I have a leftover supply of special Optimax 2 stroke oil and would like to know if there would be any harm in using this modern mixture to run 1990 Merc 175's which have always used Merc Quicksilver mix.
Any advice much appreciated.

In a DFI engine the oil does not get mixed with the fuel as in Carb or EFI engine. I would think that DFI oil may not mix as TC-W3 does.

This is from Mercury Website.

Mercury Optimax/DFI 2-Cycle Outboard Oil

This new synthetic blend oil was developed specifically for the greater demands of DFI outboard engines. Higher operating temperatures combined with reduced oiling rates have put increased demands on the lubricants. This exclusive new formula provides increased lubricity while minimizing carbon deposits, helps reduce smoke and provides the highest protection for the engine. Not intended to be used in all applications specifying a TC-W3 oil.

Thanks for the advice - I don't think I'll risk it.

Weird.....I thought what was good for the Goose was good for the Gander. Many people run ficht oil in regular engines....if they want to spend $25/gallon.

Optimax oil is a synthetic blend, I would see no harm in blending it with regular TCW-3. Ask your dealer.

I just spoke to my BW /Merc dealer.
He said ABSOLUTELY DO NOT mix the synthetic Optimax oil because it is meant to be injected under pressure - and, BTW, he offered to trade me back into the oil I need.
Thanks for all your help.

The Opti oil does not have the mixing agent added.
Because as was said before the oil does not have to
mix with the gas.
