Just recieved a coupon in my email from nissan for a $10 prescheduled oil change , only honored on Wed and Thursdays. So I made appointment for Thursday, had coupon and they took my car. John from service never asked me if I wanted synthetic oil, he just charged me 20$ at the end, saying my car had to have synthetic oil. Umm no, I've owned lots of nissan and this isn't a high performance car and I know how to read my manual, it can take regular conventional oil. Thank you for thinking you pulled a fast one on me, but nope I kept my composure, smiled, left and called corporate. So shady. Honor the coupons and ask before you decide to upgrade, I came in only for the $10 oil change and now I'm never coming back. I know your location needs your numbers up, so a $10 oil change isn't something your into, but john, it's not your company. Please hire some ethical managers nissan.
