Royal Purple HPS 5W-20 High Performance Street Synthetic Motor Oil with Synerlec - is not made from crude oil like traditional motor oils. It's used to lubricate, clean, and cool engines with the utmost efficiency. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. 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. This oil is a full synthetic oil, meaning crude oil is not used in making it. 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 HPS Series motor oil is specifically formulated to maximize performance and meet the demands of high performance and modified engines. It is fortified with a high level of zinc/phosphorus anti-wear additive and Royal Purple's proprietary Synerlec additive technology. This unique blend enables HPS to outperform leading synthetics and conventional lubricants. The available viscosities include 5W-20, 5W-30, 10W-30, 10W-40 and 20W-50. HPS is recommended for vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection. Royal Purple's HPS Series of motor oil responds to increased pressure with increased viscosity. It's advanced additive technologies, such as Synerlec improves the condition of metal-to-metal contact under severe conditions for greater protection.

Royal Purple HPS 5W-20 Synthetic Motor Oil
Royal Purple HPS Series motor oil is specifically formulated to maximize performance and meet the demands of high performance and modified engines. HPS is high performance street motor oil recommended for vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection.
Royal Purple’s HPS is fortified with a high level of zinc/phosphorus anti-wear additive and Royal Purple’s proprietary Synerlec additive technology. This unique blend enables HPS to outperform leading high performance synthetic oils and conventional lubricants for both gasoline and diesel engines.
Royal Purple HPS Series of motor oil responds to increased pressure with increased viscosity. Improved sealing between the piston ring and cylinder wall maximizes horsepower and torque. Its advanced additive technologies improve the condition of metal-to-metal contact under severe load. The advantages are clear. Take a look at the following photos:
Exceptionally high film strength dramatically reduces engine wear and engine heat to extend the life of your engine. Improved sealing between the piston ring and cylinder wall maximizes horsepower and torque and optimizes fuel economy. Exceptional oxidation stability extends oil life and allows for more miles driven between oil changes saving you time and money and reducing the impact on the environment. Advanced synthetic solvency reduces engine deposits and keeps engines clean for increased fuel economy and engine longevity.
HPS protects valve trains using roller or flat tappet lifters that require added protection due to high lift/ high ramp rate camshafts. It also provides maximum protection, extends engine life and ramps up efficiency. For vehicles under warranty, Royal Purple recommends its API-licensed oils available at retailers nationwide.
- Maximum wear protection
- Improved performance
- Better efficiency
- Advanced protection
- Superior corrosion protection

In step Royal Purple. Change the oil and the tick goes away for the first time since I purchased it. Now it comes back when the oil gets close to needing to be changed. I use it at every oil change now and haven’t had any issues.
This isn’t the first time purchasing Royal Purple through amazon, but it is the first time it has leaked. It looks like a manufacture issue, not amazon because the bottles were taped inside the box from the manufacturer. I suspect amazon didn’t do anything, but one call and I was refunded 12% for the few ounces I had lost and had to replace. They offered a 100% refund if I returned it, which seemed like a waste for just a few ounces, and opted for the 12% to save amazon money and me the time. I couldn’t be happier with Amazon and love how they stand behind the items they sell! I couldn’t get that level of service from any of the brick and mortar stores around here on the products they sell.
I started using RP 20/50 with the zinc at 120k. Within a few short days, the few drops of oil on the floor disapeared. This little engine is turning 4000 rpm at 80 mph. She burns a quart every 1500 or so but runs so smooth doing it and doesn't leak a drop on my tiled garage floor. I am confident that if I hadn't t started using it, I would've had some kind of engine repair by now. I change the oil and filter ( also RP) way more than I should....and I don't mind. Keep in mind its only a 1.8, I'm not gonna outrace anyone! But on the hiway, I keep up with anyone I want....under 3 digits. 5000 rpm's seems a bit much for extended driving, I'm old(er) not crazy, yet. I use RP in my F-150, my wifes Sonata and my 79 MG Midget.
In my book, this is the best oil you can buy, period and It's probably the cheapest thing you can do to keep you car out of the shop.
I'm a proud supporter of Royal Purple for now. I just switched from the HMX blend to this HPS blend. I will be sending the HMX in for analysis at Blackstone Labs, as I put 10,000 hard miles on the oil (out of the advertised 12,000 interval).
When I receive the results of the HMX, I will post them here. I believe that this HPS should perform better than the HMX however.
For the record, this oil has a 15,000 mile advertised interval.
When I receive specifics, I will report them here.
2-5-16 Update! I have the results for the HMX oil.
This is NOT an analysis on the HPS oil that you are looking at, but it is still Royal purple.
The analysis is up to you, I will not sway your opinions at all. All of the Royal purple blends claim 15,000 miles, but based on the results I received, I would not run the HMX oil longer than 7,500 miles.
I do not know about the HPS oil yet, and I will have an analysis done at 6000 miles when I change the filter. I will post here.
A lengthy email to Royal Purple about my disappointing analysis has revealed some new information.
He (the gentleman I was emailing) has confirmed that yes, my lead levels are higher than normal for the extended interval. But only slightly.
He explained to me the source of the sodium (he said that he suspects I added one replacement quart of the regular RP oil rather than an hmx blend, which may be possible.), and how my 1.5% concentration of fuel is certainly to blame for the low flash point.
He then went on to say that typically, your motor should be run on at least two regular-length intervals on Royal purple, before attempting extended miles.
This is because of two things,
1: to remove all of the old oil effectively.
2: to prevent filter clogs, as RP oils have an agressive cleaning property.
I did not do the two short (5000) mile intervals before going for 10 or 15k.
As suggested by Blackstone labs, I will be sending in a sample at 5000 miles. (3.5k away as of 2-24-16)
I shall be updating soon. Stay tuned!
Meanwhile, I have bumped their rating back to 4 stars for their excellent customer service.
I had a good long email session with him, and he was professional. A pro, if I may. After I was satisfied with his answers about my oil, I asked about my transmission fluid.
Then he went and researched all of the specifics on my transmission. Everything from model number, to the capacities. 3.6 qt in the pan, 7.4 total.

Leaving a 3 star review because even though the top was taped up, a bunch of oil had spilled during transport.
At minimum a couple of litres was spilled, so that is annoying/disappointing.
Royal Purple 5w-30 does its job. Might switch to Rotella T6 however for my n54 e92.
Good stuff !!!!
