I work with a guy who's son works at GM. Today at work he told me that according to his son GM decided to test RP with the idea of disproving the claim that you pick up power from it.

They tested on an auto vette. Dynoed with the mobil one. They then replaced all the Mobil 1 fluids (oil, tranny fluid, rear end lube..) with the RP, they started with a dry converter so they would get true results. They also used the same weight oils.

Supposedly they picked up 14.7 HP from just the fluid changes.

I found this pretty intersting and thought some of you might also...

I can guarantee that you will not see 15 hp gains from switching fluids. RP is a bit more slippery than other oils, and you "may" see ~5 hp from the switch.

can we get some dyno proof or an article for us skeptical ones? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I've been using royal purple in everthing I own for over 2 years. I've pulled apart engines that looked so good, I was tempted to reuse the bearings. This stuff is the REAL deal.

I've been doing a ton of research into oils lately (more than usual) and have found out some interesting info. Mobil 1 is on the lower end of the viscosity scale, so it almost qualifys as a 5w20 oil. Plus it shears back quickly and thins out more. Which is why a lot of people burn more Mobil 1. I now recommend Redline, it's oil is on the thicker end of the viscosity scale. So not all 5w30s and 10w30s are equal, some are a bit thicker (they have a range to qualify as a certain weight oil)

I don't like Royal Purple's numbers, especially it's very low 400F flash point (it's 5w30 is only 395!) Redline 10w30 is 480F, and even Mobil 1 is 455F! So RP can't handle the heat. It's also not a full synthetic either, unless you use their race oils, but they don't have enough detergents (despite what their tech reps say) for street use. Long term use of an oil with a low TBN like that will result in sludge.

I've actually switched from Mobil 1 to Valvoline Maxlife now! It's a partial synthetic (contains between 12-22% of Group 4 PAO base oil, higher than most blends which are 10%) and has a decent 446F flash point. But most importantly, Maxlife contains moly, which is a very slippery substance, and one of the best antiwear additives (Redline also uses it) Maxlife has a great amount of detergents too, so it will keep the engine clean. I'm gonna have this crankcase of Maxlife analyzed after 3k to see how it holds up.

It is, in fact a full synthetic (the 'W' oils are not "race" oil, only the single weight oils are certified as "race" oils by RP. Yet, the Multi-Vis oils are certified as "full synthetics") by RP, and outside laboratories. I have the documentation to prove my assertion. Have you the documentation to prove otherwise, directly form the RP folks?

PS - I know I am contradicting someone beloved and popular (PATMAN), and so, have no chance of convincing anyone. The fact is that I've seen it, and I know the difference between RP on high HP apps, and junk dino. I just hope no one has to find out having heeded bad advice in the arena of lubricants. Thanks for the bandwidth.

I got this off the RP FAQ section:

'If your street products are not 100% synthetic, why are they priced similar to a full synthetic?

The Synerlec technology provides the best protection and performance increases available, however, it is very expensive. We have blended our street oils to exceed the performance characteristics of any other blended or "Full" synthetic. If having a full synthetic is important, we have our racing line which can be considered a "Full" synthetic.'

I don't quite understand how they classify their oil, since to me it seems like it is either dino, blended or full synthetic. Maybe RP is considered a blended oil.

Either way, I use the 5w-30 in my daily driver and am happy with it.

WEASEL

I read an article a couple of years ago where some independent testers changed the fluids in a 'vette like you mentioned. Don't remember where I read it...maybe C&D or Motortrend.

If I remember correctly it was in a '97 'vette and it was not GM that I remember and the HP gain was not 14.7, but 9hp which still is nothing to be unhappy about.

I don't see why GM would have any interest in disproving RPs effectiveness over Mobile 1.

Just from personal experience with RP gear oil, I switched to RP when I added a TA diffy cover in my 3.23 A4. I eliminated probably 99% of all clunks and clanks in the rearend but didn't know which helped the most. Well I didn't have a good seal on the bearing cap screws and the cover kept weeping oil so I changed it but went with Mobile 1 this time out of convenience. All the previous clunks and clanks returned. I'll give RP the benefit of the doubt and put it back in next time.

Guys, I wasnt there to witness this, and I have no idea why GM would care. I just found it interesting like i said...

BTW, according to what I was told, this wasnt a 97, it was an 02, and it was just a week or so ago they did it..

Patman

Just like Gary said, RP's own website admits it's not a full synthetic, and with a 400F flash point, that would be pretty sad if it was. That flash point is sad, most dyno oils are higher. Maxlife is at 446F, although it's technically a blend. Pours like water? Not the 10w30 Maxlife.

Well, I havent done the kind of researching you guys have, but my personal experiences show Valvoline Syntec to last the longest after 3000 miles in my car. I have had a bone dry dipstick after 1 month of using Mobil 1 on 2 different occasions. Royal Purple seemed better at first but I am down 2 qts after 2 months of using it, yet Valvoline never burned a drop even after 4k miles. Next on the list is Redline otherwise I will be trying the Maxlife.

AT 1,500 miles I switched from a pennzoil crap oil filter and Castrol GTX 10w30 to Royal Purple 10w30 and the longer AC Delco ultraguard gold filter. That same day flooring it at WOT, it would smoke the tires a whole lot longer and pull a lot harder. It felt about the same gain as my direct-flo. I'm not using a different type of oil in this car again.
This is what happened to my car, and I have witnesses to it. Plus, my friend with a red z28 noticed a similar experience when changing to royal purple. According to most people though, they say you will notice no difference at all so don't go buy it and get mad at me if you don't see a gain. I did but then again, every car is different

Ok, if this is straight, I stand corrected. I thought false advertising and purposeful proliferation of false information were federal offenses. I suppose this industry shouldn't be any different from any other...

On the other hand, for $4.78/qt, delivered to my door (because I'm lazy), and in consideration of the above-posted link having shown AT LEAST an oil of high quality, I think I'll stay with RP. I still can't get over the condition of the engines in which I use RP. It's just amazing. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

You guys will get to see actual proof of Royal purple at work here in about a month and a half. Horsepower TV just did a feature on my car where the changed all the fluids over to Royal Purple. This included the motor, tranny, and rear end. At the time of the baseline dyno's, I had Valvoline 10w30 Synthetic in the motor, and Redline in the tranny and rear end. I'm not supposed to tell the results, because the show is not airing til the end of June or beginning of July, but I will tell you this, I picked up double digit horsepower at the rear wheels by going with the Royal Purple. I would have never believed it if I wouldn't have seen it myself, especially considering everything in the car was already synthetic to begin with, but it did! I'm now a firm believer in Royal Purple! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

They used 10w30, just to make sure everything was identical. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
