Ok, so I just picked up and installed a new powerhead and I wanted to be sure the oil injection is working. to my understanding the safe way to do this is to run 50-1 mix and check to see how much oil is being used from the tank.
This is an early 90's yamaha 30hp 3 cyl.
I have checked the screen and made sure its clean.

Any ideas on how much oil I should be using on a 5 gal tank?
