15W-40 all-season engine oil for classic gasoline and diesel vehicles with a robust mineral oil profile and broad everyday usability.
15W-40 DBV all-season engine oil is a classic multigrade oil for vehicles that require a solid mineral oil with a wide range of applications. The product is aimed at gasoline and diesel engines with and without turbocharging and remains an economical solution, especially for the existing vehicle fleet.
Its strength lies less in modern specialization and more in robust everyday usability. If you do not need longlife intervals or strict low-SAPS specifications, this is a straightforward 15W-40 for daily workshop and vehicle operation.
Particularly for older passenger cars and light-duty applications, the product remains relevant because it combines simple approval logic with reliable engine protection.
Suitable for gasoline and diesel engines with and without turbocharging where ACEA A3/B4, API SN and traditional requirements such as MB 229.1, Fiat 9.55535-G2/D2 or VW 501.01/505.00 apply.
