3200 GT Rear Axle (Diff) Oil

[tappets]

Chaps,
just happened to see the Selenia "Fluids" recommendation emblem under the hood of my 01 AC and it states 10w/50 Tutella Multigear LS for the rear axle! The manual states 80w/90 LS which is what I would expect. Anyone else come across this in the past? Typo?????

Its just a regular multi plate LSD Terry, any good quality 80w/90 LSD oil will suffice.... don't forget things have moved on oil wise in the last 16 years!

Yep cheers Dave............just a little strange to spot that 10w/50 grade. 80w/90 LSD's been around a long time too, we're only talking 2001 so not really that long ago RE: Diff oils. I have a slight diff whine that comes in around 100kmph/60mph............I do know all diffs have a "Harmonic" noise point somewhere but being a Maserati making sure that the strange Selenia grade isn't diff design specific and 80/90's not to heavy for it!

I used Castrol Syntrax Limited Slip 75W 140 (Formerly SAF-XJ 75w-140) from Opie Oils (on their recommendation) in my 3200GT.

Some do suffer from excessive backlash even from new.. you can check it out by rocking that lovely Aussie built lightweight alloy prop shaft from side to side!

I think we all know that the quickest way to put the forum into meltdown is to start a discussion on oils. I found that out years ago on the now defunct Maser forum when I questioned the use of Selenia "Racing" oil. I back up what Dave has said,oil technology has moved on a long way since the millenium. What was regarded as "Racing" oil has been far surpassed in quality by every forecourt lubricant. Just check out the SAE rating on the package label.
Any diff oil of the correct grade is way better quality than anything made 20 years ago.

Your dead on there mate and thanks.... lets face it all the so called factory approved lubricants are now well over 20 years out of date!

Yep thanks guy's............been running 80w/90 LS, now 75w/150 LS since owning car (2009), just happened to spot this Selenia info under the hood and thought I'd share the Question! It also states 10w/60 for engine which we all know is spot on!

When I first bought my car,I couldn't believe that SAE 60 was specified for engine lubricant. So I asked around the specialist mechanics who advised that SAE 60 wasn't necessary,so I used SAE 30 for some time. There have been no adverse consequences from using normal lube oil. Then I considered the weird way the engine is designed and decided that SAE 60 was probably justified,so I switched back to the more viscous grade. I'm pretty sure those owners who don't do their own maintenance & lube changes have lower viscosity oil in their engines,ignorance is bliss.

Pandora's box? its 10/60 to cover the combination of big ranges of temperature to give the necessary viscosity performance in the hot bits of the engine, I think?. I personally would not use anything but 10W/60. its worth remembering this oil is pumped through the turbo bearings, as well at the engine, which is one of the reasons the oil needs changed so often.

10/60 it is for these old engines...
It's amazing how tech moves on,18years later a modern highly tuned mass produced Fiat 500 1.4 turbo engine producing 180HP only needs 4 litres of oil once a year..

And if you miss a service so what!

Not at Maserati it doesn't. Still nothing significantly quicker than they were making 18 years ago.

Yes well I'll stick to what I've always used in the 3200 diff...........75W/140 LS good quality mineral base, don't need full syn as not tracking the car and change every 2 yrs. Engine definitely benefits from the 10W/60.........oil pressure alone is much more consistent!

I did a major service on mine (1999, manual) a month ago, and used Kroon Oil Gearlube LS 80w90 (GL5) for the diff. Then went on a 6500km Grand Tour d'Europe with no issues whatsoever.
