Why Is GM Recalling the 6.2L V8?

In 2025, GM issued a major engine recall affecting its 6.2L V8 (L87) engines due to potential defects in the crankshaft and connecting rods. The issue could result in engine damage or loss of propulsion—especially if the wrong oil is used under high-stress conditions.

Affected Models (2021–2024)

This recall impacts several popular models, including:

• Chevrolet Silverado 1500

• Chevy Tahoe and Suburban

• GMC Sierra 1500

• GMC Yukon and Yukon XL

• Cadillac Escalade & Escalade ESV

2025 models are excluded thanks to manufacturing changes post-June 2024.

The New GM Oil Specification: 0W-40 dexosR

GM now recommends switching from 0W-20 to 0W-40 dexosR for many 6.2L V8 engines that pass inspection. This heavier oil helps protect engine components under load and high temperatures—conditions where factory-fill 0W-20 may fall short.

🔍 Why 0W-40?

• ✅ Better high-temp protection

• ✅ Increased film strength for wear control

• ✅ More robust under towing and performance use

⚠️ What This Means for You

• Keep using 0W-20 until you're notified or inspected by a dealer

• Switch to 0W-40 dexosR if your oil cap or dealer advises it

• Avoid warranty issues by following GM's official service bulletin

• Expect slightly higher oil pressure and possible minor MPG changes
