Liqui Moly Longtime High Tech 5W-30 Fully Synthetic Diesel Oil — 5 L, Low‑SAPS for DPF & Extended Intervals

LIQUI MOLY Longtime High Tech SAE 5W-30 is a 5-liter, fully synthetic, low-SAPS diesel engine oil formulated for modern diesel motors with particulate filters and extended service intervals.

This engine oil is engineered to meet the needs of contemporary diesel vehicles that require low-ash formulations to protect diesel particulate filters (DPF) while supporting prolonged oil change schedules recommended by manufacturers. The blend is fully synthetic for stable viscosity across temperatures and is intended for use in diesel engines where OEM specifications call for a 5W-30 low-SAPS lubricant.

How does this oil work with diesel particulate filters (DPF)?

Longtime High Tech SAE 5W-30 uses a low SAPS (sulfated ash, phosphorus, sulfur) additive package designed to limit ash-forming residues that can clog DPF systems. By reducing deposits, it helps maintain the filter’s regeneration behavior and service life when the vehicle’s maintenance intervals are observed.

• Low SAPS formulation to minimize particulate ash.
• Compatible with vehicles specified for low-ash oils.
• Helps maintain DPF function under normal operating conditions.

What engines and service intervals are suitable for this oil?

This product targets diesel engines that require a 5W-30 low-SAPS lubricant and that support extended oil change intervals as defined by the vehicle manufacturer. Always follow the OEM service schedule and consult the owner’s manual or service department to confirm compatibility with model-specific requirements.

• Designed for diesel engines, especially those with DPFs.
• Formulated for use where manufacturers allow extended drain intervals.
• Check vehicle handbook for exactly matching specifications before use.

What performance and protection can I expect on a daily basis?

As a fully synthetic 5W-30, it delivers consistent cold-start flow and stable film strength at operating temperature, which supports engine lubrication across a wide range of driving conditions. While it helps reduce wear and maintain viscosity control, actual performance depends on engine condition and adherence to proper maintenance.

• Low-viscosity, fully synthetic base oils for faster lubrication at startup.
• Stable viscosity for reliable protection at operating temperature.
• Reduced deposit formation to support cleaner combustion chambers.

How should I store and use the 5 L container?

The product arrives in a 5-liter pack sized for workshop or home use; store it upright in a cool, dry place away from direct sunlight and extreme heat. When changing oil, dispose of used oil and containers according to local regulations and use the recommended quantity specified by the vehicle manufacturer.

• Package dimensions approximately 9.652 x 31.75 x 24.638 cm for convenient handling.
• Keep sealed until use; keep away from open flames or high heat.
• Follow local recycling and disposal rules for used oil and containers.

Who is this for? LIQUI MOLY Longtime High Tech SAE 5W-30 is aimed at owners and technicians of modern diesel cars and light commercial vehicles that require a low-SAPS, fully synthetic 5W-30 oil—especially where manufacturers recommend extended oil change intervals and compatibility with diesel particulate filters. It’s suitable for workshop inventory and for private owners who maintain their vehicle according to OEM service recommendations. Always confirm the oil meets your vehicle’s required approvals before use.
