hi all, i asked steve again at SOS, he said use the mobil one & use the lightest weight which im assuming is 5w-30.
since hes the importer im going by him.
You can actually get Mobil One in 5W-20 or 0W-20. Currently using that in my older Gyrodec with the original non-inverted bearing.
Please be careful. Most bearing sleeves are bronze and motor oil, specially hypoid differential oil contains moly disulfide to protect gear teeth during extreme loading conditions. The MoS2 is a sulphur compound and will attack brass and bronze.
If you use an engine oil, a non detergent oil is best.
I would stick with the manuf. recommendations.
my $.02 YMMV
Amen, brother Nick.

I should have been a bit more forceful in directing folks to the link to my bearing faq in the above post, where I mention to stay away from detergent additives.

While experimentation is can be both fun and productive to those so inclined, the golden rule in medicine applies here too - "first, do no harm".

Cheers,

Are there any high quality synthetic motor oils without detergent additives? Anyone know if Royal Purple or Amsoil have additives?
