Just did a Royal Purple Oil change, smoke?
 

I just did a oil change on my 01 Boxster S. First time using Royal Purple i went with 5w-30 hopefully thats a wise choice, because after I got home i read about pedro switching to 10 50 to prevent RMS leak.

The main thing here is I noticed black smoke from the exhaust when hard on the throttle. And I never had this before. So im assuming this is a good thing and the oil is cleaning out the internals of the engine, am i correct?

I just did an oil change with 0W40 Royal Purple and I saw no smoke out the rearview mirror, but now you've got me looking.

Could be the fact that the RP is dark purple and not light golden brown like the M1...could be your AOS crapping out on you, or the typical cloud after the motor sits a day or two cold and oil seeps into the cylinders (normal).

I changed my oil this weekend, too. Went with Royal Purple 10w-40 because I drive very little during the winter and it does not get super cold around here. IMHO 30 weight is a tad thin for a 986.

I am not getting any smoke like you described. The engine does seem to run quieter compared to my previous fill which was Mobil 1 0w-40.

:cheers:

Royal Purple is NOT a Porsche approved oil. I hear it is an excellent product, though, and may try it in the future. I am currently using Red Line.

But, only Randal is using the proper Porsche approved viscosity. I would never use a 5W30 in a Porsche engine, and is not an approved viscosity. 10W40 is not approved either, but a safer choice. You will probably notice more lifter chatter on cold start-ups.

And this statement from Violametallic, "... So im assuming this is a good thing and the oil is cleaning out the internals of the engine, am i correct?" is certainly NOT a good thing. You have other issues going on that need fixing.

Here is an interesting oil write-up. I have zero opinion on the findings or validity:

You should never use an anything/w30 in your Boxster.

0w40 is the minimum, 5w40 is preferred, 10w40 is equally good for warmer climates, per the earlier Porsche approved oil service bulletins.

The Timken Falex bearing test has largely been discredited as a valid method of testing oils - the Holden/Commodore magazine that published that article later published a retraction.

What the test shows is how much moly is in the oil - oils with a poor score have little or no moly - oils with alot (Royal Purple, Redline) have the best, etc.

The test can also be skewed depending on how you perform the test. Knowing how moly interacts with pressure and wear surfaces, it takes anywhere from say 30 seconds to five minutes for moly to form a new wear surface consisting of "glassy plates" when then are sacrificial. Depending on the pressure exerted on the torque arm and how fast the load is applied, this will affect the amount of moly wear film and it's load bearing capacity.

Get the 5-30 out of the engine. Pronto.

Excellent! Thanks, Charles. You da man when it comes to oils! Do you have a link to the retraction?

Black smoke is related to excessive enrichment/ fuel.. Not from oil.

What will happen? This is the first time I used the 5 30.

Where can I get the Royal Purple 0-40?

I have seen it at napa, do a search of autozone, and the likes and you should find it.

In the mid-west O'Reilly's Auto parts is listed on Royal Purple's website as carrying 0w-40. Don't know if you have them out West.

Go to RP's website and do a search for a location. They will not only tell you who carries their products, but which products the vendor sells.

I've looked at Kragen's and Napa with no luck and no registered RP dealer around here has 0-40 only 5-30 and 10-30...

Check out this link on Amazon.com. Shipping is free on any order over $25. Also Pep Boys will special order any RP product but be prepared to pay a premium.

Let's not hi-Jack the thread! :troll:

Royal Purple gets a $2-3/qt premium for the 0w40 and 5w40 over the 10w40.

I'd only use the 40 weight oil in my engine. Porsche never recommended the 30 weight oil. Oil that's too light may not have strong enough film strength and will reduce system pressure.

If the smoke is black, it's a fuel related issue, as stated earlier. Burning oil is blue.

To be honest, nothing will happen than is bad for the engine.

Here's the link to Royal Purple's tech sheets for their engine oils:

Some important numbers to look at:
Flash Point, Fire Point, cST @ 100C, SSU @ 210F

The Flash and Fire points will tell you how hot the oil can get before it will start to break down.

The viscosities tell you how thick the oil is at the testing temperature. The higher the number is, the thicker the oil is at that temperature, and for the most part, the better that oil will protect your engine when you get it good and hot.

Your 5W-30 oil will most likely be fine if you are just driving the car like a normal person. If you track the car, or abuse the drivetrain for really long periods of time, you run the risk of the oil breaking down in the critical locations, like the piston ring to cylinder wall area, and the connecting rod bearings.

You might want to run this oil change only 5k miles.
If you want to see if you can use the oil from now on, send off an oil sample to be tested at 2500 and 5k mile intervals.

BC.

Given the price of the engine vs the price of oil, I am not sure I woud be comforted by a statement that my engine would 'likely be fine!"

But, I am risk adverse, in general.

This is absolutly horrible advice, and shoujld not be followed. In fact, Bladecutter should delete his entire post. Mr. Navarro, one of the experts in the field, clearly states not to use that oil viscosity. Porsche says not to use that viscosity. Other Forum members say not to. But, BC thinks it is just "fine".

W R O N G !!!!!!

Looks like im gonna get that oil out ASAP. My ABS light came on for no reason and the car start to fell different kind of sluggish/ hesitation. I dunno whats going on but the car is parked and im getting that damn oil out. 100 bucks down the drain, literally....

Also, I just put in a new OEM oil filter in yesterday can I reuse it? or should I just order a new one?

Between the smoke and the problems your stating, I don't think the oil is your problem. Could be a Mass Airflow Sensor issue.

Well, you could run you used RP in your lawnmower. I've been using their 5w40 product as it's acea rated, the car runs fine on it, but I'm considering a switch to Redline.

Royal Purple used to claim ACEA ratings, but then when challenged on that fact, their marketing department changed the claim to “using ACEA approved ingredients”, until ACEA stated that they only rate finished products, not components, and that all products that are required to be tested by a third party (independent) lab; after which RP finally admitted they had lied and had never submitted their products for ACEA testing, claiming that “because their customers are mostly US based, ACEA testing is not important.” Right; they get caught lying, and then say the ratings they so wanted to promote are “Not important.” Interestingly, they still publish some tech sheets with marketing employing purposely vague or deceptive verbiage such as “exceeds ACEA warranty requirements”, which is nonsense as ACEA has nothing to do with warranties, only the performance ratings of oils, and RP never defines what “exceeds” means. So they continue to play the marketing hype game rather than focusing on their products. Based upon their ethics, and UOA testing of their products (which demonstrated the poor performance of their products) , I wouldn’t subject my lawn mower to RP stuff, plus you can get a Hell of lot better oil for a lot less money................

And, by-the-by, Red Line does not have ACEA either, but at least they don’t lie about it……….

not to add fuel ( oil? ) to the fire but...

last month i switched off of the mobil 1 0w-40 to RP 10w-40. the week after the change i took a road trip and put around 3500 miles on the car in a little over a week. in total i've now put over 5k miles since the oil change. the first few days there was some smoke on start up, not a lot - more like a little puff. same as with the mobil 1, btw. since then the only time i get any smoke is when the car has sat for 3 or 4 days without being started. again small puff and then it's gone. smells like fuel not oil.

did i get any extra HP ( as RP says )? nah. seems to drive and run like it did before only a little less ticking noise when it's idling. will i use RP on the next change? no. i'm going to try something else.

the general consenus seems to be NO on mobil 1 and NO on 0w and NO on -30.

some people like castrol syntec, some people like RP, a few people stick with mobil because "that's what porsche puts in..."

Go with Total Quartz Energy 9000 in 5W-40 and you and your energy will be happy.

Switched back to mobil 1 0-40. No more royal purple for me, not worth the hype.

Wow, I didn't realise all this, I'll do some searching on my own and re-evaluate my decision.

I have been using Castrol Syntec 5W-40. I like the price too, a bit less expensive than M1.

Switched to Castrol Syntec 10W-40 last oil change.

So far so good...

Curious - Do you still have smoking and running issues?

not anymore after the switch

So you change the oil and the ABS light went off, the car stopped smoking and the car stopped running "sluggish"?

ABS had nothing to do with it, it was just coincidence. But the smoke and sluggish/hesitation problem went away.
