The truck manufacturer, DAF, has decided to release its own engine lubricant standards.


The 2 DAF specifications are called :

PSQL 2.1 E LD : This standard is intended for long drain intervals. Our product YORK FOCUS QTM SAE 10W/30 has the performance level of this product. DAF is not ready yet for official approvals, however the process is nearing completion.

PSQL 2.1 E : This standard will be for standard drain intervals. We are currently reviewing our YORK 1049 SAE 10W/30 lubricant to ensure that it will perform well enough.
