I wouldnt use the oil/freon combo to charge with.
Add 3 ounces of oil to the low side then connect the hose, and charge the system.
the system calls for about 26 ounces IIRC, and if you put in 2 cans of freon with oil, your only putting in 22 ounces of freon.
12 ounce can - one ounce of freon is left out in place of the oil.
I only use oil/freon charge when I have a partially charged system that needs a shot to quiet a compressor.
You want to get as close to the proper amount of freon in the system as you can. 2 12 ounce cans woulkd be 24 ounces.
Also the can you showed says leak sealer on it. Not a good Idea. Leak stop can plug up things and kill compressors.
The camry has a pretty well built system, should be able to fix your leaks easy, and all will be good.No need for stop leak.
Fact is stranger than Fiction
