Hey whats up.. quick question.. i just picked up a 2000 s70 2.4liter base model. for about 800 bucks.... runs very well for its age can't beat the price... the guy that had it said he put in castrol 20w/50... it dose have exactly 200.000 miles on it...should i keep using that oil or should i use something like 10w/30 any recommendations would be great

 

Man, get that oil out of that car today. Depending on your climate 10W-40 is the thickest you should run daily.

Check out the new Volvo owner area and look at the owners manual. That should be your first stop for answering questions.
