For me the best oil for my vehicle

Rated 5 out of 5 by MoparErik Best oil I've ever used
Royal Purple is the best. I had to switch my oil changes from every three months to every six because every time I changed at that interval, the oil came out clean. It still comes out fairly clean at six so I'm thinking of moving out to every nine months. I changed the oil pan in my 15 year old Dodge truck a couple of weeks ago during my last oil change and the pan was pristine! I've used RP exclusively in my vehicles for close to 10 years and I can assure you that it makes a world of difference. I will not use anything else.

Rated 5 out of 5 by Al31 Royal Purple Useage and reliability
I have used Royal Purple for the past 15 years. All my cars run perfectly, quietly, and with more power. I use it in my current three cars and have used in my corvette and other cars I have owned. I also get longer use and have used in only in every new car I have bought over the years. Every engine runs with no problems. Best oil on the market. Also checking my exhaust shows hardly any black soot after 6 years. I have less pollution from all the cars in the family. I have used many oils over the years as I am 74 years old.
