Quick Silver DFI is not the same Quick Silver Premium plus garbage you're talking about.

Fine if you're using Quick Silver in your Opti. Personally my OWNERS MANUAL for my opti states.......Mercury DFI, Quick Silver DFI. It says I can use Premium Plus.....IF the others are not available.

You can pour the oils out into a cup and SEE the viscosity differences. If you think the stuff is the same, fine........it is NOT.

I use premium plus in my old 7.5 and 9.9 hp 2 cycle motors. The OPTI DFI is not even close to premium plus.

The guy ASKED where to get DFI, I told him.
