Spoke with Ford today on oil consumption of these motors. Unlike my GT500 or the boss or any other car I have owned , we all know this engine was designed differently for high reving.
Combination of the crank and the way the rings on the piston designed.
My oil consumption on my 2017 GT350 is about a quart every 1200-1500 miles. According to Ford this is within specs of the motor. The supplement addresses this problem.
They strongly recommend checking the oil every 1000-1500 miles and that higher reving and or spirited driving can increase oil consumption.
I asked if you drive the car docile if that would decrease oil consumption and he couldnt say.
Just a FYI to everyone.
