Or ask me-my xB sheared 0W30 AFE well down into a 20 weight in only 7,000 miles, but the 5W30 EP stayed in grade easily at 10K, & could have gone further. The UOAs are on here. If they do it again, Pep Boys will have M1 quarts for $5 on Black Friday, & I've gotten WM to price match EP for that price. Or get it when there's a $12/5 quart jug rebate.
