Hello all,
I am switching to Royal Purple and am wondering if I should stay with the Ford recommended 5W-20 or go to 10W-30 or possibly something else. Just want to get some recommendations on full synthetic oils.
Thanks

I have tried to search the forums for anything regarding swapping the 3.73 gears with 3.55 gears on the gt performance package.
3.55 should make 1st more usable when DD, help on mpg a bit and allow for finishing 1/4 miles in 4th instead of needing to shift to 5th.
3.73 may be better for...
