Does 40 to 1 have more oil than 50 to 1?

A 40:1 oil mix ratio means 40 units of gas for a single unit of oil drop. Likewise, in a 50:1 gasoline, there are 50 units of gas. So, a 40:1 oil mix is denser and lubricates better than 50:1.

What happens if you put too much oil in 2 stroke?

Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power. While not ideal, these issues can be fixed by simply replacing the fuel in the tank with properly mixed fuel. But running a two-cycle engine with too little oil can actually destroy the unit.

What is special about 2 stroke oil?
