<DIV>There is a lot of Magnum fuel used on the West Coast with no noticeable difference in bearing life. Most of the people using the OS140 engines have switched to stainless bearings and don't worry about bearing failure after 30-60 flights anymore. The stock bearing failures were occurring regardless of fuel type. The stock bearing appears to be very susceptible to corrosion even if you run the engine dry after flying or not, whether you use after run or not. Stainless bearings made that problem go away and the life of the bearings is typically in excess of 100 flights with most going over 200. I get my stainless bearings for the OS from Jerry Budd at Budd Engineering (aka Rusty Freid ;-).</DIV>

<DIV>YS 4C don't seem to wear out the rear bearings as quickly and we have people out here with over 500 flights on YS engines/bearings with no noticeable wear problems using Magnum. Having said all that, doesn't seem to be a problem out here. Lot of Magnum shipped to the Chicago area, and the Northeast (can't remember exactly where).</DIV>

<DIV>Guys, hope this doesn't launch a tirade of 'this fuel is better, that fuel is better'. Fuel usage is like discussing politics. I run Magnum because I have had very good luck with it, have run it since it was introduced in Denver when I lived there. There are several good fuels out there, I selected Magnum.</DIV>
