New member here and looking for suggestions. I have a 97 F-150 5.4 ohc v-8. It has 95,000 miles and I have been using Motorcraft Oil and filters or sometimes supertech filters. Really do not want to start the synthetic on it this late although Mobil 1 goes in my wife's Explorer. I drive approximately 30 miles each way to work and currently change oil on 3,000 miles. Any suggestions for changing brands of oils or is the Motorcraft okay?? I do have a slight piston slap issue in cold weather which does sort of go with the territory on the older 5.4 Triton engine. You guys seem to know what you are talking about and I just wondered what your opinions are. Really am looking to stay with an otc dino oil though.
