Oil question? Who is runing what in a 348.

Redline 75W90NS. Shifts real smooth (er ... for a 348 that is).

 

Well, you should probably take the tech's advice as that's his specialty...but the Superlight Shockproof was the best shifting gear oil that I've ever used.

I'd run it again in a heartbeat, and in fact will be going back to it when I change my gear oil next year.

Pap and I can be the 348 test mules for the shockproof. If anything is going to go wrong with a 348 tranny using it, we'll find it first.

Lightweight shockproof in the box (blue/grey) stuff

 

Bah, what does he know?
Seriously though, who is he and what does he REALLY know about the product? He could be a pimply faced teen that started working there last week. Anyone can read a label and praise to the lord about using it or not using. It all comes to experience with it I suppose.
As ND said, if the gearbox blows up (which I HIGHLY doubt ) then we will live and learn. But I dont really think so. You never know, maybe we are getting excessive synchro wear because of Shockproof oil. Maybe we really have to use NS oil..............but you get that.

 

Btw...........I am about to do an engine oil change. I am switching to Royal Purple 15W40 engine oil.
Redline Superlight Shockproof in the gearbox...........of course!

 

Any synthetic that is on sale. They all work.

 

I have been using Mobil 1 15//50 for as long as I can remember.

 

Dino, You're the long-term 348 man! What sort of oil pressure do you see when cold (at idle and 4000 RPMs) with oil that heavy?


I barely know more than the price of oil per barrel, but after reading AEHaas' oil threads I've been going to lower and lower engine oil weights (e.g. 5w40 Redline instead of 10w40).

My wife's hemi V8 Durango takes 0w20 synthetic! That's so low that it freaks me out.

I'm sure that you need a heavier weight engine oil for the track, but for daily driving would you stick with 15w50?

 

I put the Redline 75wNS in my car with a 1% addition of the friction modifier, and guess what...

I've observed NO shifting improvement whatsoever. I read and I listened to all the praise of this product -- it almost made me believe that it would make the car shift like a normal car! For me, no improvement occurred.

Engine oil is Mobil1 0w-40

 

Amsoil 10W40 and Redline 75W90NS (no FM additive).

 

Get some Shockproof into ya!!
Smooth as butter shifts.

 

Amsoil 5w-30 hi-performance motor oil
Amsoil 75w-90 Severe Gear oil with some slip-lock additive
My car shifts and runs better than ever.

 

I've used Redline's 5W30 motor oil in some Winter months, but it was so thin that I had barely any oil pressure showing on the gage at idle on hot Summer days. So my polite suggestion is to limit 5W30 use for colder months.

 

Recommended! In the meantime, what is your shifting style at those moments when you notice hard shifts?

For instance, do you lift the throttle while the clutch is depressed, or do you keep the throttle pressed during the entire shift?

 

Please do me a favor and for one single shift when cold, don't lift the throttle at all. Hold the pedal down in exactly the position that it was in before pressing the clutch.

Let me know if your shift was smoother or worse.

 

Interesting... I'll have to try that myself. Only catch is that I'm usually flooring it, and the engine will simply bounce off the rev limited until I get it in the next gear & drop the clutch pedal

 

Have used Redline 75/90NS with 1~2% friction modifier for 5 years. Add just enough friction modifier to eliminate differential chatter. Excellent gearbox oil. Specs match well the original Agip product Ferrari specifies. Fellow Ferrari owner Birdman commented my 348 spider shifts as well as his Honda! Of course maybe his Honda has a problem!

 

For what it's worth, I also spoke with Red Line and they told me to use W75-90NS for the 348 trani.

 

Sweet!

Just this week I was thinking about you. I was taking a new prospect for a ride in my 348. He's got a souped-up Honda S2000 and he was stunned by my easy shifts. "How can you do that with a gated Italian shifter?" he asked!

Glad you posted to this thread because I wouldn't have found it to give you a bump, but during that drive I was hoping that you'd tried my little shift trick.

 

Just for you! http://www.youtube.com/watch?v=Fb1YzGcEUCI
