6-Pack Mobil 1 SAE 5W-40 Turbo Diesel Truck Full Synthetic Motor Oil, 1 QT

Mobil 1 SAE 5W-40 Turbo Diesel Truck Full Synthetic Motor Oil is engineered for the extreme demands of heavy-duty diesel engines — including turbocharged pickups, work trucks, and mixed-fleet vehicles. This advanced full synthetic formula provides superior protection versus conventional 15W-40 oils, withstanding the intense pressures of towing, hauling, and off-road use while managing the high soot load inherent in modern diesel combustion.

  • Mixed-Fleet Versatility: Meets API CK-4, CJ-4, CI-4 PLUS, and SN specifications one oil for both heavy-duty diesel trucks and gasoline-powered vehicles across your fleet.
  • Extreme Temperature Range: Maintains a stable lubricating film at high operating temperatures and stays fluid down to -40°C/-40°F for faster, safer cold starts in harsh climates.
  • Soot & Deposit Control: Formulated to handle elevated soot production in modern diesel engines, preventing sludge buildup and maintaining engine cleanliness over extended drain intervals.
  • Enhanced Wear Protection: Stronger film strength on camshafts, bearings, and cylinder walls extends engine life and reduces the risk of costly repairs.

Specs: SAE 5W-40 | API CK-4, CJ-4, CI-4 PLUS, CI-4, CH-4 / SN, SM, SL | EGR Compatible | 6 × 1-Quart Bottles (6 qt total)
Best For: Turbocharged diesel trucks, heavy-duty pickups, and mixed gas/diesel fleets
Drain Interval: Follow vehicle manufacturer guidelines

Frequently Asked Questions (FAQs)

What are the main benefits of using Mobil 1 5W-40 for diesel trucks?
Mobil 1 Turbo Diesel Truck 5W-40 is an advanced full synthetic oil engineered to extend engine life. It provides superior thermal stability to fight sludge and deposits, enhanced film strength for high-temperature protection, and exceptional low-temperature pumpability for reliable cold-weather starts down to -48°C (-54.4°F)
Can I use this oil in a gasoline engine or a mixed fleet?
Yes. While optimized for diesel, this oil meets or exceeds API SN/SM specifications for gasoline engines. This makes it an ideal "one-oil" solution for mixed fleets containing both heavy-duty diesel trucks and gasoline-powered vehicles.
Is Mobil 1 5W-40 compatible with Exhaust Gas Recirculation (EGR) systems?
Absolutely. It is specifically formulated to handle the high soot levels and increased operating temperatures common in modern low-emission diesel engines equipped with EGR systems.
How does 5W-40 compare to standard 15W-40 conventional oil?
The 5W-40 synthetic formula flows significantly faster at low temperatures than conventional 15W-40, reducing engine wear during the critical startup phase. Additionally, it offers better resistance to oxidation and potential fuel economy benefits due to reduced internal friction.
Will using this synthetic oil void my vehicle's warranty?
No. As long as your vehicle requires an API-certified oil (like CK-4, CJ-4, or CI-4 Plus), using Mobil 1 will not void your warranty. It meets or exceeds the requirements of major OEMs like Ford, Cummins, Mack, and Volvo.
