360 f1 gearbox oil

That was my reaction when I saw the blurb about Nulon, too. All of the GL-5 lubes that say they’re good for Ferraris say nothing about the wear or risks to the synchros.

It’s still a question of picking your poison. Use GL-5, which is recommended for the hypoid gear transaxle, and you risk damage to your synchros. Use GL-4, which protects your synchros, and it may not be up to the task of protecting your gears.

I went with GL-4, figuring that modern synthetics, when changed frequently (every year for me), should minimize wear on the gears while helping preserve the much more fragile synchros.

Only time will tell which works better, and having an oil analysis done after extended use of each is a good idea. That will give us better data than what we currently have. Who will do it?

See my post 195 ..basically same question/conclusion

I will do this summer but we need more people

My annual is coming up in May, so I will try to remember to keep some of the old fluid for analysis.

The 360 oil comes out degraded. After 6 changes in 15k miles it now come out fairly clean in my car. Prior to that it had been changed to schedule at least every two years.
So I think oil analysis is probably more relevant if you’ve had the box rebuilt and cleaned.
FWIW I will continue to use a GL5. The synchro’s are inexpensive and can be changed when the box is out for a clutch change. The gears and diff are ball breakingly expensive.

I'm happy to ship you some over if you haven't already paid that exorbitant shipping price

 

Marshall- Thanks for the offer, but have already paid to have it shipped. Will see how it works. Sounds like a good compromise between GL-4 and GL-5 and the synchros on the V12s are tougher than those on the V8s, at any rate.

 

Taz, why are you considering a change, is the Valvoline giving indications of trouble?

 

Jim- No, has worked great, but the note on the container saying not to use in manual transmissions is starting to worry me.

 

Hmm. I may have to re-think use of GL-4! Here is what Redline says about its GL-5.

That all sounds good on the surface. The fact that owners with 30k + miles are saying they’ve had no problems with Redline is good to hear.

I’m a Registered Investment Advisor moonlighting as a Ferrari Hobbyists , so what do I know......

If the synchros are truly cheap to change during a clutch job, I’d rather protect the gears.

 

The synchro’s are relatively inexpensive compared to some of the gearbox parts. It’s still an expensive job requiring specialist skills (about a day on the bench my tech told me) but I’d prefer that as opposed to damaging the box. Ferrari specify GL5 and I don’t believe any tech would advise anything else on a public forum (even if that is what they use with clients).

Just my 2c worth and may not be correct.....

 

Image Unavailable, Please Login Got this in the mail today from the guy on EBay. Will be giving it a go in a couple weeks.

 

Specs on the Rotra LSX look very similar to the Nulon.

Thanks Taz. That sounds good.

 

just an FYI, I spoke to the local ENI/AGIP salesman in New Jersey and Eastern Pa today. He is able to sell me the Rotra LSX 75w90 at $171 plus tax for a case of 12 1 liter bottles ( $14.25 each per liter + tax). Since I am local, no shipping costs.

This is more economical than the guy on Ebay at $37 plus per liter.

This may be an avenue for others wanting to use this product.

 

That’s a great price.....I paid $150 for 4 litres delivered.

Please let us know how to order. This guy can have a good demand here.

 

Is it Taylor oil ?

Dominick,
No it is not Taylor. Direct from salesman.
I'm getting 12 liters. PM me. I'm located in Cherry Hill

 

Sounds like a great deal. Shipping from Australia will get old pretty fast.

 

GL-5 came along as an oil designed for high offset hypoid gears (which don't exist in 360/430 transaxles) and Ferrari said use it. Ferrari also made rigid exhaust brackets for the . 430 and we all know how that turned out. My 430 MT shifts better with GL-4. I doubt anyone would feel a difference with an F1 trans. 360's/430's have a very low offset hypoid gear set transmitting relatively low torque in a relatively light car. I'm sticking with my GL-4. It's still got the same additive, only half as much. The car's a keeper so I guess long term I'll find out.

 

Very interesting. How do you know we have low offset hypoid gears vs high offset? This suggests that use of GL-4 will be minimally harmful to the gears while use of GL-5 is definitely bad for the synchros.

There is a pic in post 79. Very small offset, nothing even close to the 9" in my muscle car. Also Brian's comment in post 81.

 

Thanks for the info. It was good to re-read those passages and it reminded me of the info posted here, which albeit about Corvairs (!), is a good discussion about GL-4 vs. GL-5. http://www.widman.biz/uploads/Transaxle_oil.pdf

Basically it confirms that GL-4 is probably OK for our cars, and less likely to cause damage to gears where the same can't be said for GL-5 and synchros. RedTaxi, you wrote last year you would be putting GL-4 in your 430. Did you? and have you changed it yet this year and done any oil analysis? I'll be doing mine next month.

 

Yes I did. It will get changed after 12 months. (3 months to go) I had read that article. It quotes 2-4 times the copper in used GL5 compared to GL4. In hindsight I should have tested the GL5 that came out after 12 months to get a comparison with the GL4. So probably not much point getting it tested unless someone (maybe you?) can give me a copper ppm reading on 12 month old 1500mile GL5.
