Oil Change for 2005 Xc70 D5

[OWF]

Hi there,

It is time again to change the oil in my 2005 xc70 D5. Previously I have put in 5w30 as this was what the previous owner did and also what I have read around the various Volvo forums.

I have looked around online, however I can only find Triple QX to match the correct Acea A3/B3/B4 spec in the 5w30 viscosity.

I would ideally prefer to go with Shell or Castrol however I can't seem to find the correct Acea spec for 5w30. It seems only 0w30 Shell and Castrol oil has the A3/B3/B4 spec which seems odd?

Thanks in advance for any help.

Take a look on here fella, I've listed some good appropriate oils for the euro 3 D5 https://www.volvoforums.org.uk/showthread.php?t=283503

Pick of the bunch is on last page of thread.

Thanks for your help.

I have a read through your post, and have a couple of questions I hope you wouldn't mind answering.

Having used 5w30 previously would it be ok to drain that and purchase 0w30 or 5w40 for when changing? It seems there are many more alternatives for 5w40 or even 0w30 with the correct Acea spec, so maybe that would be a better solution.

I'm not sure however if this is a bad idea changing the viscosity at this age and mileage? It is coming up for 190,000 miles. Out of the two I assume 5w40 would be the better option.

Thanks again.

Theres no problem in changing viscosity.
If the engine is healthy and has a full history of frequent changes, 0w30 will be absolutely fine, you are already using a 30 oil anyway so no difference at operating temperature, and the viscosity at operating temp is much much thinner than the 0w cold. On the last page of that thread there is a table which shows the viscosities of the more appropriate oils cold/hot.
If you feel the engine is a bit tired/rattly then 5w40 will give you peace of mind. Shell helix ultra is the most ideal 5w40 for these engines due to its lighter viscosity.

Hi Andy,

The car has a complete full service history at all the correct intervals and there are no signs of rattling or tapping either, so I think 0w30 is a good option here.

Something I thought I would mention though is the oil consumption seems to have increased a little. There are no obvious leaks, so maybe its normal with the age, but would putting a 0w30 oil cause it deteriorate quicker?

I understand that when hot the 0w30 will be the same as what I have previously used (5w30) so I guess it shouldn't be an issue, but I thought I would ask.

Thanks.

As you say, they are both similar when hot, so in that respect there shouldnt be a negative difference.
However there are other things which affect consumption such as evaporation and flash point for example, so some oils decrease less/more than others. You can get a thinner oil which can have lower consumption than a thicker one.
Pick an oil, stick it in, see how you fare!
Unless you buy from abroad or drop on some little gem Ive missed, your choice is;
Fuchs Titan Supersyn Longlife 0w30 (not longlife plus)
Total Quartz 9000 energy 0w30

The total has a lower tbn so is a little less suited to a longer oil change interval, though this may have altered since the data I have as Acea have revised parameters since the current datasheet was issued, requiring B4 to have a minimum tbn of 10, the datasheet states tbn to be 8.8. Tbn is the alkalinity of the oil to combat the acids produced in combustion. However both are very good oils, so just bear in mind with your oci if you choose the Total.

Total is sold on Amazon, and the Fuchs from opieoils.co.uk or their ebay shop.

Another great oil to consider (as well as the venerable shell helix ultra 5w40) is Petronas syntium 7000 0w40 from amazon/eurocarparts/carparts4less.
