So i bought oil at autozone and i did the complete change and when filling the new bottles with the old oil i realized 2 of the quarts were 5w30. Now im pissed off! Do i need to do another change because of the weights being different?

Don't worry about it, with the added viscosity in the sump, you are actually doing your engine a favor at wide open throttle in hot climates.

It's not something any oil company is going to recommend doing on purpose, but if the oil was from the same company and is the same type or version, there is not going to be any issue from it being very slightly thicker.

It happens more than you would think.:-D

Your engine is incredibly viscosity tolerant. The normal 5.0 takes a 5w20 and the track pack cars take a 5w-50 with virtually no changes to the engine.

That's 3 viscosity grades heavier!

Loose no sleep over this one.:beer:
