|"All inline units are installed in the fuel line after fuel filter. Unit can be simply mounted anywhere in the engine compartment, away from excessive heat and vibration."
After fitting Economax in any vehicle, the immediate changes can be seen as reduction in engine sound and improvement in pickup. If a car is using Hi-Octane fuel, it can easily switch over to lower grade fuel without any compromise in performance.
For conversion to unleaded fuel use atleast two full tanks of normal leaded fuel before switching. But if leaded fuel is not available, allow 1000kms for the catalyst to adjust to lower octane fuel.
After 1200km-1500km engine oil and oil filter must be changed because all the carbon, waxes and gum deposits are cleaned and dropped in oil, which becomes dirty and clogs the oil filter. After the initial oil change the vehicle will not require oil change for longer periods and in petrol engine the spark plugs will remain cleaner for longer period.
NEW DROP-IN TANK Unit Application
Economax Drop-in-tank units are simple and easy to fit in any vehicle or engine with any capacity of fuel tank. There is no hassle of in-fuel line installation and benefits are almost the same as inline units. Please read before using the in-tank units with your vehicle or engine.
Installation of Drop Intanks.
Remove filler assembly hose located at the connection of the fuel tank. Often times the siphon block is built into the filler assembly hose, and can be bypassed by disconnecting the hose and dropping the units directly into the fuel tank. (Siphon block may exist within the tank itself).
Method No. 2
Locate fuel gauge/fuel pump/sending unit cover often located under the rear seat or cargo area. Unbolt cover, lift only 3” to access fuel tank directly.
ON-BOARD COMPUTER FUEL AVERAGE
It is very important to avoid a common pitfall while comparing pre and post Economax fuel consumption readings of a vehicle equipped with onboard computer which automatically calculates average miles per gallon or liter. The onboard computer relies on historical data to calculate average fuel consumption unless it is reset. There are two ways to reset. Most computers easily reset by buttons present on display panel on a vehicle, while others with lesser options need battery disconnection and shorting of disconnected battery lead as explained earlier.
If computer is not reset while testing for post installation fuel consumption the result will be incorrect. For example a car with a mileage of 97,000 kms with an average fuel consumption of 8kms/liters would have consumed a total of 12,125 liters of fuel. After installation and after completion of break in period of the catalyst the improvement in mileage is assumed to be 10% which means a new average of 8.8kms/liter, and we assume a driving of 3000kms after installation, so the fuel used would be 341 liters (3000kms/8.8). Since computer is not reset, it will simply add 3000kms to 97,000kms, making a total mileage of 100,000kms and similarly add fuel 12,125 + 341 totaling 12,466 liters and calculate and average consumption of 8.02kms/liter. This is the common mistake which must be avoided.
It is strongly recommended to reset the computer while checking for improvement in fuel consumption and a physical pre and post installation test is carried out simultaneously. Physical test is simple, just fill the fuel tank to full, rest trip meter to zero and drive till low fuel light comes up, note mileage on trip. After 3000kms break in period, repeat the same and you will get difference in fuel consumption on same amount of full fuel. Alternatively, after filling fuel tank to full level drive for 100kms and note mileage on trip meter and then refill again to full and note liters. Repeat after 3000kms of catalyst installation.
