Operating Principles
Techron Concentrate Plus utilizes advanced Polyether Amine (PEA) technology, which is a highly effective detergent. When added to your fuel tank, this formula mixes with the gasoline and travels through the entire fuel system.
The PEA molecules actively seek out and bond with harmful carbon deposits that accumulate on critical engine parts such as fuel injectors, intake valves, and within combustion chambers. These deposits, which can build up over time from regular fuel use, can hinder engine performance and reduce fuel efficiency.
Once bonded, the Techron formula works to break apart and remove these deposits. The loosened deposits are then safely burned off during the combustion process and expelled through the exhaust system, leaving the fuel system components clean. This cleaning action helps to restore the engine's original design efficiency, leading to improved power, acceleration, and fuel economy.
Maintenance Schedule
For best performance and to maintain a clean fuel system, it is recommended to use Chevron Techron Concentrate Plus regularly.
- Automobiles and Trucks: Use every 3,000 miles or at your next oil change, whichever comes first.
- All Other Gasoline Engines: Use as needed for motorcycles, dirt bikes, boats, ATVs, RVs, watercraft, lawn care equipment, and other gasoline-powered engines.
Always refer to your vehicle owner's manual for specific recommendations regarding fuel additives and maintenance schedules.
