HI Bob,
I use Mobil Jet II turbine oil as an after run / long term storage inhibiting oil. I also use it in my metal tanks to stop them from corroding in between contests.
This has been tested and is used regularly by (multi class) AMA speed record holder Jerry Rocha of Napa, CA. Jerry is the highest performing and most consistently fast speed
flier (in many different classes) that I've ever known. Jerry regularly wins the NATS and often on his first flight of the day.
The late Greg Settles told me he used 1/2% in his unlimited nitro fuel which he found to lower his cyl. head temp by 50 degrees. I forgot to ask him if that made him go any faster.
It is a bit of extra work to flush out my tanks before every contest, but not that big of a deal. (Contests being less & less these days)
I do note that this turbine oil contains Tricresyl Phosphate which is not recommended to be on exposed skin, so a level of caution (gloves) should be exercised if using this oil to prevent direct contact with your skin. That being said I have been around this product for 40 years servicing jet engines (almost daily), and with a modicum of care have not experienced any health issues from being exposed to it. MJ II must be a good product (at least in turbine engines) as it's used in the airline industry all over the world.
I hope this is of some value.
Merry Christmas
Paul
