I think it took awhile for the pennzoil to soak into the syncros, it's getting better all the time.

Based on these comments, I'm a little confused. I've been here at CF for 9 years, ever since I got my '01 coupe. All that time, the general comments were that syn lubes were superior to normal lubes, and most of the banter was whether or not Amsoil, Royal Purple, or RedLine was the best product to use. Based on the recommendations here, I put the RedLine D4L in my car 17,000 miles ago, back in '02.

Now, along comes Pennzoil Synchromesh, a non-syn lube, and it's better??



FWIW, I do have the Pennzoil Synchromesh in the transfer case of my GMC 4x4....

I am running Amsoil in mine right now. However, when a friend had his tranny fluid changed the tuner said he has had the best shifting with standard (non-synthetic) fluid. I have been following this thread with keen interest likely for the same reasons you mention in your post. If the shifting is smoother, I may give it a shot in the spring but would like to see feedback from others who have switched from synthetic to this fluid.

It does defy conventional wisdom. Not sure if I'm a believer yet though...I'm going with Amsoil on my next fill.

I think I'm going to try the following soon:

Trans: Amsoil ATD
Diff: Amsoil Severe Gear 75-90

Just looking for an online procedure, and required hardware to do it right in my garage.

How much of each will I need ?

Trans: 4.1 qts Actually 1 gal will do it as you can't really get all the old fluid out.

Diff: 1.69 qts
Reminder: Severe Gear already has the limited slip additive in it. Do not add any more additive UNLESS you get gear clutch pack chatter when cornering. If you should experience some clutch pack chatter, add only just enough additive to stop it. Do NOT just dump a full 4 oz. bottle in.

Do your self a favor and buy the Amsoil hand pump kit. It comes with 3 different length suction tubes for use in multiple sized containers, including the 1 gal size. You'll thank me.

Thanks !

I've read that those who still need to add some start at half a bottle (2 oz) and then do the figure 8 routine to work it in.

Default Pennzoil Synchromesh

I've refilled with RedLine just after I took delivery, tried it for around 40,000 miles, in my 99 (53,000 miles total) and noticed it slowly got harder to engage each gear. I drained and refilled with fresh RedLine and no change.

I installed a Hurst right after I took delivery of the car.

I switched to Pennzoil about three years ago and noticed a big improvement. I was becoming more and more unhappy with the shifting with the RedLine and now, with the Pennzoil, I don't even notice it.

I have Amsoil for the next change just to try it but I don't expect any improvement as how can it get any better. I've had RedLine in the differential from the first change and it's got about 50,000 miles on it. Amsoil going in there too, just because I have it.

Would be interested to get your feedback when going from Penzoil to the Amsoil since I have run the Amsoil since new in the tranny.

Check Amsoil's website. It's on there.

Like I said, the SVG already contains the proper amount. Do not just add some of the additive ahead of time. ONLY use additional additive if you need it. Very rarely will differentials need additional. The additive is sold separately to be used with those gear lubes (of any brand) that do not already contain it. Too much is not a good thing.

It's like I said in an earlier post that I talked with a Tremec service rep and he said that they recommends Pennzoil Synchromesh. I too asked about synthetic oils and he said they were too slippery for the syncros to work properly and that with time the shifting will get harder. Even GM changed the recommended oil from dextron III to a heavier oil that is the same as the Pennzoil but they charge twice as much.

GM discontinued licensing ALL Dexron III, and there had to be an acceptable replacement/substitute. That's the reason.
