Hi, everyone. This is my first post since joining BITOG. I have a 2013 Ford F-150 with the 5.0 Coyote engine. I purchased it as a Certified Pre-owned with 28,000 miles on it a year ago. I now have almost 49,000 miles on it. I've been using the Motorcraft Synthetic Blend 5W-20 at each of my 5k oil changes along with the Motorcraft oil filter. I was at a muscle car shop over the weekend where my dad's 340 Demon is being restored. I've heard of the Brad Penn oils in the past (The Green Oil) and have always been intrigued, but never followed through with trying it out. The owner of the shop uses PennGrade (formerly Brad Penn) oils in all his restorations and his personal daily driver which is a modern SUV. I asked him about using the PennGrade in my F-150 and he said it would work fine with no issues. He showed me their 5W-20 Synthetic Blend, which meets Ford's spec. Any thoughts or input on this oil? If it'd be a good substitute and an acceptable choice, I'd like to give it a try. I'm due for another oil change in 1500 miles. Give the PennGrade a try or stick with the Motorcraft? Thanks for the input and allowing me to join the BITOG community! I hope to learn a lot here!
