Quick answer
Oil additives aren’t strictly necessary for many well-maintained engines, as modern oils have robust built-in chemistry. However, targeted products can help address mild leaks, noise, or wear issues.
Detailed answer
Not every engine needs an additional oil additive. Modern motor oils arrive with sophisticated additive packages—detergents, anti-wear agents, friction modifiers—that handle typical driving conditions. If your vehicle runs smoothly with no leaks, noises, or signs of sludge, you likely don’t need a separate product. On the other hand, older engines or those with minor hiccups—like a slight valve tick or small seep—can sometimes benefit from specialized formulas. These might reduce friction or recondition seals, potentially prolonging engine life. It’s about problem-solving, not mandatory usage. If there’s no symptom, you might save money by skipping the extra chemicals.
