DURA LUBE Catalytic & Exhaust Treatment Fuel Additive 16 fl oz, 2-Pack — Cleans Catalysts, O2 Sensors & Injectors

Dura Lube Severe Catalytic and Exhaust Treatment is a 16 fl oz fuel-additive cleaner formulated to remove carbon and contaminant deposits from catalytic converters, oxygen sensors, and fuel injectors to help restore performance and emissions efficiency.

This concentrated pour-in treatment is built for gasoline engines that show signs of reduced power, rough idle, hesitation, or emissions-related trouble codes. It circulates through the fuel system and the exhaust path to target stubborn carbon deposits, phosphorus, and zinc contamination that can impair catalytic operation and sensor accuracy. The product is supplied as a convenient 16 fl oz solution and this listing is for a two-pack, offering two treatments for preventative maintenance or follow-up service.

How does this additive help when my vehicle feels sluggish?

The formula works as a fuel system and exhaust cleaner to reduce deposit buildup that chokes airflow and fuel spray patterns. By loosening and dissolving carbon and contaminant films, it can help restore smoother acceleration and throttle response without mechanical disassembly.

• Targets deposits on catalytic converter substrates and oxygen sensors
• Assists fuel injector cleanliness for more consistent spray patterns
• Promotes more complete combustion to reduce hesitation

Will this address a check engine light or emissions failures?

It can help resolve emissions-related codes when the root cause is buildup on the catalytic converter or oxygen sensors; cleaning these components may clear codes tied to reduced conversion efficiency. However, it does not bypass or disable emissions controls and will not act as a tuner or delete device.

• Designed to remove carbon that impairs catalytic function
• Safe for oxygen sensors—helps restore accurate readings
• Not intended to defeat, bypass, or override OBD or emission systems

How do I use Dura Lube Severe Catalytic and Exhaust Treatment?

Using the product is straightforward: pour the 16 oz treatment into a near-empty fuel tank before refueling, then fill the tank to mix the additive. For best results follow vehicle idling and driving recommendations; repeat as needed for severe buildup or as part of scheduled maintenance.

• Pour treatment into fuel tank, then refuel to ensure mixing
• One 16 oz bottle treats a full gasoline tank according to directions
• Use periodically or when symptoms like rough idle or reduced power appear

Is this compatible with my vehicle and safe to use?

Yes — the formulation is made for all gasoline engines found in cars, trucks, and SUVs. It’s a pour-in additive that won’t alter factory emission controls or act as a modification to the vehicle’s OBD system, but it should be used according to label instructions.

• Universal for gasoline engines—cars, light trucks, SUVs
• Non-tuning; does not disable emission control devices
• Convenient 16 fl oz pour-in bottle; this listing includes two bottles

Who this is for: Dura Lube Severe Catalytic and Exhaust Treatment is suited for vehicle owners and DIY mechanics who suspect emissions or exhaust flow problems, drivers experiencing loss of power or rough idle, and fleet managers looking for a preventive maintenance additive. It’s a cost-effective step to try before expensive component replacement when symptoms point to deposit-related performance loss. For persistent issues, combine this treatment with proper diagnostics and repairs as needed.

Manufacturer note: This product is not intended to bypass, defeat, or shut down emission control devices and will not override malfunction indicator lights or OBD system functions.
