Change the engine oil after the first 50 hours of operation and then at every 250 hours thereafter.3. Select the oil viscosity based on the ambient temperature where the engine is being operated. See SAEService Grade Viscosity Chart (Figure 3).4. ISUZU does not recommend the use of engine oil “additives.”Additional Technical Engine oil Requirements:The engine oil must be changed when the Total Base Number (TBN) has been reduced to 2.0. TBN (mgKOH/g) test method; JIS K-201-5.2-2 (HCI), ASTM D4739 (HCI)(2) Engine oil viscositySelect the appropriate engine oil viscosity based on theambient temperature and use the SAE Service Grade ViscosityChart in Figure 3.Figure 3
