Royal Purple 51520 API-Licensed SAE 5W-20 High Performance Synthetic Motor Oil - 5 Quart, (Model: ROY51520)

Best oil, high performance, great fit, seals, lasts forever.

It quiets minor engine noise (does NOT have a hemi tick issue) and also flows faster during cold starts. My Hemi never sounded better. In fact it's so quiet I'm amazed! I used to use Valvoline Advanced Formula full synth (excellent product too) but I decided to try Royal Purple based on rave reviews. I couldn't be more impressed and happy with this product.

Great product I change my oil every 3,000 miles and have used this since the vehicle had 47,000 miles just recently did some upgrades to the engine and at 136,000 miles the inside of the engine is super clean.

I have been using this oil in my 2017 Ford F150 since I bought it in 2018, I used it in other vehicles before. Yes it costs a little more than other oils but to me it seems to be a better product. My engines haven’t given me any issues with this oil, and even changing my oil at 5,000 mile intervals the used oil is still sometimes purple instead of black. Ordered it from Amazon because it was cheaper than my local stores.

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.

👍⭐️⭐️⭐️

By far, the best oil that I've ever used. Compatible with other oils and performs great in all temperatures. Worth the extra money for various reasons including longer change intervals (I usually go 10k+), great protection, increased performance and improved MPG. I use it in my 2016 Ram 1500 5.7L (starting at 35K miles) and 2009 Honda Civic LX 1.8L with improved performance in both. It reduced oil consumption in the Honda (154K miles), which I use as my work commuter and drive over 100 miles daily, sometimes much more, so I'm very cognitive of gas mileage and long term performance. I expect that to continue to improve in subsequent changes, as I've only been running RP for 8K miles. I'll never run conventional or a lower quality synthetic again. It out performs Mobile 1 and more versatile than Amsoil.

Oil you can trust.

This is the best synthetic I've used to date. Slight power gain, engine idles smoothly.

De lo mejor. Un poco raro que sea morado pues se confunde con usado pero eso es solo estetico

I have used Royal purple for a number of years. It has a significant advantage over any conventional or semi-synthetic oil. Cold weather starts are easier in winter and I have had no problems with hot weather operation.

I've relied on Royal purple for years in all my vehicles, well worth the price if you want to keep you vehicle for a long time.

Good oul
