Zitat:

For most of the airplanes we manage, we recommend AeroShell W100 with a pint of CamGuard added at each oil change. That’s what I use in my airplane, and my two engines are at nearly 200 percent of time between overhauls (TBO) and still going strong. For wintertime operations in cold climates, I recommend Phillips X/C 20W-50 multigrade with a pint of CamGuard.
