TL;DR Ford's genuine OEM ATF-type power steering fluid for Ford, Lincoln, and Mercury vehicles specifying MERCON V or MERCON. The reference formulation, not an aftermarket match. Prop 65 warning applies.
Ford's own MERCON V fluid (license M5091101) for power steering and automatic transmission service on Ford, Lincoln, and Mercury platforms. Hydrotreated petroleum base oil with a viscosity index of 205 for strong cold-flow and high-temp stability, plus an additive package covering wear protection, oxidation resistance, and corrosion inhibition. Well-regarded by owners, who confirm direct-fit compatibility with no pump noise.
For any Ford, Lincoln, or Mercury owner whose service manual specifies MERCON V or MERCON for the power steering reservoir or automatic transmission. Skip it for applications calling for MERCON SP, MERCON LV, FNR5, or Type-F · these are distinct, incompatible specs. Skip for European and Japanese platforms requiring their own OEM hydraulic fluids. Skip if your vehicle has electric power steering (EPS) · EPS systems do not use hydraulic fluid.
The SDS classifies this product as NOT CLASSIFIED under GHS · no signal word, no H-codes at the mixture level, HMIS Health = 0. The SDS explicitly states no aspiration hazard. A Prop 65 warning is on the bottle label; the triggering substance is not disclosed. Drain-destined: collect old fluid during a flush and take it to an automotive fluid recycler.
Ford, Lincoln, and Mercury vehicles whose owner's manual or service documentation specifies MERCON V or MERCON type fluid. Common applications include Ford rack-and-pinion power steering systems on models from the late 1990s through the mid-2010s. Always verify with your owner's manual · MERCON V is not the correct fluid for vehicles specifying MERCON SP, MERCON LV, or electric power steering.
No. The product label explicitly states: 'Do not use in transfer cases where MERCON ATF was previously recommended.' Transfer case applications require a specific fluid · check your owner's manual for the correct specification.
No. These are distinct specifications with different additive packages and viscosity profiles. MERCON V must not be used in applications specifying MERCON SP or MERCON LV. Substituting the wrong MERCON variant can damage clutch packs in automatic transmissions that specify a different spec.
Aftermarket ATF formulations licensed for MERCON V (look for the Ford license number on the label) are generally acceptable. Ford's own XT-5-QMC is the reference formulation the spec was designed around. If using an aftermarket product, confirm it carries a valid MERCON V license number · 'meets or exceeds MERCON V' without a license number is a marketing claim, not a certification.
