Oil & Fuel Tractor dyno break-in.

I've noticed that some threads mention that the tractor engine oil gets black quickly. When I bought my new T2310, the dealer was quite insistent that I should allow them to dyno break-in the engine for 5 hours before the tractor was delivered. I ultimately could have refused but I allowed them to do so. He said that it was essential to seat the piston rings, immediately, to ensure that the tractor would perform correctly. He also told me to put the engine under heavy load in the last 10 hours before the 50 hour change.

By the time of the 50 hour oil change, the oil had turned to a medium dark grey (nowhere near black) and never thickened. I changed the oil at 50 hours. Now, at 72 hours, the oil is clear with a very, very light grey tint. The engine is very smooth and powerful running. I think that the dealer was right on the money in recommending the dyno break-in. Does anyone else have a similar experience with their tractor/ dealer?

NH requires all tractors with a pto to be run on a dyno during the pre delivery inspection. This is to ensure 1) the engine develops full power 2) makes sure nothing leaks, and 3) helps with the break-in. Diesel engine oil turns black due to soot getting past the rings. Running the engine on a dyno helps seat the rings so they seal better. Also, the new tier 3 engines will not blacken the oil as fast because they burn so much cleaner than the prior engines.

Dyno break-in is suppose to be the best way to start the life of a new tractor. Most dealers don't do it. When I bought my Case-IH 125 maxxum, they did it without asking. I just happened to stop buy the dealer to see it and it was running on the dyno.

Don't worry about the color of the oil. Even the oil you just changed will become "dirty" looking. It is normal for diesel engines. The newer tier engines run cleaner but will still blacken the oil.
