Decent, but it's tough on the environment.

TL;DR Ford OEM concentrate for vehicles requiring spec WSS-M97B51-A1 · the factory call for Ford, Lincoln, and Mercury owners. NOAT inhibitor chemistry (Nitrited Organic Acid Technology), ethylene glycol base. H302 (harmful if swallowed) classification applies to the EG chemistry; households with pets or children should store it secured.
Motorcraft Gold Concentrated Antifreeze VC-7-B is Ford's NOAT (Nitrited Organic Acid Technology) coolant concentrate meeting Ford specification WSS-M97B51-A1, required by many Ford, Lincoln, and Mercury gasoline and diesel engines. NOAT chemistry is confirmed from SDS §3 (sodium nitrite at 0.1-1%), an extended-life inhibitor suited to Ford's engine metallurgy. Meets ASTM D3306. Sold as full-strength concentrate requiring dilution with distilled water (typically 50/50). Ethylene glycol base · SDS carries a DANGER signal word driven by H370 and H372 (target organ toxicity), a step above typical H302-only EG coolants.
Best for Ford, Lincoln, and Mercury owners whose owner's manual specifies Ford spec WSS-M97B51-A1. Strong choice for anyone who wants the OEM coolant by name at a competitive online price. Skip for vehicles requiring a different Ford spec · the label explicitly prohibits mixing with WSS-M97B44-D, ESE-M97B44-A, or WSS-M97B55-A formulations.
SDS signal word is DANGER, driven by H370 (specific target organ toxicity, single exposure) and H372 (repeated exposure · CNS, kidneys, heart, blood). H302 (harmful if swallowed) applies; ethylene glycol is acutely toxic to pets · store it secured. California Prop 65 warning is in effect. Spent coolant must be collected for recycling · most auto parts stores accept used fluid. H412 applies; do not drain to ground or storm sewer.
