Volvo recommends that spark plugs be changed every 30,000-75,000 miles depending on the spark plug type. However, if you drive in stop-and-go traffic or in other adverse conditions, it is best to change them more often.
Types of Spark Plugs
Spark plugs come in different types, and each type has its own advantages and disadvantages. The three most common types of spark plugs are:
Platinum spark plugs
Iridium spark plugs
Copper spark plugs
Platinum and iridium spark plugs are more expensive than copper spark plugs, but they last longer. Platinum spark plugs can last up to 60,000 miles, while iridium spark plugs can last up to 100,000 miles.
Copper spark plugs are the least expensive type of spark plug, but they need to be replaced more often. Copper spark plugs should be changed every 20,000-30,000 miles.
The best way to decide which type of spark plug is right for your Volvo XC90 is to consult your owner’s manual or ask a certified Volvo technician.
What Are the Symptoms of Bad Spark Plugs?
If you think your Volvo XC90’s spark plugs may be going bad, there are a few symptoms to look out for:
Your car is hard to start.
The engine is misfiring.
You’re getting poor fuel economy.
If you notice any of these symptoms, it’s best to take your car to a certified Volvo technician and have the spark plugs checked.
Do Spark Plugs Wear Out?
Yes, spark plugs do wear out over time. Even the best quality spark plugs will eventually need to be replaced.
