Uh oh, my check engine light came on. You possibly feel a sense of dread. No worries. Continue reading below to get a clue of what could be wrong.
My Check Engine Light Came On: What's Wrong?
The check engine light brightens when your auto's computer thinks there is an issue that might affect your vehicle's emissions control system.
When the light illuminates, a few diagnostic problem codes are in the vehicle's computer. These codes remain there even if the light disappears. To deal with a check engine light problem, you or your auto technician can get the codes by using a scanner and then troubleshooting to discover the issue.
Don't mistake the check engine light with the service or maintenance light. These lights brighten for expected routine services. Mileage and gas usage generate service lights. Get it analyzed by a mechanic.
What's Next: My Check Engine Light is On
Below are some typical situations:
The Check Engine Light Flashes.
If the check engine light flashes in the city but goes off on the highway, then the issue is only occurring in city driving conditions. Pay attention to whether or not your car works any differently when you see the light.
If you detect a difference, drive the car as little as possible and bring it to your mechanic. In this condition, you run the risk of your car dying. You don't want to be stuck on the side of the road, waiting for towing service.
The Check Engine Light Comes On and the Light Remains Lit.
If the check engine light is on continuously while driving with no visible issues, there is a fault in the emission control system. When this occurs, the computer that powers the emissions system will have your automobile working in a couple of lower gears. This idea is called "limp-home mode." Get your vehicle serviced immediately.
The Check Engine Light Remains On and there are Performance Issues.
This statement means that a crucial part of your emission control system has a significant issue. It typically is a component the automobile needed to function. In many instances, the car is not safe to drive at all. It can stop at any minute. It's advised to pull over to a safe spot and call emergency towing service.
Common Causes of a Check Engine Light
Numerous issues can cause your check engine light to illuminate, such as loose gas cap, bad spark plug wires, and bad oxygen sensor. Call Buffalo Roadside Assistance to identify your problem accurately.
Most folks are aware of which type of gas their vehicle requires. But not as many are knowledgeable about the difference between regular and premium gas.
Difference Between Regular and Premium Gas
One apparent difference is the price. Based on studies, premium fuel usually averages around 55 cents more per gallon than regular gas.
Switching from Premium to Regular Gas
Automobiles function best with a particular type of fuel.
A high-octane gas won't ignite swiftly. This fact explains why high-performance vehicles with high compression engines need higher octane gas. Engines that use higher octane fuel typically work more effectively. It is critical to use the right octane for your particular car. Using the correct octane level stops damage to your car's engine, helping it operate at peak performance.
If you use a lower than suggested level, the gas might combust too quickly for your engine. Additionally, a lower than recommended gas can diminish your vehicle's power and fuel economy, causing engine damage.
Using fuel with a high-octane rating than suggested, the possibility of danger lessens. The fact is that using premium gas when your vehicle operates on regular gas doesn't provide any extra advantages.
If your engine uses higher compression ratios, you will usually have to use high-octane gas. Your owner's manual tells you which gas is best for your vehicle model. You can look inside your fuel door. A sticker is there displaying your auto's fuel requirements.
If your car needs premium fuel, the sticker will say "premium unleaded fuel only" and the correct octane level.
The Longevity of Premium Gas
If your auto's manual just states to use "premium" or "premium recommended," you might want to test the various premium levels to analyze how your vehicle's performance alters. You could do this by letting your gas tank get to a quarter level and fill up with premium gas.
Jot down your gas mileage while driving with the various premium gas octanes. Test the different octane levels. You need to observe how your vehicle sounds and feels while driving. You also want to write down the acceleration rates.
To enhance your car's overall performance, drive it more proficiently. For instance, don't floor it when the light turns green. When driving long distances, go at a consistent speed.
