• Elite Oxidation Stability: Provides strong resistance against oxidation and thermal breakdown, effectively extending oil life and service intervals.
• Optimized Fuel Efficiency: Maximizes fuel economy by reducing mechanical drag and keeping internal engine components cleaner.
• Soot Accumulation Control: High-performance additive technology actively manages soot buildup to maintain uniform lubrication and reduce downtime.

Applications

• Diesel-powered passenger cars, SUVs, and multi-utility vehicles.
• On-road commercial transport fleets, long-haul logistics trucks, and buses.
• Agricultural machinery including high-load farm tractors and harvesters.
• Off-road construction machinery and heavy-duty industrial equipment operating under extreme conditions.

Usage

• Drain Old Fluid: Park the vehicle on level ground, warm up the engine slightly to decrease oil viscosity, unscrew the oil pan drain plug, and allow the exhausted oil to drain completely into a pan.
• Replace Oil Filter: Remove the old oil filter, apply a light coat of fresh ZPremium oil onto the rubber gasket ring of the replacement filter, and hand-tighten the new filter securely onto its housing.
• Refill Oil Reservoir: Reinstall and tighten the drain plug, open the top engine oil filler cap, place a clean funnel, and pour in the fresh ZPremium 15W40 CI4 lubricant.
• Verify Fluid Level: Secure the oil cap, idle the engine for 2 to 3 minutes to safely build uniform pressure while checking underneath for leaks, shut off the ignition, wait 5 minutes, and verify the dipstick reads at the full indicator mark.
• Responsible Disposal: Securely transfer the spent motor oil into a sealed jug and transport it to an authorized regional automotive fluid recycling depot.
