Just an idle query really......
Manual says change gearbox oil every 6,000 miles. I left mine go at least 12,000 miles and was very surprised to see how clean the oil was when I drained it.......any thoughts on how often it really needs to be changed?

Re: Gearbox Oil Change
Modern oils are very different from those available when the manual was written. However, for a Minor you should still be using a fairly low-spec 20/50 multigrade that is similar to the old style ones, so I would still go with 6,000 - do it at the same time as you do the engine oil.

Re: Gearbox Oil Change
less moving parts in a gearbox. this will be why the oil retains its colour longer.
I change mine every 3 years along with the axle oil and coolant.
I do about 2500 miles a year.

Re: Gearbox Oil Change
Engine oil discolours because of the by-products of combustion, such as carbon, getting into it past the rings. Gearbox oil doesn't have to deal with this, so doesn't discolour in th same way.ampwhu wrote:less moving parts in a gearbox. this will be why the oil retains its colour longer.

Re: Gearbox Oil Change
Used gearbox oil is also a good rust preventative as it has no acidic contaminants that are in used engine oil.

Re: Gearbox Oil Change
Quite right tricky, mix a bit of paraffin with it and brush or squirt it on the underside if not already protected
