This synthetic oil is great!! It provides much better lubrication for my 2018 Can-Am Spyder RT Limited SE-6 with the 1330cc ACE engine than the XPS stuff than the manufacturer suggests. After changing to this oil from the XPS garbage, my engine runs quieter, cooler, and shifts more gently. I will stick with this oil!!! Plus it's cheaper than the XPs stuff and I can order it directly.
Very fast delivery i got a sticker for the tool box which every good mechanic loves product was exactly as specified and very reasonable price highly recommend
Bottom Line
Yes, I would recommend this to a friend.

Best oil for Powersports

I use this oil in all my Sportbikes and dirtbikes and have for 14 years. I wouldn't dream of using anything else in them. The motors run quiet the clutch performance flawless. No slipping when I change the oil there's no sediment in the oil from the clutch pads like you will see with other oils. This oil doesn't foam up like other oils do in the high rpm engines. The oil stays where the work is being done and keeps the parts lubricated throughout its lifecycle.
