## Description

Royal Purple API-Licensed Heavy Duty SAE 5W-20 High Performance SN Synthetic Motor Oil is fully synthetic - not made from crude oil like traditional motor oils. It's used to lubricate, clean, and cool engines with the utmost efficiency. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. This oil has a weight of SAE 5W-20, meaning it has an SAE viscosity rating of 5 in cold temperatures and a rating of 20 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle. Synthetic oil can be used in vehicle engines instead of motor oils refined from crude oil, and often provides superior mechanical performance over traditional motor oil, including increased gas mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil. Royal Purple Motor Oil Combines premium base oils with proprietary additive technologies to create high performance motor oils that optimize engine performance and provide superior protection. No special procedures are necessary when upgrading to Royal Purple. Royal Purple motor oil is fully compatible with mineral or other synthetic oils. Royal Purple recommends waiting until the manufacturer's first scheduled oil change in new gasoline engines before upgrading to Royal Purple. Royal Purple's API licensed motor oil delivers superior protection and improves performance in gasoline and diesel engines. Royal Purple's API SN licensed motor oil meets ILSAC GF-5 and Dexos1 1 performance requirements.

Review: Best oil period - Best oil, high performance, great fit, seals, lasts forever.
Review: Nice upgrade oil with a sharp look - 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.

## Questions & Answers

**Q: Do I need to use a Royal Purple filter to get the best performance of this oil or will any filter do?**
A: I use fram filters. In the vehicles that I need to be very reliable I use the expensive Walmart Fram Filters. In my around town vehicles I use the cheap fram filters. I have had no problem with any of them. You will enjoy the Royal Purple. Just make sure it shows up on the oil dip stick. My Ford F150 used 9 quarts the 1st time. Not the typical 6 quarts. Now it uses a little over 7 quarts.

**Q: What is the shelf life of this oil**
A: This oil is synthetic. It will not break down or become contaminated like traditional oils may. That said, only buy what you think you'll use in the next 60 months. If you buy this 5 gallon model, consider how many other vehicles can benefit from it. I have two cars, both of them use 5-20. So for me, this is a no-brainer purchase.

**Q: some have dexos some dont, why? mine arrived with no dexos logo**
A: The dexos specification applies to most, but not all, GM vehicles model year 2011 or later.   (I) have a nissan, I do NOT use Dexos.  I've no idea if Dexos is superior in MY vehicle but since it is NOT specified, I don't use it.

**Q: when will oil filter for Genesis 5.0 be available?**
A: what is Genesis 5.0
