as regulars will know i am batteling truely awfull oil consumption figures (up to 1tr per 100 miles)..and having spent in excess of $1000 trying to solve this I now wonder if its the fact that I have been buying oil that is too modern for this engine...

basically i use oil on long fast motorway runs and have filled with mobil 0w40 as this should (my thinking) be nice and runny to get to that turbo faster...however I now note that Volvo recommend 10w40, and indeed for runs such as these recomend 15w40 or 20w40...

Anyways being unable to get mobil 1 10w40..yeh i know i should be able to get it but no one stocks it....I am going to try good old fashioned part synthetic 10w40...but has anyone else tried 0w40...and had issues or can i rule this out...?

I must say this is pretty much the last throw of the dice for volvo ownership for me...I have been so disapointed in the car....it drive great, lovely to sit in but so unreliable....and requiring so much work (which lets face it a 135k miles car just shouldnt...)

well just wondered if i might be onto something..at least if someone could confirm or deny the suspicion...
