I totally forgot to collect an oil sample of the Valvoline Synthetic I had in there for a UOA but anyway, now the Vic has Royal Purple HPS. Since I'm doing a short OCI I left on the old filter... I'm going to do the next oil change at 130K (so about 3K miles) with a fresh filter and a UOA just to see how it goes. Then I'm gonna go for 10K OCIs. Initial observations are the engine seems really smooth and quiet - then again it was fine before. If I really had to guess, sure, it's a tiny bit quieter, but it's hard to tell if it's just my mind going $24 oil vs $48 oil... I'd say the most important part is that the oil poured purple, which is my favorite color...

I have about 12 quarts of Royal Purple 10w-30 to use up. May just use it in the tractor for a year interval. I did use it in my wife's Capri for a 3,000 mile interval and worked just as well as the 5w-30 Valvoline Synthetic I usually use. No UOA's but doubt I need them on my normal 3k or 5k intervals.

And Purple oil is cool. Because of reasons.
 
Why not just got 7-8k miles and put a new filter on it right away? Good and pricey oil, why not make it worth its while!
 
Royal Purple (even API) is one of my (non scientific) preferred oils. Thanks for the oil-porn.

If Royal Purple was cheaper than Valvoline full-syn at walmart, I might use it too. I just see exactly NO justification of the higher cost. If somebody has some reason to use Royal Purple that is sensible & logical, then I'd love to hear it. It needs to be actual, real facts, not marketing emotions.

I was almost taken in by a similar marketing effect: LiquiMoly Molygen is flourescent green, kinda cool, right?! And, it has tungsten FM in there in some unknown amount, so cool too.
Then, I noticed it didn't have the approvals and certifications that other oils have, like the expensive Ravenol, or about any dexos1 Gen2 oil in existence. So, purple or green, the coolness factor isn't a real performance measure of anything real.

I got mine on clearance for $9 per 5 quart jug. Really the only reason I bought it.
 
Its going to be really interesting it looks like a bunch of people bought this on special. Just like I did but I got two Jugs for $20 each. I will compare UOA's when I run mine and see if this stuff makes my Toyota dance and purr. The first indication I suspect is going to be when my Toyota asks me for my first dance on I-5 or I-90.

At 10-15 mph I doubt you will hear much difference.
 
Only thing is RP's regular stuff is vastly different from HPS which is what I'm using in this car... But yes I love the color so much!
 
Honestly the Capri didn't run any different between Valvoline Synthetic 5w-30 and Royal Purple 10w-30. If I didn't know what was in the engine I wouldn't know what was in the engine. Runs really good to begin with anyway. I was using API Royal Purple, not HPS though. Joe Sherman of Sherman Racing Engines has claimed 7 to 10 HP on an engine dyno (not chassis dyno) with Royal Purple XPR over other synthetics, to include Mobil 1. These are A-B-A tests according to him. To me 7-10 hp in a 700 hp engine is within allowable error. If I saw 5 hp on a chassis dyno with a particular oil in my 305 hp car, I would use it. But I'm not one to dyno my oil change. I can take the spare tire out of the trunk at the track and get the same results.

I posted my oil change on a Facebook group of car guys and several people claimed they knew people that suffered engine failure on the track due to RP XPR and that the engines were fine after switching to M1. Who knows if that's true but I'd personally avoid XPR myself... If I ever use up my 10 gallons of random mixed oils in the Escape or the UOAs of my mixed leftovers are too horrendous I'll probably just go back to Valvoline Synthetic or start using RP API... I'm excited to see the UOA of the Edge EP in the Escape currently but I like to support American companies and BP owns Castrol so I probably won't purchase that again.

I have to wonder what the meaning of engine failure is in regards to. Lots of forces at work in a race engine. Oil is an easy fall guy when something happens. Nobody blames the engine builder, especially when he's in the mirror.

Right, I mean, if the first time they did it they have never built an engine before and then after it blows they send it to a professional, well, it had nothing to do with the oil.
 
your motor will be fine,its not a race motor and when a motor blows 90% of the time its mechanical failure not the oils fault.

those facebook groups have alot of idiots so beware

Before, with the Valvoline (and the same Royal Purple filter that's currently on there) I had some annoying rattle on startup. With the Royal Purple HPS, there is NO more startup rattle, even on cold starts. I was under the impression the oil filter was to blame (though it happened less on the RP filter and the Valvoline than compared to whatever was on there from the police department)... so you know what? This expensive oil is worth it for that reason alone - no startup rattle is worth paying a little extra.

But now I want to know how a different brand of oil could reduce startup noise, because like I said, I thought that was due to the oil filter...
