Whoa!! Now that is distrubing news! I was under the impression that
Pettit's mixture recommendation was in lieu of the metered oil(there I
go making assumptions again). I did not realize that folks added 2 cycle
oil to their gas AND retained the meter oil. Although, I guess that
makes sense if you are driving an RX-7 hard. In that case, I am
apparently using way too little oil.  Well there goes my seals.  Thanks
Paul [Yaw], I appreciate your bringing this to my attention. Do you have a
recommendation on oil:gasoline mixture ratio for a NON-oil-Meter 13B. I
have seen everything from 80:1 to 200:1

If I had to guess I would say that the Protek R is simply repackaged two
stroke oil.  Cameron at Pettit is a pretty bright guy, but I doubt that
he has the knowledge to discern exactly what is required in a turbo
rotary as opposed to a two stroke.  A chemist he is not.  As for the
recommended mix ratio, keep in mind that it is meant to be added in
addition to the oil that the stock metering pump supplies.
