Use one bottle per tank for most effective treatment
For the most effective treatment, it is recommended to use one bottle of Red Line Complete SI-1 Fuel System Cleaner per tank.

Following the initial treatment, the treatment quantity can be reduced to a third to a sixth of the bottle (one bottle to 50-100 gallons of petrol) for regular maintenance. This will provide continual injector and valve cleanliness.
It is worth noting that some users have reported a decrease in mileage with each tank of fuel in which the cleaner was used. However, others have reported improvements in their mileage, acceleration and idle after using the product.

Safe for use in unleaded, reformulated, and oxygenated gasolines
Red Line Synthetic Oil's SI-1 is a popular fuel system cleaner. It is safe for use in unleaded, reformulated, and oxygenated gasolines.
Unleaded gasoline is a type of petrol that does not contain lead compounds. Unleaded petrol should also not contain oxygenated compounds. By the end of the 1990s, leaded gasoline was banned within the entire European Union, except for Avgas 100LL for general aviation. The last country to deplete its reserves of leaded petrol was Algeria, and its eradication is considered an "international success story".
Reformulated gasoline is a type of fuel that contains oxygenates, which are used as fuel additives and octane enhancers. Oxygenated gasoline is another name for reformulated gasoline, and it is known as California reformulated gasoline (CARBOB) in California. The use of oxygenates in gasoline has been studied for its potential environmental impacts.
Oxygenated fuel is a type of gasoline that contains oxygen. Fuel oxygenates are used as fuel additives and octane enhancers in reformulated gasoline, oxygenated fuel, and premium grades of unleaded gasoline. Their use is decreasing, but they are still found in fuel spills and releases from underground storage tanks, which can contaminate groundwater.
Red Line's SI-1 fuel system cleaner is safe for use in all of these types of gasoline. To use it, you should add one full bottle to a nearly empty tank and then refuel up to 20 gallons of gasoline or petrol. For regular maintenance, you can use half a bottle every 1,500 miles.
