I think it will still flow some oil even in the "full off" throttle position on the metering pump. Since I also add two-stroke to the oil, it isn't really an issue for me, but if someone is depending on the oil injection system only, they should definitely verify it works. My stuff is mostly vintage 1986. Perry Hmmm... this is all very interesting and has possibly shed some light on issues that I've had. In the beginning I had made a linkage for my throttle to oil injection lever that operated from 1/4 open to 3/4 open (or so I thought) but I seemed to use more oil than expected. I began to add premix to the fuel while I experimented with the linkage to reduce the flow finally removing the linkage entirely. I thought that it was now at minimum flow, but I still only had 3-4 hours flight time before the low oil level light would begin to flicker. Since I have up to ~12 hours of fuel capacity, this wasn't really ideal. I've just removed the entire oil injection system in order to check oil consumption as I'm suspecting that I may be burning some oil in my turbo. But it could be that I was simply increasing my oil flow rather than decreasing it. As soon as this kid shows up, (or soon after) I'll get out for a long flight again to check this, but in the meantime I'll closely inspect the metering pump tonight after work.
