engine life

it is $8.00 a Gal non-syn outboard oil...I wonder how it holds up to 185 psi and summer 88 degree water riding here in the south...I do not have an extra motor to test it out with...:silly:

Most of us around here use the semi syn Penzoil at Advanced Auto parts for $9.99 a gallon. Been using it for years.
