Here's a look at changes that have happened for Shell Rotella Diesel oils: CK-4 & FA-4 OilsBut it is still JASO certified.
Someone wrote in an earlier thread that he was surprised how much oil was trapped in the engine by webbing (cast in reinforcement). Oil was also to be found in the clutch. This means running the engine with the starter to squeeze out the last little bit of oil will do nothing to move oil trapped by the internal structure of the engine. It's not only a bad idea to spin the engine w/o oil, but doing so will not move any more of the old oil.Ok, I read one article that says to pull the plug wires and run the starter motor for 2 seconds to push out the last of the oil. . .sounds scary. . . .
