How much Sea Foam Motor Treatment should I add to my oil crankcase? [SOLVED]

I accidentally confused the instructions on the Sea Foam bottle with another product. I added the entire bottle to my crankcase oil port. I haven’t started the vehicle. Should I change the oil immediately? Or should I run the engine a few minutes first? 2009 Chevy Silverado 1500 5.3 Liter.

Hey Jonathan. You understand that adding 16 ounces of Sea Foam to 6 quarts of engine oil. Though you doubled the recommendation, you may operate as normal while you keep an eye on your oil color. If it goes black fast (check after 20 miles), change the oil. We can also appreciate that you might want to go ahead and change the oil for peace of mind.
