Ideal for mixed fleets and European vehicles
Drivers of petrol or diesel cars, light trucks and heavy-duty vehicles needing a single coolant that meets European specifications and OEM approvals will find this fluid suitable. Buyers whose vehicles require a different chemistry such as OAT-only or conventional green formulas should select an alternative product.
Service life up to 150000 miles or 5 years
In light-duty service the coolant is rated for 150000 miles or five years, while heavy-duty use is rated for 300000 miles or three years. This interval is the primary figure to check against the vehicle manufacturer’s maintenance schedule before purchasing.
