Should I still use 5W30 or upgrade to 5W40?

[tdiengine]

Hi all,

I drive an European Volvo V40 of the year 2012. I've used Shell Ultra ETC C3. Why C3? Because I've red that that the better version is for my DPF.

The thing now is, I do like reading about motoroil subjects, but don't have the experience. My Volvo diesel engine (5-cyl) is consuming about 1 litre of oil when I drive it about 6K kilometres (around 3700 miles).

So, should I keep using the 5W30 oil? Or move to 5W40 with the same C3 specs? Thank you!

Any other suggestion is welcome!

You can definitely move and try. As long as it is C3 and preferably MB229.51/52.

Thank you! Maybe a stupid question, does a W40 rate consumes a bit more fuel?

In theory. Depending on HTHS. Some 30 grades in C3 category might have qual HTHS. I highly doubt you can notice in real life.

Sounds like a good try out case for the new Valvoline restore and protect - supposed to clean rings and all and that would do more to reduce oil burning than moving up to a 40wt.

Not rated for ACEA C2/C3 AFAIK

Volvo of that vintage had low tension piston rings and would develop oil burning. OP seems to be in Europe since he mentioned Shell Ultra ECT oil, that oil is also a C2 oil at the same time. They may not have Valvoline R&P oil there but it'd be a good oil to try for a couple of OCIs to see if rings get free'd up.

If I'm not mistaken Volvo didn't require C3 oil for the engine.

Definitely a good candidate for 40 grade & stick w/ C3.

Correct, the recommended oil is Castrol Edge Professional 0W-30 A5 (full SAPS).

I switched from 5w30 to 5w40 about 2yrs ago, and I haven’t noticed any noticeable change in mileage.

Is R&P recommended for diesel? I thought I saw somewhere that it was not supported

Good point, it is not. I had to go to the website and check.

Correct - Volvo went against the conventional approach and specified ACEA A5/B5 for diesels before they launched their own specification. I think they ran large DPFs which were less sensitive to blocking.

I service a 2013 S60 for a friend, we use C3, VW 504/507 oil, all's good.
