ac oil question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I replaced everything on the ac and put in 8oz of pag oil in the AC system and had it filled at a shop and it cools really cold air.

Then it started a couple of days later and a little warmer outside to make a shuddering noise and did not cool. After a while it stopped shuddering and was really cold again.

Is this because there is not enough oil in the compressor because I read it was to have 11 oz of oil. If so, can oil be added without the system being opened again? Or what other problem could this be? 2002 Tahoe
