been using this oil since ibought my truck new 143.000 miles ago change it faithfully every 5.000 miles and have never had a problem oil is still clear when i change it,

This is the only oil I trust to protect my engine in my Mustang GT. It took me too long to find my perfect car so I don't take any chances with any other oil.
