Royal Purple01154 API-Licensed SAE 15W-40 High Performance Synthetic Motor Oil - 1 Quart Bottle

I use this in my motor scooter (150cc). Seems to work well.I’m not a “motor-head” - so I haven’t noticed anything about performance improvements / enhancements.This brand got good reviews, so I decided to try it. I”m happy with that decision, and will stick with this for future use.

Royal Purple has always been my go to for this grade of oil. Full Synthetic designed primarily for high compression Engines however many bikes use this as well due to the heat load a dirt bike can dig out.

Great product for my 95 Chevy with the 6.5 Turbo Diesel. Usually run it with a quart of Lucas and Wix XP filter. Good for 7,000 miles, most call it liquid gold!

Used in my Onan 4k generator on my toy hauler, seemed to work well, ran often over a week and a half, no issues.

I love royal purple been using it for years but just switched to AMSOIL and am a dealer now, they claim 30,000 miles between oil changes with their oil and filter, WOW. Not to mention the top brand in reputation and in racing.

Very inexpensive for the quality of oil you are getting. I bought 4 quarts for my CBR 600 and it arrived the next day.The only reason that it's not getting 5 stars is because I have noty used it yet. I'm changing my oil today and will give it the 5th star after I've been running it in my bike for a month or so if it meets the expectations Royal Purple has claimed to have set.

Highly recommend this Royal Purple oil. Use it in my diesel truck & tractor and noticed the difference immediately.https://www.amazon.com/dp/B000BRX75M/ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=58275-20&linkId=0b711ce07b58570fd3127ea9fbfeab58

Great product worth the money well spent
