Been wanting to try Royal Purple for a while and finally gave it a shot in my daily driver. Engine feels a bit smoother, and startup noise is a little quieter than usual. The deep purple color is a nice touch and makes it easy to see the oil level when checking or pouring. Shipping was fast, but the bottle had a small scuff on the cap — didn’t affect the seal though. I keep this quart mounted in my truck using the TripleD Tools Oil Dock, and it’s held in nice and snug. No sliding around and always ready when I need it.

The best oil you could get for your car and it last up to 12k miles so I change mine every 10k miles. Me and my dad use this brand for every car we have and helps the car last for miles. We got cars that’s way over 200k miles and still running good.

I decided to use this motor oil as I have read the rave reviews on it but due to the cost of these, I stayed with my usual Castrol Oil. Since it was on sale, I decided to buy 1 and give it a try and I understand why this oil has so many positive reviews. I found that my engine performed better and ran smoother. Also, I got better MPG's., so it is well worth the extra $$. While it was still on sale, I purchased 2 more of these.
