The extractor is the problem. Rather, lazy fucks using the extractor. It doesn’t get all the oil out. It can leave 50-600ml behind. Clearly dude didn’t suck all the oil out of the engine. He probably threw 6 qts in there and called it a day.
With the extractor. You gotta toss in 5 and a half quarts. Let the motor run at least 5 minutes. Turn it off. Wait a minute or two. Then measure and add if needed.
