Can a Diesel Can Hold Gasoline?
2 Answers
Diesel cans can hold gasoline. Here are some precautions for oil storage: 1. Seal for storage: After maintenance, the remaining oil should be sealed with the lid as soon as possible, preferably sealed with wax. 2. Store in a cool place: Oil is prone to deterioration under light and high temperatures, so the remaining oil should be stored in a cool and dry place to avoid accelerating its deterioration. 3. It is recommended to use the remaining oil within six months: When using the remaining oil, handle it gently and pour slowly, as there will be many impurities precipitated after long-term storage of opened oil, and the upper layer of oil can still be used.
I remember a few years ago when I went camping, trying to save money, I used an old diesel can to store some gasoline. As soon as I opened the lid, the strong fumes made me dizzy, and the gasoline evaporated so quickly it almost sprayed out. Luckily, I didn’t light a cigarette, or it could have caught fire. The reason is simple—diesel cans, like those ordinary plastic containers, are designed only for thick diesel fuel. Gasoline is much thinner and corrosive, and over time, the walls of the can soften, crack, and leak. Or worse, residual diesel mixed into a new car’s engine could damage the spark plugs. Since then, I’ve gone straight to the store to buy a safety-certified, dedicated gasoline can with an explosion-proof metal design for extra security. On car forums, people often share lessons like this, emphasizing not to cut corners by using the wrong containers—especially in homes with kids, where gasoline leaks can lead to serious accidents. Now, every time I refuel, I keep two clearly labeled cans—one for diesel and one for gasoline—just to be safe.
