I have been use DTE Light 32 at 5% dilution most of last season and this season in a P-70, Wren 54SS, AMT NL Pegasus, P-180, Rhino, Titan, and recently, my new Wren 160, now with 35 uneventful runs on my Kingcat. Zero bearing problems with over 250 flights on all these motors combined. None of the motors has been sent in for overhaul, so I have no way of knowing whether coking deposits are a problem, but the fact that all the motors are running fine, I rather doubt it. Another club member has been using it for many flights on his Wren 44 and 54 and RAM 500.

I see where price has gone up a bit. A couple of us got together and bought 6 pails about 1 year ago for $76.00/5gallon pail dropped shipped to one of the guys place of business, so about $3.80/qt.
