Is there any problem with slightly overfilling a system.

I installed a VintageAir system that has 4oz factory fill but I had some crimp fittings that wouldn't hold pressure and I lost a small amount, probably less than an ounce.

The system holds 28oz of 134 so I have 2 12oz cans and a 2oz can that has 2oz of oil as well.

Any harm in an extra 1.5oz or so oil in the system?
