PEAK Heavy Duty Diesel Synthetic Blend Motor Oil SAE 15W-40

PEAK® Heavy Duty Diesel 15W-40 CK-4/SN Synthetic Blend Motor Oil is designed to meet all OEM's latest diesel engine high temperature performance demands and deliver real cold weather performance. Recommended for use in high-performance, low-emission diesel engines equipped with EGR (Exhaust Gas Recirculation), Diesel Particulate Filters and SCR (Selective Catalytic Reduction) systems.

• Enhanced Oxidation Control - dual anti-oxidant chemistry extends stay-in-grade viscosity protection life. Combats acid formation and thermal viscosity breakdown
• Superior Corrosion Prevention – robust chemistry boosts and extends reserve alkalinity capability neutralizing harmful corrosive acid formation up to 2X longer than previous API CJ-4 heavy duty motor oils
• Outstanding Deposit Control - outstanding piston and cylinder deposit control surpassing all new performance standards for engine cleanliness
• Improved Oil Aeration Control – improves ability to lubricate parts, mitigate oil flow cavitation and control oxidation effectively
• Approved for OEM extended service drain intervals in on-highway medium to heavy duty engine applications
• Synthetic blend formula promotes low temperature pumpability providing faster oil flow for cold weather start-up protection
• High viscosity index delivers significant fuel savings benefit and same superior engine lubrication protection as SAE 15W-40
