Super EZ Automatic
The Super EZ Automatic has an automatic oiler. On mine, it doesn't seem to pump much oil on its own, but the chain seems to get enough lubrication without pressing the manual oiler plunger. Nevertheless, I usually give it a shot at the start of each cut. The ground rule is that you should use about one tank of bar oil per tank of gasoline/oil mix.
I don't remember what the recommended gas/oil mix is supposed to be, but conventional wisdom is that with the newer oils, you can go with what the oil is rated for, e.g., 50:1 for most of them. However, since I wear both suspenders and a belt, I go with 32:1 on all my older two-cycle stroke engines. They all seem to be holding up well. BTW, I got mine second hand also and it had one of those safety chains with the extra anti-kickback tabs between each pair of cutters. It was very slow cutting until I ground off all of those tabs, and now it acts like a real chain saw. Gene Gauss
