can i ask why u guys r running thicker oils in your svts when 5-30 is the ford recommended oil. i run amsoil 0-30 so it flows quicker in winter. but i run yearround. i would not feel good running 15-50. have u had any problems? the thinner oil might find cracks to leak thru that the thicker oil might not have gotten thru. any signs of that yet?
