Bad Rings

[Aaron]

Hi all,     I hope some one can help me out here. I purchased 2764H about a year and a half ago and just pull my second jug. Both times I experienced a loss of compresion in the affected cylinder. When I pulled the cylinder I found my rings busted into several pieces. I've been burning mostly premium auto gas with an occasional tank of 80 avgas. I've been using Aero shell 15W50 semi synthetic oil. The cylinders in question were #2 and #3. With #3 I was also sending alot of oil out the exhaust, but #2 didn't seem to have much affect. What I'm wondering is, has any body else had this problem with the rings, and what might I do to prevent it in the future?                         Thanks in Advance                                 Aaron Hutchinson                                     2764H                                         RMY
