Usually the difference between oem and the universal off the shelf is the friction modifier. From what i experience is that oem have a lot of modifiers which is why you have the seamlessly smooth shifts. It allows the clutch to slip more. In return it cause more wear and tear on the clutch packs.
Imo for older vehicle with higher mileage, less slip is better if you're trying to prolong it. This is what I achieve with the valvoline. It still have the friction modifier but less allowing quick firmer shifts.
Think of it as you are driving a manual stick shift. If you don't want your passengers to snap their neck, you would graudually release the clutch allowing more slip on the clutch and flywheel. Best of all valvoline is fully synthetic. With WS, it is a secret mystery.
