leak sealer.
Will not seal a massive leak, but more than adequate for a slow leak. You can also get the kit on Ebay if you are anti Halfords.
Been loverly and cool all summer

What do you suggest as an alternative to recharging then?
