Have just obtained my airworthiness certificate on my Kelly D that has a Rotec R3600 installed. My questions relate to the oil that is being used by those of you that have this engine. I initially installed Mobil 1 15w50 fully synthetic but just changed to Castrol 4T 20w50 motorcycle oil -- which is a natural oil. Only had a little over 4 hours taxi time on the engine and made the change because of what I read from Rotec that the PSRU gears needed the additive which is in the motorcycle oil. Saw my oil pressure go from 60psi with the Mobil 1 to 30psi with the Castrol. My only explanation is that the Castrol was foaming. Only have ran the engine 30 minutes with the Castrol. What are you guys using in the engine and what kind of oil pressures are you seeing? Any comments would be appreciated.
Thanks, Stan
