Blowby Combo Pack (Tune Up and Oil Stabilizer)
This combination of products will reduce or repair blow by in higher mileage vehicles caused by piston ring sludge, worn rings, or stuck rings caused by hard carbon. Before oil change, use the Tune Up in the crankcase (where the oil goes) and idle for at least 20 minutes. Add the Oil Stabilizer to the new oil at oil change. Please follow all instructions.

Gave this a shot and it completely exceeded my expectations. It did a fantastic job clearing out the system and getting everything running smoothly. If you're on the fence about trying it, just do it. It works!
Excellent, will be buying this again, it actually does what it says it will, imagine that:)
