Is Royal Purple better than Amsoil? Let's find out!

  • Published on:  Monday, March 4, 2019
  • Is Royal Purple's full synthetic 5W-30 motor better than Amsoil's 100% synthetic 5W-30 motor oil? In this video both products go head to head in several tests. Both Amsoil and Royal Purple are very high quality synthetic motor oils. I bought both of these products using my own money. I am not sponsored by Amsoil or Royal Purple, and I do not sell Amsoil or Royal Purple products. The testing methods outlined in this video are my own and not performed using expensive oil lab testing equipment or following the ASTM, SAE or API testing standards. The three tests outlined in the video include tests for viscosity at varying temperatures, film strength, and evaporative testing. In my opinion, the testing approaches used in this video provide consumers with valuable information on choosing the right motor oil for their specific application. Hope you enjoy the rest of the video and thank you very much for supporting the channel by watching the commercials and through Patreon support.

    How about Pensoil Synthetic with Amsoil comparison? Pensoil claims that their oil comes from natural oil instead of crude oil. It may slow better?

    I honestly thought there was no doubt that Amsoil was the best oil money could buy. I would always take that over RP any day. It is expensive, but it WORKS!




    Please review the differential oils, amsoil 75w140 and redline shockproof 75w250 for differences. Keep up the great work.

    Are you able to do a test with Royal Purple HPS instead of the API in this video? HPS, HMX and XPR have the Synerlec additive and better anti-wear where API doesn't for warranty regulations. Thanks

    As a motorcycle rider. I would like to see if Honda wet clutch motor oil is better that day a name brand wet clutch synthetic motorcycle deemed "Safe" for wet clutch bikes. I would like to see which better lubricates the engines and allows less clutch slip at operating temp. A bit tricky of a test though.
