Got mine from

Then just type in Mobil DTE Light in the Homepage Search Box.
Current price is $84.00 + shipping for 5 gallon pail. My shipping was about $20.00. It arrived 3 days after I ordered it online via UPS ground.
I have been using it this season in my Wren SS, Artes Rhino, and Jetcat Titan.....about 100 runs on the SS, 75 runs on the Rhino and 25 runs on Titan....zero problems so far. The SS was serviced at about 60 runs for a problem unrelated to the oil. Ron Ballard noted no carbon buildup at that time. I mix it 5% for JC, 3% for SS, and 2.5% for Rhino=====no more organophosphate oils for me.
