Is the car economizer easy to use? Seek an answer

Now that the oil price is high, some friends who drive want to save some oil costs, so they will naturally consider fuel economy. There are more economizer products on the market than you can count. What percentage can each product claim to save fuel? It is ok to fill in some test figures, and increase the credibility by obtaining some certificate test reports, so that consumers can understand and judge the real functions of the products themselves. The seller's things are there, and you are not forced to buy them. There are many types of oil economizer, some of which are deceptive. You should know clearly when you buy it, and don't be confused by the product description. Here, I personally express my views on the oil economizer: 1 All oil economizers themselves cannot achieve the function of saving oil. The economizer must be able to improve the engine power in an all-round way. The capacity of products that can generate energy (electric energy) or store energy (electric energy) should not be too small, because there are many places to strengthen electricity. For example: spark plugs, ignition systems, oil supply systems, air-conditioning compressors, headlights, etc .. 4 To save fuel, it is necessary to control the throttle (if the horsepower is increased, the throttle will naturally be less (lighter)) 5 If you add an economizer, your driving habits will be better, because if you have high horsepower, you will step on the throttle indiscriminately and consume more fuel. Many consumers who buy economizer think that installing economizer can save fuel, which is wrong.
