So he mixed 50:1 in the gas AND put oil in the oil reservoir. What are yalls thoughts on this? Isn't it too much oil? What if I just always mixed 50:1 and said to heck with the oil reservoir? Is that a bad idea? If I just went with mixing my own, what do I do with the oil reservoir? Thanks ahead of time...
Doing both is definitely way too much oil. It will lead to more carbon build up than under normal conditions and premature fouling of spark plugs.

If you are not willing to trust the oil pump then just mix 50:1 yourself. As far as the oil pump, I would think that all that you need to do is disable the alarm and simply not put oil in it---again only if you pre-mix!

One more thing I recommend is the use of "carbon guard". I add it to to every tank of fuel, that and stabilizer

Knock on wood---I have a 1982 Johnson 60 hp and she is still running strong! This motor pre-dates oil injection, VRO, etc; however, I have a 90 hp Merc on my pontoon boat and I am afraid of this oilinjection stuff too, but, it is supposed to give an alarm if no oil is pumping.

Good luck to you!
