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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly Recommend! *by J***L on 13 August 2022* ### ⭐⭐⭐⭐⭐ Five Stars *by A***R on 3 August 2017* ### ⭐⭐⭐⭐⭐ Best oil period *by S***Y on 21 March 2026* ## Frequently Bought Together - Royal Purple 51520 API-Licensed SAE 5W-20 High Performance Synthetic Motor Oil - 5 Quart, (Model: ROY51520) - Motorcraft FL-500S Oil Filter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/291004703-royal-purple-51520-api-licensed-sae-5w-20-high-performance](https://www.desertcart.co.uk/products/291004703-royal-purple-51520-api-licensed-sae-5w-20-high-performance) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-14*
