Can you mix oil additives

Alex by Alex

Expert answer:

0

Quick answer

Mixing oil additives from different brands or types can lead to chemical conflicts, foaming, or sludge buildup. It’s best to use a single, well-formulated additive for your specific need.

Detailed answer

Each oil additive formula is balanced with specific detergents, friction reducers, or seal conditioners. Combining different brands may result in excess of certain ingredients, which can negatively impact lubrication and engine function. Some mixtures can create residue, clog oil filters, or alter viscosity in unintended ways. Instead of mixing, choose a comprehensive additive that addresses multiple concerns or add separate treatments at different intervals.
