id do 5w20 going into the winter, and probably all year around unless i lived in las vegas or somewhere ridiculously hot or wanted to track my car on a road course
EDIT
found this on another forum so mabe im mistaken :
I love that dealer mechanics are now the subject matter experts on this and not the engineering team who designed and built the thing......
Anyway stop spreading mis-information. You should NOT change the oil viscosity from what your car was factory equip'ed with.
The engine calibration is viscosity specific and there are implications to changing it.
The Boss 302 calibration for TiVCT had to be tweaked to accommodate the 5w-50 oil.
You should not deviate from factory oil viscosity specifications period

I wasn't joking. Lots of gt500's running that weight. 5w50 is probably only necessary for the track. 5w40 is going to shear down to a 30 weight pretty quickly unless you run one of the fancy oils. I think 5w30 is minimum for these cars, unless you drive like my mother.

Has anyone contacted a reputable Ford Mechanic or Engineer on this topic? I would like to know what oil came in my 2013 GT with Track Package from the factory.
It seems like there are many opinions on this thread but I would just like to know what oil came in the car out of the factory.
As everyone else has stated my manual says 5w-20 and the cap says 5w-50.

The owners manual is the same for all gt. There was a notice in the manual from ford included for the track pack cars.
