Purpose and Specifications

MOTUL Cetane Booster Diesel EFS is a premium diesel fuel additive designed to boost cetane number for more powerful combustion, clean injectors and fuel systems, and restore engine performance. This 0.3-liter bottle treats up to 30 liters of diesel fuel, improving cold starts even at temperatures down to -10°C and reducing fuel use by up to 5% on long drives.

It removes gum, varnish, and deposits from injectors, high-pressure pumps, and combustion chambers without harming fuel lines or filters. Safe for all diesel engines including turbocharged ones with DPF systems, it protects against oxidation and microbial growth for smoother idling and stronger acceleration.

When to Use / Replace?

Use one bottle every 5,000 km or 6 months for maintenance, or double dose for heavy deposits. Ideal before technical inspections to cut smoke and emissions, or with low-quality fuel on road trips. Shelf life is 3 years unopened; store below 25°C.
