How To Dispose of Old Gas

Running old gas through an engine can damage internal components, or worse, ruin it permanently. It’s best to always dispose of the fuel and replace it with your local gas station's finest. Gas requires specific disposal methods, however, and absolutely cannot be poured into a yard, into the street, or down any drains—won’t someone please think of the fish! 

Confused as to where you should take it? Don’t be. The experienced Guides & Gear informational team will explain exactly how to remove old gas from an automobile, what tools you’ll need, and how to get rid of it. Let’s tango.

Working with volatile and flammable gasoline can be dangerous and messy, so here’s exactly what you’ll need to ensure you don’t ingest automotive lifeblood, burn down the block, or incinerate your jeans and eyebrows.

We’re not psychic, nor are we snooping through your toolbox or garage, so here’s exactly what you’ll need to get the job done.

Organizing your tools and gear so everything is easily reachable will save precious minutes waiting for your handy-dandy child or four-legged helper to bring you the sandpaper or blowtorch. (You don't need a blowtorch for this job. Please don’t have your kid hand you a blowtorch—Ed.)

You’ll also need a flat workspace, such as a garage floor, driveway, or street parking that’s also well-ventilated. Check your local laws to make sure you’re not violating any codes when using the street because we aren’t getting your ride out of the clink.

Make sure the vehicle is in an out-of-the-way location and completely cooled down (hopefully, it hasn’t been run). Remove the gas cap, and let’s get into it!

Find a local recycling and/or toxic waste disposal facility, call for and/or read specific instructions, and drop it off at the designated area. Yes, it’s that simple, but always make sure you do so with a sealed container that is meant to hold gasoline for extended periods of time.

Here at The Drive, we’re the type of people who would buy gasoline-scented Yankee candles for our living rooms. Through countless experiences working on engines, we’ve learned what to do, and more importantly, what not to do. Here are a few tips we’ve learned along the way.

You have the questions, The Drive has the answers.

A. There is no set rule for when to replace gas, but if the fuel has been sitting for six months or longer, it’s best to eat the cost and get some fresh stuff (it’s also possible to recondition old gas, but only to a point). The best way to determine whether gas is “bad” is to inspect it. 

New gas is clear or slightly yellow. If your gas is a darker yellow, brown-tinted, or black-tinted, it needs to be replaced. Other signs of bad gas include haziness, dark particles and other dirt, noticeable liquid separation, or a higher viscosity.

A. The only expense is the cost of gas used to drive to the recycling center. Some private waste management companies, however, might charge a fee. 

A. Autozone, like most other mainstream auto parts stores, does not accept gas or coolant. It does, however, accept used oil.

A. Absolutely not! If you are caught dumping gas into the ground, you will likely get fined.

A. Exxon Mobil says, “Try mixing the vanilla extract with water and rubbing it on your hands until the mixture reduces or removes the smell. You can also use rubbing alcohol or lemon juice. Once the gasoline smell is gone, wash your hands with soap and water.”
