Mag 1 1-Gallon 15W-40 Diesel Oil. It provides high detergency and superior dispersancy to maintain engine cleanliness and suspend soot. It exhibits exceptional resistance to thermal degradation, preventing viscosity increase and deposit formation that may cause wear. The oil's superior anti-wear agents extend engine life despite high operating temperatures and extended service intervals, while its higher starting TBN provides added protection against acid build-up, preventing rust and corrosion. It delivers reliable performance over a wide temperature range, including extreme cold.
