I'm getting ready to change the oil for the season, and was asking a few buddies what they use and one of them said they've been using Rotella 15W 40 diesel oil in his 340 for a few years.
says it seems to hold the viscosity better when hot and oil pressure is never below 30psi at idle.
Anyone else have thoughts on this?
