Thanks, Jason! I am going to take your advice and change the plugs. I’m sure there’s a good thread here regarding the best ones to use. Do you have a recommendation?The extended warranty should provide substantial piece of mind. Castrol Magnetec gets good UOAs in the Ecoboost. Premium gas is not required, but will reduce fuel dilution. The plugs are probably toast at 100K, so you it may be prudent to replace them proactively, especially if you can do the work yourself. Watch for throttle body failure as well. It's a relatively inexpensive fix, but the failure mode can be frustrating. Enjoy the new vehicle and safe travels!
IRT throttle body failure. How do you ‘watch out’ for that?
