TL;DR API SP + ILSAC GF-6A and GF-7A certified per Mobil's product page. GM dexos1:GEN3 Licensed, plus Ford WSS-M2C961-A1, WSS-M2C962-A1, WSS-M2C972-A1, and Chrysler MS-6395 in Mobil's recommended-for-use list. Label claims 10,000-mile drain for engines over 75,000 miles — no independent UOA data cited here. Prop 65 warning applies.
What it is and how it performs
Full synthetic motor oil with a PAO Group IV base, targeted at engines past 75,000 miles. Mobil's product page confirms API SP plus ILSAC GF-6A and GF-7A certification — the current top-tier API/ILSAC spec set. The high-mileage additive package adds seal conditioners and additional detergents on top of the synthetic base. Mobil's label drain interval is 10,000 miles for engines above 75K; community UOA evidence specific to this product was not cited at the time of this review.
Who should buy this — and who should skip it
Best for 2020+ GM owners needing dexos1:GEN3 Licensed full synthetic, plus Ford and Chrysler owners whose service bulletins call out WSS-M2C961-A1, WSS-M2C962-A1, WSS-M2C972-A1, or MS-6395 — Mobil lists this oil as recommended for those applications. Consider an alternative if your OEM specifies Honda HTO-06 — that approval is not listed on Mobil's product page for this variant; cross-check against an OEM that does carry it. Skip if your engine has less than ~75,000 miles and you don't need the seal-conditioner additive package: a standard full synthetic at the same API/ILSAC spec is the more cost-effective choice.
Safety and environmental impact
The SDS classifies this oil as not hazardous under OSHA HazCom 2012 — no signal word, no H-codes at mixture level. H304 (aspiration) does not apply at the mixture level: KV40 of 63.35 mm²/s is well above the 20.5 mm²/s viscosity-exemption threshold. The SDS §16 declares a California Prop 65 warning for reproductive harm; the listed chemical is most likely a ZDDP additive variant. Used-oil skin contact carries IARC Group 1 mineral-oil-mist concern from combustion byproducts in occupational settings — minimize skin contact during drains. The SDS on file was last revised in March 2015 — 11 years old; the H-codes here reflect that revision, and the current formula's API SP / ILSAC GF-6A / GF-7A certifications postdate the SDS, so additive-package details may have changed. Used oil goes to collection — not down the drain or on the ground. AutoZone, O'Reilly, and most municipal hazardous-waste facilities accept it.
Frequently asked questions
Is Mobil 1 High Mileage 5W-30 approved for vehicles requiring GM dexos1 Gen 3?▾
Yes. Mobil's official product page lists Mobil 1 High Mileage 5W-30 as 'GM dexos1:GEN3 Licensed.' That is the current GM approval required for most 2020+ GM gasoline vehicles to maintain powertrain warranty coverage. Confirm the GM dexos1 GEN3 mark on the bottle label before using for warranty-documentation purposes.
Does it carry the Ford WSS-M2C961-A1 or Chrysler MS-6395 approval?▾
Mobil's product page lists both. Under 'Recommended for use in applications requiring,' the page includes Ford WSS-M2C960-A1, WSS-M2C961-A1, WSS-M2C962-A1, WSS-M2C970-A1, WSS-M2C971-A1, WSS-M2C972-A1, as well as Chrysler MS-13340 and MS-6395. Note 'recommended for use in applications requiring' is Mobil's recommendation language; Ford/Chrysler issue their own approval lists, so for warranty-critical use confirm against the OEM's current approved-oil bulletin.
What does API SP + ILSAC GF-6A / GF-7A mean for my engine?▾
API SP is the current top-tier API gasoline category, succeeding API SN Plus. ILSAC GF-6A adds fuel-economy and timing-chain-wear protection on top of API SP. GF-7A (released March 2025) is the successor standard and the most recent ILSAC certification as of 2026. Mobil's product page lists both GF-6A and GF-7A for this oil — current vehicles specifying either GF-6A or GF-7A are covered.
What makes the 'High Mileage' formula different from standard Mobil 1?▾
Mobil markets the High Mileage line for engines with more than 75,000 miles — the additive package includes seal conditioners targeted at swelling aged elastomer seals to reduce drip-leak rates, plus additional anti-wear and detergent treats. The SDS §3 disclosure shows a lower percentage of declared PAO base stock (5-<10%) than the Extended Performance variant (20-<30%), reflecting more of the formula going to the high-mileage additive package. It remains a full synthetic per Mobil's product positioning.
Does the 10,000-mile drain claim hold up in the real world?▾
The 10,000-mile interval is a moderate claim compared to Mobil 1 Extended Performance's 20,000-mile claim, and it sits within the range of mainstream synthetic OEM drain intervals. Community UOA data specifically for this product was not cited at the time of this review; the rubric caps drain_interval_performance at score 6 (label-aligned) without at least two independent UOA reports — that is the current score. Severe-duty driving (lots of short trips, towing, very hot or cold ambient) depletes oil life faster regardless of label claim.
