Driven Racing Oil DT40 Fully Synthetic 5W40 Engine Oil - 1 Quart

DT40 is specifically designed for high-revving and high-output naturally aspirated and turbocharged engines, commonly found in modern sports cars and performance vehicles that operate under extreme conditions.

The high Zinc content provides excellent wear protection but may not be compatible with all catalytic converter systems over the long term. Always consult your vehicle's owner's manual or a qualified mechanic to ensure compatibility.

While DT40 offers benefits like fuel economy, it is primarily formulated for high-performance applications. For standard daily driving in less demanding vehicles, a different oil meeting specific OEM requirements might be more appropriate and cost-effective.

DT40 utilizes an advanced synthetic formula that minimizes oil foaming and vaporization, which are common causes of oil loss in high-performance engines operating at high temperatures and speeds.

This oil is a 5W40 viscosity grade, meaning it flows like a 5-weight oil at cold temperatures and maintains a 40-weight viscosity at operating temperatures.

The advanced synthetic base oils in DT40 provide superior film strength, better thermal stability, and enhanced protection against viscosity breakdown under high shear and high-temperature conditions compared to conventional oils.

Your vehicle's owner's manual will specify the exact engine oil capacity required for an oil change.

Verify the oil viscosity is correct for your engine and ambient temperature. Ensure the oil filter is correctly installed and not blocked. Check for any oil leaks in the system.

Foamy oil can indicate excessive air entrainment; ensure the oil level is correct and check for proper crankcase ventilation. Milky oil suggests coolant contamination, which requires immediate attention to identify and repair the leak.

While DT40 is designed to reduce oil consumption, persistent high consumption could indicate worn piston rings, valve seals, or turbocharger issues. Ensure the oil level is maintained correctly.

The high ZDDP (Zinc Dialkyldithiophosphate) content in this oil might affect long-term performance or trigger warnings in vehicles with sensitive catalytic converters. Consult your vehicle's manual or a specialist if you suspect incompatibility.
