Good Day all,
I was wondering if someone could share their thoughts and experiences. I have a 2001 Volvo S60 T5 which has a high pressure turbo motor in it. I purchased the vehicle new. Since new, (after 7500 mile break in) I have run nothing but Mobil 1 0w40 and Mann filters.
My question is this. My North American owners manual dosn't really touch on synthetic usage or viscosity. They recommend 5w30 dino up to 86 degrees and 10w30 for over 86 degrees.
My cousin has the same vehicle in OZ and they reccomend 5w40 synthetic. Anyone have any ideas what I should use.
The car runs wonderfully on 0w40. Ive got 65,000 miles on it. Knock on wood, no problems, engine is quiet, no turbo issues. Im just a little worried because many people say that a thinner oil should be used to protect the turbo bearings.
My dealer is of no help, they recommend dino oil and only offer syntec 5w50. Now Im reading 0w40 contains too many VI and may leave deposits like the 10w40 dino of yester year.
My normal maintenance schedule is drain and refill every 6mo. I normally drive 6-8000 miles in that time span. 70% hwy, I normally drive the last mile or so carefully to let the turbo cool down and to let it spool down.
I really just want to protect the bearing and engine as best as I can.
I don't want this to be a debate between Mobil1 and Amsoil. I use both oils. I use the 10w30 in my wifes Honda Accord V6 and in our S2000.
Thanks,
