Royal Purple HPS Series motor oil is specifically formulated to maximize performance and meet the demands of high performance and modified engines. It is fortified with a high level of zinc/phosphorus anti-wear additive and Royal Purples proprietary Synerlec additive technology. This unique blend enables HPS to outperform leading synthetics and conventional lubricants. The available viscosities include 5W-20, 5W-30, 10W-30, 10W-40 and 20W-50. HPS is recommended for vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection. Royal Purples HPS Series of motor oil responds to increased pressure with increased viscosity. Its advanced additive technologies, such as Synerlec improves the condition of metal-to-metal contact under severe conditions for greater protection.
After using this Royal Purple oil, I was hoping for significant improvements, but noticed no real difference in performance. It’s okay, but I expected more for the price. I’ll be trying a different brand next time.

Good oil, but the packaging was damaged
The oil itself seems to be doing its job well, but I received my quart with a dented can. Not a huge deal, but it made me a little wary about it being a fresh product. It works fine, though, so I’m satisfied overall.

Great oil for high-performance engines
I've been using Royal Purple's 20W-50 for my muscle car, and I can really feel the difference. The engine runs smoother, and the synerlec technology seems to help with performance. Plus, it’s perfect for those hot summer days!

Solid oil but pricey
This synthetic oil does a great job protecting my engine, and I noticed it runs cooler. However, I think it’s a bit overpriced compared to other brands. Still, it's worth it if you want that extra performance.
