"I would say their engine runs great on 50:1 without any compromises on the oil that they source...however it seems they are worried about the quality of oil the consumer my obtain hence more oil more safe

The main reason is that the TC

The main reason is that the TCW oil is not rated for the RPM that engine is running. That goes for most of the smaller 2-stroke air-cooled machines.
 
"There is one OIL FOR AIR-COOL

"There is one OIL FOR AIR-COOLED ENGINES.
Air cooled engines run hotter than water cooled outboard-type engines and require a lubricant formulated for their unique lubrication requirements.

Outboard oils have a lower flashing point and tend to burn up early in air-cooled engines, causing carbonization and eventual ring sticking.

Because of this, BIA, TC-W and TC-WII oils can promote the formation of deposits in air cooled engines."
