Seeing as I was just asking in a previous thread about your favorite brand of oil. I got really curious about oil additives. Have you ever used it? Do you like it? Does it actually make a difference? So many questions......lol
I used it before.....made my oil too thin. I started hearing a knock in my engine so I did an oil change with fresh oil and the knock went away. Never gonna use it again. Not worth the risk of damaging your motor.
