Product description

A new or rebuilt Volkswagen engine places particularly high demands on lubrication during its first hours of operation. The camshaft and mechanical tappets, in particular, need reliable protection against wear during this critical break-in period. The same applies to heavily tuned engines, where higher engine speeds, stronger valve springs and increased power output result in greater mechanical loads.

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.

Extra zinc protection for break-in and racing

Lucas Racing Only SAE 20W-50 is a special mineral engine oil with an exceptionally high zinc content of approximately 3000 ppm, together with phosphorus and molybdenum. This provides additional wear protection for heavily loaded components such as camshafts, mechanical tappets and bearings.

Guideline zinc levels for classic engines:

✓ Standard classic engine during normal use: approximately 1200 to 1600 ppm
✓ New or rebuilt engine during the break-in period: approximately 2500 to 3000 ppm
✓ Heavily tuned or racing engine: approximately 2000 to 3000 ppm or more, depending on engine design

These figures are indicative and depend on engine design, operating loads and the overall oil formulation.

With approximately 3000 ppm zinc, Lucas Racing Only SAE 20W-50 provides an exceptionally high level of wear protection. There is no need to add a separate zinc additive.

Two main applications

1. Break-in oil for new and rebuilt standard engines

When breaking in a new or rebuilt classic Volkswagen engine, additional protection for the camshaft and tappets is important. Thanks to its high zinc content, Lucas Racing Only SAE 20W-50 is offered as a Break-In/Racing engine oil for this purpose.

After the prescribed break-in period, the oil should be replaced with a regular classic engine oil, such as Lucas Mineral High Zinc Engine Oil 20W50, which contains 1600 ppm zinc and is suitable for normal use in many standard engines.

2. Engine oil for heavily tuned engines

Heavily tuned engines, for example those equipped with a performance camshaft, stronger valve springs, higher operating speeds or significantly increased power output, may require additional wear protection.

The special formulation of Lucas Racing Only SAE 20W-50 is designed to maintain a strong protective oil film even under these extreme conditions.
