51020 API-Licensed SAE 0W-20 High Performance Synthetic Motor Oil - 5 qt.

The best oil on the market. Recommend anybody to make the switch, particularly if your car is still under 100,000 km though I did switch my 2008 Kia Sportage at 150,000 km with no problem. It really cleaned the engine too and subsequent oil changes had cleaner oil coming out!

Best oil there is. If you buy it by the case on Amazon, and take it to a quick lube, or do it yourself, you know that it done right. I don't trust dealerships anymore they will rune your car just to sell you more part.

Huele muy bien

Best motor oil on the market , I change it every 3,500 miles and my engine stayed spotless and leak free for 130,000 miles now and never a single engine issue

I have used this brand for years. used it in several vehicles, I even use it in my lawn mower. never had any problems out of any of them. seen noticeable improvement in all of them. I mostly started using this to try a squeeze a few more MPG out of my HEMI Ram and the longer oil life cycle. the longer life cycle alone is worth changing over. I normally go about 8,000 mils on one oil change, but you can go all the way up to 12,000 mils. with my car still being under warranty, the dealer told me to stay at 8,000 so I wouldn't have problems if something were to happen with the car. that would still be longer then 2 1/2 normal oil changes. as far as MPG when switching from a reg oil over to Royal Purple I saw a good half a mile better then I was getting before. which for me just switching my oil over, half a MPG is a huge improvement. for me i'm also supporting local eco, Royal Purple is made just a few miles down the road from me. plus Royal Purple being a full synthetic oil (meaning that its mostly man made) means that your also helping the environment and cutting down on the use of crude oil. i'm no tree hugger, just don't like giving my hard earned money to other country's.
