I had a rescued 79 300TD. It sat under a pile of leaves in the neighbor's yard until I bought it. I pumped out the almost-black diesel fuel, changed fluids, replaced injectors (bad nailing), and replaced tie rods and the damper (plus wind screen, tires, and many other things). Still it drove

Ralph, What you're describing sounds like a partial Italian tune up. The greatest carbon removal will occur when you fully load the engine at high RPM, and keep it there. Climbing a long steep hill at 80% or greater throttle, resulting in the temperature gauge climbing and staying elevated

Indeed - you will learn if there is abnormal wear in the engine, and get a feel for how much you could extend the change interval. My analysis results are coming back well within normal limits with M1 running at least 12,000 miles on all the engines. Granted, I'm not running an OM61x engine

Unless you are looking to extend the drains, it probably wouldn't be much help in a 240D. I see more benefit with some of the later models where head gasket failure or cracked heads are somewhat common. The oil analysis can help you determine if coolant is making it into the oil and if it is,
