Best oil grade for an older modern car
Hi,
I have my camo Volvo petrol 2.0 turbo and the manual states 5W/30 oil but the car has done almost 100k probably hard miles and I’m now thinking this
watery oil is fine when new but really a bit thin for the car now, apart from going to a 5W/40 oil is there a better grade or solution for high
mileage cars. I recently changed the oil with 5W/30 but the engine now seems nosier especially tappet noise which is now noticeable.

Stick with 5w/30 full syth unless it galloping through oil.

doesn't burn any oil and the emissions are clean for the MOT, just after changing the plugs and they were spotless so generally I think the
engine is in good health, just the last oil change seemed a little bit nosier...

I'd stick with the OEM oil recommendation. 100k is not that higher mileage and as above unless it's using a lot of oil the OEM spec
should be best.

Well just and update on this...
I had 5w/30 fully synthetic in but decided this was not acceptable as the noise from what seems to be the cam gear is far to loud, especially as I
have another recently purchased identical S60 which doesn't make any noise (not sure what grade its on).
So still going on the hand book for the time of year changed to a 20w/40 part synthetic and all the noise has vanished! it now runs a silently as it
should.
From this even though both oils are fully to the manufactures spec the protection of such thin oils I'd have to say is questionable and will be
steering clear of these grades from now on.

I live in the tropics, but have tried to keep using recommended oil.
Notwithstanding, last two oil changes I haven´t found 5W30 and used 10W40 if my memory serves me OK.
I may as well stick to the new spec as easier to find and additional peace of mind as we don´t have such low temperatures in the morning, therefore
such low viscosity is not needed at startup.
You may need to go back to 5W30 in winter.
Hope my post makes sense.
Beware of what you wish.. for it may come true....

Personally I wouldn't have gone for a part synthetic oil of any grade in a turbo car, but I only have internet based gossip to back that up.

Ditto - I even use fully synthetic in my van
Cheers!
