Tip #1

​Regular maintenance will ensure you are getting the best fuel mileage and lowest emissions from your vehicle. A+ Smog suggests following your vehicle's manufacturer suggested intervals for oil changes and tune ups.

Tip #2

If your "CHECK ENGINE" light is on,  this is an indication that your vehicle's emission control system needs to be repaired. Driving with the "CHECK ENGINE" light on can cause extensive damage to your vehicle. Often, these repairs are simple and inexpensive,  so A+ SMOG recommends getting the problem diagnosed promptly.

Tip #3

Check your tire pressure regularly and adjust as necessary. Low tire pressure can cause premature tire wear, decreased fuel mileage, and increased tail pipe emissions. Most vehicles have a label in the driver's door jamb for recommended tire pressure. A+ SMOG suggests checking and adjusting your tire pressure each time you get fuel.
