Hello! I will be getting my 2019 Bullitt Mustang delivered in roughly a week and had some questions about break in and oil changes. I assume that this would apply for any 2015-2019 5.0 Coyote Mustang GT:
First, what is the recommended engine break-in procedure? On p 202 of the 2019 owners manual it says only:
“Avoid driving too fast during the first 1,000 mi (1,500 km). Vary your speed frequently and change up through the gears early. Do not labor the engine.”
The dealer I purchased the car from added that I should not drive it too hard (above say 5k rpms) and do not keep it at a particular speed for long periods of time (IE cruise control at 70mph for a 2 hour trip.) They suggested around town and spirited back roads driving for the first 500 or so miles before you start leaving it at a set speed on the highway. I checked the forums here and I have seen some folks say they limited revs to 4500 rpm during the break-in period.
Any other recommendations for breaking in this engine for maximum power and longevity? Should the engine be babied or should it be revved and pushed a bit? And is there a consensus on what rev limit to impose during break-in?
Next, regarding oil and oil changes, I plan on having my local Ford dealer perform a preventative oil and filter change at approximately 1,800 miles using the 5w20 Synthetic Blend to remove contaminants from the 1,000 mile break in period. At 5,000 miles I will have the dealer perform another oil/filter change and switch over to the Motorcraft 5w20 full synthetic. I know, this may be overkill, but I am in the habit of doing frequent oil/filter changes for SCCA, NASA road racing and track days and I assume I would not be doing the engine harm by doing this. (And no, I do not have plans to track this car.)
Finally, I also plan to do at home oil and filter changes every other oil change at 2,500 mile intervals. The manual says to use 10 quarts or 9.5 L of 5w20. My local dealer recommended putting in nine quarts without checking the dipstick and then slowly add more oil from 10th quart until dipstick is at full mark by checking the dipstick at intervals. Does this sound right?
Thanks in advance for any feedback you can provide. I really appreciate it!
