Best practices for storing a vehicle over winter?

Hi everyone, I’m planning to store my vehicle outdoors (but under cover) over the winter. The winters here are pretty harsh. I’m wondering if it’s better to keep the fuel tank full with a stabilizer or if that might cause issues with the fuel going bad. The vehicle doesn’t get driven often, so the fuel could be sitting in the tank for quite a while. Any tips on prepping the vehicle for storage?

You’re better off filling the tank completely. A full tank helps prevent condensation, which can lead to water in the fuel. If the fuel is going to sit for more than 3 months, adding a stabilizer is a good idea.

I second this. I’ve been doing this for years with my classic car and never had fuel go bad, even after 6 months.

Good to know! Do you use a specific brand of stabilizer?

Don’t forget to pump up your tires to their maximum PSI. This helps them keep their shape while the car is stationary.

Yep, and if you can, try to roll the car a few inches every couple of weeks to prevent flat spots.

If you’re not driving the car for a long time, a battery conditioner is a must. It’ll keep the battery charged and healthy over the winter.

Great suggestion. I bought one last year, and it’s been a game-changer for my stored vehicles.

For harsh winters, check the coolant concentration too. A 50/50 mix is usually good down to -18°C (0°F). You can buy a cheap tester to make sure it’s at the right level.

If the fuel might sit for longer than 6-9 months, premium gas might last a bit longer than regular. Just make sure the gas cap is tight to prevent evaporation.

Thanks! I’ll keep that in mind since it’s not driven often.
