Re: oil for s70 t5 (csc23)

What year? And what are you running right now? 5W-30?<p>I think the manual states that 10W-30 is what to use, not sure. But yea, if you live and drive where it gets pretty hot constantly, definitely not a bad idea to go with the slightly heavier weight.<p>

10w-30 Mobil 1 synthetic is what I use when I'm in NY for the spring through fall. Back when the car was driven in Maine winters I used a 5w-30. <p>Here in southern Sweden the dealers use 5w-40 and I follow suit with a synthetic one...in northern Sweden I think people run a 0w-30 in the colder months.

Re: (JRL)

I use the same oil year around. The upper number is the operative one when the oil is hot. I like the 5W-40 number spread (Amsoil in this case), but I've used M1 5W-30 too. Nothing wrong with that.<br>The lower number kinda goes with what your personal philosophy about oil is.<br>Believing oils are much better than they were even 10 years ago, I think a lower low-number flows faster and better on a cold start. You may believe a higher low-number coats parts better for cold-start protection.<br>I don't think you can go wrong either way, as long as you use a synthetic.

Mobil 1 10-30 every 5 k miles in summer- I may go to 5-30 for winter months.<br>
