Craig,
Here is a web site for information
http://www.mobil.com/USA-English/Lub..._DTE_Named.asp
Also, there has been a couple very good threads about it here at RCUniverse. Do a search here to read up on it.
It was the information in these threads that caused me to switch over. Check the threads out. There is a lot of very good information in them and guys that have been using it in their turbines talk about it.
The cheaper price is nice but I believe it to be a lot better for the enviornment and for us physically.
