Whenever I mention the oil for the Napier Sabre that also seems to result in a lot of blank looks.
So can the Centaurus and Sabre be safely flown with modern oils?
I've never heard of any engine lubricatiion system using a fish oil additive (not saying some didn't) but Air Atlantique's two DC6s (R2800 engines) definitely had a low percentage fish oil mix in their ADI tanks rather than conventional (60/40?) water methanol.
Edited post: I can't remember if the fish oil was for lubrication or anti-corrosion purposes.
