white smoke at startup (2-3 mins only)

I first did a quick kerosene flush by adding it to the old motor oil and running it for a quick 2-3 minutes....then drained everything. I ran the AEROSHELL for 2000 miles...changed it. I added Marvel to the new oil...since I live near and am friends with a lot of Grumman aircraft mechanics they schooled me in many things about our types of motors and what they like...I even have a WW2 AC mechanic at my logde who says never baby your aircooled motor..just keep em well lubed and warm. He is a character.

What you felt from the Seafoam was the aeromatic hydrocarbons and naptha adding energy to the fuel stream. As far as running 50wt aeroshell in your car, at least you will get to experience a new motor sooner. The lack of lubrication at startup will accelerate the wear due to insufficient lubrication caused by the increased viscosity at startup. Adding Marvel Mystery Oil is just that a mystery, the single best thing you can do is supply your motor with clean, proper temp oil, at the proper viscosity, from a quality manufacturer. There is a reason that aircraft engines and auto engines use different oil, If you ran a 911 motor at 75% continuously it you would need to be on the Autobahn at triple digit speeds. BTW, I am also an A&P mechanic with more than 30 years working on piston engines, round and flat. Go to SAE International, grab a membership and read to your hearts content, more written about motor oil than you can read in a lifetime, I know I am trying. BTW the Porsche PFM was recalled by Porsche, liability tail was too long. Porsche Aircraft Engine P F M 3200

I ferried a couple of these, cool single power lever, advanced for the time.

If it is just white, it's water.

HxCx + O2 = CO2 + H2O

that is how it works

That would be for burning oil, the bulk would be heated oil in the exhaust. Planes that use smoke for skywriting use mineral oil injected into the exhaust.
