FAQ

What is a friction modifier?
A friction modifier is a chemical additive blended into oils or fluids to decrease friction between metal surfaces, reducing wear and improving the smoothness of gear and clutch engagement.

When should I use a friction modifier?
Use friction modifiers in limited-slip differentials (to eliminate clutch chatter), select automatic/manual transmissions, certain engine oils, or wherever your manufacturer specifies. Always consult your owner’s manual or vehicle service guide.

Can friction modifiers improve fuel economy?
Yes, by reducing internal friction, these additives can help improve fuel efficiency—particularly in differentials, transmissions, and high-mileage or performance engines.

Are friction modifiers safe for all vehicles?
Most are formulated to be compatible with modern and classic vehicles, but always check your vehicle’s requirements and the product label before adding them to your fluids.

Can I use friction modifiers with synthetic and conventional oils?
Absolutely! Most friction modifiers are designed to work in both synthetic and conventional lubricants—just be sure to use the recommended amount.

Will a friction modifier eliminate limited-slip differential noise?
Yes, these additives are commonly used to quiet clutch chatter and noise in limited-slip differentials by allowing the clutches to slip as intended.

How do I add a friction modifier to my system?
Pour the additive directly into the relevant fluid reservoir (engine, transmission, or differential) as instructed, typically during a fluid change or service interval.

What if my product arrives leaking or damaged?
Customer satisfaction is our priority. If your friction modifier arrives leaking or damaged, contact us within 7 days for a quick replacement, exchange, or refund.
