Hello everyone. I have a 2012 Nissan Versa 1.8L with 6 speed manual. I live in the mountains in the country on hilly back roads. The car is no longer under the 3 year warranty. I would like to take the car from the Nissan OCI of 3750 miles to 7500 miles or even a 1year 15K mile oil change. I live 25 miles from a larger city. My two places to get oil and filter are Walmart and Advance Autoparts. What oils and filters are designed for a 7500 mile oil change? I see the Fram TG6607 is for my car and a 7500 mile filter. The Fram XG6607 is a 15k mile filter. Which oils will offer a 7500 mile oil change under a severe driving condition? Remember I need to get my oil change from Wally's World.
