Best oil for 2 stroke, carbed Johnson 115, 120 hours

[rbutterworth]

Was curious as to what is the best oil to use with this engine, carbed, ....omc oil injection, just broken in at 120 hours.....I'm using it quite a bit now on a lake, last two oils were quicksilver and then johnson xd-30...I believe that was the non synthetic.....can you run xd-50 in this engine (carbed with vro type oil injection) or not?....I heard that oil had de-carbonizing agents in it.....any advice welcome.....thanks in advance.

I have a 2005 115 johnson and I run penzoil semi-synthetic with no problems.

Not sure about if the oil is OK, but good idea with preventive measures regarding de-carbonizing agents. In addition to what ever oil or additive you use, also run OMC's "Engine Tuner" at the recommended interval. The can comes with a tube that screws into a port on your intake manifold designed specifically for this purpose and injects the cleaner directly into the engine.
