Look, I’m not here to tell you this is “good news” or “bad news.” I’m here to tell you GM is quietly changing strategy on the 6.2L L87, and owners like myself deserve to know. In this video I break down GM’s updated dealer guidance that transitions dealerships away from Mobil 1 Supercar 0W-40 and over to Mobil 1 FS 0W-40 once Supercar inventory is depleted. Same viscosity, same brand, but it’s not the same story—because GM is also ending reimbursement for Supercar oil and continuing reimbursement for FS, and that reimbursement policy tells you what GM considers acceptable long-term. I also connect the timing to what’s happening on the regulatory side: NHTSA opened Recall Query RQ26001 to ask a very specific question—are post-recall remedies actually working? According to the public documents, there are reports of post-remedy failures, even after recall service and, in some cases, engine replacements. I clear up the biggest point of misinformation: both Mobil 1 Supercar 0W-40 and Mobil 1 FS 0W-40 are dexosR approved, and that certification matters more than the marketing label. My biggest takeaway is simple: oil choice alone is not the full story. If you’ve had recall work done, check your invoice and make sure the oil listed is dexosR-approved 0W-40—documentation is going to matter more than ever.
