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

  • Published on: 04 March 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.

    Hey, I love the video. Would you be interested in testing Subaru OEM synthetic oil (5W-30 for turbo cars)? I would ship you a quart or two for the testing; I don't have the equipment to do any of the testing you do, but again, I can send some oil to you for testing!

    How do they flow out of the bottle at room temp? Is there a viscosity difference for advertised oil weight between brands ? Interesting. Thnx

    Royal Purple has a full synthetic for diesels, you should compare it to others.

    These oils aren't even apples to apples... an API oil vs a non-certified API oil (and that's just one flaw in your "test").

    Not comparing apples to apples here, testing any API or Dexos certified oil against a non certified oil gives the certified oil a handy cap. API and Decos have a very narrow range of specs that doesn’t allow for much variation fro one brand to another. The non certified oil can have a lot more additive enhancements.

    Whelp... I've been using mobile 1 for years. I think it's gonna change after watching this video. Amsoil it is! Thanks for the video comparison!

    We were given free 2-stroke amsoil back in the late 90’s on a JetSki tour. I noticed a huge difference in multiple engines life and overall wear. Not to mention WAY less smoke. Granted, 2-stroke Vs 4-stroke is apples and oranges.

    Yes, I would like to see Amsoil vs. Mobil One, but the showdown you described would be fantastic. Enjoyed your video.

    Great posting!! I spoke to my BG representative and he claimed the founders of AMSoil split and Royal Purple split. The agreement was the formula was exactly the same for AMSoil and Royal Purple. However, the Royal Purple came up with an additive that was very similar to BG Motor Oil Additive, but called in Synerlec and dyed it purple. That was many, many years ago. I have not found any online proof to support that claim. It does not mean its not true. In addition, neither BG Products nor AMSoil are API certified, but both are great oils! I've been using Royal Purple and BG oil for over 15 years.

    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!

    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.
