The manual says to use Hypoid gear oil SAE 80 which is a GL5 oil. Ive read suggestions on GL1800 Tech Board to change to Mobile 1 synthetic 75W90. My concern is that the GL5 75W90 lubricants state they are for Limited Slip (LS) differentials. After searching the web for more info on this, I can not determine if these synthetic gear lubes contain an additive for the LS Diff or not?
I do not want an LS additive in my wing.
I've found a GL5 75W90 full synthetic gear oil by Castrol marketed for outboard motor foots. It does not have the LS designation, although I suspect it is the same oil as they market for differentials.
Anyone have any info on this? :?:
