How Often Should the Spark Plugs on a Trumpchi GM8 Be Replaced?
2 Answers
Trumpchi GM8 spark plugs should be replaced approximately every 60,000 kilometers. Spark plug replacement cycle: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is recommended to follow the instructions in the user manual. You can refer to the following standards for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Effects of damaged spark plugs: If the spark plugs are damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in ignition, which affects the normal operation of the vehicle. Severe erosion of the spark plug, such as scarring at the top, damage, or melted and eroded electrodes, indicates that the spark plug is damaged and should be replaced. Symptoms of damaged spark plugs in a car: Damaged spark plugs may exhibit the following symptoms: difficulty starting, low power, excessive exhaust emissions, and increased fuel consumption.
Over the years of driving the Trumpchi GM8, I've gained some insights on spark plug replacement. Typically, the recommended replacement interval for spark plugs is every 40,000 to 60,000 kilometers, depending on the type and driving habits. My car uses standard spark plugs, and when I replaced them at 50,000 km last time, the mechanic said the electrode gap had widened, resulting in poor ignition performance. After the replacement, the engine started much smoother, and there was a slight improvement in fuel efficiency. If you frequently drive in congested urban areas, spark plugs wear out faster, so it's better to check them at around 40,000 km. Delaying replacement may cause engine shaking or sluggish acceleration, affecting driving safety. It's best to refer to your owner's manual, as configurations may vary for different model years of the GM8. Don't wait too long—handling it during routine maintenance saves both hassle and money. Opt for OEM or reliable brand spark plugs; spending a few hundred bucks can prevent major repair costs.
