I know I should be over in the 1200 section, but there's more here seen inside a gearbox 
Changed my gearbox oil today on the HP and the old oil came out red
I've been using Halfords Part Synth GL5 75W-90 every 5 to 10,000 (this one at 8,000) which is a clear colour and it's never come out red before.
I seem to remember reading about a bearing seal causing discolouration of the oil when it got chewed up.
Done a search and can't find it (Edit - on here, not in the gearbox).
What do you think?
Cheers
