added 6 oz of seafoam to the oil. It's my daily driver so it'll be close to 300 miles next weekend and I'll change it, unless the oil is black before then.
It's about $7 for 16 oz. You can catch the 20 oz bottles on sale but you gotta buy 2 (autozone). Appears to have cleaned some stuff out. It wasn't as dark last week.
I'll continue doing this before oil changes. 5w-30 Full synthetic Amazon oil. Did some research and the numbers are close to Amsoil. Better than your typical brands believe it or not.
