[QUOTE="UnleashedBeast, post: 13345428, member: 112023"] buy all the API SN you can find on the cheap. With Ultra, either lubricant will serve you well over 32*F, which is where most Mustang owners drive their car. I'd opt for 5W-30 if you were driving in freezing temps daily, starting the car multiple times. The difference in NOACK isn't that big of a deal really. 5W-30 = 6.4% (actually tested by 3rd party @ 6.6%) 10W-30 = 4.8% Ultra 10W-30 has the lowest NOACK I have ever seen on any lubricant's spec sheet. Both formulations will have the same additive package. In my 2014 GT, I have 4 quarts of Ultra 5W-20 and 4 quarts of Ultra 10W-30 mixed. Why not, they were spare on the shelf.
