TL;DR Genuinely licensed by GM for Dexron VI (J-60172) and Ford for Mercon LV (MLV-120901) — both printed on the bottle, not marketing claims. No ZF Lifeguard or Toyota WS license. SDS classifies the mixture as Toxic to Reproduction Cat 2 (H361, WARNING); bottle carries a California Prop 65 warning.
What it is and how it performs
Two real OEM licenses cover the dominant US passenger-vehicle automatics — GM Dexron VI (J-60172) and Ford Mercon LV (MLV-120901), both printed on the bottle back label. Backward-compatible with the older Dexron III/IIIH/IIE/II family because Dexron VI supersedes those specs. "Suitable for all Toyota" and "Exceeds JASO 1-A" appear on the label but are compatibility statements, not licensed approvals. No ZF Lifeguard license. No independent VOA data located to corroborate a service-interval claim.
Who should buy this — and who should skip it
The clearest fit is owners of GM and Ford vehicles whose owner's manual specifies Dexron VI or Mercon LV — the licensed approvals are real and verifiable on the bottle.
Skip if your vehicle requires ZF LifeguardFluid 6/8/9 (most 2012+ BMW, Audi, Land Rover 8-speeds), Toyota WS, Honda DW-1, or Chrysler ATF+4 — those specs need a separately licensed fluid.
Safety and environmental impact
SDS §2 signal word is WARNING. H361 ("Suspected of damaging fertility or the unborn child") at mixture level, driven by the bis(nonylphenyl)amine antioxidant in §3. SDS §7: "Avoid exposure during pregnancy." Bottle carries the California Prop 65 warning. Spent ATF goes to a used-oil collection facility, not storm drains.
Frequently asked questions
Is Castrol Transmax Full Synthetic Multi-Vehicle actually licensed by GM and Ford, or does it just claim to meet the spec?▾
It is genuinely licensed. The bottle back label shows the GM Dexron VI license number J-60172 and the Ford Mercon LV license MLV(120901). These are real OEM-issued license numbers — not 'meets spec' or 'equivalent to' wording. That makes this product appropriate for vehicles where the owner's manual calls for Dexron VI or Mercon LV.
Why does the bottle carry a California Prop 65 warning?▾
SDS §15 lists multiple Prop 65 substances that can be present at trace levels in the petroleum base stocks (including Ethylene oxide, Benzene, Naphthalene, and Ethylbenzene) plus reproductive-toxin substances (Ethylene Glycol, Methanol, Toluene). The bottle back label carries the explicit warning 'Cancer and Reproductive Harm — www.P65Warnings.ca.gov.' The Prop 65 disclosure is independent of the H361 reproductive-toxin classification in SDS §2.
Can I use this fluid in a BMW or Audi with a ZF 8HP transmission?▾
No. This product does not hold a ZF LifeguardFluid 8 or LifeguardFluid 9 license. BMW, Audi, and Land Rover vehicles with ZF 8-speed transmissions require a fluid carrying the specific ZF approval. Use a ZF-licensed fluid for those applications and verify on ZF's approved-fluids list at zf.com.
Is it safe to use this in a Toyota that calls for Toyota WS?▾
The bottle and listing claim suitability for Toyota automatic transmissions, but this product does not hold a Toyota WS license. Toyota WS is Toyota's own published specification with an approved-fluids list; this product is not on that list. The conservative choice for a Toyota WS application is a Toyota WS-licensed fluid or genuine Toyota ATF WS. Confirm against your owner manual and Toyota's published fluid list before substituting.
What does the H361 reproductive-toxin classification mean for normal use?▾
SDS §2 classifies the mixture as Toxic to Reproduction Category 2 — 'Suspected of damaging fertility or the unborn child.' SDS §7 specifically calls out 'Avoid exposure during pregnancy.' The classification is driven by the bis(nonylphenyl)amine antioxidant in §3. For a routine drain-and-fill service performed by someone not pregnant, dermal contact during the pan-removal and pour steps is the relevant exposure pathway — nitrile gloves and skin washing after handling are the standard mitigation per SDS §8.
