Finding the best engine oil for the OBS 7.3 Powerstoke is a process that takes time.  Sending oil analysis off after each change and then you must decipher the results and it takes time.  We've test oils and came to the conclusion that a good semi-synthetic or full synthetic gives the best results for a longer engine life. A new OEM oil filter and regular additives keep you engine clean and lubricated running for many years.
