DURA LUBE Engine Treatment 32 oz. Concentrated Add-In for Quieter, Cooler Engines

Dura Lube Engine Treatment is a concentrated 32 oz formula that bolsters oil performance by reducing friction and protecting internal engine parts for smoother, quieter operation.

Designed as an add-in for routine oil changes, Dura Lube Engine Treatment creates a durable lubricating barrier on vital components to help lower operating temperature, cut mechanical wear, and improve overall engine smoothness. The formula is free of solids like PTFE (Teflon®), silicone, graphite, and heavy metals, and it’s compatible with conventional, synthetic and blended motor oils for gasoline and diesel engines.

How does Dura Lube help my engine run quieter and cooler?

The treatment introduces friction-modifying molecules that cling to metal surfaces, reducing metal-to-metal contact and dissipating heat more effectively. As friction drops, so do operating temperatures and audible mechanical noise, especially noticeable in high-mileage engines.

• Forms a thin lubricating film on bearings and cam components
• Reduces friction-generated heat to help prevent overheating
• Quiets lifter and valvetrain noise for smoother idle and acceleration

Can I use this with my current oil and engine type?

Yes—Dura Lube Engine Treatment is formulated to mix safely with conventional, synthetic, and blended lubricants and is suitable for both gasoline and diesel engines. It’s intended to be added at oil change intervals and will not introduce solid particulates that could clog filters or galleries.

• Compatible with all motor oil viscosities and brands
• Safe for gas and diesel applications, including turbocharged engines
• Adds protection without altering oil change schedules

Will this help older or high-mileage engines?

High-mileage engines can benefit from the extra boundary lubrication Dura Lube provides, which helps fill microscopic surface imperfections and slows wear progression. This can translate into improved compression retention, reduced oil consumption, and a more responsive feel in worn components.

• Helps protect worn bearings, rings, and lifters from accelerated wear
• Provides added protection during cold starts when oil circulation is slower
• Can reduce oil-related noise common in aging engines

How do I apply Dura Lube Engine Treatment?

Application is straightforward: add the recommended amount to the engine oil during an oil change, then run the engine to allow the product to blend. One 32 oz bottle treats most passenger vehicle oil capacities according to label directions.

• Add during routine oil change for immediate mixing with fresh oil
• Run the engine briefly to circulate the treatment through the oiling system
• Follow the product label for dosage per oil capacity

Who is this for? Dura Lube Engine Treatment is aimed at drivers and technicians who want proactive engine protection—owners of high-mileage cars, trucks, SUVs, fleet vehicles, and anyone seeking quieter operation and potential efficiency benefits without changing oil type. It’s appropriate for vehicle owners looking to add a trusted lubricity boost to conventional or synthetic oils without solids or heavy additives.
