Exactly this. When I drove trucks OTR, it was always Rotella 15w40 once a month.Companies run Delo,Shell Rotells and Mobil 1300 in their $50,000.00 engines in their semis . It would seem reasonable if the syn oils paid off the all the nations fleets would run high dollar syn of " conventional " oils.
