The frequency with which the spark plugs on a car need to be replaced is due to the peculiarities of car operation, its age, the choice of fuel and oils.
A spark plug is a consumable for any gasoline engine, and, as a result, requires timely replacement. In this regard, the question often arises about the frequency of this procedure.
The ideal option is to undergo technical inspection and maintenance of the car within the time frame specified by the regulations. In this case, the replacement of the candles will be done on time. However, due to a number of objective or subjective reasons, the need to put new candles may arise at any time.
When to replace candles?
There are a number of main signs that indicate the need to pay attention to the condition of the spark plugs.
1. Presence of carbon deposits on the candle.
2. Irregular engine operation.
3. Drop in engine power.
4. Increased fuel consumption.
In order for the candle to work out its entire period, it is necessary to follow a number of simple recommendations. First, refuel only with high-quality gasoline with the appropriate octane number. If possible, use only fuel of a certain manufacturer (candles "get used" to a specific gasoline, in which specific additives are used).
The spark plug does not like irregular work very much, so problems often arise on machines that are rarely used. Secondly, use branded candles recommended by the manufacturer for your car. Third, use only high quality engine oils. Do not allow the engine oil level to be too high or too low. Fourth, remember that as your vehicle ages, the frequency of replacement spark plugs will gradually increase due to natural wear on engine components.
What an old spark plug can tell you
If you are replacing the spark plugs yourself, and this is easy to do on any car (except for a Subaru brand car), then the state of the removed spark plug can tell a lot to an attentive and knowledgeable car enthusiast.
Pay attention to the carbon deposits that have formed on the electrodes.
1. The sandy color of the carbon deposits indicates the normal condition of the engine.
2. Black carbon (soot) indicates possible problems with the carburetor (gasoline overflow) or the air filter (not changed for a long time).
3. If the carbon deposit has an oily consistency, it is worth taking a closer look at the condition of the piston rings.
Thus, the condition of the spark plugs can point you to vehicle problems that need to be addressed soon.
