Tractors equipped with SCR systems can expect to be operated as much as two times longer between oil changes due to the lessened carbon and soot contaminants that the lubrication system has to filter out. The new Mahindra Common Rail Diesel (mCRD) engines are only equipped with a DOC component. It so happens that when they tune for low soot, it also favors fuel consumption, so that is normally what is done. How To Maintain A Compact Utility Tractor, Snow Removal: What Implement to Best Handle Winter. Urea and consequently DEF is not overly toxic to humans. 677.

The Mahindra mCRD engine is an eco-friendly and fuel-efficient high-performance engine that lowers greenhouse gas emissions by over 360 tons per year. This can be done by a qualified mechanic or welding shop. The way they do that is to deny the engine some oxygen, which is why they re-circulate the exhaust, since it is some O2 with mostly CO2.
