Purpose and Specifications
Liqui Moly Diesel Synthoil 5W40 1L is a fully synthetic diesel engine oil that delivers top performance year-round. It flows easily at cold starts down to -30°C for instant protection and stays thick up to 150°C under heavy loads, keeping your engine safe from wear in extreme temps.

- Reduces emissions and fuel use
- Miscible with other motor oils
- Shelf life of 5 years when stored properly
