I have an 08 ST XLT with roughly 143,xxx miles on it and am running up on my 2nd oil change since aquiring the truck. Granted, opinions will vary, but what intervals do you'll change your ST's oil at? The manual says 7500 miles MAX. I currently run Mobil 1 with K&N's Gold filter and was thinking about sticking to a 5K mile interval. With the brand of oil and filter used, I think 3K miles is too extreme with the driving I do (70% fwy).
