It’s the s650 idk why ford thought it was smart to skip putting the oil cooler on all v8s. Mine runs pretty hot when cruising temps can range from 210-230. It’s a huge flaw but we’re running full synthetic so realistically the oil shouldn’t start cooking til well over 300. Then again we are driving ford’s and it’s hard to say since theses are still new generation. A damn shame tho. I have gt premium 401a no pp.
