It combines detergents and lubricants to help restore throttle response and improve combustion efficiency without requiring disassembly. Sold as a 12-pack, each 5.25-ounce bottle treats multiple tanks depending on the application, making it a practical option for home use, fleet maintenance, and professional shops.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this product improve engine performance?\u003c\/h3\u003e\n\u003cp\u003eThe Lucas Oil formula removes deposits that restrict injector spray patterns and choke intake pathways, helping fuel to atomize more evenly. Better atomization supports more complete combustion, which can improve throttle response and reduce rough idling.

That protective film can be especially helpful when using low-sulfur or ethanol-blended fuels that may offer less inherent lubrication. Regular maintenance applications help keep parts moving freely and can extend component life.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdds lubrication to internal fuel system components\u003c\/li\u003e\n  \u003cli\u003eNeutralizes some low-sulfur fuel issues by supplementing lubrication\u003c\/li\u003e\n  \u003cli\u003eDesigned for routine preventive use to minimize wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I use the 5.25 oz bottle for best results?\u003c\/h3\u003e\n\u003cp\u003eEach small bottle is formulated to be poured directly into a full tank of gasoline as a treatment dose. Follow the label dosage instructions for tank sizes and repeat intervals; typically one bottle treats a tank, but heavy deposits may need multiple treatments spaced over tank fill-ups. Run the engine for a short drive after adding the treatment to circulate the formula through the system.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePour entire 5.25 oz bottle into a full gas tank as directed\u003c\/li\u003e\n  \u003cli\u003eDrive normally to allow formula to pass through injectors and combustion chamber\u003c\/li\u003e\n  \u003cli\u003eRepeat per label guidance for stubborn deposits or preventive maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat practical benefits can I expect after treatment?\u003c\/h3\u003e\n\u003cp\u003eUsers typically notice smoother idle, crisper throttle response and reduced engine knock related to deposits, though measurable fuel economy gains depend on vehicle and driving habits. The cleaner spray pattern and lubricated internals help combustion run closer to factory design, which may lower some emissions and improve driveability. Keep realistic expectations: severe mechanical issues or clogged fuel filters require professional repair.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eImproved idle smoothness and throttle feel for many vehicles\u003c\/li\u003e\n  \u003cli\u003ePotential for modest MPG improvement after deposits are removed\u003c\/li\u003e\n  \u003cli\u003eReduced deposit-related hesitation and misfire risk in some cases\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Lucas Oil Fuel Injector Cleaner 5.25 oz (pack of 12) suits vehicle owners, small fleets, and service technicians who want a convenient, concentrated injector and upper-cylinder cleaner that doubles as a lubricant. It’s ideal for routine fuel-system maintenance, seasonal tune-ups, or as part of a preventive program to protect pumps and injectors—especially for vehicles that run ethanol blends or low-sulfur fuels. Not a substitute for mechanical repair; for persistent drivability problems consult a technician.\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: How often should I use one 5.25 oz bottle?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Add one bottle per full tank as needed; repeat every 3,000–5,000 miles for preventive maintenance or sooner for heavy deposits.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this safe for modern fuel-injected engines?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, the formula is designed for gasoline fuel-injected systems and contains detergents and lubricants compatible with common materials.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Lucas Oil","offers":[{"title":"Default Title","offer_id":48081034215582,"sku":"B0167BASDY","price":84.12,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/lucas-oil-fuel-injectr-clnr-front-packaging.jpg?v=1785795133","url":"https:\/\/northtrailauto.ca\/products\/lucas-oil-fuel-injector-cleaner-5-25-oz-12-pack-concentrated-formula-restores-throttle-response-cleans-deposits","provider":"North Trail Auto","version":"1.0","type":"link"}
