Q1: What Do Spark Plugs Do?
A1: Spark plugs, as the name implies, are little metallic pieces that provide the initial spark that starts the engine's combustion process. You need functional spark plugs to start your Mercedes Benz. A healthy set of spark plugs are necessary to keep the motor running correctly and efficiently. Still, over time, unburnt gas and oil can lead to an accumulation of rubble and residue that will make it more troublesome to start your vehicle. When this happens, you should replace them as soon as possible.
Q2: When Should You Replace Spark Plugs?
A2: Keeping up with your vehicle's maintenance is not as hard as you think. Spark plugs are a vital part of your vehicle maintenance, even though it is not done as often as your oil changes and tire rotations. Generally speaking, spark plugs will usually last for 100,000 to 120,000 miles. However, you can also check your Mercedes Benz's owner's manual for an exact interval number.
Q3: What Are the Signs of Old or Aging Spark Plugs?
A3: You can wait it out until your Mercedes Benz reaches the 100,000 to 120,000-mile mark with the set of spark plugs you have, but not all spark plugs will last that long. It's better to have them swapped out when you start to pick up on the warning signs than to wait it out and face costly engine damage down the line. Some of the most common symptoms of aging spark plugs are:
- Rough engine idling
- Difficulty starting the car after it has been off for awhile
- Engine misfiring
- Engine surge or lag
- Poor fuel efficiency
- Poor acceleration
Q4: What Are the Different Types of Spark Plugs?
A4: There are copper, platinum, double platinum,and iridium spark plugs. While there is an endless range of spark plugs available on the market today, the manufacturer will always recommend a particular design that delivers the right performance for your engine. You should always follow the recommendation to ensure you get the best air/fuel mixture and optimal fuel economy.
