The Additive Chemicals in Engine Oil



So, what are the usual additive chemicals are added into the engine oil? The most common additives are:

1.      Detergent-Dispersant Additive
a.       Detergent-Dispersant additive are added to engine oil to prevent and to clean carbon deposit that formed inside engine parts. But, overtime, heat and thermal cycling depletes the detergents. Then, the carbon deposits will begin to coat the inside of the engine, plug oil passages and cause catastrophic engine damage. Therefore, the detergent-dispersant additive in the engine oil is not enough to clean the carbon deposits inside the engine. You need to add extra additives to really get your engine clean and maximize its performance. That is why Liqui Moly has the extra additives like ENGINE FLUSH PRO, which has been proven to clean the engine thoroughly from carbon deposits, thus maximizing engine performance and prolonging engine life.

2.      Acid Neutralizer
a.       As the engine operates, acid will build up in the oil. Acid build up will cause bearing surfaces to deteriorate. All modern motor oil contains sodium hydroxides (NaOH) to combat the acid build up in the oil.


Besides the common additives that are added into engine oils, there is also a special additive that can be added to engine oils. This special additive is usually found in higher-quality engine oil. The special additive is:


1.      Mos2 (Molybdenum Disulfide)
a.       Liqui Moly products contain this special chemical called MoS2 to enhance its lubricating properties. MoS2 in motor oil has been proven to enhance the lubrication quality of oil, to allow longer interval between oil change, and to allow the oil to perform better in harsh conditions.


So, there you go guys, the additives of engine oil. It is important to choose the right engine oil for your car. Also, remember that high-quality engine oil will save you more money in the long run.

Have a nice day and always remember to drive safely!

  1. Hi
    My engine made a lot of metal 145hrs after a factory overhaul. The model has known poor delivery to the top-end. The engineer found that the top-end was scored and damaged consistent with poor oil delivery to the top-end. The factory engineer agreed to repair the engine. An oil report showed high potassium consistent with damage to the engine alloys. However, the factory business manager claims potassium suggests that an oil additive was used contrary to their maintenance guide and refuses to repair the engine.
    No additive was ever used in this engine however this must be proven.
    As such, I am asking every manufacturer of engine oil additives if potassium is ever a component of additives.
    Your assistance would be greatly appreciated.
    Kind regards
