    Royal Purple HMX High Mileage Synthetic Motor Oil
    Royal Purple's new HMX High Mileage Synthetic Motor Oil has been formulated with robust zinc/phosphorus anti-wear compounds combined with Synerlec propriety additive technology. This premium synthetic oil is chemically enhanced to revitalize hardened seals, reducing oil consumption common in high mileage engines. In addition, HMX is fortified with stout detergents to remove engine buildup and deposits, maintain cleanliness and promote engine longevity.

    The advanced Synerlec technology in HMX provides exceptional film strength, reducing friction and metal to metal contact for peak engine performance. It also provides outstanding oxidation resistance to safely extend oil drain intervals, and an ionic attraction to metal surfaces, providing protection and minimizing engine wear during startup.


    • Recommended for gasoline engines with 75,000 miles or more.
    • Safely extends oil drain intervals up to 15,000 miles or 12 months on unmodified, mechanically sound engines with proper filtration.
    • Suitable for use in engines specifying API service SJ, SL, SM and SN.
    • Synerlec Technology for reduced friction and excellent durability.

    11748 - Royal Purple HMX High Mileage Synthetic Motor Oil is rated 5.0 out of 5 by 8.

    Rated 5 out of 5 by from Horsepower improvement Outstanding Oil. I can definitely feel a differance pushing the pedal. There's a big change switching from conventional motor oil to this full synthetic oil as there's less drag inside the engine. 1998 Honda Cr-v LX @ 179,000 Miles.

    Rated 5 out of 5 by from exceeded my expectations I was skeptical about all the claims of smoother engine and better acceleration from an oil but I was wrong. I switched my 2000 4runner 3.4 v6 with 192,000 miles over to royal purple hmx about 10 months ago and I was completely amazed at the difference. Smoother runner, quicker acceleration and extended drain intervals to boot. It feels lIke it picked up about 10 to 15 hp in performance due to the quicker acceleration. I can't imagine ever running any things else in it from now on.
