Caltex Delo Gold SAE 15W-40 Heavy-Duty Diesel Engine Oil 1LFull Product Description (Commercial Fleet Operation Version)Product OverviewCaltex Delo Gold SAE 15W-40 is a premium multi-grade heavy-duty diesel engine oil built with Caltex exclusive ISOSYN balanced additive technology. Specially engineered for daily high-load commercial fleets, including long-haul trucks, passenger coaches, haulage vehicles and rental construction machinery. It solves core pain points of commercial operators: frequent engine wear, short oil service life, carbon buildup, high maintenance downtime and exhaust system damage, cutting overall operation costs while guaranteeing stable vehicle attendance.Core Advantages for Commercial OperatorsHeavy-Duty Anti-Wear Protection, Minimize Breakdown LossCommercial vehicles run under full loads, steep slopes and non-stop long-distance trips, leading to continuous intense friction on pistons, crankshafts and cylinder liners. This oil instantly forms a tough, heat-resistant protective oil film that will not rupture under extreme high temperature and heavy load. It drastically reduces risks of cylinder scoring and bearing wear, avoiding unexpected roadside breakdowns and costly engine overhauls—less downtime means more revenue for your fleet.Superior Soot & Deposit Control, Stabilize Power & Reduce Fuel CostLong-hour commercial diesel combustion generates massive soot, sludge and carbon deposits, which easily block oil passages and jam piston rings, resulting in weak power and rising fuel consumption. High-concentration detergent dispersant additives continuously dissolve existing carbon and suppress new deposit formation inside engines. Sustained power output keeps your daily fuel expenditure under control for long-term operation.Excellent Thermal Oxidation Stability, Extend Drain IntervalsCommercial fleets operate round-the-clock with persistent high engine temperatures. Advanced anti-oxidation formula slows oil thickening and acid deterioration under extreme heat. Compared with regular low-grade diesel oils, it allows longer oil change cycles, reducing frequent maintenance stops, oil material expenses and labor fees, maximizing effective operation hours of each vehicle.Low-Ash Formula, Compatible with EGR & SCR Exhaust After-Treatment SystemsCheap inferior oils often clog SCR urea catalytic devices and EGR circulation components, which will trigger emission faults, traffic fines and load limits for commercial vehicles. Delo Gold adopts a low-ash balanced formula that fully protects exhaust after-treatment systems on Euro 4/Euro 5 diesel engines, eliminating risks of exhaust system repairs and administrative penalties.Wide Commercial Application RangeFreight Transport: Light trucks, medium & heavy-duty haulage trucks, semi-trailer tractorsPassenger Transport: Intercity coaches, rural shuttle buses, tour passenger vehiclesConstruction Rental Equipment: Excavators, loaders, compactors, muck trucksAuxiliary Commercial Equipment: Diesel generators, farm tractors, harvesting machinesIndustry Certifications & OEM ApprovalsMeets top industry performance standards API CI-4 / CH-4 / CG-4, ACEA E7/E3.
