I'm not sure which forum my questions fits best, but since (I think) AeroShell finishes their general aviation oils in the U.K., I picked this forum.
1. Does anyone know the rough base stock make-up of the AeroShell Diesel Ultra aviation oil for aviation diesel engines? %PAO, %AN?
2. If/when the oil is also used as a heat transfer medium (as is in most aviation piston engines via the oil squirts under the piston), which base stock (PAO or AN) makes the most sense? Is resistance to coking the biggest concern? Are there significant differences in the heat capacity of either base stock?
Thanks in advance for your comments.
