HMX w/Synerlec | High Mileage SAE 5W-20 Premium Synthetic Motor Oil |5 Quart | SKU: 17518

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!

I have been using fir long time. Little pricey but quality is awesome and when I change the old oil it is still good on 5000 miles.

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.

This is my favorite oil, I love how it’s purple to at that dope color quality oil. I’ve noticed improvements since running this oil in my 5.7 hemi.

Have never seen the high mileage, but it makes the car feel even better now. The quality of the oil is amazing, amazing price aswell. Highly recommend using high mileage royal purple in your oldies, keeps em running strong 💪

It’s the good stuff. My friend uses it in his Hellcat. I put it in my Laramie

Great
