A bit of insight needed.

Hey folks,

With the crimbo break coming up, I was going to use the time to do a few bits on my 1.6 147, including a basic oil change. I have always used Castrol Magnatec 10W40 and was planning on doing the same. When I was out at the dealers collecting a part, they recommended HPX 20W50 and suggested it would reduce the typical Alfa oil burning issue. I said why not and have a gallon of it in the boot of the car. However, after looking here, every recommendation is for 10W40. Just want to make sure I am ok and wanted to see if anyone had any experience in using it?

Appreciate all the help and Merry Christmas!

John.

I most definitely wouldn;t put that grade in a twinny at this time of year. 20 grade is very viscous when cold and you'll likely end up with cold start wear.
Take it back and get some 10/40 instead.

He doesn;t know what he's talking about - that "typical Alfa oil buring issue" is by design, not fault. The oil is used to cool the valve guides.

I'd agree with that

Not so sure about that There are as many twinnies which don't burn oil as do... In my 145 I typically got through a litre every 6K miles despite caning it everywhere...

Agree with Mave on both counts...
Gerry in TI is happy to use magnatec and my 166 was using a litre every 400 miles which someone else told me could have been causes by worn valve guides and piston rings.
Worn valve guides allowing oil in cylinder as it heats and thins (or is it loses viscosity?), same concept with rings - bear in mind I'm not an engineer...

PS ended up burning a valve and getting a top end rebuild - 1 litre per 3/4000 miles now....

As above my old 2.0 litre 147 twinny always used 10w40 and used about a litre every 1000 miles or so ... it was sold 2 years ago with 108k miles and it is still going strong so tell that wally , who probably drives a BMW, that you want 10w40

Tone honest I've never heard anyone recommend anything other than 10w40, they must be trying to get rid if that other stuff, bring it back and exchange it I'd say.

The oil use is expected to be a half liter in every 1000km. It says this in the handbook.
This is by design in the 16 valve engines, not by fault.
The oil is used to cool the valve stems.
Putting a thicker oil in to prevent it getting by the valve stems would not to be recommended by anyone who knows what they're about.

What I don't get is that this was bought in an Alfa dealer and they said they use this in all their servicing!!!

Does it say "expected to be" or "expected to be a maximum"? I expect it is the latter, which is really just Alfa trying to avoid warranty claims.

If it's a design issue, then why don't they all do it? And why do the ones which burn oil, end up burning less if they've had new piston rings?

Valve stems, or valve guides (as stated earlier)

HPX was introduced by Fiat almost 30 years ago. It was one of the first generation of synthetic oils at the time. It was recommended at the time for use in high mileage engines. At present it is recommended by Fiat for use in engines that exhibit high burn issues. Most Fiat dealers would be well aware of this, as its a common workshop solution.

in my experience every twin spark engine manual recommends 10w40 and I'm sure the 147 does too. Whatever the manufacturers manual says to use go with it, no questions asked. If you dont have the manual ask inthe 147 forum or download the manual online

10W40 just make sure it is a decent brand of oil.
