Product description

There are countless theories about which engine oil is best for a classic Volkswagen. One thing, however, is certain: older engines have different lubrication requirements from modern engines. Particularly in air-cooled Volkswagen engines with mechanical valve tappets, proper protection of the camshaft and tappets is essential.

An important role is played by ZDDP (zinc dialkyldithiophosphate). This anti-wear additive forms a protective layer on metal components under high pressure, reducing direct metal-to-metal contact and wear. The ZDDP content in many modern engine oils has been reduced to protect catalytic converters. For classic engines with mechanical tappets, a higher concentration may be desirable.

Extra zinc protection without additional additives

Lucas Hot Rod & Classic Car SAE 20W-50 is a high-quality mineral engine oil specially developed for classic cars and vintage vehicles. The oil contains an impressive 1600 ppm of zinc, together with phosphorus and molybdenum. This provides a high level of wear protection for camshafts, tappets, bearings and other engine components.

Guideline zinc levels for classic engines:

✓ New or rebuilt engine during the break-in period: approximately 2500 ppm
✓ Standard classic engine: approximately 1200 to 1600 ppm
✓ Tuned or heavily loaded engine: approximately 2000 ppm or more

These figures are indicative and depend on engine design and operating loads.

With 1600 ppm of zinc, Lucas Hot Rod & Classic Car SAE 20W-50 meets the stated guideline for standard classic engines. The oil already contains a complete package of protective additives. There is therefore no need to add a separate zinc additive.

For breaking in a new or rebuilt engine, we recommend a special Break-In/Racing engine oil, developed specifically for this critical break-in period and containing higher levels of anti-wear additives. You can find this oil under Related Products.

The SAE 20W-50 viscosity provides a strong protective oil film, even at higher operating temperatures and under heavy loads. This makes the oil particularly suitable for classic Volkswagens, campers and vehicles with more powerful engines.

Key benefits:
