Learn how oil additives can help prevent sludge…
Do oil additives really work
by Alex
Expert answer:
Quick answer
Yes, oil additives work when used for the right purpose. They help with friction reduction, sludge prevention, or sealing minor leaks, but they can’t fix mechanical failures.
Detailed answer
The effectiveness of oil additives depends on their use case. Friction reducers help in high-stress conditions, detergents remove sludge, and seal conditioners improve aging gaskets. However, expecting an additive to repair significant mechanical damage is unrealistic. When chosen for a specific purpose and applied correctly, they provide real benefits, but they aren’t a replacement for proper maintenance and repairs.
