Royal Purple High Mileage Motor Oil

[fordman65]

Hello all,
I just saw that Royal Purple is now making a High mileage synthetic oil?
Does anyone have any information about that? used oil analysis or other information?

I saw just saw,because I was on the RP website and saw it today. It might have been out and I don't want to bring up a sore subject on the site if it has been discussed already.

Thanks

I wouldnt bother with RP.
Good oil but hugely overpriced.

PP PU and Mobil 1 All the way.

 

[DragRace]

OP wants information,nothing mentioned at all about PU,PP or Mobil.

Hmm, no technical datasheets posted yet. In the past I've found their tech support to be pretty helpful -- send them an email and ask for the datasheet.

The API SL rating makes me wonder if they're using higher ZDDP levels or something like that.

It's definitely a new product -- first I've heard.

Maybe some Synerlec, too! Or, it's just old stock they found in the back and printed new labels for it.

I sort of always thought of RP as a high mileage oil, anyhow. It wasn't because of any ways to reduce consumption or so forth, but that it had (back then) older specifications and was great for an out of warranty vehicle.

I'd be interested to know what the ______ cSt @ 100C spec is.

It has been out for like 6 months to a year.

So you have used RP High MileageX and concluded it is over priced? What did you use it in, how did it underperform for the cost, and what did you pay? Unless you can answer those 3 questions with truthful answers you haven't used it and thus should not be trying to talk people out of using it. Your post is meaningless and typical of the anti RP [censored] that gets posted here if you haven't used it.

Also, what does Pennzoil Platinum or Pennzoil Ultra have to do with High Mileage oils? Neither of them is an High Mileage oil. Pennzoil makes an High Mileage oil but it isn't one of the ones you mention as said. M1 makes an High Mileage oil too but your comment is vague and based on your Pennzoil recommendations I would assume you don't mean the Mobil 1 High Mileage oil either. The topic was RP High MileageX oil. Not PP, PU, or M1. You couldn't even stick to the right oil type. Just another senseless and baseless RP negative posting.

Why do some always have to take every chance they can to beat up on RP here? Man it gets old. The price thing is the most ridiculous of all negatives because myself and others have shown time and time again it is not over priced. It can be had for close to, the same, or even less than the other name brands if you shop for it.

Your oil purchasing options are not limited to WalMart's oil aisle people.

their website says it uses synerlec. I'd assume if its an SL oil, its got higher zddp levels. I'd give it a shot if I could find it cheap enough

 

[Garak]

I haven't seen anything up here. I may have to check with my supplier and see what the price is up here.

 

[901Memphis]

Should be a good product, just waiting on Walmart pricing like the rest of the name brands.

NIIIIIIIIIIIIIIIIIICE!!!!!!!!!!!

So synerlec is back into their just regular oil again,without having to buy the hps stuff.
They've got a 5w30 euro with synerlec which I've got enough for an oil change with.
Maybe I'll use that before the Belgian castrol 0w-40 I have on deck.
I've got enough 5w-40 euro with synerlec for an interval too.
Maybe I'll go purple for the summer then use the Mobil 1 0w-40 I've got for next winters brew.

Why would you want a SL oil? The SN oil is cat safe and outperforms. I guess the old viscosity wars have been settled and now the backwards crowd is hoarding SL and SM oils!

Newer is usually better as a rule of thumb. Especially when it comes to technology. Maybe trying putting in some model A oil in a modern engine one day...

ZDDP levels have decreased but other additives have been added to the mix and when you add in better basestock oils you are looking at great oils. I dare to say that Pennzoil conventional SN maybe better than a SYN SL depending on the application.

Apparently you're uninformed so I'll teach you something so you can take this condescending post and maybe reconsider posting prior to knowing anything.

It's an SL because of the synerlec additive. This additive has proven beyond any doubt via multiple torn down drag racing engines and tear downs for upgrades in various daly drivers that I've seen personally.
So if by going backwards you mean using an oil with an additive that made royal purple famous and is now being put in something more suitable for the masses and longer drains then yes I guess that's backwards.
I've seen and held small block cams that used RP with synerlec for 400000 miles and the cams had no wear to be felt where the pushrod contacted the cam,and the engine still had 190psi across all cylinders. Engine was 9-1 compression and it didn't use a drop of oil. There was a very slight taper in the cylinders however we were punching it out anyways but we could very well have just re-ringed and scuffed the bores and it would have gone another 400000.
Synerlec is something very special. I've seen many engines that used RP exclusively that were spotless and virtually no wear at high miles when torn apart for performance upgrades.
And you obviously don't know so I'll inform you.
Whatever spec the oil meets is only relevant if you've got an engine that's burning oil. Only then will the elevated phos potentially foul a catalytic converter. So no burn means whether an oils SN or SL isn't relevant.
Perhaps you've heard of one of the forum favorites called German castrol. Its a 0w30 that has been SL rated,never being re formulated to meet a new spec.
Why you might ask? It's because the formula is just that good. The guys who use it here swear by it for its many virtues.
And truthfully meeting current SN spec only matters for vehicles under warranty and once the warranty expires many here choose an oil with higher levels of anti-wear agents by going a grade thicker,because 40 grades for example don't have to lower their levels of zddp,or they choose high mileage oils such as defy which,wouldn't you know it is rated SL.
And when you saw the title of this thread did you happen to notice its about a high mileage oil. And since high mileage oils tend to have stronger additive packs that include anti-wear agents that get neutered to meet the SN spec which ends up meaning that these oils have an SL designation due to the elevated levels of anti-wear.
So if by going backwards you mean formulating an oil with a stronger add pack with more anti-wear agents and a bonus that includes seal conditioners and the ability to run extended drains then yup,we're going backwards.
Any other wisdom you'd like to share.

It was always my understanding that just because an oil is SL, that doesn't mean it isn't as good as an SN oil, such as in the area of cleaning or resisting oxidation or burn off. if I'm not mistaken Mobil 1 High Mileage is SL, not because it doesn't do the same things as well as a SN oil, but simply because its ZDDP levels are to high to meet the SN specs, therefore it falls into the SL category. Correct me if I'm wrong

 

[rw19]

High ZDDP levels = early cat death. This type of cat does NOT have 9 lives!

 

[afoulk]

And I think you would have to be burning huge amounts of oil for the zddp to plug up a cat. Has anyone ever seen an instance of this happening? It just like with the dpf filters on newer diesel trucks, I see dpfs get burnt up and melted at work because of faulty injectors or regen issues, long before excessive zddp contamination would plug them up. And they generally have a life expectancy of anywhere between 150,000 and 250,000 miles before the manufacturer recommends having them cleaned or replaced. In my experience, if your burning enough oil by that point to cause problems, your doing something wrong with your maintenance program anyways.

Well let me rephrase that. Cats don't get ruined by the ZDDP levels. They just don't work at peak efficiently and deteriorate slowly overtime. The goal of the SN was to protect the emissions system. High ZDDP levels aren't needed anymore we have other additives in the oil that are just as good.

And as to synerlec. I don't want to comment. All i want to say is why hasnt a major oil company invented something as great as synerlec? Because its snake oil. RP does not have the resources to compete with the big boys.

This isnt a knock on redline or amsoil. I love redline and amsoil. They dont have gimmicky additives they use. They use quality additive packages and great baseoils to make very good oils.

As does RP but the whole purple oil bottle design and "syenerlec" is too gimmicky for me.

Sorry but no thanks.

Yeah and Amsoil uses a pyramid scheme to sell their oil.. PLEASE spare us the drama of the purple hate speech, it's been beaten to death here forever !

Just being pedantic but the pushrod doesn't contact the cam

It'll be some form of HLA/lifter/tappet, either roller or flat. And I've seen similar performance from M1 (minus the bore taper, as 302's and their amazing 3" stroke tend to keep the bores pristine).

Not saying that RP isn't a good oil, simply that we don't know how their non-synerlec products perform in comparison and for all we know, they may perform just as well. IIRC, I believe it was buster who posted that Synerlec is a sulfur-based additive, and that's where the nickname "Royal Sulfur" came from
