Its use can maximize fuel economy and restore lost power, performance and acceleration. TECHRON CFSC is formulated with a proprietary combination of polyetheramine (PEA) that works in one tankful to remove deposits that can cause a loss of power, hesitation, knocking & pinging and higher exhaust emissions. Regular use can help prevent harmful sulfur components in gasoline from attacking sensitive electronic fuel sending units on some vehicles. Also, by cleaning combustion chamber deposits, it can relieve cold start problems and minimize deposit-related knock and ping. TECHRON CFSC is fully compatible and protective in all commercially available ethanol blends (E10, E15, E85, etc.). TECHRON CFSC is designed for all gasoline engines including carbureted, two-stroke, four stroke, port fuel injected and direct injected engines. Not for Aviation. To keep the entire fuel system clean, use TECHRON CFSC every 3,000 miles or at scheduled oil change intervals. Will not harm catalytic converters and oxygen sensors. Not recommended for diesel engines. - Cleans, restores, protects the entire fuel system (fuel injectors, carburetors, intake valves and combustion chambers) - Minimize smog producing emissions - Restores lost power and performance - Restores and protects operation of the fuel gauge sensor - Suitable for use with catalytic converters - Backed by the Chevron brand ## Specifications | Specification | Value | | --------------------------------- | -------------------- | | Brand | Chevron | | Container Size | 12 fl oz (US) | | Volatile Organic Compound (VOC) | 0 VOC | | Removes Water | No | | [Fuel Additive](https://www.napaonline.com/en/shop/oil-chemicals/fuel-engine-additives/fuel-additives/fuel-additive/349629033) Style Name | Techron Fuel Additive | | Treats Number of Gallons | .09 | | Volatile Organic Compound (VOC) | 66.9% weight | | Manufacturer Part Number | 66740 | | Sub Brand | Techron | | VMRS Code | 053999002 | | SDS Required | Yes | | Catalytic Converter Safe | Yes | ## Safety Information - [MSDS - Techron Concentrate Plus](https://assets.genpt.com/pdf/id/1792848) - [California Prop 65 - WARNING: California Proposition 65 - Cancer and Reproductive Harm - www.P65Warnings.ca.gov.](https://assets.genpt.com/pdf/id/98629219) ## Vehicle Fitment Guide We're sorry, there is no Buyers Guide available for this item. ## Product Reviews
