What Is LIQUI MOLY Touring High Tech 15W-40?

LIQUI MOLY Touring High Tech 15W-40 is a high-performance, mineral-based engine oil developed for vehicles with established engine technology, particularly engines with higher mileage. Its formulation helps maintain a stable lubricating film under demanding operating conditions, reduce oil consumption and prevent black sludge formation.

Suitable for compatible petrol and diesel engines, including turbocharged engines, this all-season motor oil provides wear protection and helps keep engine seals flexible. It is intended for vehicles without a diesel particulate filter (DPF), subject to the vehicle manufacturer’s oil requirements.
