I have a 2009 ford f-150 with a 4.6l auto transmission, regular cab, 4x2. I plan on keeping this vehicle for a long time. It will be used for going to work and some light towing and hauling on occasion. I bought it used and it had 2670 miles on it. Currently has 4360. I average around 12,000 miles a year and 70%-80% are highway. I use pennzoil platinum in our caravan with really good results and i'm leaning towards that. Just thought i would get some advice and see what you guys think.
