I use Shell Rotella T 15w-40 in the engine. Power steering, transmission, and transfer case all get dextron 3, usually house brand of wherever I'm shopping. Valvoline 80w-90 in the diffs and hubs.

I use Shell Rotella 15W-40 for the engine oil and then what ever dextron 3 Walmart has on sale for the transmission.

I'm interested in hearing about this too. I know what we used in the military and am curious about personal preferences, synthetics etc.

All modern diesel eng's use 15w-40
