Gold Eagle Co. STA-BIL Storage Fuel Stabilizer

Community evidence from motorcycle, small-engine, and boating forums consistently confirms reliable protection through one off-season (6-10 months). The manufacturer's 24-month claim appears on the label and product marketing, but independent multi-season corroboration is mixed; many long-term users report retreating after 12 months rather than pushing to 24. Single-season use is well-supported by the large owner base.

The label explicitly states 'Effective in all ethanol blended fuels' and community reports do not document phase separation failures in E10 pump gas. Passable for standard E10 storage up to about 6 months. The SDS does not disclose a specific ethanol stabilizer or co-solvent active, so the compatibility claim is based on label language and community evidence rather than verified ingredient chemistry.

The product is formulated for gasoline engines including small engines, carbureted equipment, fuel-injected vehicles, and marine gasoline applications. It is labeled for E10/E15 blends. Diesel compatibility is not stated on the label or in the TDS; use the diesel-specific STA-BIL formula for diesel applications.

The standard dose is 1 oz per 2.5 gallons of fuel. For a 5-gallon can, use 2 oz (approximately the 2 oz mark on the integrated measuring cup if your bottle includes one). The 16 oz bottle treats 40 gallons total.

SDS §15 explicitly states: 'This product does not contain any substances known to the state of California to cause cancer, developmental and/or reproductive harm.' The product carries a GHS carcinogenicity classification (H350) from the sweetened middle distillate fraction, but that fraction is on the GHS carcinogen list and not on the California Prop 65 list; the two lists use different evidence thresholds. Note: the Amazon listing as of 2026-06-11 displays a Prop 65 warning; that flag is a conservative self-reported label applied by the seller and contradicts the SDS §15 explicit negative. CCT scores from the SDS.
