Deutz DQC IV-18LA
Deutz DQC IV-18LA is a lower SAPS* lubricant specification designed for use in high performance diesel and gas engines, offering extended oil drain intervals. These engines may have closed crankcase ventilation, steel pistons (TTCD) and the need for extended oil drain intervals. Most commonly this lubricant specification is used in the latest off-highway equipment meeting Stage V European emissions and US Tier 4 Final where advanced aftertreatment systems such as Diesel Particulate Filters (DPFs) are fitted.
Deutz DQC IV-18LA oils are typically SAE 10W-40, 10W-30 or 5W-30 viscosity grades, based on API Group III or Group III & Group II base oils mixtures.
