This is a great oil I have ran this for many years and never have had issues. The price is fantastic as this is a great value. Every oil change the oil is clean at 5,000 mile oil change intervals. There is a noticeable fuel economy difference. Castro will keep your engine running smooth for a very long time. Read more
