Below is part of an email thread from a gentleman selling a complete, tired LB7 Duramax for rebuild purposes on Ebay. Here is part of the information he passed along to me. I wonder how many more miles he may have gotten if he had used synthetics from day #1, rather than Rotella. Who knows...:

"""my truck had 328,000 on it when the motor was replaced. I lost oil pressure it went below 20 lbs and when I saw that I parked the truck as soon as safe to do so. The shop came out did a check on it and towed it to their shop The Truck Doctor in Science Hill KY. The engine had not been overheated as I make my living with this truck and keep up with my maintenance."""

""" I change my oil and filter every 3000 using rotella or every 7000 when I switched to Amsoil. I also switched to Amsoil in my transmission and differentials transfer case. I change all filters frequently less than what is called for. I run K&N Air Filter as well. My motor had 328,000 when replaced. I have had the trans flushed more than once along with differentials and transfer case. I do alot of maintenance to keep my truck on the road. """

I wonder if he fuel in oil? This is the most often reported cause of a loss in oil pressure in the LB7.

I'm curious to know why the engine was replaced. Low oil pressure isn't necessarily reason for replacement. The engine has an oil pressure regulator, as well as dozens of places a leak could occur, dropping the pressure. Anyway, 328K isn't too bad.
