Doc's Diesel Oil Friction Treatment
Doc’s Diesel Oil Friction Treatment:
While engine oil does a great job protecting your engine, our innovative formula takes it a step further by enhancing wear protection and boosting lubricity, especially under tough conditions. By reducing friction and preventing corrosion, our Oil Friction Treatment extends engine life and keeps engines cleaner, making it ideal for both new and high-mileage vehicles. It effectively clears deposits, reducing stiction and improving fuel efficiency, ultimately revitalizing your engine’s performance. Suitable for use with both conventional and synthetic oils. Safe and fully compatible with all Diesel and Gasoline engine oil.
Product Details:
- Reduces engine friction, heat, and vibration
- Helps prevent injector stiction
- Adds lubrication and protection for cold starts
- Stronger oil flow in extreme temperatures
- Longer-lasting engine performance
- Outperforms conventional chlorinated paraffins in wear protection tests
- Non-chlorinated formula avoiding environmental and regulatory issues
- Non-corrosive formula eliminating the need for additional corrosion inhibitors
ASTM 3rd Party Test Results:
ASTM 3rd Party Test Results Document
| Doc's Diesel Oil Friction Treatment | |
| Wear Scar, mm | 0.552 |
| Weld Load, kg | 620 |
| Last Non-Seizure Load, kg | 200 |
| Load Wear Index | 129.8 |
Doc's Part Number:
DFOT16OZ
Directions:
- Use one 16oz bottle to treat your Powerstroke, Cummins, Duramax, and EcoDiesel Engines.
- Simply add 1.25oz per quart of motor oil. Heavy-Duty & High-Mileage engines use 2.5oz per quart of motor oil.
Change Interval:
You should add Doc’s Diesel Oil Friction Treatment with every oil change. One treatment per service keeps your oil’s protection fresh and ensures consistent friction reduction, injector cleanliness, and wear defense. For heavy-duty or high-mileage engines that run hot or tow often, you can safely add it between oil changes if performance starts to feel rough or noisy.
Above all recommendations, change according to your vehicle’s manufacturer's warranty.
- Standard Service (normal duty): Every 10,000 – 15,000 miles maximum, or as recommended by OEM
- Severe Service (heavy loads, towing, dusty or extreme conditions): Every 7,500 – 10,000 miles maximum
- Off-Road / Agricultural / Equipment: Follow manufacturer guidelines (typically 250 – 500 hours)
