Re: one word,AMSOIL (Jumper506)
Wish someone could arrange to change fluid and conduct before and after dyno pulls. I saw a segment on HorsePower TV that did just that on a LS1 Z28. They used RedLine fluids. They dyno'd an additional 9 RWHP. If true every MN6 vette should run right out and change fluids. That has to be the cheapest HP gain available.

Re: one word,AMSOIL (AFVETTE)
I would be very careful before I followed the self proclaimed experts. Hard to think that the GM guys get up in the morning to go to work to see how they could screw things up. I had 90K on my 2000 and nothing was wrong, worn or broken. Everyone talks about Redline but if you ask 100 people about it I think you will find very few if any ever heard of it, think about it.

Then there are the delco plugs, the leaking batteries, and so on.

Re: one word,AMSOIL (Richin Chicago)
So who will be there if the recommondations are wrong? 90K on the 2000 with no plug problem, improper torque on the positive post stesses the housing. One needs a tad more research on the rearend failures.

Re: one word,AMSOIL (Jumper506)
The ad for gain in HP claim could be true, but remember that could be a very decptive ad. Such as a 9 HP gain over what? They are probably saying there is a 9 HP gain over a standard mineraloil. Amsoil is a synthetic as everyone already knows, so there is a hp gain over using regular oils. but Corvettes come stock from GM with Mobil 1, which is synthetic. Therefore if there was any gain in HP, it would be neglegible is any. Mobil 1 is the default oil for the Corvette, Porsche and BMW from the factories and is regarded as the "best" oil for an automobile. I did change to synthetic Mobile 1 to my 70 El Camino and instantly the Idle RPM went up so that I had to turn down the idle. This showed me there is less friction with using mobile 1. The idle had to be turned down approximately 200 RPM. You would never notice this happening with a newer car because the computer automatically adjust the RPMs.
Good luck with your oil change. :eek:

I believe he was referring to changing the MN6 transmission from conventional to synthetic.

I never "torqued the battery posts down" and I'd be glad to show you a photo of acid oozing out of the positive terminal post. In fact we announced it at our car show last week and several people found it on their untouched batteries.
Do you really think this is good manufactruing practice? Finally GM did go from conventional to synthetic rear end fluid. If you want the TSB I suppose I could dig it up. GM engineers do a marvelous job but they have to pass all their stuff through a very small keyhole called cost and suitability control. I get to talk to a lot of GM track junkies at a track in Michigan. They are intersting conversations. BTW guess what tire I have never seen on a GM guy's Corvette?

Re: one word,AMSOIL (AFVETTE)
Technically I don't see this as a HP gain, but it is actually less of a HP loss through reduced friction by using oil that is more viscous and having a better
lubricating qualites. But what it comes down to is ...YES any hp adavangetage, wether I gain or reduce the loss to the rear wheels is a good thing. The oil ads never stipulate if they do their testing with the same weight oil. as using a lighter weight oil for testing puposes results in higher HP yields, which can be misleading. I don't know what GM uses in the tranny of
the mn6, so I could not comment on any hp gains in switching to "Redline".
I would think that because of "cost" restraints, GM uses conventional tranny oil in the C-5. So switching over to a synthetic would reduce friction and thereby result in less HP loss at the rearwheel or if you care to put it in a
HP gain at the rear wheels.

Well there are a ton of people here including me that had the bottom platinum pucks come clean off of the spark plugs.
I never "torqued the battery posts down" and I'd be glad to show you a photo of acid oozing out of the positive terminal post. In fact we announced it at our car show last week and several people found it on their untouched batteries.

On my 7th corvette and nearly 1million miles without a plug failure, what would you like me to say.
Misadjusted torque wrench at the factory is a bad thing your right.
As far as the lube change, don't know the full reason but Id'ing it as a cause for failures with just a change to syth to fix, that's a long reach.
Only met one GM employee with a Corvette and he was so far up the foodchain he wasn't into changing much. Haven't met any others that owned a C5, most I knew was when I lived in Wisconsin and Janeville was in the loop for GM but not Corvettes. Interesting though when I was in Laughlin for the Corvette/Bicycle thing last year. Of the 100 Corvettes 82 were C5's and only one had a NON Goodyear GMT. Must not have found those guys for the pole.

I don't know many people that have pulled the Delco plugs on a C5 that haven't found some pucks missing if they know what to look for. Did you look at yours? They could of been NGK.
Battery:
Not only is misadjusted torque a bad thing so is a battery that is that fragile. In fact we have no idea that the torque was misadjusted at the factory. Why do you think GM went to a more expensive AGM battery?
Synthetic differential fluid:
What is a "stretch" is to think GM went to a more expensive fluid out of the goodness of their hearts. What other reason other than durability and warranty claims?
Runflats:
Ask Luke at Tirerack what percentage of his customers stay with runflats when they need new tires. The buff and shine low mileage crows will stay with whatever is on the car but most enthusiasts are going to not be satisfied with the ride, noise, and lack of grip. I would guess a few hot laps would convince anybody to change. Same with a road trip complete with an A B comparison.
