but all in all, the warranty is FREE as long as you sign up before 75k on your vehicle, parts are professionally installed, and you get your oil changed every 4k. the store logs it for you, but if you decide to change your own oil, you can go online, type in the oils upc code, and it verifys that you bought the oil, and loggs a change for you, and you have three strikes, say you miss a change, or go somewhere else for once. guarantee still valid!
300,000 miles, any oil related failure gets you a BRAND NEW( not used) motor, rental car, and installation costs oin valvoline
