Decent, but it's tough on the environment.

TL;DR A single-rated DOT 3 fluid with an SDS-documented dry boiling point above 450°F, about 49°F above the FMVSS 116 floor of 401°F. No wet boiling point is published anywhere, so post-moisture heat resistance can't be verified.
Lucas Oil 10826 is a DOT 3 brake fluid under FMVSS 116, which sets the federal floor at 401°F dry and 284°F wet. The SDS Section 9 documents a dry boiling point greater than 450°F, roughly 49°F above the DOT 3 minimum (one degree shy of the rubric's threshold for a meaningful margin). That figure is an SDS-stated floor rather than a TDS-published specific value, so the actual peak could be higher. The wet boiling point, which governs heat resistance after a year or two of moisture absorption, is not disclosed by Lucas Oil at all. Note that the SDS in use is the 2014 Version 1 from KMK Regulatory; no revision has been issued in twelve years.
Best for stock daily drivers whose owner's manual specifies DOT 3 and where the case-of-12 fits a shop or fleet use case. Skip it for vehicles that specify DOT 4 or DOT 5.1, and skip for track use or hilly towing where DOT 5.1 with documented boiling points above 600°F is right.
WARNING signal word from H320 (Cat 2B eye irritation) only, the milder of the two GHS eye-irritation tiers, and the only hazard code at mixture level. SDS Section 8 calls for eye or face protection during operations where splash is plausible, such as pressure bleeding. SDS Section 15 explicitly states "No products were found" under California Prop 65, and a CAS cross-check of all four ingredients confirms no Prop 65 substances; the product listing-level Prop 65 flag is generic shipping disclosure, not chemistry. The sweet taste of glycol-ether brake fluid attracts pets and small children; store sealed and inaccessible, and never decant. Used fluid is drain-destined: collect for hazardous-waste disposal, never pour down a drain or storm sewer.
No. The 10826 is single-rated DOT 3 only and is not certified to DOT 4. DOT 4 requires a higher minimum dry boiling point (446°F) and a higher wet boiling point (311°F) than DOT 3 (401°F dry, 284°F wet). If your owner's manual specifies DOT 4, buy a DOT 4 fluid instead.
The SDS Section 9 reports a boiling point greater than 450°F (232.22°C), about 49°F above the FMVSS 116 DOT 3 dry minimum of 401°F. That is an SDS-stated floor rather than a specific TDS-published value; Lucas Oil does not publish a separate TDS with a precise dry BP figure.
No. Lucas Oil does not publish a wet boiling point for this product on the manufacturer page, in the SDS Section 9, or on the product listing. The FMVSS 116 DOT 3 wet minimum is 284°F; without a manufacturer figure or third-party test sheet, the operationally relevant heat resistance after moisture absorption cannot be verified.
Yes by chemistry class: all glycol-ether brake fluids (DOT 3, DOT 4, DOT 5.1) work with ABS and electronic stability control. Lucas Oil does not include an explicit ABS or ESC compatibility statement on the product page or the SDS. The fluid to avoid in ABS-equipped vehicles is DOT 5 silicone-based, which this product is not.
The SDS Section 15 explicitly states 'No products were found' under California Prop 65, and a CAS-level cross-check of all four ingredients against the Prop 65 list returned no hits. The product listing flag is generic California-shipping disclosure rather than a chemistry-grounded warning for this specific formula. Three of four evidence sources (SDS Section 15, ingredient cross-check, and bottle imagery) are clear; the Amazon flag is the outlier.
Most manufacturers recommend every 2·3 years or 30,000·45,000 miles regardless of how the fluid looks. Glycol-ether brake fluids absorb moisture from the air over time, lowering the wet boiling point and reducing fade resistance. A brake fluid test strip from any auto parts store gives a more reliable answer than mileage alone.
