Royal Purple in your M6?

[The Rookie]

Is anybody running RP in their manual? What are the advantages or dis-advantages of RP in the M6?

[camaro_ss_97_]

well not sure in the m6 but in the a4 i am very pleased

[third_shift|studios]

dextron III ONLY! as advised by the t-56 manufacturer. However, you do have the brass synchros in yours compared to the carbon ones in teh 98-00 :rant:

[pet_monk]

RP make a Dex III equivalant and will work just fine. I was going to use Mobil 1, but my order got cancelled because of availability. So I am going with RP in my 01 SS. For more information than one can handle about oils read the Oil Junkie thread in General Help. Many people have excellent info in there.

[98LSGUN]

Royal Purple all around. VERY PLEASED!

[blackSS01]

Royal Purple all around to. Tranny is perfectly fine. Have about 15,000 miles on the tranny with RP. Very pleased with all the oil, best out there in my opinion.

In 2001 horse power TV took a stock 98 SS with 70,xxx miles on it. Base dyno was 301 at the rear wheel, they drained engine tranny & rear diff and put royal purple in. Next dyno run the car put down 310.7 at the rear wheel. Less friction through the drive train = more power to the ground.

That is such a ridiculously small amount - there is no way you can attribute that to the fluid.

I could run my car on the dyno 5 times in a row, 5 minutes apart each time, and come up with different numbers, that's just the way it is.

Adding different fluid won't change anything. Stick with Dexron III at $3 a bottle and call it a day.

The only gains from using RP will be due to the extra weight reduction seen in your wallet from over-spending .
BTW
All T56s have a brass reverse blocker ring
Early F car T56s have carbon particle-lined rings
Early LS1s have paper-lined blocker rings ( VERY oil -type sensitive)
Why risk damage/ problems? Save money & use a plain old Dex III.

[98LSGUN]

Rookie, everyone has their opinion and a lot of people always think what they have or are using is the fastest or the best. I'm not claiming RP is the best just that I've been using it for 4yrs and have been pleased with my results. The dollar and twenty cents more I spend per qt for a better product I save on in labor because I do it myself. You'll figure out what works best for you in the end.

[BIG D's SS]

:yup:

[Tobynine9]

Wait a minute here. The owner's manual says you don't need to change the M6 fluid. How often are y'all doing this?

[98LSGUN]

You're right you don't have to change it. I did it at 8,700 miles and I have 18,100 miles on it now. Don't plan to do it again.

[GatorSS]

I think the owner's manual also says you don't need to change the plugs until 100k miles, but the stock plugs significantly deteriorate in performance long before that. Although it is tough stuff, transmission fliud does not last forever, but likewise "weakens" with use. Your change interval depends heavily on your driving, but certainly don't let it stay in there forever.

I first ran into RP when a friend began to use it in his race car. He was the only one who could make it through a whole season without rebuilding his tranny...good enuf for me.

[Tobynine9]

Yeah, I know Royal Purple is great stuff. I've used it past cars of mine. But I was dumbfounded when I flipped through the manual of my car for the first time (I just got it a few weeks ago) and it said "not necessary to change the fluid in the transmission..."! I don't think I'll change it. I'm gonna put a few mods into her but it'll be mostly bolt-on suspension bits and other little things. My Vette-lust will take over before I have enough time to really get into anything on the Camaro.

:luvlove: C6...

Umm My manual says its supposed to be changed every 30k for the M-6, sooner if driving in hilly, mountianish areas. I use amsoil everywhere and the only noticable difference for the tranny was a 20 degree reduction in temp

They should of done an oil change to convention first, dynoed it, and then switched to RP.. but like the gal said earlier. Dyno numbers that small change variably every minute

I'll check again. But I'm 99% sure it says I don't need to change it.

I run Mercon V, it has more conditioners than Dexron III. Plus its semi-synthetic. I have run it in my race built T-5 and is as smooth running as can be. I even run it in my Power Steering Pump. While working as a Mechanic at my local Police shop, we had a high rate of Power Steering Pump failures, when I replaced them, I ran Mercon V and have yet to have one fail and still run perfect with 80,000 miles on them. Plus they dont groan like Fords are notorious to do. It also offers superior shudder protection and exceeds GM specs. It doesnt become hard to shift when its 20 degrees outside and the fluid is cold. -Tim

Replaced my plugs with E3.62 and put Mobil One 0-40, RP Syn ATF, and RP 75-140 rear end fluid. I haven't put her on a dyno, but i Swear that she is quicker... maybe no more than stock cause the plugs i pulled out were dead... It was pure luck that that pistons were still firing

[Tobynine9]

I was right. The owner's manual does say you don't have to change it. But I'm going to tomorrow with RP DexIII. After a 4.5 hour road trip today I had trouble shifting into 2nd immediately at the first few lights after I got off the freeway. It got better as the tranny cooled. Time for new fluid. I guess I do too much driving in traffic.

[GatorSS]

Yes, change that trans fluid, despite what the manual says. BTW, how many miles do you have on your SS?

[Tobynine9]

It's got almost 36k miles on it. I changed the fluid today. It still has trouble getting into 2nd gear. It feels like a problem I had with my old Toyota pickup that, when the clutch had worn, fluid had pulled from the reservoir to fill the gap until the reservoir had no more fluid to give and the clutch wasn't disengaging completely thus preventing the transmission from shifting between gears at times while driving. But my reservoir has plenty of fluid in it and, from what I've read, the '01 and '02 cars don't have the hydraulic line restriction that could possibly be the culprit. Anyone have any ideas what it might be?

This is sort of a thread hijack, sorry.

Iffin ya want to go for the really good stuff, be it it's expensive, get red line shock proof.

[bad6as]

im prefer the amsoil line over the rp line, and all the masters have the restriction

[Nate00SS]

Well the fluid didn't hurt.

[Tobynine9]

Yeah, it wasn't the master. It was a shredded 2nd gear blocker ring.

[Silver SS in Germany]

AMSOIL all around. I have been a dealer since 1996. I haven't used anything else since.

[Orange99z28]

i wouldn't do it, i put rp in my m6 and immediately had worse shifting and grinding when going into second in a hurry

[Killer_bluebird]

It's been 3 months since I changed mine to RP Synchromesh oil and have had no problems at all. In the real cold weather it worked great, now that the weather is warming up it is just as good. I do run the Redline Shockproof in my rear end.
