I changed my oil every 5K in a Honda 3.5L and used Mobile 1. Probably why it ran like a top when I traded it after 17 years and 230k miles. What RPM does that truck run at 60 mph??

Ok, but how many gallons of motor oil in the 2 engines? You take the 636 gallons of diesel consumed and divide that by the oil in the 2 engines. Think you will find you're around 100 gallons of fuel consumed for each gallon of oil in both engines.

Another good oil report!

At some point you might consider doing the transmissions. It will give you an idea of how the clutch plates and bearings are holding up. Also, if you see sodium (salt) starting to elevate, it's an early warning of the transmission cooler starting to leak raw water into the transmission oil.

Good advice, I will do that this fall. All new coolers last year.
