582 first gearbox oil change
I have just done the first gearbox oil change on my inverted 582 with an E type gearbox.
I am concerned that the oil was blacker, in colour than I expected.
The history.
The engine stood for close to 2 years before being started/used. It was brand new.
The oil change was done a bit later than the recommended 10hrs, but at 15hrs.
The old oil had about the same viscosity as the new oil.
The old oil was as black as the oil from a motor vehicle engine oil change.
Is this normal for the first oil change?
