(I think that fuel with oil in it would have a different viscosity index than fuel without oil in it). You just have to monitor the thickness of the fuel. If it falls below a set parameter it would send a signal to a solenoid that would switch a valve to a different tank filled with premix in it and sound an alarm. The problem of course is writting the program. The rest is just basic mechanical stuff.

Personally that is to overdone for me. It only takes a few extra minutes to use a mixing bottle and KNOW the oil is in it. Unfortunately for the DFI guys, this won't work.

I have figured out a way using one pump and the remote tank. Without all the computer stuff. And it is stupid simple. If i had the pump, I can build a prototype with a trip to westmarine.

The factory MERC system works with just one pump, and the module is for nothing but a warning system and doesn't affect the oil injection system in any way.

I was referring to my "automix unit" idea and Destroyers post.

I don't know about all the tech stuff.......but I'd speculated that a new 2012 Opti 225 prop'd just right, and trimmed out will push a clean V21 to about 55 mph, maybe a touch more.

Electric oil injection unit arrived today from Go2Marine. Nicely packaged, looks well made. Will try hooking it up tomorrow if time permits and report on how it works.
