Some it is also subjective. Do you remember the noise exactly after you changed the oil the last time vs this time. Or comparing how its sounds with fresh oil vs used and ready to be changed?

Yes it can be subjective but I gave it over a week and around 300 miles in use. The one thing I love about Royal Purple is that it's stays quiet throughout the OCI.

The only API licensed oil that has synerlec is the 5w40.

I would trust your ears on this.. Plus someone who knows a lot about RP.

Thanks. I do trust my ears even though sometimes I get ridiculed about it here.

I put some Motorcraft in my lady's Camry today and it is running a good bit quieter. I've run PYB, Pennzoil Gold, and Havoline. This Motorcraft is easily the quietest while running oil that's been in there yet. I am pleased.

I do hope that the RP HPS goes on sale at Pep Boys... I've run the API version which was good. But the HPS version with Synerlec is where its at.

^^you can find better pricing online for HPS. For example RP HPS 5w30 is $87.xx for a case by a seller on Ebay. You won't find it for cheaper anywhere. Comes out to $7.30/qt.

I've had the HPS 5w30 in the sump for 2 weeks and both the ticking and clattering are completely non existent. Thus the oil runs a little smoother and quieter than the RP 5w40 which was surprising because 5w40 ran super smooth and quiet in its own right.


Unless you're doing NASCAR type racing for hours it's totally unnecessary. You won't have decrease wear if you do drags or even 20 minute runs on Royal Purple hps oils

When I say this, you know I'm a Royal Purple fan. When VW specified 5w-30, they did not, however, have a low HTHS 5w-30 like RP HPS in mind. Note that the specifications talk about HTHS and not film strength. RP's 5w-40 still has Synerlec, as you're aware.

Is the oil really purple?? yuck...

 

[Garak]

Yes, it's purple, and it's no more "yuck" than the color of other motor oils, really.

Thanks. That was the point that I was poorly trying to make.

HPS 5w30's HTHS is 3.40 to 3.42 cP. Very different from an ILSAC 5w30, still more than the lower HTHS ACEA series oils (which still use advanced additives to make up for the lower HTHS, VW 506.00 and 506.01 come to mind), and very close to the ACEA A3/B3/B4 oils.

As BobFout mentioned and I verified with RP that this 5w30 HPS has a HTHS of 3.5 which is close to what Mobil 0w40 IIRC.

I'm also kinda experimenting with this oil. The last OCI on RP 5w40 I burned 2.5 quarts of oil. I'm trying to see if I burn less with this oil as Royal Purple has told me that 5w30 HPS has much more synerlec in it and nearly 4 times the film strength than 5w40. I shall see how much oil this OCI burns in 12,000 miles.

Lol....when you keep your oil in for 12000 miles it can decrease wear.

Is it 3.5 cP now? When I asked RP tech support last year, they told me 3.4 cP...

While I don't doubt it has more film strength, does it have more film strength under meaningful or accurate conditions found in an engine?

When I talked to them 2 weeks ago they told me 3.5 was HTHS.
I have no doubt that it has meaningful and accurate film strength inside a combustion engine as we have torn down enough engines running on RP HPS and all have virtually no wear within them.

Is this any different then those running a high quality synthetic oil from Mobil, Amsoil, Redline, Pennzoil, Vavoline, Pentosin, Fuchs, Liquimoly, Castrol etc.?

A lot of very high performance vehicles specify the European ACEA A3/B4 LL01 oils without problems.

A highly tuned factory BMW or Porsche probably is a more demanding application than a tweaked Audi.

However, if the RP is working for you, you have confidence in it, and you can afford it; that's what life is all about here in BITOG land.

We tend to see least wear with Royal Purple and Joe Gibbs oils. The others seem to have a little more wear but are all within spec and would lend to a long engine life.
