Diesel maintenance notes for this vehicle

  • Oil Level Verification: After refilling the engine oil, always check the level to ensure accuracy.
  • Seal Replacement: Always replace the oil drain plug seal when performing an oil change.
  • Transfer Case Identification: Check the tag on the case for proper identification of transfer case requirements.
  • Coolant Mixing: If using AMSOIL Propylene Glycol Antifreeze, it is a concentrate and requires mixing with distilled or high-quality water.

Common diesel oil-related concerns and how AMSOIL products may help

Concern Why it matters AMSOIL product How it may help Limitation
Engine Wear Diesel engines face high pressure and friction. DP020QT-EA Delivers up to 6X more wear protection than leading industry standards in specific tests. Requires regular intervals.
Temperature Extremes Cold starts or high heat can degrade oil. DP020QT-EA Excels in hot and cold temperature extremes. Not a substitute for proper maintenance.
Transmission Heat Heavy towing causes fluid breakdown. ULVPK-EA Withstands the rigors of heavy towing and elevated temperatures. Check for leaks regularly.

Common maintenance concerns for this vehicle

Based on owner reports, owners should monitor several key areas:

  • Engine Performance: Some users have reported issues regarding loss of propulsion or engine stalling.
  • Oil Pressure: Monitoring for low-oil-pressure warnings is advised, especially if unusual noises are detected.
  • Lighting Systems: Ensure daytime running lights (DRLs) function correctly in relation to headlights.

Recall, TSB, and manufacturer communication notes

Official NHTSA research indicates the following recalls for the 2022 GMC Yukon:

  • Seat Belt Fasteners: A recall (Campaign 22V617000) was issued regarding improperly formed rivets in third-row seat belt buckle assemblies.
  • Exterior Lighting: A recall (Campaign 22V903000) involves software for the lighting control module where DRLs may not deactivate when headlights are on.

Disclaimer: Always verify open recalls by checking your specific VIN through official GMC channels or the NHTSA website.

About this vehicle

The 2022 GMC Yukon is a premium full-size SUV within General Motors’ large utility lineup, often associated with high-end trims like the Denali. This specific model features the 3.0L 6-cylinder Duramax diesel turbo engine (Engine Code [T] LM2 T), which is designed for those requiring high torque and efficient long-distance cruising.

The Duramax nameplate represents GM’s specialized diesel technology, commonly utilized in vehicles intended for heavy towing and large family transport. Because this vehicle utilizes a modern diesel powertrain, maintenance often focuses on adhering to strict emissions standards and maintaining the integrity of the high-pressure common rail fuel system. Owners typically prioritize fuel system cleanliness, turbocharger health, and Diesel Exhaust Fluid (DEF) management to ensure optimal performance.

As part of a modern generation of GM SUVs, this vehicle is built for heavy-duty passenger transport, making specialized lubrication for the engine, transmission, and transfer case essential for long-term reliability under load.

Common questions about this vehicle’s diesel oil and maintenance

How much oil does my 3.0L Duramax take?

It takes 7 quarts of 0W-20 oil with a filter change.

What is the correct torque for the oil drain plug?

The oil drain plug should be torqued to 18 ft/lbs.

Can I use Dexos2 oil in this diesel engine?

The AMSOIL lookup note states that vehicles originally using GM Dexos2 may use a GM Dexos D licensed engine oil of the appropriate viscosity grade.

What transmission fluid is required for the 10-speed transmission?
