and notice the -76 degree pout point. Wow, great for Wisconsin winters and a tough high temp oil too.
I should have added that the manual recommends 0w30 and 0w40 from 'off the scale below 0' to 104F, 5W-40 from -10F to 104F, and 10w30 from -4F to 104F. In the last Volvo, I thought the car was just slightly harder to start w/ Red Line 10w30 in really cold weather... I would love something I could run year round, maybe even buy by the case.
This car is just different enough from the previous Volvo where I started wondering what I need to tweak.
