Engine oil additives good for engine
by Alex
Expert answer:
Quick answer
They can be good for an engine if they resolve mild leaks, reduce friction, or help with sludge. Yet for a healthy motor or one with severe damage, the additive might offer limited benefit.
Detailed answer
When an engine has minor wear—like aging seals, sticky lifters, or deposit buildup—an appropriate additive can indeed support smoother operation. Friction reducers diminish metal-on-metal contact, while seal conditioners reduce drips. But if everything’s already in top shape, adding more chemicals could be redundant. In worst cases, unneeded or mismatched formulas might create sludge or thickening. “Good for the engine” truly depends on the engine’s current state and the additive’s exact role. Used strategically, though, they can maintain or improve performance.
