2 yr old oil IS OLD Oil, be it 1 mile or 1,000 on it, that's also why when you get your car truck changed, it says 3,000 miles or 3 months what ever comes first LOL
YES 3 months might be over kill
BUT, in vehicles that see temp changes, condensation can build up IN a motor, and thats kinda why they suggest changing it, even if low miles
oil that looks dark, generally is time to replace
before adjusting your clutch change the oil and see, BUT even if you adjust before that, it won't do anything BUT maybe help.
as again its a pretty simple deal
never hurts to check it!
