Electronic Ignition Conversion Fuel Savings Calculator

Electronic Ignition Conversion Savings Calculator

How many miles will you have to drive before an electronic ignition conversion kit pays for itself in fuel savings?

In the following example, let's assume that installing the ignition conversion kit increases your car's fuel efficiency by two miles per gallon. In this theoretical example, your old average fuel economy was 19 miles per gallon (mpg) and the new average fuel economy is 21 mpg. With gas at $2.00 per gallon, it doesn't take that long. (Your mileage may vary.)

(cost of ignition conversion kit) x (new mpg) x (old mpg)
-------------------------------------------------------------------- = miles before electronic ignition conversion kit pays for itself in gas savings alone *
(gas price per gallon) x (new mpg - old mpg)

($60) * (21 old mpg) * (19 new mpg)             23,940
--------------------------------------             =       ------------      =      4,788 miles = 4.78 months @ 12,000 miles per year
       ($2.50/gal) * (21 - 19 mpg)                          5

This, of course, does not take into account the additional benefits of increased power, lower emissions, quicker starting, smoother running, longer spark plug life, cleaner oil, etc.

Your fuel economy may also improve noticeably if you keep the tires inflated to the car manufacturer's specifications and change the engine's air filter regularly.

* For those of you in the rest of the world: You can substitute kilometers per liter for mpg and liters for gallons to get the number of kilometers traveled for the ignition conversion to pay for itself.
