Good oil
I use this on my wife’s Jeep Wrangler with over 115,000 miles. Recently replaced valve cover gaskets and had little to no varnish on heads! Have always used Royal Purple since owning the Jeep. Using a good oil is just as important as using a good filter!

Best oil look no further
This oil is great because it last alot longer than most traditional oils its great for me considering i always exceed the miles that I should have done my oil change at and even then the oil still looks good I would recommend this product to anyone who is like me.

Can feel the much smoother engine performance…truly remarkable improvement!
I changed from Pennzoil and am totally amazed at how much smoother my 5.7 hemi runs..night and day difference. I’m a believer now! I’ll stick with this oil permanently!

High quality oil
I've used amsoil most of my life, but switched to royal purple because I believe it's just as good if not better oil at a lower cost. Plus all of the additives for higher mileage vehicles like my truck. It just works.
