How does this oil suit the 3.0L Duramax engine?

DexosD 0W-20 is formulated to meet specifications required by modern turbo diesel engines like the LM2 3.0L Duramax, offering viscosity and additive balance for proper lubrication and cold-start flow. Using the correct grade maintains OEM tolerances and supports fuel-efficiency targets without resorting to non-approved blends.

• Meets DexosD performance requirements for diesel applications
• 0W-20 viscosity for cold starts and operating temperature protection
• Formulated to be compatible with emissions and aftertreatment systems
• Helps maintain manufacturer-expected oil pressure and flow

Is the included PF66A the right filter for my truck?

The PF66A oil filter in this kit is the updated black replacement for the discontinued PF66 blue filter and fits the LM2 3.0L Duramax used in Silverado, Sierra, Tahoe, Yukon, Suburban and Escalade models where that part is specified. Using the matched filter helps ensure proper sealing, bypass valve operation and filtration efficiency.

• PF66A is the updated, compatible replacement for PF66
• Designed to meet OEM filtration and bypass specifications
• Prevents contaminants from circulating in the engine oiling system
• Factory-equivalent fit and thread pitch for secure installation

When should I change the oil using this kit?

Typical recommended oil change intervals for this configuration are around 7,500 miles under normal driving conditions, but always follow your vehicle’s owner manual or maintenance schedule. If you tow, drive in extreme temperatures, or encounter severe duty cycles, consider more frequent changes per manufacturer guidance.

• Standard recommended interval: approximately 7,500 miles
• Shorten interval for severe-duty, towing, or extreme climates
• Follow vehicle owner’s manual for official guidance
• Use oil level checks between services to monitor consumption
