Liqui Moly Leichtlauf High Tech 5W-40 Motor Oil — 5 L Synthesis, Fully Synthetic Low-Friction

This 5-liter bottle contains Liqui Moly's Leichtlauf High Tech 5W-40, a synthesis-technology motor oil developed for modern gasoline and diesel engines (excluding vehicles with DPFs). Designed to support extended drain intervals where permitted by the vehicle manufacturer, the formulation combines advanced base oils and a targeted additive package to lower friction, help maintain engine cleanliness and sustain oil pressure under varying loads.

How does this oil improve cold starts and everyday drivability?

The 5W rating ensures the oil flows quickly at low temperatures, so moving parts receive lubricant immediately after start-up. That rapid circulation reduces initial wear and contributes to smoother engine operation in cool conditions without sacrificing protection in heat.

• Fast oil delivery at low temperatures for quicker lubrication
• Maintains stable oil pressure across engine speeds
• Low-friction base oils help reduce mechanical drag

Can it support long service intervals and heavy-duty driving?

The synthetic blend is engineered for ageing resistance and high shear stability, which helps the oil retain protective properties over longer periods. When used according to manufacturer guidelines, it can be suitable for extended oil-change intervals and demanding operating conditions.

• High ageing and shear stability for longer oil life
• Compatible with commonly available engine oils for top-ups
• Formulated for turbocharged and multi-valve engines under load

Which engines and approvals make this oil a fit for my vehicle?

Leichtlauf High Tech 5W-40 is intended for modern gasoline and diesel units—particularly multi-valve and turbocharged designs—excluding diesel engines requiring a particulate filter. It carries multiple manufacturer approvals, making it suitable for vehicles built to those specifications.

• Suitable for gasoline and diesel engines without DPF
• Approvals include BMW Longlife-01, MB-Approval 229.5, Porsche A40
• Also matches Renault RN 0700/0710 and VW 502 00/505 00 requirements

Will this oil help keep my engine clean and efficient?

The formulation includes detergents and dispersants designed to limit deposit formation and support combustion cleanliness. It is tested for compatibility with catalytic converters and designed to support turbos while helping to reduce fuel consumption and emissions when used as specified.

• Engine cleanliness additives reduce sludge and deposits
• Compatible with catalytic converters and turbochargers
• Designed to support fuel economy and lower emissions

Who is this for: Liqui Moly Leichtlauf High Tech SAE 5W-40 (5 L) is aimed at owners of modern gasoline and diesel cars without DPFs who want a dependable, fully synthetic oil for year-round driving, extended drain intervals where permitted, and engines that demand reliable protection under higher loads or frequent cold starts. Always consult your vehicle handbook for recommended viscosity and manufacturer approvals before changing oil.
