e3 Sparkplugs Claim to Save Gas
Here’s a site that shows what an e3 sparkplug looks like and what it claims to do. I find information like this interesting. Once again some company has come along with some gadget that it claims will improve your gas mileage and all for a high cost. If spark plug design affected mileage that much the manufacturers would put these plugs into the cars when they were built.
Here’s the deal. The plug sends a spark through the compressed fuel and air mixture, lighting it up. As long as the mixture burns the plug has done its job. If the mixture is not lit you will feel the engine miss and lose power. The spark plug could have any shape, as long as it lights the fuel and does not fall apart, that’s all it has to do.
The only time different spark plugs will affect your mileage is when the old ones are fouled and are no longer lighting up the cylinder. You will want to put the proper plug into your engine. This means the plug the engine was designed to use. Using the wrong sparkplug can damage your engine. The shape of the ground lead on the plug is not going to change your mileage. The way you drive affects mileage. The design of the car affects mileage. The quality of fuel affects mileage. The spark does not propel the car forward, burning gas does that.
Gasoline is expensive these days, and the price keeps going up. If you are worried about low fuel mileage, sell your hummer and buy a nice little four cylinder car. Spending lots of cash on dubious products that claim to save you money will only get you deluded and burned.
