Well had a cracking holiday flying among other things in Thailand. Flew the K60G with serial number 355 for over an hour on Shell Vpower diesel and Aeroshell 560. No problems whatsoever. The rep in Thailand claims he has Kingtech oil but apparently only for the happy few. No calls were answered, he actually blocked my number as he is of the opinion that in an internet era the customer should only ask info directly from him and not on a forum. I tried emailing and LINE. No answers or blocked. With reps like that.... Anyway I am very pleased with the K60G and would buy locally more but with this rep I see myself going for other brands. I will check the turbine in myself to the factory in Taiwan when it has it's hours for a cleanup.
