Best Motor Oil
Just wanted to get various opinions on which Motor Oil you use and think is the best. For my 2000 Jeep Grand Cherokee Laredo, Inline 6 cylinder engine with just over 100,000 miles, and with the rear wheel/part-time/full-time/4-Lo option. What would you recommend for me? I use Quaker State now just because that's what my old man always used and I've never researched any others. I tow something maybe once or twice a year, mostly in-town driving.
