It’s packaged for easy addition to a vehicle’s fuel tank or for use in service applications where a powerful solvent is needed to restore proper fuel delivery and combustion efficiency. The product is sold as a single 15‑ounce unit in the 4 set 0116 listing.\u003c\/p\u003e\n\n\u003ch3\u003eHow does B-12 Chemtool improve fuel system performance?\u003c\/h3\u003e\n\n\u003cp\u003eThe concentrated solvents penetrate and break apart hardened gum and varnish that accumulate from degraded gasoline. By removing those deposits, injectors and carburetor bores can return to more precise spray and flow characteristics, which supports smoother idling and consistent throttle response.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh‑energy solvent technology dissolves stuck deposits quickly.\u003c\/li\u003e\n  \u003cli\u003eHelps restore injector spray patterns and carburetor bores.\u003c\/li\u003e\n  \u003cli\u003eReduces deposit-related rough idle and hesitation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen and how should I use this cleaner?\u003c\/h3\u003e\n\n\u003cp\u003eUse Berryman B-12 as part of scheduled maintenance, after fuel system repairs, or when symptoms like rough idle or poor throttle response appear.
