Royal Purple-----Is this oil or a Modification?

[Jacko3]

Tampa:

On the label of Royal Purple can, it says that it should be used for engines that meet the API SL standard. And on the can, it seems to suggest that this applies to vehicle models from 2004 and up. This would probably include 03 + G-35 and 350Z engines.

So, it would not be adviseable to use RP in your Jeep. Other issues can erupt form its use in your 89 Jeep. I won't even try RP in my 1993 Little Nissan either. So, stick with whatever you are already using in your 89 Jeep. Your Jeep engine was probably certified for an SJ, SH, brand of oil, which are much older than the SL certified engines.

Its not that RP won't work, but you have to also consider the effect of RP on bearings and seals for those older engines.

Maybe its that i always drive my car hard unlike some women aka you on the forums and dont notice small gains. And you cant honestly tell me that you felt a 4 or 5 HP gain in your car. Yes I read the other posts and watched the horsepower vids. But they were getting the HP and Torque right off the crank and not from the wheels where the power really counts. Not all cars are the same and operate a bit different than others. Sure the engine will probably notice a change. So before you accuse anyone of being a "tard" maybe you should know what the hell your talking about first.

[BigMACKenzie]

hey smockers, yeah it was totally necessary. there was no reason for him to crap all over the op's thread with his stoopid "well I didnt feel anything" post. It was negative and nobody benefited from his angst. Morrison, way to take the high road and call me and everyone else a woman. Your post shows you dont even understand parasitic loss of power from the drive train AND that your a prick. If they measured Hp at the crank before and after, it doesnt make any diff. Its called science and logic, try it out some time. And now to break your streak i am actually going to respond to your post instead of just spazzing and being a troglodyte misogynist a-hole. Can i feel 4-5hp? probably not, can i read a dyno and do math? hell yes. Okay so there isnt a dyno for putting RP in a 93 ka24de or whatever, /cry. if they are advertising %8 hp gains you can probably expect somewhere between .5 and %8 realistically? do you have to know EXACTLY what you are getting...you are going to have to do it yourself. RP is teh ****e, but not the only ****e. Dont knock somebody's product bc you have a bug up your butt. $7 something a quart works out to right price to pay knowing that my engine is oilified properly and can take high rpm abuse

*SIGH*

Can we please keep this thread civil??

KTHX

[G37 Man]

I hope someone does a dyno test with RP in a G37 soon,that is all I want to see.

Thank You All Again for your input.

[BigMACKenzie]

Sorry G-Whizz, I just hate it when i leave the 240 forums to talk to ppl about relevant, interesting stuff just to have someone take a dump on the floor right before I get to speak my piece. hey G37 man, maybe you could pool together with some other owners and have someone(s) with a stock G spend some time on a Dyno and two or three diff oils in them. pass the hat around to pay for dyno fees. I don't have such a boner for exact numbers but I can understand where that is coming from. it makes sense

[smockers83]

*SIGH*

KTHX

Which was I asked if Big Mac's response was really necessary. And to Big Mac, he's not really crapping on his thread. He simply stated an opinion based on an experience and it does have some merit to it. Are you actually going to physically feel the gains of 8 HP when you already have an engine producing 280+ HP? Probably not, its probably right at the minimum of the "just-noticeable difference" under Weber's law, in which you have to factor in the initial stimulus of power. Someone who is driving their car to the limit won't feel it as much as someone who isn't, if they feel it at all.

There is obviously "scientific" proof that RP gives HP gains, but 8 HP at the crank translates into ~6 HP at the wheels. Now that makes the chance that it is noticeable even less with the definition of noticeable in our case being the butt dyno. Maybe on zozo's Honda for sure that he likes to post pictures of, but that's about it. So he has all the right in the world to say he didn't feel it, because he probably didn't. So you can keep your spasms over in the 240 forum so that it remains civil here. For the record, I do believe RP is superior to many oils, but not so much so that I have to freak out on someone that said they didn't feel it, especially when compared to other synthetic oils (the tests done with RP used regular dyno oil for the base line).

[BigMACKenzie]

it wasn't that he didn't feel it. its that his statement was, if he didn't feel it, then it wasn't there. Its poor logic and unhelpful. 8hp becomes 6hp whocaresthisispointless. again, you are trying to argue with me instead of listen and respond. All I was trying to say is that to answer the general question "Is RP better for me than cheaper oils" the answer is yes, with caveats of course. If RP is better than other oils his comment about didn't feel it= does not exist is even more asinine and wasted breath than before we got to that point. I'm not saying its fairy dust, im saying it unhelpful to others to post factually wrong things/monuments to broken logic in this thread. also didnt i just call him a tard? If you think your not a tard, prove me wrong and show how much RP sucks, not call me a girl. I didn't know we got our feelings hurt so easy...

[smockers83]

Eh, I guess I read it differently than you did. Oh interpretation on the internets.

[morrison82]

My bad bigmac I took it a little overboard. Sorry. But when someone puts there opinion on the threads when asked for it and someone belittles them by calling them a tard, yeah it made me a little mad so sorry. Im not saying RP is a bad oil, when I know it is the best on the market from other conventional synthetics. It has been proven. In my opinion, I seriously did not feel a 5HP gain in my car. It is a great oil to put in any performance car such as the G's. I would recommend RP to anyone who would not mind dishing out a little more cash for it. As I said I'm sure my car noticed the change in oils as a result the engine will perform better and hopefully last a little longer. I switched to RP from Mobile 1 and will not switch back even due to the $$. And I agree with the people on here. Oilification!

[psicho]

Let's keep the mis-information to a minimum. There has been no evidence offered of any gains (8% hp, 8hp, 6hp or otherwise) by using Royal Purple over any other synthetic.

Don't get me wrong, I use synthetics in all my cars, but I'm not drinking the same purple Kool-Aid as many others on these boards.

[smockers83]

Over another synthetic, no there isn't. Over conventional dyno oil there is. If you refute the claims and claim bad data, show evidence otherwise.

[psicho]

Over another synthetic, no there isn't.

My point exactly. The O.P.'s comments are diametrically opposed to this statement, and later posts seemed to hang on to the mis-information espoused by the original post.

Oh, Royal Purple, how hast thou become my greatest friend and confidant---don't ever leave my car engine, and send the angels of performance to help tune or detune Psicho's thoughts about you. I love you RP because you make my baby scream. Psicho, I think I am making 1000 horspepower from using RP, only when I make love to my baby. You wanna join the fun, there is room for another?

[toddnos]

anyone have any thoughts on a motors seals conditioned to conventional oil switching to a synthetic like RP having detrimental issues? or what about switching back and forth from conventional to synthetic as available funds may dictate?

[smockers83]

Detrimental issues? No, you shouldn't. Modern materials won't be too affected. As for switching, people in the high latitudes where winters are very harsh switch between conventional and synthetics based on the season--conventional during the warm months, synthetics during the cold, winter months.

[Jacko3]

Hey guys:

Check this link out. http://www.performanceoilnews....shtml

It seems like for racing and extreme perfromance Royal Purple and Mobil 0W-40 which the GTR uses, are great. But for regular applications, other oils in that test seem to be great. And check the horsepower data of the Royal Purple and Mobil 0W-40 at different RPMS Kind of like what I said in my previous RP write up.

[Tampa G35 Sedan 6MT]

Nice find... I think Im going to try M1 0w-40 next.. that must be some good stuff!

[awdjdmtalon]

Well I used RP in the Wifeys Xterra this last oilchange. She has driven a tank full, and quess what. NO improvement in MPG. W/ M1 she was getting 15 mpg. And w/ the RP she got 15 mpg. No this is just the first tank ful, but I doubt it will improve the mpg.

And I know that she hasn't changed her driving style. She could drive Mrs Daisey. I have to flog the X once a month just for good measure.

So unless I see any gains in MPG over thenext tank full, I will call BS on "RP increases fuel economy".

I did drive her X this weekend, and I noticed no increase of HP either by my ever so sensitive butt dyno. Nor have I noticed any smoother Idle.

Long and short of it. Her X has shown me no reason other then "protection of the engine" to run RP over M1.

[Jacko3]

awdjdmtalon:

I wouldn't disagree with you too much as far as improved gas mileage. In fact, in my write up, not once did I mention improved gas mileage as i did not feel there was any improvement on that account when compared to Mobil 1 EP Synthetic 5w-30. Much of my comment between RP and Mobil 1 EP Synthetic centers on increased horspower over 4500RPM, cooling or temperature reduction, and internal cleaning effect. When I wrote my comments, I had no idea there was a study that was done posted on the internet. I only came across the research after the fact. The data proves much of what i had earlier written and experienced. And just like you, I doubt there is any improvement in gas mileage between RP and Mobil 1 Synthetic EP 5w-30. In addition, with RP, I noticed the car experiences slightly more heat soaking much faster than Mobil 1 EP Synthetic 5w-30. Again, I beleive Mobil 1 Synthetic EP 5w-30 is slightly better at heat dissipation than RP. So, for someone driving their G normally and on a daily basis, I think Mobil 1 Synthetic 5W-30 or Mobil 1 Synthetic EP 5w-30 works just fine. However, anyone who races and flogs their car routinely, I seriously advice the use of RP. The smnall disadvantge that RP might have is no where as important as the benefit it provides to the car over a long period of intense useage.

My recommendation is that, for daily, occassional intense, and non-intense use, Mobil 1 Synthetic EP 5w-30 works just fine for our cars. However, if you are a hot head at the steering wheel like me, and love pushing that engine to 6000RPM everytime you get into the car, my advice would be a to use RP or as the internet link suggests, Mobil 0W-40, which is what apparently, the GTR uses. I have no reason to doubt the information on that link as I have earlier written something similar prior to discovering the information on that link.

The link clearly says in conclusion, "In the case of a pure performance or race engine where power is priority and oil changes can be frequent, the 0-30/40 oils such as the Mobil 0-40, Castrol R, or Royal Purple would be best suited. However, for regular street-driven engines, it would be better to look at an oil with a good service interval." I agree completely with this assessment. And by frequent oil changes, i suspect the link means changing a synthetic oil every 3,000 miles or less, when in fact synthetic oils can go for much longer in a normallly driven car---up to 10,000 miles. Again, this may also besupporting my 3000 mile oil change matra with RP, since I flog my car all the time. This link also suggests that maybe as our engines age, Mobil 0W-40 Synthetic oil maybe a good idea. I personally wouldn't recommend going beyond a SAE 30 grade oil in our engines when the car is still relatively new. I hear some use the SAE 40 grade oils to help reduce oil consumption in our G. I certainly would consider switching to Mobil 0W - 40 once my Gs engine approaches 100,000 miles on the odometer. That is still many years away from now.

Of course this info is for the VQ35DE in the G-35s. The VQ35HR engine in the G-37s and newer 2007 and 2008 G-35s, is another matter altogether.

jacko. I know you never said anything about increased fuel milage. But RP claims it on the bottle. And I don't imagine you are too worried w/ that anyway. You "DRIVE" your car.

As for any power increases over 3k on the Xterra. I couldn't tell you. I will have to flog on it this weekend and report back.

I also did some checking tonight. Infiniti calls for a API rating of SL and one other. (forget at this moment). M1, M1EP and RP all conform to this standard.

As for the RP being able to last longer under harsher driving conditions, I don't know. I can tell you this. The owner of the Civic time attack car I crew for did his own oil experiment. He has always used Castrol GTX in his car. (GSR Turbo making over 270 whp) We change the oil before every event. And after a year of me naggin him to switch to synth. He decided to try something.

We did all the normal prep. Drove the car to the track, ran the event, then back home. About 300 miles total. (80 to the track, 140 on track, 80 back home) Took an oil sample of the GTX and sent it off for analasys. Came back, and said the oil showed break down of an oil that was driven 3000 miles. I foget what all the important info was about particles and such were.

Next track weekend. Did the same prep. Only this time we had been running Amsoil. (ran it for a month before, changed it and went racing). Same mileage, sent it off. Got it back. And it showed the same results. The oil lab even said that the Amsoil was no better then the GTX, and recommended to continue running the GTX.

Just some food for thought. When he gets back next week from SEMA and the Super Lap Battle at Button Willow, I will try to get all the acurate info as far as paritcles and amount of breakdown.

[Jacko3]

Very interesting. What year of Honda civic was the car? Was the GTX flushed out of the engine first with a 15W-40, before Amsoil was used? I ask because the Amsoil could have been contaminated with residues left over by the GTX. In addition, if its an older model Honda Civic engine, certainly a GTX would have been just as good. Nonetheless, this whole stuff about oil has been very enlightening and interesting . What do you think?

It is a 92 civic hatch w/ and Integra GSR swap(fully built) and a Full Race turbo set up. AEM EMS, Tien Coil overs w/ EDFC, full cage........

Yes we flushed the oil before the Amsoil change. The interesting thing about it, is that both oils broke down the same amount under the same conditions. So we only use GTX in the car now. Same protection for less money.

What do I personally think? Well I see the affects everyday of what dyno vs synth oil have on cars. And I belive that synth. is FAR superior to dyno oil. I have pulled valve covers on the same year and relatively same mileage Passat 1.8T's. And the differance is AMAZING! The dyno oil cars have a golden glaze on the entire top end, and slight sludging. (on cars that regularly changed their oil) and very heavy sludging on ones that don't.

As compaired to the synth oil cars. The entire top end is clean and looks virtually new. Even the ones that do not get the oil changed as often as they should are still cleaner then the dyno oil cars that do change oil when recommened.

awdjdmtalon:

Excellent info. Thanks a lot. Those 1990 model integra engines were so good that the Wallstreet Journal actually had an article on the 1990 models Integra at one time, describing them as one of the strongest 4 cylinder engines out there. How has the Acura TSX and RSX engines held up against those 19990 model Integra engines? i also wonder why manufactueres stop making cars with proven and strong engines, in their desire to push out newer models of their auto line up. Why do they do this? For example, Acura probably stopped making cars with their GSR engine and Nissan is probably going to stop making cars with the VQ35DE engine pretty soon. By the way, my little nissan--my second car, uses Castrol GTX 20W-50. It has been using Castrol GTX 20W-50 for over half its life--engine runs great---has to run for about 30 minutes or more to even reach operating temperature. Great oil!

[pnk4pnk]

How often will you change your oil now that you use Royal Purple? Also did you do a oil flush to remove all of the 5-30 you could? If you change to synthetic oil can you switch back to Reg 5-30? thank You

[Jacko3]

I used Mobil 1 EP 5w-30 Synthetic before i switched to Royal Purple 5w-30 Synthetic---no need to flush the system since i was still using the same grade of oil--this is in my G-35 Coupe. I have never used dyno oil in my G except in the old oil consuming engine that was previously removed. However, my other car---my little sweet nissan, uses dyno oil--castrol GTX 20w-50. I have no plans or intentions of ever using synthetic oil in my little nissan.

I will continue to do a 3,000 mile oil change even with RP, except God personally comes down from heaven and tells me, "my son, its okay to go beyond 3000 miles on RP".

[pnk4pnk]

Thank You for your quick reply. If I change to RP should I do a oil flush as I have never used anything but the recomended oil?

[Jacko3]

Nope! The recommended oil or what Infiniti uses is a blemd of dyno and synthetic oil---I think they use Pennzoil. It works well with synthetic oil, and so long as the grade you are using is an SAE 30 grade. So, changing from blend to full synthetic without flushing, is okay. By the way, how many miles do you have on your car, and what type of G do you have?

[06x]

Let's keep the mis-information to a minimum. There has been no evidence offered of any gains (8% hp, 8hp, 6hp or otherwise) by using Royal Purple over any other synthetic.

Don't get me wrong, I use synthetics in all my cars, but I'm not drinking the same purple Kool-Aid as many others on these boards.

Thanks for clearing that up
