Seems to have been a rush on this stuff, should be back on the shelf in a couple of weeks.
Bet there wondering why the sudden sales.
Penrite appears to be hard to find and $$. I was thinking about mixing John Deere cornhead grease with 600W (Mobil/Shell 680 gear oil). It seems like this would end up with a consistency similar to Penrite - thicker then 600W, but thinner than JD cornhead grease. Since they are both gear oils, I don't see a problem doing this. Does anyone see a problem with mixing the two gear oils, hopefully to prevent leaking?
