Fuel Saving Tips
Most folks are unaware that a cars ignition coil can lose as much as 50% of its power in the first 3-5 years of use. If you have a vehicle with a single coil (as opposed to a car with individual coils for each cylinder) that’s over 3 yrs. old consider replacing it with a new OEM coil or a “high energy” type coil, you may realize as much as a 3 to 5 MPG increase BTW, if you replace your coil with a “high energy” type coil you will probably need to re-gap your spark plugs as well for optimum results.
