That sounds like a good answer. The engines were a little fat on top and smoking good but not excessively. The LSN on both engines were maybe a touch leaner than I would normaly run on a 10 tank engine but they would still load up just slightly sitting at an idle.

I used to run 10% oil sidewinder fuel but I seemed to me that the engines were showing wear earlier. The crank pins all seemed to show wear first, then the P/S didn't seem to last as long. So, I switched back to 12% oil and have had good results so far.
