If you run the RP HPS non-API in your daily driver that you are quite aware of it's performance, after switching, you will notice an increase in performance in the seat of your pants compared to the regular on the shelf oils like Mobil 1 or Valvoline synthetics. If Royal Purple could put their magic "Synerlec" additive in their API rated oils, it would be in there. Royal Purple would be richer and famouser! Synerlec is what separates them from other oils. If people are buying the regular RP they won't notice that performance change. They are both good oils imo, but if the main purpose is cleaning go with the Valvoline R&P.

Yeah, no. I switched to HPS in a vehicle that saw nothing but maxlife synthetic from new, to 85k. I experienced none of what you say. I did see an improvement in fuel mileage but there were so many factors at play I can’t even verify that. It was much darker than normal @5 k so maybe it cleaned better, but who knows. I’ve also ran the worlds greatest oil (hpl) and my Nissan didn’t turn into a Bentley at midnight either. The benefits of boutique oil is not having your 1.5 turn into a 5.7, it’s the abuse it can withstand from your engine.
I don't sell their stuff; I just used it off and on. There really is something different about the Royal Purple oils that have that Synerlec additive in it, it is not an imaginary thing. It is a good thing. For a time, years ago when I owned and operated my own class 8 trucks I ran their Heavy-Duty Diesel oil (with their Synerlec) in my truck. After a few hundred miles the engine was quieter and smoother at idle and I got a noticeable increase in my fuel milage, which I kept track of very closely. There is something to it that is good for engines compared to other less expensive brands. I am sorry Royal Purple left such a sour taste in your mouth D1dad, I have had some good experience with it in my past. It does cost too much though, especially the ones with the Synerlec in them. There is another brand of oil I used in the past that could give similar results somehow. The Brand was Lubrication Engineers; this is their website: https://lelubricants.com Their lubricants are way too high priced too, but they do have that " something special" quality to them when in use. Anyhow D1dad, have a great day. Thanks for responding to my oil story. Joel
Really now. You can feel the difference in engine performance? That’s quite a feat.
I’m not disagreeing that Hps isn’t worlds better than the Walmart RP, cause it is. It’s what RP used to be before they cheaped out. I’m going to run my current fill of HPs in my 21 the entire OLM and not bat an eye. Just to double my chances of my engine grenading, I also have a purolator boss on it. My nephews bridge building company were having to rebuild their bore machines at least once a year, they got with RP engineering and went all last season without a spun bearing. My nephew isn’t the most technical kid in the world (he’s 21), but he said afterwards they converted every piece of equipment over and haven’t looked back. It’s not well liked on here so whatever. I’ll still use it.
Yes, if it is their engine oil that includes the Synerlec magic potion, which is not their API rated oils. The recent one I used was their 5w-30 HPS. I don't know if it somehow makes thing cleaner and in turn work better, is it just slicker somehow, or does it cause a better ring seal causing a slight increase in compression? Either case I have noticed good differences when using it, it is not "in my head" and the stuff is too expensive to run all the time.
Wow. You must have quite the butt dyno.
I do, as a matter of fact. I spent my entire life sitting on it. It is well calibrated and notices any and all changes that may occur! LOL!
I've always used RP in my Mazda Rx-7 race car without any issues. I'd say give it a shot run it for 5-6k miles then send it for a uoa.
I buy HPS in 5 gallon pales, the price isn't bad per Qt like that.
There is nothing special about their shelf oil at Walmart and it is way overpriced for what it is.
Absolutely! I agree.
The OP has pointed out that the RP is being sourced at $22 for the jug, net. He already has the correct OCI. This puts the RP down in the ranks of the cheaper oils (saw QSFS on Amazon for $20 plus a few Pennie’s recently.). At the price, and without the specific need to clean out an engine, I’m going with RP). Full disclosure: I have never used RP!
I just drained Hps out of one of my cars @6500 miles. Man was it black! This was on a car that’s saw regular oil changes with idemitsu for the 1st 35k, then hpl, then schaeffers and this last run being about 70/30 highway. No drop on the dipstick and no obvious fuel smell. Hps 5-20 will go back in about 1/2 hour from now. Sadly no butt dyno with any of these oils.

Have you cut open the filter for any of these runs? Oil colour isn't overly valuable, as different components respond to oxidation differently and it's not uncommon for some of them to darken considerably, which makes oils with these compounds in them go "black" very quickly. People have posted about Pennzoil Ultra Platinum staying clear on the dipstick the entire OCI for example.
Now that is sad to hear, you have been running the good stuff for oils. It should be fairly clean inside since you have been using those somewhat higher quality oils. Run that HPS for 4 or5 hundred miles and see if you notice your butt dyno talking to you, and I am not talking about after a trip to Taco Bell! Let me know what happens. Also, what was your impression of the Idemitsu oil when you ran it, anything good or bad to say about it? I have run the Schaeffer Oil off and on through the years. I still like it, but I have to take a 60-mile round trip to pick it up. The price for Schaeffer Oil on Amazon is crazy. My Schaeffer distributor here gives me a fair price, but I have to feel like taking a drive to go get it.
Isn't it purple (dark) to begin with?
If it was Royal Purple HPS, yes, it was purple when new.
