Suitability for Classic Road and Competition Cars:

• The Driven HR range is recommended for use in classic road and competition cars.

ZDDP Levels for Flat-Tappet Engines:

• The oils in this range have sufficient levels of ZDDP (zinc dialkyldithiophosphate) to protect flat-tappet engines, even with increased spring pressures up to 30% higher than stock.

Always follow the manufacturer's recommendations and guidelines for your specific engine and usage conditions to ensure the best performance and longevity.

Detergent Levels and Mileage Endurance:

• The detergent levels in HR oils are designed to handle up to 8,000 road miles.

Anti-Corrosion Pack:

• The oils feature a unique anti-corrosion pack to protect engines that see little use, preventing the damaging effects of dry starts.

Ethanol-Neutralizing Additive:

• An ethanol-neutralizing additive is included to combat internal rust corrosion.

Available Grades:

• The HR oils are available in 10W-30, 10W-40, and 15W-50 grades, in both mineral and synthetic formulations.

Oil Change Recommendations:

• It's recommended to change the oil after racing or track days if it turns black, indicating potential fuel interaction with the oil.

Warm-Up Before Drain:

• It's advised to warm up the engine before draining the oil to ensure optimal draining and effectiveness.

Monitoring Oil Pressures:

• Racing conditions can stress oils, and while the HR oils are temperature-stable, continuous racing may lead to thinning. Monitoring oil pressures is important, and for ultimate racing applications, the Driven XP range is recommended.

Excellent Storage Oils:

• The HR range is suitable for storage, containing additives that protect against rust and corrosion caused by moisture and ethanol from the fuel.
