Due to the recent number of premature bearing replacements required we have decided to prohibit the use of Aeroshell 500. The amount of contamination in the bearing and chamber has been directly and consistently linked to the use of this oil in KingTech engines and as far as we know, KingTech engines only.

If you must use turbine oil in order to be compatible with the rest of your fleet, please use BP 2380 or Mobile Jet II, basically anything but Aeroshell 500, otherwise, please look into KingTech blend which is non carcinogenic and proven to have the best results in lubrication and reliability of our engines.
