By using Mobil Delvac 1 5w-40 engine oil in the company's Hidromek HMK-370 crawler excavator, oil change times have been increased to 1,000 hours, and the annual cost of spare parts and oil is 10,500 TL. Savings have been achieved.

15W-40 heavy diesel engine oil is currently used in the Hidromek HMK-370 crawler excavator in the company, and the engine oil is changed every 250 hours, and the oil filter set is also replaced with each oil change.
Considering the Hidromek HMK-370 crawler excavator in our Customer Company, a recommendation was made to switch to the MOBILE DELVAC 1 5W/40 product, which has API CI-4 PLUS specifications to extend engine oil and filter change hours, providing high engine protection and allowing long oil changes.
Mobil Delvac 1 5W-40 engine oil in the Hidromek HMK-370 crawler excavator was regularly monitored, and engine oil and oil filter changes were increased to 1,000 hours. At the end of this oil change period, 10,500 TL was saved annually in oil costs and spare parts costs compared to the previously used engine oil.
