A seemingly simple issue like a cracked or loose gas cap can throw your car’s entire system off-kilter, playing the unsuspecting culprit in diminishing your fuel economy. It’s particularly threatening to your car’s health, making it work harder, guzzling gas and money. When my own car’s check engine light illuminated. It was a challenge to determine if it was just the cap or something major.

Spark Plugs

In my years of automotive enthusiasm, I’ve learned that misfiring in the combustion chamber of your car is often due to worn spark plugs. As a crucial car part, these are responsible for igniting the spark that starts the engine. Neglecting them could lead to a fail, often after 100,000 miles, which can trigger the check engine light. Proactively replacing old spark plugs can make your car run better, preventing those pesky dashboard warnings.

Airflow Sensors

In the life cycle of a car, keeping an eye on the engine is paramount to ensure it’s in proper working order. The parts that often go unnoticed are the airflow sensors, which, if not working correctly, can lead to a spike in emissions and a drop in gas mileage. During my yearly tune-ups, I’ve learned that replacing an oxygen sensor annually can prevent the distress of seeing your car stall due to poor fuel-to-air ratio—something an inadequately maintained air filter could aggravate. It’s a misconception that the check engine light is solely for an oil change; it could very well be an expensive reminder of overlooked sensors.

Your Car Needs an Oil Change

When the check engine light in your vehicle becomes illuminated, it’s a crucial warning sign that should never be ignored. Often, this alert doesn’t just signal the need for an oil change; it can indicate that the engine oil is dirty, not enough is flowing, or both—any of which could activate the light. 

Pulling out the dipstick, I noticed the oil’s condition was worrying; dark and black in color, a clear message that the levels were too low and the quality compromised. Remembering my schedule had slipped, I made time today to address this pressing issue, because sometimes, the most fundamental maintenance can prevent the most significant problems.

Worn Spark Plugs

When your Subaru starts to decrease in power, it’s crucial to peek under the hood. Worn change spark plugs can indeed be the cause behind an illuminated check engine light; a signal your vehicle should be checked without delaying, as it may lead to further damage. Noticing this on my own dashboard, a timely inspection was key to maintaining optimal performance.

What to Do When Your Check Engine Light Comes On

When my Check Engine Light flickered on, it was a stark reminder that it could signpost more than just an oil change. Initially worried about needed repairs, I pondered if I had inadvertently left the gas cap loose—this alone can cause the light to activate. A quick tightening might have easily remedied the issue.

To ensure an accurate diagnosis, I didn’t hesitate to contact Bill Rapp Subaru for a service appointment. Their professional technicians examined my car comprehensively. Reflecting on my own schedule, I was glad I was close to Syracuse, making the trip from Liverpool and Oneida a breeze. Sometimes, the solutions we fear to be complicated are but a simple turn of a cap away.

Low Oil and Check Engine Light

Contrary to misconception, the check engine light may indeed turn on when low oil levels interfere with your vehicle’s engine performance. Seeing that dashboard icon flicker alongside the oil can symbol signifies low oil pressure, a serious cause for concern that could disable your car’s performance if not addressed immediately.

Effects of Low Oil on Engine Performance

Unseen to the eye but felt throughout the vehicle’s motion is the gradual increase in wear and tear when the engine operates with insufficient lubrication. Not only does this lead to overheating, but in severe cases, it precedes complete engine failure—a situation I’ve witnessed during my tenure as a mechanic. Quick, 10 minute oil changes seem a small price to pay compared to higher repair costs and the risk of drastically shorter component lifespans.
