GM L87 Recall Update: Oil, Engines & Stabilitrak

In this video, we’re leveling set on several active and developing topics surrounding the GM 6.2L L87 recall and other issues affecting 2021–2024 GM trucks and SUVs.

This is not speculation.
This is sourced reporting — and analysis you can verify yourself.

We cover:

• The switch to Mobil 1 FS 0W-40 for L87 recall field actions
• Replacement engine questions — new vs reman
• Stabilitrak / brake system warning reports
• Body-to-chassis ground strap concerns

🔬 Oil Testing Series (Coming Soon)

I will be performing oil analysis comparisons between:

• 2022 Cadillac Escalade 6.2L (recall-affected, passed inspection)

If you’re interested in real data and long-term comparisons — make sure you’re subscribed.
