Royal Purple Racing Oil

STi-Nismo Dood · 02-12-2001, 11:40 PM

I understand that it is recommended for a person that drives hard with a rice car to use 5W-30 SAE Oil, I saw some Royal Purple Racing 0W-10, 5W-20. I know these are hi performace oils, but what will be the consequence on putting it in an everyday driven car?

Royal Purple is one of the best oils out there! If I could afford it I would use it (I use Mobil 1 5w-50)

I use Royal Purple in my race engines and it is fine for the street.,..

I'm still not sure what 0W-10 does??? That spec sounds crazy high performance, but it is the same price as 5W-30. Both are $110 for a case. But what will be the side effects if anyone knows if I use "0W-10".

Eric SS · 02-13-2001, 12:08 AM

Basically, the lower the number, the thinner the oil is. So, a 15w-50 oil won't get up to temp as quick as a 0w-50 oil will but a 15w-50 oil will lubricate an oil better so it will last longer.

What I would do is look at the back of a obil 1 oil container (1 quart) it will show what oil to use in what climate

Even better, get some of each and put a cup in your freezer. 0w- oils will flow more readily at low temperatures than 5w- oils, which in turn are less viscous than 10w- oils.

You live in LA. There is no point to using a 0w since it is never cold when you start your car (before you disagree, I have lived in the Midwest and what LA residents call "cold" is most assuredly NOT cold). All else being equal a narrower viscocity band is desirable. For a lot of the year you can probably use a 10w-30, seeing as at typical LA spring-fall temperatures a 10w flows very easily.

I am not sure about the consequences of running an oil with an upper viscocity of less than 30, and at 10 I'd be getting worried. Are you sure that it retains enough shear resistance at operating temperature? I have yet to see any indication that any EJ-series motor is better off with an oil with a hot viscocity of less than 10. If I were you I would stick to 5w-30 and 10w-30.

OK, thanks for the good advice guys!

As mileage requirements get higher and higher, look for more 5W-20 oils in North America. These are already used in Europe.

The last time i checked on prices (early last year at royalpurple.com) royal purple was actually slightly cheaper than comparable mobil 1 from the nearest autozone.

The reason i checked was because a consultant we work with. He is a rotordynamics specialist (has been consultant on everything from little turbos to pumps used on space hardware to massive industrial gas turbines)
who is also a tribologist (sp?) (study of lubrication and bearings). He was talking to me about it after work one day. he showed me the results of some testing he had done on royal purple oil and also other synthetic and also blended oils. In every instance the royal purple was better than the others and in some tests it was greatly better. He used to use Mobil 1 in all his cars and now uses royal purple. i've just been too lazy to track some down locally to use it in my car.

jlyttle · 02-14-2001, 06:25 PM

How does it compare to Redline?

STi-Nismo Dood · 02-14-2001, 06:54 PM

It KICKS ALLLLLLLLL other company's Oilie a$$, I ordered a case from them online, but I needed a bad oil change so today I went to pep boys and bought 0W-30 TriSyn Mobil 1 anyways! =D, just FYI, I ordered the case of Racing 21 5W-30, can't wait till it comes!

Hmm, are their "racing oils" different from the stuff that I can buy in the store that just says "synthetic oil"?

STi-Nismo Dood · 02-14-2001, 09:16 PM

YES!!!!!!!!!!!!!!!
If you want that its 69 dollars a case for tri-syn, if you want racing 21 its 115 dollars a case. Do you think there may be a difference =D

I found this posted on a previous thread:

Quote:

As a former motorcycle racer, superbikes, I can shed some light on Royal Purple. It is a great synthetic racing oil. But it is racing oil, it is designed for short life high temp. motors hard working motors. The stuff is not designed for everyday driving. If you race or do a lot of hard driving it is wonderful. But beware I personally do not trust it for more than about a 1000 miles. I have had friends in a group that I used to ride with have problems with it, one guy blew his motor due viscosity break down of his oil. He was running Royal Purple.

I ran Royal Purple in my race bikes, but I ran Torco 20w-50 natural in my fun bike, 1998 GSX-R750. Royal Purple was orginally designed for motorcycle supersport racing and only recently within the last five years started doing automobile applications, can't verfiy last statement but heard it from a couple of mechanics on my old race team. Form my experiences with it excellent race oil. If I was to use it for normal driving oil I would be changing it once a month or every 1000 miles. But I know the stuff worked great at 15,000 rpm's on a bike with a 180 hp in 749CC = 43.2 cubic inches of displacement. I would talk to a race shop or tuner before going with any sort of racing oil, it may save you thousands in the long run.
Peace, Erik

Any thoughts on this?

Keiho · 02-15-2001, 01:22 AM

That's the exact post I was thinking about!

I use just the regular synthetic oil...not too sure if I can get my hands on the actual race oil. Will have to look harder next time.

So yea, anyone want to shed more light?

AKGC8 · 02-15-2001, 03:16 AM

Save your money people!

Mobil 1 synthetic(or any other synthetic for that matter) is going to be more than ok on any road car. Why spend 100+ for a case of oil? Its not like its going to give you any more performance, and do you really think it will make your motor last any longer than a regular synthetic. C'mon people, don't waste your money.

harrydog · 02-15-2001, 05:38 AM

I don't think you should make the choice as to which synthetic you will use based on anecdotal evidence. If you really are concerned about getting the best you would need to compare them all using, for example, SAE and ASTM standardized tests. Otherwise, any claims that you hear about should be taken with several grains of salt.
