redline gear oil

would you recommend the redline 75w90 NS for street use? I have used MT-90 in all my alfas for years. this is a GL-4 oil that specifically says is safe for brass components. I am now getting some gear noise in 2nd and 4th gears ( no synchro problem). I am thinking of changing to the 75w90 NS before tearing the gearbox down.

Any insight?

Thanks

Other than cost, there is no reason not to give it a try. I use it on one of my two GTA CR transmissions on the street with no issues. This is, however, just my experience.

Now this is an interesting factoid. Could it be that Fiat's traditional distain for Alfa is at work here? But what, as is often the case in the corporate world, that isn't really a hard-and-fast decision? What if we on the bb organized a world wide email-campaign asking Fiat to change their policy and place an order for Alfa syncros? I would think somebody in the corpoate bowels of Fiat probably made that decision and it got institutionalized because nobody challenged it. With a little luck we might be able to change that.

Just a thought.

I didn't re-read the entire thread, but did anyone mention that Alfaholics is selling what are claimed to be proper reproductions of the original synchros? Anyone know if they are different than the other repros that everyone is complaining about? If so, there may not be a need for a campaign.

gl5 gear oil in an alfa

thanks for the feedback. Are there any resources where I could find out if the GL-5 oil in the 75w90 NS is safe for brass components?

thanks again.

From my experience with brass bushings in Ferrari transaxles, even the 90 EP that would turn the brass black, ONLY did that when it oxidized over time. If we changed the lube either annually, or if it was cooked as in racing, nothing turned black. If we let it cook, cool, and cook again, brass got black. If it sat unused, for years, brass turned black. Flush the brakes, and clutch, change the transaxle lube at each oil change or annually, and there were no issues.

flushing

wow! that is a lot of flushing. I don't know if I can meet that level of dedication.

I suggest that you give a call to Redline's tech supports guys. When I called them to ask if NS was appropriate for an Alfa gearbox the guy I talked to knew all about Alfas. Also, another consideration is that NS has been around for quite some time and is regularly used by Alfa racers. That's about as good a field-test as you'll find.

I changed to NS in the close-ratio transmission in my Super last spring. I'd been told to expect a difference but I was surprised at just how much there was. After putting in the NS, shifting effort was dramatically easier, much smoother and quicker both up and down shifting. You can actually feel the difference in how the syncros bite with the NS as compared to regular gear lube.

Actually you don`t have to call anyone. Just read the lable on the back of the bottles!

Yes it is safe to use with "yellow" metals...

Well, you gotta hand it to the Alfaholics guys, they're certainly walking the walk when it comes to actively finding parts solutions, even if it means they go out on their own and actually make the stuff themselves. Now, in addition to becoming lawyers---shudder---I wonder if Max and Andrew also learned to speak fluent Mandarin? :flowers:

 

[mhunger]

NS it is. I'm sold. I wonder what is making the noise in second and 4th. I hope it goes away with a simple oil change. I'm afraid im in for an expensive rebuild.

 

[cowfy]

the price listed for the synchros is 100 bannanas a ring it seems from their site.can any one confirm that?

 

[mhunger]

wrong. 100 *pounds*. that is $162 dollars a piece. quite a bit, but they did have them specially made and all of their stuff rocks.

Syncros

Once you pruchase and install aftermarket syncros and they prove to be less than great you are out all the effort and $$ you have spent.

I strongly suggest you avoid any aftermarket pieces and call Larry at APE, He will sell you as new syncro parts very reasonably. I`ve never gotten a syncro from him that I was not happy with. I will only use OEM parts until someone proves the alternatives hold up in race application.
Too much "great new product" Chinese junk out there.

yellow metal in alfa gear boxes

BTW, Alfa gear boxes *do* contain yellow metal. Not only the forks, but also the bushings. These are copper. See Paul Spruell's web site for an example.

I even used genuine Alfa Romeo syncros ( $265 each) with a Yellow dot on them and had the same failures.
Im waiting to see how the new ones work= someone else tries them.
Amazing how a certain specialist had never had any problems,,and now has a solution.
Why would you have a solution if you stated you never had a problem to start with.

Richard,,are you using the syncros in race cars with high performance engines ?
Sounds like a good solution = larry at APE

I`ve never used aftermarket syncros. And have had no problem.

 

[giulia_veloce]

Well Richard

You do have a great reputation and always tell it how it is,,which is great.
Your advice is to purchase the genuine syncro rings from Larry at APE
As I said before,,I used genuine syncros rings and had problems
The genuine syncro rings had a yellow dot on them.
Do the genuine syncros you use from APE have a yellow dot on them ?
I will still do more research,but will proably purchase the syncros directly from you.
Anyone used the supposedly new generation syncros from a very reputable Alfa Parts Supplier in race applications yet ?

Syncronisers

If you go back to the beginning of this thread, I suggested using the same parts.
And pointed out that perhaps the level of preparation and assembly might, as well, be part of the failures.

However 95% of issues are probably attributable to one problem.
DRIVERS! These transmissions / transaxles cannot be speed shifted.
