When you’re protecting a flagship like the Escalade, the right oil isn’t a guess—it’s an engineering requirement. Below is a clear, year-by-year breakdown from the newest models back to the first-gen trucks. We group years that share the same specification and call out exceptions (like the Escalade-V and the 2021–2024 L87 recall update). Where it matters, we note the GM “dexos” certification your oil must carry. If you’d like us to confirm your VIN-specific spec or perform an oil service with GM-approved oil and filters, the Turan-Foley Cadillac team is ready to help.
2026–2021 Escalade (5th Gen, 6.2L Gas L87)
For standard gasoline Escalade models with the 6.2L L87 V8, the owner’s manual specifies full-synthetic SAE 0W-20 that meets GM dexos1 (latest generation). Always verify on your oil fill cap and in the manual; that’s GM’s source of truth.
Important exception for 2021–2024 L87 engines: GM recall N252494001 directs dealers to inspect affected engines. If your engine passes inspection, GM updates the requirement to dexosR 0W-40 (and replaces the oil cap and adds an owner-manual insert). If the engine fails, it’s replaced and remains on 0W-20 dexos1. This update is documented in GM’s recall bulletin and reported by major outlets. Follow whatever your updated cap and paperwork state.
Bottom line:
• 2025–2026 L87 (and any 2021–2024 not updated by the recall): dexos1 full-synthetic 0W-20.
• 2021–2024 L87 vehicles updated under the recall: dexosR full-synthetic 0W-40.
2026–2023 Escalade-V (6.2L Supercharged LT4)
The Escalade-V uses GM’s high-output supercharged 6.2L. It requires dexosR 0W-40—this is a different oil family than standard Escalade. GM’s manual calls out dexosR 0W-40 (Mobil 1 ESP Formula dexosR 0W-40). Do not substitute 0W-20 here.
2026–2021 Escalade (3.0L Duramax Diesel LM2/LZ0)
Diesel Escalades need engine oil that meets GM dexosD in SAE 0W-20. This is explicitly stated in GM’s Duramax 3.0L Diesel Owner Manual Supplement: “Use engine oils that meet the dexosD specification… Use SAE 0W-20 viscosity grade.”
2020–2015 Escalade (4th Gen, 6.2L L86)
These K2-generation Escalades specify full-synthetic SAE 0W-20 that meets dexos1. That requirement is spelled out in the owner’s manual and applies across this generation.
2014–2007 Escalade & Escalade Hybrid (3rd Gen)
Third-gen gas Escalades are a 5W-30 era. The 2014 owner’s manual specifies SAE 5W-30 and references the dexos1 standard for the oil. In very cold climates, 0W-30 may be used. Earlier third-gen manuals specify 5W-30 meeting GM’s prior standards (e.g., GM6094M for most gas engines; the Hybrid’s 6.0L called for oils meeting GM4718M). If your 2007–2010 truck still shows the earlier GM spec in the manual, follow it or use a modern dexos1 5W-30 that supersedes those legacy specifications.
2006–2002 Escalade (2nd Gen)
The second-gen trucks call for SAE 5W-30. In extreme cold (below −20°F/−29°C), SAE 0W-30 may be used for easier starts. GM’s manuals from this period also reference the GM6094M oil standard; a current dexos1-licensed 5W-30 satisfies and exceeds that legacy requirement.
2000–1999 Escalade (1st Gen)
First-generation Escalades also specify SAE 5W-30 (with 0W-30 permitted in extreme cold). As with the early 2000s trucks, GM6094M was the contemporary spec; a modern dexos1-licensed 5W-30 is an appropriate present-day equivalent.
Pro Tips From Our Shop
• Check the cap: If your oil fill cap says 0W-40 (post-recall L87) or 0W-20 (standard L87), follow the cap and updated paperwork. The cap is updated alongside the recall work for 2021–2024 L87 engines that remain in service.
• Match the dexos spec: Gasoline Escalades use dexos1 (0W-20 or 5W-30 depending on year), the Escalade-V uses dexosR 0W-40, and the Duramax uses dexosD 0W-20. Using oil without the correct dexos approval can jeopardize protection and warranty coverage.
• Confirm by VIN: Some 2021–2024 L87 vehicles changed viscosity requirements under the recall. We can check your VIN, the cap, and update records in minutes.
Conclusion
Choosing the correct oil for your Escalade comes down to engine, model year, and the proper GM dexos approval. In short: late-model gas L87s are 0W-20 dexos1 unless updated by the 2021–2024 recall to 0W-40 dexosR; the Escalade-V is always dexosR 0W-40; Duramax models are dexosD 0W-20; earlier generations are 5W-30 (or 0W-30 in extreme cold) per their manuals. If you want a quick, no-nonsense answer for your exact VIN and driving conditions, Turan-Foley Cadillac’s service advisors will verify the spec and service your Escalade with GM-approved oil and an OEM filter.
