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

  • 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.

    I have a SRT GRAND CHEROKEE. With the 475hp hemi. It's a 2015. I purchased it preowned last August. My first oil change I used Castrol edge full synthetic. Seemed to run fine. My second oil change since owning it I ran royal purple. I use a factory mopar filter. I noticed it runs better with royal purple. Smoother idle. Definitely more responsive as well.

    How about testing high rpm armature bearing grease like used on small bearings in vacuum cleaners. Lots of tools use small high rpm bearings to incase that is easier for you to make video of. I repack small high rpm armature bearings frequently on vacuum cleaners and only ever tried 1 product. 2nd suggestion for video would be which food grade grease is better, I also clean and repair KitchenAid mixers a and apply food grade grease to all internal gears. Or how about best tool to remove stripped screw heads or best tool to remove broken heads off of small fasteners commonly found in vacuums and small appliances. Impact wrench seems to also do more harm then hand unloosen. Great videos!! Keep up the great work.

    Back in the 80s the seismic boat I worked on switched from Mobil rarus 827 to some type of royal purple in the air compressor force feed lubricators. Almost immediately we started having problems with compressor exhaust valves. We switched back. After that I would never put a royal purple product in anything I own. I use Motul vw specific in my volkswagen turbo diesel, and I would like to see how it compares. I've had very good results.

    Why do your tubes look slightly slanted more than the others? Isn't just angle, they don't line up.Also, I'm an AMSOIL enthusiast. I use it for all my cars. It's great if it did win. But the tubes for the slow drip didn't look exact. I just want to make sure that all the oils have a fair shot.

    Royal purple is not the same after the Calumet buy out. They ship their oil in cheap metal barrels instead of plastic barrels, and the guys that formulated the original synerlec additive package are not involved in their products anymore. Calumet has cut costs. Those engineers landed at another small company which i will not disclose. But you could find out where if you really wanted to.

    I've always used Castrol 10w-40 4T in my 2005 zx6r. It has around 24k miles on it and I recently switched to Royal Purple Max-Cycle 10w40 and noticed the motor a a little quieter and seems to run a little bit smoother with just a Lil more hp. And yes i have did the jumper mod for all my Kawi peeps.

    You're comparing the bottom/worst grade of Royal Purple to a top end Amsoil. The API licensed RP has to reduce the amount of additives like zinc, phos, moly, and others to comply to API standards.Try comparing Royal Purple's HPS, their middle grade, or their XPS top grade, to Amsoil. Another option would be if Amsoil had an API licensed product to compare to RP API.

    https://youtu.be/oA_VJVHca9YCeck this result please. I have been using 10w60 from this producer as long as I lived in Dubai in a 320v6 Mercedes. And now I'm using it in Romania in weather from -20° to 36° Celsius. And it is amazing.

    Royal purpose has performance additives for more horse power. You didn’t test for that.
