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! Review: Get the best and safe - Best oil there is. If you buy it by the case on desertcart, 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. ## Features - Better wear protection - Increased fuel efficiency - Better protection of the expensive catalytic emission system - Improved compatibility with fuels containing ethanol - Superior corrosion protection - Fit Type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005SEK9IQ | | Automotive Fit Type | Vehicle Specific Fit | | Brand | Royal Purple | | Brand Name | Royal Purple | | Compatible with Vehicle Type | Car | | Container Type | Bottle | | Customer Reviews | 4.9 out of 5 stars 2,628 Reviews | | Global Trade Identification Number | 00641330510205 | | Item Type Name | Royal Purple 51020 API-Licensed SAE 0W-20 High Performance Synthetic Motor Oil - 5 qt. | | Item Weight | 3.63 kg | | Liquid Volume | 4.73 Litres | | Manufacturer | Royal Purple | | Manufacturer Part Number | 641330510205 | | Model | ROY51020 | | Package Information | Bottle | | SAE J300 Viscosity Grade | 0W-20 | | Size | 5 Quart (160 Ounces) | | UPC | 641330510205 | | Unit Count | 4731.76 Milliliters | | Vehicle Service Type | Car | | Viscosity Level | Low | | What Is In the Box | oil | ## Product Details - **Viscosity:** 0W 20 - **Brand:** Royal Purple - **Liquid Volume:** 4.73 Litres - **Package Information:** Bottle - **Vehicle Service Type:** Car ## Images ![51020 API-Licensed SAE 0W-20 High Performance Synthetic Motor Oil - 5 qt. - Image 1](https://m.media-amazon.com/images/I/811wOSCf3cL.jpg) ![51020 API-Licensed SAE 0W-20 High Performance Synthetic Motor Oil - 5 qt. - Image 2](https://m.media-amazon.com/images/I/71WE5re-MuL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: I have seen Royal Purple oil being used in race engines for years....what makes Royal Purple Full Synthetic better than say.. Mobil1 Full Synthetic?** A: Royal One is considered one of the better synthetic oils. Notice it does not say 100% synthetic. Only if they say 100% are they completely free of any petroleum based oil. Also note sticker says approved by Petroleum standards. Mobil 1 says this too. A 100% synthetic oil requires no additives. In Europe, fully synthetic = 100% synthetic. In the United States it doesn't. **Q: Is this oil ok to use in my supercharged fr-s using e85 fuel? i change my oil every 5k miles** A: Looks like you keep up with maintenance, so yes, I think it would suit your needs. The first oil change with Royal Purple is a time in which the oil acclimates to its engine environment. You can still get 5000 miles out of it, but with the second oil change you will see a subtle change with oil life extending beyond the 5000 to 6000 or more. In my case, I am getting 10000 miles between oil changes, and the oil still has no burned smell to it. I do recommend using a good oil filter as well, like Wix, or something that can take the temperature ranges. If your engine is using oil, then I'd be cautious in making the switch, otherwise I have no regrets. With the last rebuild on my 1988 Jeep Wrangler I started it off with Royal Purple and haven't looked back. Engine runs smoother and I get the extended oil mileage. **Q: Is this listing for 1 quart or 6 quarts?** A: this is for 1 quart only **Q: Does this work for the 2013 toyota prius v? i am looking for this with 75,000+ miles with royal purple hmx high mileage synthetic 0w-20 ilsac gf-5 mul** A: I use it in my 2017 prius 2. It works great. Comes out looking damn near new after 10k miles. When i need to switch to high mileage oil, i will use HMX. ## Customer Reviews ### ⭐⭐⭐⭐⭐ RP is the best oil *by B***. on 22 October 2024* The best oil on the market.
