TO DIRK

http://www.victorymgroup.com/products/aeroshell-oils/ website of a Bangkok based company. They should have Shell Tellus 32 to which you can add your additives. That took me 5 minutes to find on the net.
I just ordered 2 quarts of Aeroshell 560 thru ebay from the U.S. and guess what... they are under way to Thailand. I hope you show these pictures to your reps everywhere as they keep on pushing Aeroshell 500 as the users are convinced it doesn't harm the turbine and is reasonably cheap (penny-wise and pound foolish)
Just got word from your rep in Thailand that he will deliver Kingtech oil, so it can be done after all. Many Thanks.
One more reason to use Kingtech oil would be , your engines run at an average 100 degrees C (EGT source AUG/SEPT 2016 page 70-71 of RCJ magazine) lower than any other on the market with comparable thrust.
As you said :
Our oil is the ONLY oil on the market that was specifically designed to be used in a fuel / oil mix, to be consumed while lubricating the bearings at the TEMPERATURES our engines run at.
