## Overview

Royal Purple 5W-40 Synthetic Oil is a premium fully synthetic motor oil designed to optimize engine performance and protection. It features a unique ester-based formula that clings to metal surfaces, reducing dry starts and friction while improving fuel efficiency and horsepower. Rated SAE 5W-40, it performs reliably in extreme temperatures and meets API SN, ILSAC GF-5, and Dexos1 standards. Ideal for gasoline engines requiring high-performance lubrication, Royal Purple offers superior engine cleanliness and durability for the discerning driver.

## Description

Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. 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. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance. This oil has a weight of SAE 5W-40, meaning it has an SAE viscosity rating of 5 in cold temperatures and a rating of 40 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. This oil is fully synthetic, meaning crude oil is not used in making it. Synthetic oil 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: Royal Purple Synthetic motor oil - This is an area that I am very familiar with as I previously distributed synthetic oil. During this period I befriended one of the leading scientists who created and formulated synthetic oils. We spent a lot of time together and I often accompanied him to several industry seminars. I received quite an education about oil. Briefly synthetic oil does everything your regular motor does, only it does it better. Plus Royal Purple uses a different base stock (ester) then regular and most other synthetic oils--it clings naturally to metal. thus reducing dry starts (a leading cause of engine wear), reduces friction; has a higher film strength; reaches operating temperature quicker; runs cooler and has a greater resistance to high temperature breakdown;has a high solvency action that will clean the inside of your engine; it has a lower freezing point point, ie. it will not thicken up in the coldest of climates, and finally it will increase your HP and mpg. In my opinion Royal Purple is the best synthetic oil on the market today. Is there a downside? Yes it is expensive and hard on valve seals. If you have an older car with a lot of miles on it (about 60,000 or more) the seals and rings may be filled up with engine deposits and the oil may flush them out,leaving you with an oil burner. We had this problem on my friends Saturn. The oil made a big difference in performance and mpg, but it began to burn oil. So on the next change we dumped it and replaced it with Mobil ! and Lucas Synthetic Oil Stabilizer and the oil consumption ceased. It was a better performance then regular oil but not as good as the Royal Purple. Also suggest you use Royal Purple transmission oil, it does make a difference. Don F Los Angeles

My choice for quality motor oil.

### ⭐⭐⭐⭐⭐ Great Stuff
*by L***E on August 9, 2015*

I am now on the second interval of using 5W-40 oil in my wife's 2003 VW Passat 1.8T. The engine has almost 150,000 miles on it, and I have been running quality synthetics through it since I have owned the car for the past 90,000 miles. The engine feels incredibly smooth running this oil even at high RPMs. When I drained the oil after the first interval using it, the oil came out looking really good and thick. I am planning on pushing the interval to 10,000 miles this time, but I don't know if I will be able to hold off for that long or not. Regardless, I still feel like I am getting good value for my dollar. If there are people reading this running the 1.8T, make sure you are getting the bigger oil filter for the extra capacity on the longer intervals. The only issue that I have been seeing is that my car seems to be burning some oil, but the mileage is getting up there so maybe that has something to do with it. I am now fully hooked on this oil.
