How long can the original spark plugs last?
2 Answers
The service life of original spark plugs varies under different conditions: 1. Nickel alloy spark plugs have a service life of about 20,000 kilometers; 2. Platinum alloy spark plugs have a service life of about 40,000 kilometers; 3. Iridium spark plugs have a service life of about 60,000 to 80,000 kilometers. The service life of spark plugs is related to factors such as electrode material and spark plug brand. To maintain spark plugs, it is necessary to perform regular inspections, timely replacements, and periodic cleaning. When carbon deposits are found on spark plugs, they can be soaked in kerosene for a period of time and gently scrubbed with a fine steel brush. After removing the carbon deposits, dry them with compressed air before reuse.
I've driven many cars, and experience tells me how long the original spark plugs last depends on the material. Copper spark plugs are the cheapest but have the shortest lifespan, typically just 20,000-30,000 kilometers, wearing out faster with frequent city traffic jams. Platinum ones are slightly better, lasting 40,000-50,000 kilometers without issues. Iridium plugs are more advanced and can go 80,000-100,000 kilometers—my old car's lasted 100,000 before replacement. Don't just focus on mileage; consider driving habits too: frequent highway driving can extend their life, but stop-and-go traffic means earlier checks. If you notice delayed ignition or reduced power, replace the spark plugs immediately—delaying could increase fuel consumption or even damage the engine. During regular maintenance, ask the mechanic; they can assess based on carbon buildup. In short, saving on this small expense isn't worth it—early maintenance ensures safety.
