Mixing synthetic blend two-cycle oil and non-synthetic oil
I have a 1994 60HP Johnson outboard motor. It's a 2-stroke engine with an oil injection reservoir. I've been using non-synthetic Evinrude/Johnson 2 stroke outboard oil that meets (or exceeds) the TCW-3 standards. I've seen the Evinrude Ficht RAM injection synthetic blend 2 cycle oil and have heard that it's a cleaner oil that leaves less carbon deposits in the cylinders. First of all, is it really a better oil to be using? If so and I start using this new synthetic blend oil, do I have to empty the non-synthetic oil from the oil injection reservoir or can I add it to the non-synthetic oil already in the reservoir?
Re: Mixing synthetic blend two-cycle oil and non-synthetic oil
The FICHT Ram synthetic blend oil will mix OK with any other TC-W3 lube. You will find that it smokes less and that you will have a cleaner running motor. Let your oil tank get close to empty, then add the new oil to it.
