Royal purple

How can a full synthetic be run off the mill ?

Back when I ended up choosing them I did at least in part because they were claiming to be synthetic as opposed to syn-sounding with some "syn" in the name but no "thetic" to be found :)

If a run off the mill synthetic will coke my rings and looks like Pepsi at 2k miles, I feel I should have ran to another mill.

Especially as another run of the mill right now is seemingly fixing the mess, at a similar price per quart, and very much run off the mill and off the shelf.

Run of the mill as compared to other full synthetic oils on the same shelf at Walmart.

Do you know what synthetic means? It means synthesized. Lots of those on the shelf.
 
I have had excellent results with Royal Purple SP rated engine oil,if price is a concern watch for sales and rebates, as I would use this oil over some of the popular over emphasized ones mentioned here.

Dunno ?
Synthetic to me means group IV base, and how Mobil shouldn't have lost its court case agains Castrol in 1999. Nothing against other oils, it's just that they should have been called semi-synthetic or whatever, the way they were in Europe.

And RP somehow slid in my list as one of the good guys, starting with the right base, almost like some sort of Maxima or Amsoil or Motul available at the local oil shop. However, it turned out they have Synthetic, and More Synthetic, apparently, and the Synthetic, say, doesn't coke rings, per se, but doesn't care if they do, it looks like ;)

So there. I hereby submit that if a company proudly lists its oils as "Mineral", "Semi-Synthetic" and "100% Synthetic" - they'll have my trust, and that I should have made the extra effort to just buy what I knew was good, and pay a mechanic to do my oil changes when I didn't have space to do it. OR, should have gone Pencastromobhell and do 3000 mile OCIs. Rather than do an effort to find a shop and think I'm doing the right thing by going the extra mile to use something I thought was above average.

why not use Royal Purple 0w-40 ,maybe its better oil.

If it's SP, I'll look for it at Walmartdotcom. Otherwise No thanks.
My next 0w40 motor oil to experiment with at Walmart, will be the Pennzoil Ultra Platinum SP. Won't be until 2026 sometimes. I have 18 bottles (three cases) of Mobil-1 Euro 0w40 still in my garage. Plus several bottles of HPL.

In case you're wondering.... I only buy SP (or equivalent). No SL - No SN - No SN Plus.
Hyundai and Kia to blame. Short OCIs.

Royal Purple (the non-HPS synthetic) is indeed SP, and is widely available in my local Walmart. It's not even that expensive, all things considered. Not sure about other Walmarts. Mine has RP, and the Euro Mobil as well. I was getting that one for my n54-powered Beemer to top off when I was losing oil from my oil cooler hoses.

Now that the leak is fixed I feed it with Liqui Moly, not because I like it (I have mentioned extensively that I'm an oil snob and have absolutely irrational preferences in oils), but because it has the UV dye built in, which, errr, matters with BMWs :)

And FCP Euro takes it back (which I have to see how it works as I'm new to beemers, but it apparently works, plus I'm actually a 25 min drive away from their actual store and don't have to ship it).
 
I’d go with Hps or hmx over the Walmart RP. Hmx is now available in 0w20 and has synerlec (whatever that is)? I ran about 80 miles round trip last night and mpg was up a tad with Hps 5w20. Even with winter blend fuel and my mpg killing cc2s. I can’t say I’m excited about using 5w20 in a car that specs 0, although it’s probably not a big deal as much as I’m a stickler for oem specs. Once it warms consistently I’m sure it won’t matter. I’ll probably use this in my 21 in a month or so and run it all summer.

I buy the HPS 5-30 in 5 gallon pales and it is pretty reasonable per QT like that, I don't buy the stuff off the shelf at Walmart because I think their shelf stuff is way overpriced. Just did a UOA a couple weeks ago on the HPS and Zinc was 1311ppm with Phosphorus at 1240ppm.

Ahh yes the nonexistent court case.

Oh and by the way, nearly all of Europe was calling hydrocracked oils “synthetic” way before it was marketed that way in the US. And Mobil was the one doing it.

So there.

Yes, all dreamed out in this here forum:

Thread 'The Castrol/Mobil "court case" - how it went down'

Found this this morning and thought that it was a good article on WHAT was argued and decided on and by who.

Will post a lot of the article, just in case it goes missing on the Interwebs

Did you even read the thread? There was no court case and no court decision was ever rendered. Ever. It was a marketing ruling by the NAD. It could have been ignored by either party as the NAD had no authority to force anything. Someone could have taken the other to court after that but it did not happen.

And I am exactly correct about how hydrocracked synthetic oils were marketed in nearly all of Europe before they were marketed that way here in the US. The US was actually late to the party.

You’re just one of the many mistaken people who claim it was a court case and also claim “Europe” was different. “Europe” isn’t any different today and it wasn’t back then either. Germany has a marketing rule (not a law btw) but that’s the only country in Europe.

Hey, what do I know. I only lived in Europe till 2004. Ok.

I guess that explains why you didn’t understand the NAD ruling.

Also - right from the thread you linked:
NAD noted that Mobil markets hydroisomerized basestocks as synthetic in Europe and elsewhere.

Castrol also maintained that basestocks like shell's hydroisomerized basestock are marketed as synthetic in 37 countries, including the United States, and that Mobil's real interest is in protecting its market dominance. The advertiser argued that Mobil, through its alliance with British Petroleum, has also marketed hydroisomerized basestocks as synthetic in Europe and elsewhere.

You are probably absolutely right, and I am likely absolutely wrong :giggle:

I was in France, and was mostly an Elf and Motul guy. Those were clearly labeled 100% synthetic, was it, or "fully synthetic" - can't remember. Hence my respect for any brand that clearly states what group base its synthetic started with, and whether it's synthetic, synthetic blend, mineral, or ox sweat.

And I have zero issues using any of these, as long as I know.

My initial point was that I used one single brand and type of oil for more than a decade, getting 25+ oil changes at $100+ bucks a pop, gladly, i might say, after what I thought was careful research, and that I am unlikely to use it again. I am not blaming anyone but myself. Caveat emptor.

Hey everyone simple enough question that will probably end up being complex. How does royal purple compare to other major players? I have spoken to their tech line before about gear oil. They were super helpful and personable. I've used their gear oil and their synchromax. I haven't used their engine oil but am curious how it compares. I've read elsewhere that it's basically Valvoline with purple dye. Is there any truth to that? Not trying to compare pricing or any of that just want to compare the actual technical performance compare to it's counter parts.

To get that great Royal Purple feel in the seat of your pants new get up and go, it needs their "Synerlec" technology built in. If it has it, it is on the front of the bottle. Their API licensed oils do not have Synerlec. You would need to buy their HPS (High Performance Street) or racing line to get the Synerlec. Pretty pricey oil, but decent. You can get it off of Amazon or at Summit Racing. Some of your big parts retailers can order it in for you but the price is much higher say at O'Riley's than at Amazon.
