That's a few car re-gases!
R134a isn't used in newer cars (from around 2016); there are now two new refrigerants which have virtually zero CO2 equivalence. Can't even remember the numbers of the gases.
I'm so old, I used to work on a/c in cars which used R22 (which has now been banned for it's ozone depleting nastiness).

Yep 1234YF is the later gas and some hybrid and electric car take a different PAG oil.

And you are really a showing your age with the R22 lol

Happy days; when destroying the ozone layer and helping the 'greenhouse effect' was an everyday part of earning a crust!

Our's isn't used for air-con...but we are actively investigating switching to more environmentally-friendly refrigerants/propellants over the next few years.

It must be for some kind of refrigeration, then! Very popular gas in high temperature fridges (just above feezing). Or is it something else? Interested now when it's bought in 20 tonne flasks!

Kwik Fit will not charge you if they cannot improve the air con, Halfords will do a free check or an air con diagnostic for a reduced price.

For pharmaceutical use (inhalers).

WOW!

I can't believe HFCs are still being used as propellants in this day and age. Goes back to the days when R12 was used in everything from hairspray to paint cans! Even though that was a CFC and is the devil now!

So much for trying to kerb global warming. We are doomed!
