The 1980 Volkswagen Dasher is a distinct model in the lineage of compact vehicles from the German manufacturer. When it comes to engine oil, the correct choice is vital for this engine code YG H. The recommended viscosity for this specific engine is 20W-50, which is particularly suitable for temperatures above -10°C. For colder conditions between -10°C and 10°C, a 20W-20 viscosity is suggested. In moderate climates ranging from -15°C to 30°C, a 15W-40 or 15W-50 can be used. The engine requires 3.2 quarts of oil when performing a full change including the AMSOIL Oil Filter or WIX XP Oil Filter. It is crucial to adhere to these volume specifications to ensure adequate lubrication without overfilling, which can lead to pressure issues. The oil drain plug must be torqued to 22 ft/lbs during service to prevent leaks or damage to the threaded holes.
Filtering the oil is equally critical to the engine’s health. The AMSOIL Oil Filter (EAO34-EA) is designed to complement the synthetic motor oil, providing extended service life and capturing contaminants that would otherwise cause wear. Alternatively, the WIX XP Oil Filter (51516XP-EA) is a high-performance aftermarket option that utilizes premium media to outperform standard OEM filters. Both options ensure that the circulating oil remains clean, allowing the engine’s moving parts to slide freely and efficiently. For air intake, the WIX Air Filter (42133-EA) is recommended to keep dust and debris from entering the combustion chamber, preserving the integrity of the internal components.
Moving to the cooling system, the 1980 Dasher holds 6.3 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. Maintaining this system is essential for preventing overheating, which can be particularly damaging to older aluminum heads and gaskets. AMSOIL offers two distinct AMSOIL Propylene Glycol Antifreeze and Engine Coolant options for this application. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that protects against corrosion and freezing down to -34°F. It is phosphate-, nitrate-, and nitrite-free, making it safe for all metals and hoses. For those who prefer a concentrated solution, the AMSOIL AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers an even longer service interval, protecting up to 150,000 miles or 5 years. Both fluids are compatible with various antifreeze colors and provide superior protection against metallic corrosion and erosion.
The transmission system in the Dasher requires specific attention depending on the configuration. For the 3-speed automatic transmission, the fluid capacity is 6.3 quarts for a total fill or 3.2 quarts for an initial fill. The recommended fluid for this vehicle is the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid (ATFPK-EA). This fluid is engineered to remain fluid in sub-zero temperatures and provides reserve protection during heavy use, which is beneficial if the vehicle is used for towing or driving in difficult terrain. An alternative is the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid (OTFQT-EA), which is known for its excellent cold-weather performance and ability to promote smooth, shudder-free shifts. For the manual transmission, no specific fluid recommendations are listed, but owners should consult their specific service manual for the appropriate GL rating.
For the differential and transfer case, the front differential requires 1.7 pints of AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube. The AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube is a top choice for this application. It contains friction modifiers suitable for limited-slip applications and helps control thermal runaway. If different operating temperatures are anticipated, the AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube or 75W-110 variants are also available, providing robust protection against rust, corrosion, and wear across a wide temperature spectrum. These synthetic gear lubes are designed to extend the life of the oil, seals, and equipment while reducing operating temperatures, which is crucial for older differential designs.
Brake safety cannot be overstated, especially for a vintage vehicle. The 1980 Volkswagen Dasher utilizes hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid that meets DOT 3 and DOT 4 standards. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is formulated to provide a stable viscosity over a wide temperature range, ensuring excellent responsiveness for ABS and traction-control systems. This fluid helps maintain the integrity of the braking system, preventing moisture absorption and boiling points that could lead to brake fade during heavy use.
