LOL..."back in the day", when I could only afford a "beater" of a car my buddies and I would toss in a couple of cans of STP Oil Treatment in the crankcase. It solved smoke issue because it was thick like molasses, probably even thicker, like tank oil.....
I'm not suggesting you try it but that STP stuff DID stop the blue smoke in my "beater".
