Designed for gasoline and ethanol-blend fuels, including vehicles with direct injection or port injection, the formula dissolves sludge and varnish so engines burn cleaner. It’s intended for routine maintenance or a targeted pre-test service to improve the chances of passing an emissions inspection while also helping restore throttle response and fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cleaner affect my emissions test results?\u003c\/h3\u003e\n\u003cp\u003eThe cleaner targets the sources of incomplete combustion—clogged injectors, restricted intake passages, and carboned combustion chambers—so the engine can run closer to factory specifications. By removing deposits that cause rich-running conditions and misfires, exhaust readings often improve after a proper treatment and driving cycle.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDetergent chemistry softens and dissolves carbon and varnish.\u003c\/li\u003e\n  \u003cli\u003eWorks in both direct-injection (GDI) and port-injection systems.\u003c\/li\u003e\n  \u003cli\u003eSingle 12 oz dose treats a full tank for most passenger vehicles.\u003c\/li\u003e\n  \u003cli\u003eHelps reduce hydrocarbons and other emissions contributors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen and how should I use the 12 oz bottle for best results?\u003c\/h3\u003e\n\u003cp\u003ePour the entire 12 oz bottle into a nearly full fuel tank before driving a normal route to allow the cleaner to circulate through the full fuel system. For best effect, drive for at least 20–30 minutes at varied speeds after treatment to let the detergent reach injectors and combustion chambers and burn off loosened deposits.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdd to fuel tank prior to filling or with a nearly full tank for correct dilution.\u003c\/li\u003e\n  \u003cli\u003eRun the vehicle under real-world driving conditions for best circulation.\u003c\/li\u003e\n  \u003cli\u003eOne treatment is typically enough for routine maintenance or pre-test preparation.\u003c\/li\u003e\n  \u003cli\u003eSafe for turbocharged engines and hybrids that use gasoline.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it harm my engine, fuel system, or emissions components?\u003c\/h3\u003e\n\u003cp\u003eCRC formulated this additive to be safe for all gasoline engines when used as directed, including those with turbochargers, superchargers, GDI, and PI systems.

CRC Guaranteed to Pass Emissions System Cleaner is aimed at drivers who want to reduce tailpipe emissions, restore smoother idling and throttle response, and improve fuel economy by removing carbon and fuel-system deposits. It's useful for people preparing for a smog test, technicians performing routine maintenance, and owners of gasoline vehicles—cars, SUVs, trucks, and hybrids—seeking a simple, one-bottle service solution.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this in a direct-injection engine?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
