Is It Safe to Leave Peanut Oil in the Car During Summer?

[SanNevaeh]

Leaving peanut oil in the car during summer is relatively safe, but it should not be stored for extended periods. Key precautions for cars in high summer temperatures include: regularly checking tire pressure, avoiding leaving gas lighters in the car, refraining from driving in sandals or high heels, and not running the air conditioning for prolonged periods. Regularly check car tire pressure: According to data from the traffic management department of the Ministry of Public Security, 70% to 80% of accidents on highways in China are caused by tire pressure issues, with 46% resulting from tire blowouts. Major traffic accidents caused by blowouts account for 35% of the total. Among blowout incidents, 20% are due to excessive tire pressure, while 57% are caused by insufficient pressure. Therefore, it is crucial to frequently check your car's tire pressure. Avoid placing gas lighters in the car: Disposable gas lighters contain plastic containers filled with liquid gas. When temperatures exceed 40 degrees Celsius, the gas inside expands due to heat, which can cause the plastic casing to explode. Do not drive in sandals or high heels: If an emergency occurs while driving in sandals, the sandals may slip off when pressing the accelerator or brake, potentially delaying braking response and leading to an accident. Avoid prolonged use of air conditioning: When the engine idles, gasoline combustion is incomplete, producing carbon monoxide. Simultaneously, passengers exhale large amounts of carbon dioxide, rapidly depleting oxygen levels inside the car. Adjust the air conditioning settings appropriately or open the windows periodically for ventilation.

I think it's not very safe to leave peanut oil in the car during summer, because when the car is parked under the sun, the temperature can soar above 60 degrees Celsius. The oil exposed to high temperatures is prone to oxidation and spoilage, developing a sour or strange taste, rendering it completely unusable. What's worse, the oil bottle might expand and crack due to the heat, causing leaks that dirty the trunk with stains that are hard to clean. It also increases the risk of fire, especially if the car's wiring is aged or the oil leaks near the engine. I suggest not storing it for long periods; after short-distance transport, take it home quickly and store it in a cool place to avoid wasting money and ensure safety. For daily storage, choose the refrigerator or a dark corner in the cupboard where the temperature is stable to prevent accidents. Paying attention to these details during summer can prevent small issues from turning into big problems. Remember, the car interior is not a storage room.

That summer, I took the lazy way out and left the peanut oil in the trunk for a few days during a heatwave. As a result, when I cooked with it, the rancid smell was unbearable, and I had to throw it all away. The car was as hot as an oven, causing the oil to spoil prematurely and wasting my money. Later, I realized that heat accelerates oil spoilage and bacterial growth, which can lead to food poisoning—totally unsafe. It was a hard lesson. Now I understand that storing oil carelessly is a no-go. Short trips are fine, but don’t leave it in the car for long, especially in hot weather. Choose a cooler spot like a shaded area in the garage or store it in the fridge at home to avoid turning the oil into a hazard.

Keeping hot peanut oil in the car can easily cause spoilage, alter the taste, and may lead to leakage, contaminating the car interior. Safety comes first. The high temperature inside the car in summer breeds bacteria, and consuming spoiled oil can harm health, especially for families with children. I recommend storing it indoors in a cool place to maintain freshness and avoid taking risks.

Having driven for decades, I've seen many cases where storing oil bottles in hot weather causes trouble—bottles expand, leak, are hard to clean, or even pose fire risks, especially in older cars. My advice is not to leave oil containers in the car for too long. Choose a shady corner in the trunk for short trips and clean up promptly afterward. Using insulated bags is even better.
