The Driven Racing Oil HR5 Mineral 10W-40 High Zinc Engine Oil is designed for owners of muscle cars, hot rods, and vintage sports cars seeking robust engine protection. Its key benefit is the high zinc content, providing superior anti-wear protection for older flat-tappet and push-rod engines, alongside advanced rust and corrosion inhibitors. A potential consideration is its petroleum-based formulation, which may require careful assessment for compatibility with modern sealing materials not originally designed for such additives, though it is stated as safe for O2 sensors and catalytic converters.

The high zinc (ZDDP) content provides enhanced anti-wear protection, which is critical for older engines equipped with flat-tappet and push-rod valvetrains that are prone to wear.
While safe for O2 sensors and catalytic converters, this oil is specifically formulated for classic and vintage applications. Modern vehicles often have different lubrication requirements and may be sensitive to high ZDDP levels. It's best to use oils recommended by the vehicle manufacturer for modern cars.
The HR5 formula includes specialized additives designed to create a protective barrier on internal engine components, shielding them from moisture and environmental contaminants, thereby preventing rust and corrosion, especially during periods of inactivity.
While the oil is safe, engines with roller camshafts typically do not require the high levels of zinc found in this formulation. Using this oil in such an engine is generally not necessary and may not offer additional benefits over a standard modern oil.
Follow your vehicle's specific owner's manual recommendations. For regularly driven classic vehicles, a general guideline is every 3,000 miles or annually, whichever comes first.
No, the Driven Racing Oil HR5 is a mineral (petroleum-based) engine oil.
Verify the correct oil viscosity (10W-40) is used and that the oil filter is properly seated and filled. Ensure the oil level is correct on the dipstick. Check for any external oil leaks around the drain plug or filter.
This oil is designed for wear protection. Persistent noise might indicate existing internal wear or other mechanical issues unrelated to the oil. Consult a mechanic for diagnosis.
Dark oil typically indicates the detergents are working to clean the engine. Foamy oil can indicate air being introduced into the oil system or excessive heat. Check for proper ventilation and ensure the oil is not overheating.
Setup: Ensure your engine is completely cool before draining old oil. Remove the oil drain plug and allow all old oil to drain. Replace the drain plug, ensuring the gasket is in good condition. Remove the old oil filter and screw on the new one, pre-filling it with a small amount of Driven Racing Oil HR5 10W-40. Fill the engine with the recommended amount of HR5 oil according to your vehicle's owner's manual. Always check the oil level using the dipstick after running the engine for a few minutes.
Compatibility: This oil is specifically recommended for muscle cars, hot rods, and vintage sports cars. It is particularly beneficial for engines featuring flat-tappet camshafts and push-rod designs. While safe for O2 sensors and catalytic converters, owners of vehicles with modern, sensitive seals or those designed for full synthetic oils should consult their vehicle's service manual or a qualified mechanic before use.
Care: Change the oil and filter at intervals recommended by your vehicle manufacturer or every 3,000 miles, whichever comes first, particularly for vehicles driven regularly. For vehicles stored for extended periods, consider changing the oil before storage to ensure optimal protection against rust and corrosion.
