Best darn oil on the market. Worth the extra money.
-
This is a great oil for older designed engines according to mfr. Website this oil contains zinc
-
This oil works very well especially in cleaning the internal engine!
-
Great synthetic oil, quiets noisy valves on my 1990 Bronco 2! One of the few brands I buy.
-
Been using royal purple for decades. Excellent oil.
-
Noticeable reduction in engine noise, but also accelerates more smoothly. I’ve also used the non-high mileage RP before with similar results. Oil analysis (sent to a lab) from standard RP oil shows it’s truly a superior quality oil that you cab totally run longer (just change the filter). A item!
-
I’ve been using Royal Purple for years and it’s great. Perfect for older cars. Would recommend to anyone.
-
I have been using this brand for over 20 years. I put it in everything I operate.
-
I don’t know anything about oil, but I watched the video and was impressed. I have used this oil for 3 years now. My son-in-law is a mechanic, and he recommended it.

My mechanic asked me why I use, “Royal Purple” synthetic oil. My reply, “it’s the best for Italian machinery’s and used for racing and Ferraris.” My mechanic’s reply, “you don’t have a high performance car, it’s only a ’97 CL 2.2 Acura. I said, “that’s right and why it’s just that much better to use in my car.” Check it out on line.
