Ron, nothing you list does anything except lighten your wallet. As bloom says, the so-called oil stabilizer (has anyone ever seen unstable oil?) mainly just thickens oil, and as he says, the clearances in the engine require the oil viscosity the engineers designed the engine for, 5W-30 in our 2.5L turbocharged engines. (Clearances are the space designed for lube to flow. Tolerances are allowable error.) There is no need for upper cylinder lubricant.* Water Wetter is great to reduce the surface tension of water (so it wets better) in race engines that don't allow slippery antifreeze that can leak onto the track. All antifreeze-coolants already contain just the right amount of surfactant to reduce surface tension.
If you want better oil, buy better oil. None of us can home-brew oil better than the oil company chemists can make to meet a price point. Red Line oil might be better than Mobil 1 or Pennzoil Platinum or Castrol Edge...or maybe just equally excellent.
*I used to operate and maintain big diesel engines. We used an upper cylinder lubricant, a 50 wt oil of very high alkalinity injected directly into the sides of the liners. Of course, we were using heavy black fuel oil with 3% sulfur in that 57,500 hp engine (straight 12 2-stroke, 95 rpm red line) and consumed about a ton a day of this lube oil (the crankcase has 30 wt oil). Our car engines are different. No need for upper cylinder oil. I've put over 200,000 miles on a couple of cars with no significant cylinder or ring wear and no upper cylinder lube added.
