Product description

The gearbox and differential of a classic Volkswagen require reliable lubrication to protect gears and bearings against wear. A strong and dependable lubricating film is especially important in heavily loaded vehicles, such as campers, fully loaded Transporters and classic Volkswagens fitted with high-performance engines.

Lucas Heavy Duty Gear Oil SAE 80W-90 is a high-quality mineral gear oil specially developed for heavily loaded gearboxes, differentials and gear drives. Its special formula provides additional protection against friction, wear and heat build-up, even under demanding conditions.

This makes the oil particularly suitable for classic Volkswagens that regularly operate under heavy loads, such as campers on long holiday journeys, vehicles driven in mountainous areas or those fitted with more powerful engines.

Key benefits:

✓ Specially developed for heavily loaded gearboxes and differentials
✓ Ideal for campers, heavily loaded vehicles and Volkswagens with increased engine power
✓ Provides extra protection for gears and bearings
✓ Forms a strong lubricating film, even under heavy loads
✓ Reduces friction, wear and heat build-up
✓ Helps control transmission operating temperatures
✓ Protects against rust and corrosion

Maintenance and oil changes

According to the maintenance guidelines for many classic Volkswagens, the gearbox oil level should be checked every 10,000 km and topped up if necessary. The oil should be changed every 30,000 km. Consult the maintenance schedule for the specific model to confirm the correct intervals.

We recommend changing the gearbox oil immediately after purchasing a classic Volkswagen if its maintenance history is unknown. After all, there is no way of knowing how long the existing oil has been in use.

Over many kilometres, the quality of the oil deteriorates, especially when the gearbox is regularly subjected to heavy loads. When changing the oil, first loosen the filler plug on the side of the gearbox using the correct Allen key (see related products), and only then remove the lower drain plug. Clean the drain plug thoroughly and fill the gearbox until the oil reaches the lower edge of the filler opening, provided this is the specified filling procedure.

Important information for automatic transmissions

Certain classic Volkswagen automatic transmissions use separate gear oil for the differential section. The automatic transmission section and torque converter use ATF (Automatic Transmission Fluid). This SAE 80W-90 oil is not a substitute for ATF.
