Volkswagen 1.8T and 2.0L Molygen Oil Change Guide
Regular oil changes help protect the bearings, camshaft, cylinder surfaces, and turbocharger found in applicable Volkswagen engines. This guide covers compatible Volkswagen Beetle, Golf, GTI, Jetta, GLI, and Jetta Wagon models using the 06A115561B-style spin-on oil filter.
The complete Liqui Moly Molygen 5W-40 Volkswagen Oil Change Kit includes five liters of engine oil, a premium spin-on filter, replacement drain plug, and sealing washer.
Why Use Molygen 5W-40?
Liqui Moly Molygen New Generation SAE 5W-40 uses an advanced additive system designed to reduce friction between internal engine components.
Its benefits include:
- Reliable lubrication during cold starts
- Strong high-temperature protection
- Reduced friction and engine wear
- Resistance to sludge and deposits
- Stable oil pressure under demanding conditions
- Support for turbocharged engine protection
Molygen oil has a fluorescent green appearance. This is normal and should not be mistaken for coolant contamination.
Required Oil Specification
The gasoline engines covered by this guide generally require oil meeting VW 502 00. The Molygen oil supplied in the kit also meets VW 505 00, ACEA A3/B4, and API SN requirements.
Always confirm the required oil specification in the vehicle documentation.

Oil Change Procedure
- Park the vehicle on a level surface.
- Allow the engine to warm slightly and switch it off.
- Engage the parking brake and safely raise the vehicle if necessary.
- Remove the lower engine cover where equipped.
- Position a drain pan beneath the oil pan.
- Remove the drain plug and allow the used oil to drain completely.
- Remove the old spin-on oil filter.
- Confirm that the old filter gasket was removed with the filter.
- Lightly lubricate the new filter gasket with fresh engine oil.
- Install the new filter according to its installation instructions.
- Install the replacement drain plug and sealing washer.
- Add the initial quantity of fresh engine oil.
- Start the engine briefly and verify that the oil-pressure warning turns off.
- Inspect the filter and drain plug for leaks.
- Switch off the engine and wait several minutes.
- Check the dipstick and add oil gradually as required.
- Reinstall the lower engine cover.
- Reset the maintenance reminder where applicable.
Important Filter Installation Tip
Before installing the new filter, verify that the old rubber filter gasket is not stuck to the engine. Installing a new filter over the old gasket creates a double-gasket condition that can cause a major oil leak.
Tighten the filter according to the filter manufacturer’s directions. Excessive tightening can damage the gasket and make removal difficult during the next service.
Confirm Compatibility
Confirm that the vehicle:
- Has a compatible 1.8T or 2.0L gasoline engine
- Requires VW 502 00 engine oil
- Uses spin-on filter reference 06A115561B
- Uses the supplied drain plug style
The filter is used in several different applications, so its part number alone does not confirm complete kit compatibility.
