Would Recommend[This review was collected as part of a promotion.] No competition, hands down. If you want the best QUAKER STATE first place. Performance in a bottle, got to love it. Twenty plus years never disappointed. It's just that sound when pouring it in the motor and it idles so smooth. Or maybe when you check the dipstick randomly for months and it's still level and clean. Makes a beater run like luxury. We need a national QS Challenge it's almost tax time. Every purchase of a vehicle gets QS Challenge...
