What kind of oil do I use for the rear axle? It was cleaned and now needs to be lubed again but not sure what to use.

Thanks

Hi,
Little idea what to say with so little info. Rider or walk behind? Gear or hydro? Gear units use a special grease, Havoline or other sythetic will do, blue or red. Hydros now will work with 10W30, but age matters.
Peace,
Clarke
