Service Engine Soon Light Could Mean Poor Mileage

Not all check engine lights are the same!

Some, such as the “service engine soon light,” could mean it’s time for routine maintenance…

…and it could also mean your car’s gas mileage is being affected.

Even one or two additional miles per gallon adds up over time.

That could total 12 – 24 more miles you can drive per tank of gas (or a saving of $3 or more per fill up).

Most cars require multiple scheduled maintenance services which are hardcoded in the car’s computer system to turn on the service engine soon light when they are due…

…and are documented in the vehicles owners manual.

Let’s see what you can learn before searching the net for car tune up shops near me

My service engine soon light turned on but my car feels fine, is something broke?

To answer this question let’s break it up:

  • Your code may only mean a scheduled maintenance is required.
  • And, no is doesn’t necessarily mean anything is broken.
  • I know a check engine light is scary but they are not all the same.
  • Some lights only mean it’s time for scheduled maintenance such as an engine tune-up.

Preventive Maintenance

Here’s a list of preventive maintenance most cars need (and in Phoenix heat) sometimes more often than recommended:

Mid to Major Maintenance

Note: Not all maintenance actions are listed.

Every car manufacturer has their schedule for when a certain maintenance is due and will alert you via a service engine soon light when your car’s odometer passes a certain mileage (or is listed in the owners manual).

When cars age or get high mileage, service engine soon lights for engine tune up, timing belt replacement and transmission maintenance are very important (these services should never be ignored).

Preventive maintenance could save the DIY mechanic money on a costly engine or transmission repairs and keep you from getting stranded in the Phoenix heat…

…not to mention wasting gas because your engine needs a tune-up.

Not every check engine light means there is an emergency!

As covered in this post, some dash lights are just alerting that a regularly scheduled maintenance is due. If you had a scan tool you could pull the codes to determine what was causing the light to come on.

To find out more about your cars scheduled maintenance schedule check your vehicle’s glove compartment for a manual.
