I wish my missus was as useful at DIY.

I would be sending mine out to do 95% of my jobs if this were the case

Could you use car refrigerant to charge or top up the system?

Cars are R134a generally. Splits are 410a or R32 more popular now as lower gwp. It's all very expensive now though!!

I think the Yanks are now using the new generation R1234yf which is a semi flammable floropropene gas in their auto air conditioners. Because it's semi flammable this new gas will only be available for purchase if you have an FGas license.

yes, its all getting difficult in the world of a/c. Good old R410 is now super expensive, R32 is so flammable that the MI's to install it have to be read very carefully wrt volume of gas in system vs volume of rooms(s) being served. I was going to install r32 into a small server room but when doing the calcs i would have needed both detection and ventilation systems installed which would have added considerably to the cost. Pressures are going higher yet the method of connection, i.e. hand flaring has not changed, i see many more leaks in the future.
