What is Nitration?
Nitration is usually the result of an imbalance in the engine’s air to fuel ratio. When the engine runs too lean, meaning there’s too much air and not enough fuel, nitration occurs. Nitrous Oxide (NOx) becomes entrained in the oil which can form nitric acid that will eventually will lead to corrosive wear. Although nitration is more common in natural gas engines, it has become a more evident problem in diesel engines since 2002.
