If you own a Subaru car, you know that it’s a reliable and sturdy vehicle that can take you on any adventure with ease. However, to keep your Subaru in top shape, it’s essential to perform regular maintenance, including replacing spark plugs. But did you know that adding a drop of IL (iridium lubricant) on new spark plugs can have several benefits? In this article, we’ll explore the advantages of using IL on new spark plugs in a Subaru car and provide helpful tips on how to do it correctly.
Benefits of Using IL on New Spark Plugs
Improved Fuel Efficiency: Using IL on new spark plugs can help your Subaru car burn fuel more efficiently, leading to better gas mileage and lower fuel costs.
Smoother Engine Performance: IL can improve the performance of your car’s engine by reducing friction between the spark plug and the cylinder head. As a result, your engine will run smoother, feel more responsive, and perform better overall.
Longer-Lasting Spark Plugs: By using IL on new spark plugs, you can extend their lifespan by reducing wear and tear caused by the high temperatures and pressures in the engine.
How to Put IL on New Spark Plugs
Putting IL on new spark plugs is a simple process that can be done in a few steps.
Step 1: Remove the old spark plugs from your Subaru car.
Step 2: Clean the area around the spark plug holes with a clean cloth or compressed air to avoid debris getting into the engine.
Step 3: Apply a small drop of IL to the threads or the electrode of the new spark plug.
Step 4: Insert the new spark plugs into the spark plug holes and tighten them to the manufacturer’s recommended torque using a torque wrench.
How Often to Use IL
It’s recommended to use IL on new spark plugs every time you replace them in your Subaru car. In general, spark plugs should be replaced every 30,000-60,000 miles, depending on the type of spark plugs and your driving conditions. Proper maintenance can help ensure your car’s spark plugs last as long as possible.
Precautions to Take When Using IL
While IL can provide several benefits to your Subaru car, there are some precautions to take when using it. Firstly, it’s essential to use the right amount of IL – too much can cause fouling and decrease performance. Secondly, avoid getting IL on the porcelain insulator as this can cause misfiring. Lastly, it’s important to use a reputable brand of IL that is compatible with your Subaru car’s engine.
Q. What is IL, and how does it work on spark plugs?
A. IL (iridium lubricant) is a specially formulated lubricant that can be used to reduce friction between the spark plug and the cylinder head in your car’s engine. It works by forming a barrier that reduces wear and tear on the spark plugs, enabling them to last longer and perform better.
Q. Can I use IL on old spark plugs?
A. No, it’s not recommended to use IL on old spark plugs. If you do, it can cause fouling, misfiring, and decrease performance. IL is intended for use on new spark plugs only.
Q. How do I know when to replace the spark plugs in my Subaru car?
A. The recommended interval for replacing spark plugs in a Subaru car is every 30,000-60,000 miles, depending on the type of spark plugs and your driving conditions. However, it’s essential to check your owner’s manual for the manufacturer’s specific recommendations for your car.
Using IL on new spark plugs is an easy and inexpensive way to improve the performance of your Subaru car’s engine, increase fuel efficiency, and extend the lifespan of your spark plugs. By following the steps outlined in this article, you can ensure that your Subaru car stays in top shape for many years to come. Remember to always use high-quality, reputable brands of IL that are compatible with your car’s engine and consult with a professional if you have any concerns.
