TL;DR API SP + ILSAC GF-6A certified · current top-tier spec for most 2020+ gasoline engines. GM dexos1 Gen 3 and Honda/Acura HTO-06 approvals confirmed on label. The 20,000-mile drain claim is aspirational: community UOA data supports 10,000·15,000 miles on typical daily-driver use. Prop 65 warning applies.
PAO Group IV full synthetic certified to API SP + ILSAC GF-6A. Carries GM dexos1 Gen 3 and Honda/Acura HTO-06 approvals · among the broadest OEM coverage for an extended-drain synthetic. BITOG community UOA data shows healthy TBN at 10,000·15,000 miles on daily-driver use; the 20,000-mile label interval applies under highway-dominant conditions only.
Best for 2020·2026 GM owners (dexos1 Gen 3 required) and Honda/Acura models specifying 5W-30 (HTO-06 required) who want extended-drain OEM-backed full synthetic. Skip if cost-per-quart is the priority · conventional oil at your OEM spec costs far less at 5,000-mile intervals. Confirm the OEM approval list on Mobil's product page before relying on this oil for warranty documentation on other vehicle applications.
The SDS classifies this as not hazardous · no signal word, no H-codes at mixture level. H304 does not apply (KV40 = 57.2 cSt, above the CLP aspiration threshold). The Prop 65 warning covers the ZDDP additive (CAS 2215-35-2), a California reproductive hazard per SDS §15, and used-oil skin exposure · IARC classifies mineral oil mist (from used-oil combustion byproducts) as a Group 1 carcinogen based on occupational studies. The SDS on file was last revised in 2019 · 7 years old; the H-codes here reflect that revision and may not capture additive changes since. Used oil goes to collection · not down the drain. AutoZone, O'Reilly, and most municipal hazardous-waste facilities accept it.
The 20,000-mile claim is backed by Mobil's engine-protection guarantee · but the guarantee covers engine damage, not that every engine in every driving condition will see the oil last 20,000 miles. Community used-oil analysis (UOA) data from BITOG forum threads shows Mobil 1 EP maintaining healthy TBN and low oxidation markers at 10,000·15,000 miles on normal daily-driver use. Severe-duty driving (lots of short trips, towing, extreme temperatures) depletes oil life faster. The 20,000-mile target is achievable under favorable highway-dominant conditions; 10,000·15,000 miles is more typical for average stop-and-go use.
Yes. Mobil 1 Extended Performance 5W-30 carries GM dexos1 Gen 3 approval (designation M8836F, visible on the front label). GM dexos1 Gen 3 is the current approval required for 2020+ GM vehicles. Using dexos1 Gen 3-approved oil is required to maintain GM's powertrain warranty for affected model years.
API SP is the current top-tier gasoline engine oil specification as of 2026, succeeding API SN Plus. ILSAC GF-6A adds fuel economy and chain-wear protection on top of API SP · required for most 2020+ gasoline passenger vehicles from Toyota, Honda, Ford, and GM. Using an API SP + ILSAC GF-6A oil ensures deposit control, oxidation stability, and LSPI (low-speed pre-ignition) protection that older specs (API SN, SM) may not fully provide for turbocharged or GDI engines.
Standard Mobil 1 Full Synthetic is certified to API SP + ILSAC GF-6A with recommended drain intervals of 7,500·10,000 miles. Extended Performance uses a higher-treat additive package (higher TBN, more oxidation inhibitors) designed to support the longer drain interval claim. The ZDDP anti-wear additive package is similar between lines; the primary difference is additive depletion resistance at extended drain intervals.
Mobil 1 Extended Performance 5W-30 carries Honda/Acura HTO-06 approval (visible on the back label). Honda Genuine Motor Oil is Honda's private-label product; any oil meeting the HTO-06 spec is equivalent for warranty purposes. The HTO-06 approval on this 5W-30 covers engines that specify a 5W-30 viscosity grade · it does not substitute for applications requiring 0W-20.
