Hi N1KK0 ,
Penrite would be overkill for me ,I would rather use cheaper oil and use that to flush the transmission.
Cheers

Hi Max,
Yes oh I just had it onhand already so $0 cost - notthat I think there's a lot of 85W-140 gear oils around - I did consider flushing with some diesel motor oil I had - but went with the kero in the end - as seems a common choice for tractor users etc thats regarded as effective and relatively safe - didn't have in there too long as didn't want to run risk of damaging the seals etc.
