So i did my Supercharger oil and filled it to the bottom of the threads and used about 6 ounces I'd say. Sound correct? I'm guessing i didn't get all the old oil out completely but I spent an hour and kept going until I couldnt get anymore out and filled it until the threads. Maybe its all in my head but I think its running better PSI now? Lol any adivce on if i did it correctly or not would help as I worry a lot lol

 

Sounds about right.. Did the old oil stink? My old oil smelled bad..

 

It was a medium browinsh color and it stunk pretty badly.
