Spark Plugs and Spark Plug Cables:

They should be kept with the same thermal degree indicated by the engine manufacturer; this should not be altered. They should be changed each 6,000 miles.

Fuel, oil and engine oil filters:

They should be changed for the engine safety and user comfort sake. It is recommended to make the change at the first 1,000 miles after the Full Flex Gold installation, because the oil can be contaminated with the sludge caused by gasoline. From then on, as manufacturer´s recommendations of the vehicle.

Engine:

The use of adulterated fuel is very common today, which causes large concentrations of sludge on the motor block causing losses and even the motor block locking.

In spite of the higher consumption per mile traveled, the ethanol is cleaner and does not cause this type of problem and if used in an E85 mix it will promote better lubrication of the parts in contact with the mixture and thus, will increase the engine useful life and ensure a significant increase in fuel economy.

"The engine that runs on ethanol and gasoline is more economical, ensures a long useful life due to the low contamination of oil and most importantly, is pollution free".

Fuel Pump:

Check the fuel pump pressure and flow. These items are important for the good operation of the system. These data should be in accordance and within the standards set by the vehicle manufacturer. After confirming the compliance of the data above, you may proceed with the Full Flex Gold installation.

The use of ethanol reduces the vehicle original fuel pump useful life, a serious wear can occur up to the burning of the pump. In order to avoid these problems it is recommended to use a minimum of 20% of gasoline in the vehicle. If the burning of the pump occurs, a pump for ethanol should be installed.

Injection Nozzles:

The injection nozzles should be cleaned each 6,250 miles, in view of the dirty existing in the fuels nowadays.The injection nozzles are gauged to run under the normal pressure of 3.0 bar, with 5% tolerance; a low tolerance that if not respected, can cause losses: increased consumption, poor vehicle performance, bumps while changing gears and difficulty to reach the maximum speed. For that reason we should always check the injection nozzles. It is recommended to clean the injection nozzles again, at the first 625 miles after the Full Flex Gold installation.

Polarity:

The polarity of the injection nozzles is important; some vehicle manufacturers invert the feeding, thus causing problems when you have to install some equipment. However, Full Flex Gold recognizes the polarity automatically, as well as the injection nozzle resistance and the current used, thus avoiding problems during the product installation.

Cold Starting:

The cold starting is recommended for those who want to use 100% ethanol in the vehicle and in places where the temperature is below 15ºC.

Lambda Sensor:

It should be in perfect operating condition, which means that submitted to an evaluation it should be oscillating between 50 and 950 millivolts, always bordering on minimum and maximum. It should not lock.

MAP Sensor :

Check the sensor pressure, which should be within the manufacturer’s specifications. The MAP sensor useful life is 25,000 miles; it is advisable to change it after that.
