Bar's Products 4702 Rislone 8-in-1 Complete Fuel System Cleaner+ 16 oz

The Rislone 4702 8-in-1 Tune Up Complete Fuel System Cleaner+ is an all-in-one gasoline fuel additive that improves fuel quality by increasing cleaning ability, adding lubrication, removing contaminants, reducing spark knock, and helping to prevent fuel degradation. One 16 oz bottle replaces multiple separate products, delivering the equivalent of a full injector cleaner, upper cylinder lubricant, fuel stabilizer, dry gas treatment, and octane booster in a single pour.

Key Features:

• 8-in-1 formula combines injector cleaner, complete fuel system cleaner, upper cylinder lubricant (UCL), fuel stabilizer & conditioner, dry gas, gas treatment, and octane booster
• Cleans the entire fuel system — injectors, valves, fuel lines, intake manifold, and combustion chambers
• Boosts octane and reduces Octane Requirement Increase (ORI) by up to 2 numbers, minimizing spark knock, misfires, and emissions
• Water remover / dry gas helps prevent gas line freeze-ups in winter and removes moisture year-round
• Fuel stabilizer helps gasoline resist breakdown and improves stability during storage
• Upper cylinder lubricant (UCL) reduces friction and wear while improving fuel economy
• Helps eliminate noisy injectors, rough idle, hard starting, and hesitation
• Safe for all emissions components — will not harm catalytic converters, oxygen sensors, or EGR valves
• Works in capless fuel systems (Ford Easy Fuel, GM, Chrysler, Dodge, Cadillac, and more)

Compatibility:

• Engines: Fuel Injected (PFI), Direct Injected (DI/DIG), Gasoline Turbo Direct Injected (GTDI), Turbocharged, and Carbureted
• Fuels: Unleaded, Premium, E10, E15, E85, and all Ethanol Flex Fuel blends
• Also suitable for: Small engines, motorcycles, and marine applications (2-stroke and 4-stroke)

Dosage Guidelines (16 oz bottle):

• Car / Small to Mid-Size SUV (10–21 gal tank): Use one full bottle per full tank
• Light Truck / Large SUV (16–23 gal tank): Use one full bottle per full tank; for 24–36 gal tanks, use to approximately ½ tank
