    5.0 out of 5 stars Great motor oil!!
    Reviewed in the United States on July 11, 2024
    I have been using this brand of motor oil for the past 2 years, and believe me: it is really, really great oil! My car is very satisfied with the performance that the oil provides. I will never use another brand as this oil provides all that you need in a motor oil. I even use the their lubricating grease for my ball joints and essential grease fittings on my car. Great stuff and worth every penny. Also, does not break down easily in viscosity, and I also notice that the oil stays clean until my next oil change!!!!

    One of the few oil products I’ve used where the is no noticeable difference in engine performance right after an oil change=means the viscosity and conditioners continue to work straight through to the end of its change cycle. Also one of the only higher quality oils that is readily available, easy to find, and is negligibly more expensive than the garbage many of the “Quick Shops” use.

    5.0 out of 5 stars What Penzoil use to be
    Reviewed in the United States on July 28, 2024
    Penzoil full synthetic use to be an excellent product for over a decade but as of 8 years now it gone down drastically in quality. I have a 2012 Honda cr-v with close to 250000 miles on it. About 8 years now, I noticed that my car’s fuel efficiency was getting worse and I was burning oil to where I had to add a quart before the next oil change. I researched Google and there where many other car owners having the same issue. One of them said that he changed to Royal Purple and his car was back to being fuel efficient and not burning oil. So I paid more for it and checked it out. He was right! My Honda is back to being as fuel efficient as when I bought it brand new and I don’t have to add any oil between my 12000 mile oil change. Yes! 12000 miles. I recommend you try it out. I hope that Penzoil get the message and improve their product.

    5.0 out of 5 stars Great Oil
    Reviewed in the United States on August 21, 2024
    After switching to royal purple, I didn't notice any difference at all with the car after the first oil change. BUT When I did the second oil change, lol, I had a new car!! Everything smoothed out and got soo quiet. Do 4k to 5k mile for the first oil change, to clean the engine real good. And with the second oil change do 4k - 5k. You gonna be shocked the night and day difference after using royal purple oil, guaranteed
