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.

    Interesting video. I found out the AMSOIL at 9 minutes is the same color and viscosity as the discharge from my junk in the morning. Thanks for posting; im going back to the doctor now with this revelation.

    Awesome video. Very objectively done. Even rotating the pots on the griddle to ensure even heating. Hats off to an informative vid. Would you do a video on motorcycle oil? Curious about Quicksilver 20w-50 Wal-Mart brand full synthetic vs. Harely Davidson's SYN 3 20w-50 full synthetic brand oil. The price difference is considerable. Let me know! I'll definitely throw some patreon support to cover the expense of two quarts plus! I think you'd also pique the curiosity of

    I have used Amsoil products in everything I own for about 20 years including engine oil, gear oil Auto. transmission fluid, grease, 2 cycle oil, oil and air filters and I would not go back to other products for nothing especially having to crawl under a vehicle every 3-5 thousand miles for nothing, everything I have put it in has always been impressive, hands down,
    keep up the good work.

    According to an Amsoil rep who is also a popular tech/mechanic garage owner in the Orlando area, if you use Amsoil exclusively in your brand new vehicle, Amsoil will add their own additional warranty to that engine.
