AMSOIL diesel oil guide for trucks, vans, SUVs and diesel engines<\/figcaption><\/figure>\n

For the 2022 Chevrolet Tahoe equipped with the 3.0L 6-cylinder LM2 T Diesel Turbo engine, the required oil viscosity is 0W-20. The engine oil capacity is 7 quarts when performing a change with a new filter. AMSOIL recommends using AMSOIL 0W-20 100% Synthetic Diesel Oil<\/a> (DP020QT-EA<\/a>) paired with a WIX Oil Filter<\/a> (WL10351-EA<\/a>) for optimal protection.<\/p>\n

What oil does a 2022 Chevrolet Tahoe 3.0L Diesel take?<\/h2>\n

The 2022 Chevrolet Tahoe with the 3.0L 6-cylinder LM2 T Diesel Turbo engine requires an oil viscosity of 0W-20 for all temperature ranges. The AMSOIL lookup oil grade is SEOA5. For vehicles originally using GM Dexos2, the lookup note states that a GM Dexos D licensed engine oil of the appropriate viscosity grade may be used.<\/p>\n

AMSOIL product recommendations<\/h2>\n

Based on the AMSOIL lookup data, the following products are recommended for your 2022 Chevrolet Tahoe 3.0L Diesel engine maintenance.<\/p>\n

How much transmission fluid does it take?<\/h2>\n

The capacity for the automatic transmission depends on whether the vehicle is equipped with a cooler. The AMSOIL lookup references the WSS-M2C949-A specification, noting that products meeting this are available under DEXRON ULV and MERCON ULV tradenames.<\/p>\n

Diesel maintenance notes for this vehicle<\/h2>\n

Because the 3.0L LM2 is a turbocharged diesel engine, maintenance requirements differ from gasoline V8 models. Owners should prioritize specialized diesel protocols, including monitoring Diesel Exhaust Fluid (DEF) levels and ensuring high-quality fuel filtration to protect the common-rail injection system and turbocharger components.<\/p>\n
