So I was talking to my neighbor about his car. It was some kind of mid 80s Nissan that looked in excellent shape. I constanlty see this guy changing oil and always working on it. Basically, he told me that the only reason its still running today is because he has used nothing but Syntec at 2500 OCI. He asked me what I was running and told him I put in some Quaker State Ultimate Durability and he said, "You have to get that oil outta your car immediately, it's gonna sludge up like crazy!. You see, I'm not a mechanic but have worked on several people's cars throughout the years and as soon as I pop open that valve cover and see the sludge, I ask the owner what oil they're using and 99% of the time its quaker state." I just responded with an "ok, ill do it when i can."
But anwyways, I didn't feel like arguing with him especially since he changes out syn at 2500mi OCI's.
