The ideal operating range for Mustang engine oil is 180°F through 200°F. While operating within this range, your Mustang's engine oil works as a lubricant, coolant, and cleansing agent in your Mustang's 4.6L, 5.0L, or 5.4L engine. Oil that exceeds 220°F rapidly loses its ability to lubricate and cool causing accelerated fatigue and premature component failure. These Mustang engine oil coolers from Ford Racing and Canton will help to keep oil temps low and components working properly. With some Mustang Engines or Suspensions, you need to relocate your Oil Filter. If you need to relocate your Oil Filter, it's a good idea to go ahead & add an Engine Oil Cooler while you're there!
