3. Application and Usage
3.1. Compatibility
This motor oil is suitable for both gasoline and diesel engines. It is specifically formulated for engines equipped with Diesel Particulate Filters (DPF) and is compatible with Start-Stop automatic systems and hybrid vehicles.
It is miscible with all commercially available motor oils. However, for optimal performance, it is recommended to use this product exclusively or as part of a complete oil change.
3.2. Setup and Operating Instructions
- Check Vehicle Manual: Always refer to your vehicle's owner's manual for the correct oil specification (viscosity, API/ACEA ratings) and required oil volume.
- Engine Temperature: For an oil change, ensure the engine is warm but not hot to allow for proper drainage.
- Drain Old Oil: Safely drain the old engine oil completely.
- Replace Filter: Install a new oil filter according to your vehicle manufacturer's instructions.
- Add New Oil: Carefully pour the Liqui Moly Longtime High Tech 5W-30 motor oil into the engine's oil filler cap, using a funnel to prevent spills. Add the recommended volume as per your vehicle manual.
- Check Oil Level: After adding the oil, wait a few minutes for it to settle. Check the oil level using the dipstick. The level should be between the minimum and maximum marks. Add more oil if necessary, but do not overfill.
- Run Engine: Start the engine and let it run for a few minutes to circulate the new oil. Check for any leaks.
- Final Check: Turn off the engine, wait a few minutes, and re-check the oil level. Adjust if needed.
