Petrol Ofisi Maximus SUPER DIESEL 20W-50, in a 17,5 kg volume, is recommended for heavy-duty vehicles, construction and agricultural machinery, as well as long-distance trucks equipped with four-stroke diesel engines with turbocharging and supercharging. This high-quality oil, based on highly refined mineral oils, provides reliable protection for commercial transport, trucks, buses, construction machines, and generators with large diesel engines. It prevents oil pressure loss and foaming in lubrication systems, facilitates cold starts, and protects the engine at high temperatures, reducing maintenance costs by extending oil change intervals.
