first of all, been a fan of this forum for many years and have learned tons so thank you all for that. I have a 2020 f150 with the 3.0l diesel, on the Facebook pages people commonly run 5w-40 t6, however I found on here people seem to report the Mobil 1 turbo diesel truck is a better shelf oil. I will continue to run a 5w-40 oil, I live in central Texas, motorcraft filter and 5k interval. Thoughts on mobile 1 TBT oil? Oil price, to me, is irrelevant as I’d rather waste a couple bucks on better oil and short intervals than have engine issues in the future so any recommendations on oils is greatly appreciated.
