Yes, often there are dispersants in engine oil. Dispersants are one of many add-ons that help engine oil perform its job effectively.
As the name suggests, the dispersant’s job is to keep the soot particles within your engine well dispersed. By keeping contaminants apart, there is less chance of contaminant build-up and a lower risk of engine damage.
Dispersant is in the engine oil and does its job while the oil flows through the working engine. In conjunction with detergent to neutralize acid compounds and suspend contaminant particles, these additives keep your engine clean.
Just like an oil change is a necessary part of car ownership, having a frequent car insurance switch can help you keep your prices low and your wallet happy. Use super app and insurance broker Jerry to find great coverage at a low price.
