Here's a little feedback on RedLine 75W90 NS. A friend of mine with a 328 had his grearbox filled with it this past week and took a 2.5 hr trip in the car. He reported that it shifts very smoothly, with a clear noticeable improvement. He didn't bother adding any straight 75W90 and hasn't noticed any chatter or problems. So far, very good results. | ||

Even if Mobil 1 turns out to be "safe", I'm absolutely sold on the Redline NS gear oil. I had absolutely NO 2nd gear issue when first driving the car today! Before Mobil 1 gear oil (about a year ago), it was probably like most every other 308. After Mobil 1 it was improved but still an obvious issue. After Redline NS, at least for my car, NO problem with cold 2nd gear. Thanks to Dave S. for helping me get the Redline stuff, since it's not available locally. | ||

Along with some other work yesterday (brake master cylinder, Energy Supension Bushings, and stainless steel/teflon brakelines), I've just switched from Mobil 1 gearoil to Redline 75W90-NS in my 308QV yesterday. This morning will be my first drive to be able to personally test "cold shifting" especially the 2nd gear issue. I'll report back with a comparison later. | ||

Matt--it does seem clear until you read the back label of the straight 75W90, which states that it's not designed to be used in most manual transmissions(!!) That's what prompted my call to Red Line. On the 75W90 NS label it states that gear chatter may occur, but one can add a RedLine additive to prevent that. I believe that that 's what Hans suggested--ie to blend a .5 quart of 75w90 with the 75W90NS. Man , what confusion over oil! The probable truth is that they're likely all good-enough--who knows? I'm interested in hearing people's experiences with this. A freind of mine just had his 328 gear oil switched out to 75w90NS today. I'll ask how it works and will report back | ||

I'm amazed that anyone is putting redline 75/90 NS in a road car, let alone that Redline are reccommending it. NS stands for "non-slip" because it does not have the additives required for most LSDs. Here is what the redline oils website says about the stuff "recommended for manual transmissions and non-limited-slip transaxles that recommend 90 WT oils. Can be used in racing limited-slip units to increase lockup and reduce wheel spin. Street-driven rear-wheel drive cars should use regular Red Line 75W90 or 80W140" http://www.redlineoil.com/products.htm Sounds pretty clear to me although Redline's technical info is kind of lacking in both the technical and info departments. Still, IME 75/90NS is a good oil (it doesn't have the LSD additives because they slightly slow down synchronisation) but you need the additives for a street car. OK - if your LSD is knackered it might help! I used to distribute Red Line and they make mainly (but not all) good products. I have used most of their gear oils in various cars including the 308 where I have tried Redline 75/90 and Redline "shockproof" as well as Amsoil and Castrol and Shell synthetic products. I've never had an oil related problem in the 308 although, perhaps coincidentally, the shockproof oil seemed to leak more than most. I have however seen oil related corrosion of yellow metals in 2 Fiats and one Alfa Romeo (sorry no photos)and a number of years ago experienced problems (twice) with Mobil synthetic gear oil in a Fiat gearbox - the product is different now and I haven't tried it. But there's no yellow metal synchros in a 308 so I can't see a problem there. | ||

>>I would like to know more specifically what element the GL-5 additive is corroding. Is it tin, zinc or copper? << I'd like to see even the tinyest shred of evidence of an eatin up sychro from oil. Pictures will be fine to start. I think the real problem is not the oil at all, but more the paranoia and those who perpetuate it. Ferrari and many Ferraristi just LOVE selling FEAR!!

Here, for reference, is a TR syncro. The same material as the 308 boxes I've done. They're attracted strongly to a magnet, so I'd tend to guess they're safe for GL-5. By the way, I use Shell Spirax 75W90 (full synthetic GL-5). In the 5 gallon bucket, it runs about 6.50 USD a quart. It's GL-5 and it the factory recommended oil for the current cars. I use it in the TR, 308 and my 348.  The color with the digital camera is sort of misleading. It's a dull grey in the non-machined areas, bright silver in the machined/worn areas and has no yellow appearence whatsoever. | ||

Mobil 1 is bad for yellow metals as per the lab tech I personally talked to. I do not know that other brands were investigated this far. In general GL-5 is caustic to yellow metals. In general, GL-4 lubricants are all safe for yellow metals. Redline states on thier website that ALL their GL-5 products are safe for yellow metals. I would assume that there is no problem with any of their GL-4 products. Call them to be certain for yourself. I am not worried. Synchro transmissions have a lot of parts including bearrings and bushings that may contain yellow metals. Only the manufacturer of the transmission would know for sure what the various compositions would be, This discussion comes from the Shell site that states their gear lubes are yellow metal safe. I think that we are all figuring that our transmissions may have these in there. It would be difficult to know for sure the actual alloys used. With that in mind, even though any lube might be OK, I will stick with those that claim to be yellow metal safe just to be sure. For me that is Redline or Shell and possibly Agip since that was spec ed at one time. aehaas | ||

OK fans, let's recap. If I've read this thread correctly the following gear oils are OK in ferrari gearboxes/transaxles: Chevron Supreme LS AGIP Rotra LSX SAE 75w-90 Castrol Synthrax 75w-90 Redline 75-90NS Mobilube Castrol Hypoy/c 80-90 Swepco 201 Shell Spirax Gear oils on the NO-NO list include: Mobil 1 Valvoline Synthetic 75w-90 Redline 75-90 And to make the whole thread moot, 308's don't even have brass synchros. Does this apply to other ferraris, ie, does my '94 512TR have brass synchros and is the Valvoline synthetic I put in 8K miles ago OK? | ||

FALSE ALARM: 3x8 SYNCHROS ARE NOT YELLOW METAL ---------------------------------------------- I just posted eMAIL from Ric Rainbolt saying that the 4 3x8 trans he's worked on did NOT have yellow metal synchros: http://www.ferrarichat.com/discus/messages/112/278650.html?1057153711 So far we've heard from several knowledgable sources with personal experience that the synchros are magnetic and/or not brass or bronze. Unless someone comes forward with direct evidence of a yellow metal synchro, I believe that we should consider this as a false alarm & continue using our favorite GL-5 gear lube. | ||

Here's a response I got back from my mechanic regarding the gearbox and the gear oil that we use. Summary: 1. I currently use Chevron Supreme LS synthetic gear oil, not Mobil 1 as I had previously thought. 2. The syncro rings on at least one 308 gearbox respond to a magnet. It would follow that they're not 100% brass, but could contain brass. Does anybody know anything about Chevron Supreme LS synthetic gear oil? Here's the dialog I had with my mechanic... MESSAGE TO MECHANIC: Sean, There's a question up on FerrariChat regarding 308 gearboxes. Specifically, what material are the syncromeshes made of? Some have said brass, some have said iron. It's very important, since Mobil 1 confirms that their gear oil (the stuff that we use) is corrosive for yellow metals (e.g., Brass). I know that you've got the other 308/288 engine out, and Mike showed me the gearbox. Could you please check on this for me? Thanks, --Mike RESPONSE FROM MECHANIC: Mike, I cannot determine exactly what material(s) the syncros are made of. However, I can move the syncro rings on this 308 gearbox with a magnet, which tells me they are NOT 100% brass. But I have no way to confirm if these syncros have any brass in them at all (I am not a metallurgist, nor is anybody here an expert in alloys.) This is not to say that YOUR 308 does NOT have brass syncros (we all know how the Italians can be in terms of production variances.) One thing is certain: your 308 has Chevron Supreme LS synthetic gear oil, not Mobil 1. Whether or not the Chevron oil is corrosive to brass I have not yet been able to determine. END | ||

Is this the "Gear Oil Of The Month Club"? A few months ago everyone here was raving about Mobil 1 Gear Oil, so I tried it and it seems fine -- I had no problems before, or after. Now it appears I need to re-change it, for fear of future problems. The safest bet to not immediately go out of favor sounds like the AGIP, so I guess I'll try that. Thanks for the heads-up!

Regarding Redline 75-90 and 75-90 NS. The �NS� grade is specifically formulated for non-limited slip differentials/ transaxles. My 348 spider has a limited slip differential/ transaxle. The 75-90 is the recommended product for this application. I researched the Redline product line and found the 75-90 comparable to the Agip Rotra 75-90 LSX. The Agip product is also specified for limited slip, hence LSX, with the friction modifier added, as in the Redline product. My spider shifts marginally better after the gearoil change but the annoying �chatter� is eliminated. Just another data point. | ||

The AGIP is the right stuff, has the additve in it already and is what is recomended for the car. It is fully synthetic, not that expensive, you have enough for several changes and you get the yellow bucket. It is the perfect holiday gift!

To concur with Mike and to warn potential users of Red Line, Ferraris need the 75W90 NS.

I just talked to Dave in tech support at Redline. DEFINITELY recommends their straight 75W/90 "NS" for 308 gearboxes. Won't corrode, and the "NS" means no additives which can otherwise make it "too slippery" for the porsche style synchros to work properly. | ||

I read previous threads that recommended the use of Mobil 1,and with this in mind ordered 10 litres for my 308QV. Since reading this thread I started to have doubts,so today I rang Mobil and spoke to a very informative guy in there Tech Dept.I explained about the worries that are being expressed on this Forum and he informed me that the Mobil 1 gear oil with a GL-5 rating is indeed not suitable,but there is another product called MOBILUBE which is in fact compatable with GL-4 and GL-5 oils,and this also has an additive to prevent the corrosion on the synchros. Whilst on the phone to him I checked the bottles that I had bought and they were labelled MOBILUBE and it states that they are compatable with GL-4 and GL-5 oils and does contain an addative. I dont know wether this is available only in the UK(cant see that). regards STEVE | ||

I'd check their website or give them a call to make sure it's brass compatible. Also note that if it contains too much limited-slip additive, shifting can be difficult. (For the reason why, do a bit of reading on Redline's web site. Their tech guy told me that older Porsche-design syncros (which 3X8 cars have) don't like "friction modifiers".) However, to your point, if it's brass safe, either Valvoline product will probably be just fine. We're picking nits with this other stuff. | ||

I just put Redline 75W-80 lightweight gear oil into my transaxle of my new 575 Maranello with 900 miles on it. Shifting is better. Before, my trans temp got as high as 140 F and now it only gets to 122 F. There is only one source of heat here, friction. There must be less friction with this thinner lube. The biggest misconception in lubrication is that thicker is better. Of course I only drive around town, I would switch to 75W-90 if I was to race the car at full speed on the track. aehaas | ||

Will not harm yellow metals, brass etc. They have found out that phosphates and sulphates that are used in base oil products is what causes the corrosion. Castrol and other oil company are using a new type of inhibitor. | ||

Many GL-5 oils are corrosive to brass syncro rings. If you check the archives, you'll see that someone here called Mobil and verified that Mobil 1 gear oil will eat your syncros. And, no, don't flame. That's directly from Mobil. Call them yourself. | ||

Bill, You can use the Shell Spirax that is suggested for the 355 with a good result. No limit slip additive necessary on any fluid used. Synthetic is just fine and should not have any leak problems. Also, Mobil 1 blue cap 75w90 may be another option that works if the Shell is too hard to get. Best regards, Jim | ||

Being that Agip is not available, what other gear oil is being used. Will Synthetic leak like it did in the engine, or is it too heavy at 75w90 to leak? Is a limited slip recomended? |
