I run valvoline in my Titan and SUV. I have used it for the last 15 years and seems to be good. I had a nissan hardbody that I used Valvoline in for the 10 years I owned the vehicle. Had over 100,000 miles on it before I sold it and didn't use any oil. I changed it every 3,000 miles, except once. I got some good advice on this forum about having your oil tested by
www.blackstone.com. I am going to have mine tested when it has over 7,000 miles to see how the numbers look on the valvoline oil. Seems like Chevron has been mentioned on this forum alot. There is one guy on this forum who seems to know alot about oil. You may want to do a search and read thoses threads. This forum is great.
