Although i would have to agree Mobil 1 5W-50 or 15W-50 would work absolutely fine in that engine.
I can get whatever shipped here so that’s not a problem. I’ll look into that one.Can you get Total Quartz Racing 10W-50?
Has about 1100ppm of ZDDP.
Think of it as a crew cab 308.Beautiful scenery, beautiful car! I personally like the looks somewhat more than a 308 GTB, GTS...
Cool, M1 15W-50 should work flawlessly in it.Just an update, 15w50 M1 was on sale so I grabbed a bunch. This car never really sees high ambient temps but that exhaust temp gets the engine bay super toasty. I’ll be measuring burnoff but so far all looks good and oil pressure is where I want it.
Seriously though, you really don't need to run a 50w oil unless you are tracking the car...oil pressures will be fine.
Hello! Nice car! If I raced the car, I would put a 20W-50 into it ; usually 20W-50 have very goog NOACKS : no more than 10.
There are a few issues :
1. Larger spreads oils apart the -W- shear down faster. They also contain more VII, letting more deposits while burning. So I would avoid 0W- and 5W-40 oils.
2. The car burns some oil. Minerals burn cleaner ; synthetics let more deposits when they burn.
3. There are cats on the car, so I would prefer ACEA C3 or API SP engine oils.
4. It seems the car sees rather cold climate and is not raced : high-HTHS 30 weight or 40 weight should be enough.
For road use, I would stick to an API SP 10W-40.
If you really want a 50 weight, for reasons above, I would prefer a 20W-50.
I would avoid 20W-60 and larger spread 60 weights, because of VII loads and deposits.
It’s not the *i* really want a 50 weight it’s that Ferrari engineers wanted a 50 weight.
M1 0W-40 should work fine. It's what goes in my '85 QV and seems a popular choice.
..... Any modern oil is better than what was going in it from the factory.
The factory issued an update recommending 5W-40:

The very bottom line of that document says 15w50 is acceptable and since that’s closer to the 10w50 original spec that’s what I’m going with.It seems Ferrari actually recommends using Shell Helix Ultra 5W-40 ('all models'):
I’m not bound to the 10w50 but I do like the 50wt. M1 15W50 was on sale and available here so it’s all good. Again, the car isn’t driven in cold temperatures so even though it’s Alaska, the car is run hard. With ambient temps in the 70s, though it’s not hot, the oil temp does creep with hard driving and that is 90% of the miles this car gets in our short season..
That may make some sense in a hotter environment. However, if you're bound by
Ferrari's original recommendation, why not just run a 10W-50? They still do exist.
I wouldn't though. Remember viscosity means drag and drag means less power.
.
This car has never had anything but synthetic. AGIP “sint” is synthetic.5W-40 would probably be enough for that engine, those 10W-50 Conventional oils from the 70s sheared like there was no tomorrow and probably by 1500 miles the oil had already become a 40 grade.
But i think M1 15W-50 is a solid choice.
