Royal Purple has always been my 1st choice of oil for all my cars and smaller engines.With proper regular maintenance this oil increases the life of your engine while also keeping it clean! Engines also run smoother .I highly recommend Royal Purple. I would give it a 6 star review if I could, But then I'm just a hardcore fan of Royal Purple. ;pMy order arrived swiftly. Thanks :o)
