that oil seemed to do okay in comparison to your others and pretty cheap, did your clutch actuation point hold well?

you can tell when the oil is worn out because the clutch starts grabbing. this oil is cheap enough to change very very frequent. it is also available darn near everywhere. it has a decent price vs performance rating.
