Top 5 Tips for Winter Car Storage

dusterWhen storing any car, it’s important to take into account what your specific car needs. Depending on your local climate, the condition of your car, and your available options, winter car storage can take many different shapes. Here are my recommendations and what I consider best practices when it comes to getting your car winter storage ready.

  1. Building Selection

Indoor vehicle storage with a dry, concrete floor is best for winter car storage. Try and stay away from any building with a dirt floor as the moisture will wreak havoc and can cause significant rust issues. If you don’t have a garage, most storage facilities have single car storage spaces that you can rent to store your car. The money spent is worth the peace of mind knowing it’s safe and out of the weather.

  1. Tire Care

Tire CareWhile the car is in winter storage, inflate to the max PSI on the sidewall to prevent flat spotting from sitting. On softer radials, retro bias and drag slicks may be a good idea to put the car up on jack stands. The low pressure and soft rubber will likely flat spot and ruin the tires. I also like to apply a good rubber protectant all over the tires to prevent cracking and dry rot. Also, do not leave your emergency brake on.  Leaving the brake on for an entire winter storage season can make the e- brake become one with the brake rotor. Whether you have an automatic or manual transmission — use blocks of wood behind the tires.

  1. Battery Maintenance

You have a couple of options here for battery maintenance throughout winter car storage season.  You can take the battery out of the vehicle and charge periodically to keep fresh. Keep in mind that charging the battery gives off hydrogen gas so keeping the battery in the garage is best. Or, you can leave it in the car. However, you should use a good battery maintainer trickle charger and keep it charged through the cold winter so it has plenty of power to fire the car up come spring.

  1. Interior and Exterior Cleaning

Clay bar the paint to get rid of all the contaminants that could cause problems from sitting and not having your regular washing and detailing. Clean and vacuum the interior making sure all the trash and any crumbs are gone so not to attract any unwanted visitors inside. Make sure windows are closed and place dryer sheets in the interior and in the trunk (most pests don’t not like the smell and will stay out). Seal off the exhaust to prevent rodents from crawling in and making a home. Spread a few mothballs around the perimeter of the car to keep them out and stop them from destroying your car’s interior or electrical system. Polish and wax the exterior and use a good quality, SOFT, breathable car cover to protect it and keep it as dust free as possible.

  1. Stabilizing Fuel

Don’t drain your car’s gas tank during winter storage! Instead, use a fuel stabilizer. I choose STA-BIL as it will keep gas fresh for up to 24 months. Doing this will also prevent gum, varnish, and corrosion from forming.

Following these simple tips will get you through the long storage months and ease your mind until it’s time to get back on the road!

  • Really nice and useful article as it addresses the difficulties faced by a person during the winter car storage and I completely agree that the battery of the car should be disconnected from the electrical system prior to storing it. Besides, the condition of different components of the vehicle should be subjected to an inspection and the inspection should be done by experienced professionals to spot and fix the mechanically abnormal components. Besides, a car needs to be properly washed prior to the storage.

  • Do you really need to put fuel stabilizer if it’s less then 6 month ?

    • Hi. Yes, it is actually recommended to stabilize your fuel as soon as it is pumped. This will ensure that you keep the fuel as fresh as possible during storage and/or infrequent use. Typically, fuel starts to oxidize (go stale) in as little as 30 days. If the 6 month-old fuel cannot be utilized or drained as soon as possible, then adding STA-BIL® at this point will help in keeping it from deteriorating any further. Hope this helps. If there are any questions, please do not hesitate to contact us at Thanks for the question!

  • I put too much Stabil in my rv van and used the generator for 5 -7 minutes. Will adding about 7 oz too much ruin my engine and generator?

    • Hello, thank you for your message. No, overtreatment with STA-BIL will not damage your engine / generator. However, we do recommend sticking to the proper dose of 1 oz. per 2.5 gallons of fuel.

      • Your reply has been very helpful and relieved my anxiety about thinking I ruined my engine & generator. Thanks

  • Hi Dale, the information was really helpful for me. However you never mentioned the possibility of rodent attacks while storing the car long during winter. Can you recommend on how to avoid it?. Thanks!
