I have a GMC with 220,000. I have been using Super Tech Synthetic and ST Filter and love it. However, I may be getting a newer Ford F150 soon which takes 5w20. Super Tech doesn't have a synthetic 5w20. So I am doing some oil research. Would you recommend Ford Motorcraft synthetic blend with Motorcraft filter or NAPA full synthetic with NAPA Filter? I know they are both good oils and filters, I would just like to make the best choice. The motorcraft is a bit cheaper and is Ford endorsed but I kind of want a full synthetic. So, I am kind of torn.
