New DEUTZ Engine Oil Specifications

Back in 2007, more than 10 years ago, DEUTZ introduced an approval system for engine oils. For the first time it was possible to approve an oil according to one of the DEUTZQuality Classes (DQC). Since then, the different quality levels have been adapted several times to meet the latest requirements and to reflect the current state of the art.

In 2011, the specifications have been divided into conventional engine oils (DQC X-10) and oils with reduced SAPScontent (sulphated ash, phosphorous, sulfur), also known as DEUTZ DQC X-10 LA. This was necessary due to the current emissions legislation and the associated use of exhaust aftertreatment systems.

In 2016, a special approval list for TTCDengines has been released, which also includes our TITAN CARGO MAXX SAE 5W-30 and SAE 10W-40. These engines have very high requirements regarding piston cleanliness and require a suitable oil.

New emission limits in the off-road area (EU Stage V from 2019), longer drain intervals, and new engine oil specifications of API (API CK-4) and ACEA (ACEA 2016) are now the driver to increase the requirements of the Deutz Quality Classes again and to publish the most recent DEUTZ DQC X-18.

DEUTZ DQC X-18

The new specifications are set up like the previous ones. On the following chart we would like to give you an overview of the respective quality levels. Please note: Approved engine oils of a quality class may also be used in applications that require a lower quality class. You can find information on the prescribed lubricant class and information on drain intervals in the corresponding manual or the DEUTZ Technical Circular 0199-99-01217/3.

DEUTZ has planned enough time for the conversion from DEUTZ DQC X-10 to DEUTZ DQC X-18. Approvals according to DQC X-10 remain valid until 31.12.2024 at the latest.
