you ain't lieing!
I have two customers at work that own the same truck/engine... drive in the same environments, use the same OCI... one uses Rotella 15w-40 dino, the other uses plain jane M1 10w-30........ I know people don't like to compare colors of oils.... but I know what color that rotella was when I put it in there, and I know what color it is 15 seconds after the engine is running.... BLACK as night! Yet this guy who runs M1 10w-30, not even a diesel oil.... has the cleanest engine and oil I've ever seen in a diesel.......
the M1 engine has more miles on it as well............ and hes not even spot on with the OCI(the oil can probably afford to go longer anyhow)
but the guy who uses Rotella religiously changes his oil every 5k or less....
