Too soon to give you a hard number, as I'm still on my first full tank of gas since doing the mod. So far the level in the tank has dropped ~1/4 inches or so below the molded fill line on the tank that I topped it off to, after covering about 150 miles.

Since this mod just provides a different oil source to the OMP, the expectation is it will consume premix at the same rate that the stock system did, roughly 1 quart per 1000 miles. More if the car is flogged hard, less if just cruising around.

Another thing to add - if you do this mod, it's a good idea to also run some premix in the gas tank for at least the 1st tank of gas post-mod. It will take a couple of miles of driving (<10) for the system to "prime" itself, and for the premix to reach each of the injectors. One good thing about the stock lines is you can see the color change and know it works when you do this - color in the lines changes from the honey color of crankcase motor oil to the color of the premix (the stuff I got is blue).

That's cool, thx. Might not be a problem on a rotary but I would wonder if the vibration from being mounted on the engine couldnt cause frothing in the oil.

Using a snowmobile oil tank with a level sensor and putting an LED in the cluster next to the fuel gauge would make it almost OEM.
