I still got 1 more oil change of my Kirkland full synthetic oil left and the powerboost takes 6Q of oil. I was looking online at Sam’s and saw this pennzoil that comes in 6 quarts already so I don’t have to buy a jug of any type of oil and another quart. I only do 5K intervals and was wondering if the Sam’s oil would be worth it or what the difference is.
