(2 pack) Chevron Techron Complete Fuel System Cleaner, 10 oz

• A fuel system additive poured into your gas tank
• Designed for gasoline engines in cars and light trucks
• Works through the fuel system while you drive (not a mechanical cleaner)

It targets deposits inside:

• Fuel injectors
• Intake valves
• Combustion chambers
• Fuel system components (including minor sulfur-related buildup)

• Restores engine performance: Helps smooth out rough running engines
• Improves fuel efficiency (sometimes): Especially if deposits were affecting combustion
• Better cold starts: Can reduce hesitation in cold weather
• Reduces knocking/pinging: By cleaning combustion chamber buildup
• One-tank treatment: Works in a single full tank of fuel

• After long periods of stop-and-go driving
• If fuel economy has dropped
• For routine maintenance every few thousand miles
• When a car feels slightly sluggish but has no mechanical issues

• Not a repair product: It won’t fix mechanical problems or worn parts
• Results depend on buildup level—newer engines may notice little difference
• Works best as preventive maintenance, not emergency repair
• Overuse isn’t necessary; typically used every ~3,000 miles or occasionally

• Pour the entire 10 oz bottle into a near-empty fuel tank
• Fill up with gasoline afterward
• Drive normally so it circulates through the system
