6 Tips to Help Your Car Pass an Emissions Test
Many states, like Maine, require annual vehicle emissions tests (i.e. smog tests). Here are some tips for preparing your car to successfully pass this yearly checkup, whether you live in The Pine Tree State or in another part of the U.S. that requires this evaluation.

Smart strategies for success
1. Regular maintenance
For starters, make sure that your vehicle is up to date on maintenance. It is especially important to keep up with oil changes since old, dirty oil can impede how your car performs on the smog test, according to CARFAX’s Warren Clark.
2. Fuel additives
Regularly use a fuel additive to help lower your vehicle’s emissions when you’re driving it. They work by removing carbon deposits that accumulate in the engine. Every now and then, pour the additive into the fuel tank before you pump gas.
3. Drive more
Racking up miles on the odometer can be a good thing when it comes to the time leading up to your car’s smog test. Clark advises putting at least 100-200 miles on your vehicle after you’ve changed the battery or had another service task done. That’s because mechanics disconnect the battery for a short period when replacing it or performing certain maintenance items. This wipes your vehicle’s memory chip and having a populated memory chip is crucial for doing well on the emissions test.
4. Check your engine
Ensure that the check engine light isn’t illuminated on your vehicle’s dashboard. If this symbol is turned on during the test, you’ll automatically fail to pass it, as Clark confirms.
It’s also a good idea to make sure that your car’s tires are at the proper inflation level before the day of your test. This will enhance your vehicle’s stability on the machine that the testing site uses.
6. Warm it up
And spend some time driving your car right before the smog test. Engines that are warmer have a better chance of acing the test than those that are cooler.
