I have been using it for years and I love it. My Tundra gets 0w-20 and is good for 25,000 miles or one year which ever comes first. I usually change it once a year whether it needs it or not. It cost more but in the long run its much cheaper. My last Tundra used it since new and has well over 200,000 miles on it. I also run it in all my bikes from motocross to street plus anything else that needs oil.
