So a buddy of mine from Montana is a groomsman in my wedding this June. He has to drive from MT to Iowa which will total about 1800 miles one-way and will quickly add to his already accumulated 93,000 mile total. I told him I would change the oil in his Saab for him since that is a lot of driving to do. I had planned on using a Napa Gold or PureOne for the filter. I'm just going back and forth on the oil to use. I have 5w30 Pennzoil Platinum and Mobil 1 in my storage closet at home. Both meet some of the toughest turbo specs. Which would you all choose? I was leaning to the Mobil 1 since it has a slightly higher HT/HS viscosity. What do you all think? Also, I've been looking for some listing on the sump capacity, but I can't find it. My guess is that 5 qts would fill it, but I wanted to be sure. Thanks in advance!
