Description
Molecure™ Catalytic Restore Emission Treatment — 12 oz
Keep your emissions system cleaner and your engine feeling responsive with AGS Molecure™ CR12 Catalytic Restore Emission Treatment. This concentrated fuel additive helps dissolve deposit-related buildup that can affect catalytic converters, oxygen sensors, and upstream components—issues that often show up as sluggish acceleration, rising fuel consumption, or elevated hydrocarbons.
Catalytic Restore Emission Treatment is formulated for today’s gasoline and hybrid powertrains, including port-fuel, direct-injection (GDI), turbocharged, and start-stop systems. Use it ahead of routine inspections as part of regular maintenance, or whenever you notice drivability changes. Each 12 oz bottle treats up to 20 gallons of fuel; simply add to a near-empty tank and fill up. For ongoing cleanliness and performance support, dose about every 3,000 miles.
Molecure Catalytic Restore Emission Treatment is designed to address deposit-related performance and emissions issues. It may help with conditions associated with OBD-II code P0420 (catalyst efficiency below threshold) when deposits are the cause. If warning lights persist, have the vehicle inspected to rule out sensor faults, exhaust leaks, or physical catalyst damage. Not for diesel engines.
