Directly from my several contacts at Mercury....they have all told me to buy/run QuickSilver Premium Plus oil. It's the same as the Opti Oil just packaged differently so they can sell it to marina's and big box stores as a premium 2 stroke oil. You can easily buy this at places like Walmart, Bass Pro, Cabelas, etc...it's usually around $28 a gallon.
Again, simply NOT true.
Look at the Opti oil(Brownish) and look at the Premium Plus( Blue), and different viscosity. Definitely not the same oil.
From an email that was sent by Mercury Marine a few years ago
Effective October 2010, Mercury OptiMax / DFI or Quicksilver DFI 2-Cycle engine oil is the recommended oil for all OptiMax models - including Pro XS. (The previous recommendation stated the use of Mercury Premium Plus 2-Cycle Outboard Oil in ProXS models and OptiMax oil in non-ProXS models.)
OptiMax / DFI oil is a superior oil when compared to the Premium Plus oil. While both products are high quality 2-cycle engine oils suitable for use in OptiMax engines, the OptiMax / DFI oil contains a higher percentage of additives that reduce carbon deposit formation. blah blah blah.
Now, I know a few people that have used Premium Plus in their Opti's, and never had any problems.
As I said above, you can go to a dealer that sells bulk, and save a lot over buying by the jug. |
