## 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: Happy, Happy - I purchased used 2018 Ford Escape 2.5L(Not turbo), Noticed horrible transmission rough shift to up 40mile. Improved shifting by changing transmission oil 3 times , but still rough shifting was there. I decided to replace Mortorcraft oil(was new oil) with Royal purple oil 5W-20 also added Hot shots Secret oil additive, Improved power and smoothness by instantly after replaced, also, Transmission rough shifting problems are 100% fixed. I am first time user of Royal purple oil and very happy changing to Royal purple. Drove few days later on freeway, seems to be getting much better gas milage.
Review: Buy the BEST! Royal Purple does what it says! IT WORKS! - Well, I changed the oil in my 2012 Ford Fiesta SES 5 speed manual today at 14188 original miles. My engine ought to be broken in by now. My three year factory warranty expired. Time to protect my investment for the long haul. This is my third oil change since I bought my car brand new. My previous two servicing's were done by my local Ford dealership. At the dealership prices. I suppose that the service techs used "Ford" products on my ride since they're a dealership......... Well back to the "Royal Purple" upgrade. After tricking out my Fiesta with the best that money could buy in the past, and after viewing all the available information that I could find, reading the car owner reviews, and seeing oil filters sawed in half, I decided that I would give "Royal Purple" a try. The 1.6L Ford Fiesta engine specs call for 4.2 quarts of 5w20 oil. After installing the new upgraded "Royal Purple" oil filter, I added the four quarts of Royal Purple 5w20 oil, and topped it off with .2 quarts of "Lucas Pure Synthetic" oil treatment. I've been using "Lucas" brand oil treatment in all my vehicles for years so I already knew how good it is. Todays smaller, newer engines require a lighter formula than the original "Lucas" so I bought the "Lucas Pure synthetic" formulated for new engines. I'm Very, VERY pleased with the results in my Ford Fiesta SES! My car runs so smooth and quiet that I have to listen to see if the engine is still running while driving down the road in gear! Now I'm not one to brag, but it DOES seem like there's MORE POWER. Whatever it is, I definitely noticed a faster acceleration without even trying to press the pedal harder to do it! This from a guy that has used over the last 40 years all the oils, gimmicks, gadgets, and snake oils on the market and some that are not even on the market anymore! This is an upgrade that went perfectly smooth, with no pain, and no modifications! Anybody that says Royal Purple products are bunk is sadly misinformed, or just plain stupid. I'll NEVER use any other oil in my hot hatch!

## 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
