Anyone ever had any experiences with this? Personally i wouldn't trust this very much... it may seize or get loose or something as well.
Well said, this product is useless in my opinion.The manual says you only need to change your oil every 7500 miles - Synthetic oil is usually guaranteed for at least 12,000 miles so you could safely run 10k between changes for normal everyday use so this would seem to be superfluous, besides - who needs the added cost/complexity?
