My 01 F150 has a small leak in the AC system somewhere. Can I just keep recharging it or do I need to take it and get it fixed? The recharge cans don't have oil in them and it's beyond my current skill set to check that.

Any ideas? Thanks

 

There are oil re charge cans. There is also cans with stop leak and cans with florescent dye so you can see where its leaking from..

 

The blue synthetic cans at walmart have oil... look in the ingrediants on the can
