Use an ester based oil. I use Millers 5/40 nanotech stuff, never scrimp on oil of tyres I say.

Try Opie Oils online, there the best. Or look for posts on here by oilman.

It depends if you do a lot of stop, start city driving as oppossed to highway driving. The latter placing less stress on the oil.

Stop, start city driving places more shearing stress on the oil every time you accelerate from stand still. Should this be you then use the oil recommended by Alfa in this case. If not, and the majority of driving is done on the highway then maybe you can use something thinner as a lot of people have done here.

Hi

I would use a 5w-40 synthetic.

5w40 Engine Oil

Out of those, the best ones are the Fuchs/Silkolene Pro S, Millers CFS/CFS NT, Motul Sport/300V, Red Line and Gulf Competition. The Motul 8100 X-Cess, Millers XF Longlife, Castrol Edge/Magnatec, Fuchs GT1 XTL/Supersyn, Gulf Formula G/ULE, Shell Helix and Mobil Super 3000 are good, cheaper alternatives.

Cheers

Tim

A search on Castrol's web says
Castrol EDGE (Ti) 10W-60
Motor AR 16102
I believe that a 5W-40 is too thin for the Alfa Bosso V6s. It is after all a design of the late '70's.
For the later 159 3,2 JTS the web says
Castrol Magnatec 5W-40 A3/B4
Motor 939A000

Hi

Sorry, I should have checked before, but what size engine is the GTV? 3.0 uses 5w-40/10w-40, 3.2 takes 10w-60.

Cheers

Busso V6 originally used 10W-40, so 5W-40 will be even better for engine health, because it provides better cold-start protection.
First number represents viscosity at low temperature, and second number at high temperature. So 5W-40 and 10W-40 differ only when cold, 5W-xx being less viscous circles through the engine quicker after starting the engine cold.

Later versions of busso, like 3.2 had factory prescribed 10W-60 grade, I do not really know why they changed to this grade, as internally 3.2 is almost the same as other 24V versions (it has different camshafts, crankshaft and conrods thou, but still pretty similar).

I am using 5W-50 Motul Sport (ester based full-synthetic) in my 3.2 busso.

Alfa's recommendations for the 916, 147 and 156 changed in the early 2000s from 10W-40 to 10W-60.
Some of the TS and especially JTS engines had some oil consumption. I don't remember if V6 Bossos also had oil consumption.
I'm sure that tolerances in these engines was made to 10W-40.

That's interesting. Where did you find the updated recommendations so we can check what our cars should now be using?

That was quite early in the models life. I bought my 156 TS 2,0 (1999) in 2002. I got a copy of the invoice (2001) for the last service it had before I bought it which was done by an very reputed Alfa dealer. I could see that it had 10W-60 oil in the engine.
At some later point in my ownership I had the cam seals changed at a cam belt change. The mechanic said that the 10W-60 contained less purifying ingredients than the long life 10W-40. Since then (about 80k miles) I used 10W-40 and changed once a year.
About 10-20% of the 2,0 TS engine had oil consumption, a fair bit of the JTS had had. The 1,6 and 1,8 TSs usually didn't consume any oil.
I don't know about the 3,0 and 3,2 V6s.
My expediences with North engine is that they leaked a bit of oil (from the rear crank seal) unless you use fairly thick oil. I don't remember what I used my Giulietta 2,0 and 75 TS (probably 10W-40), but in my Spider 1750 I used 20W-50 - no leaks and no oil consumption (it didn't do any winter driving). When I bought it 15W-40 in it and it leaked. Next change change it got 20W-50 and no more leaking.
