Did you know that Zinc Dialkyldithiophosphate (ZDDP) is vital for wear protection in classic engines? ZDDP has been a cornerstone in lubricants since the 1940s, forming a protective tribofilm on metal surfaces that significantly reduces friction and wear, extending engine lifespan. This is especially crucial for vintage engines with flat tappet camshafts, which experience higher wear due to metal-on-metal contact.
Modern engine oils now contain lower ZDDP levels to comply with emissions standards. However, classic car owners and enthusiasts often require higher ZDDP levels to maintain optimal wear protection for these engines. Specialised high-ZDDP oils or additives are therefore recommended for older engines, as they retain the necessary protective properties without the risk of catalytic converter damage associated with newer formulations.
At Valorem Chemicals, we understand the unique requirements of vintage engines. Our high-quality ZDDP additives are designed to keep your classic engines running smoothly and reliably.
