How Much Fuel for Long-Term Storage?
If you own multiple vehicles or frequently travel abroad or to other provinces for extended periods, you may have wondered: How much fuel should be left in the tank when a car is parked for a long time? Should you leave the tank nearly empty to avoid old fuel sitting inside, or should you fill it up completely before storing the vehicle?
The answer may surprise you. In most cases, keeping the fuel tank at least half full or ideally between three-quarters and nearly full is the better choice.
Why Fuel Level Matters During Long-Term Parking
Many drivers assume that leaving only a small amount of fuel in the tank is beneficial when a vehicle will not be used for weeks or months. However, this can actually create problems over time.
When the fuel tank contains more fuel, there is less empty air space inside the tank. This reduces the likelihood of condensation forming due to temperature fluctuations. In countries with hot and humid climates, such as Thailand, moisture can accumulate inside a partially empty fuel tank when the vehicle remains parked for an extended period.
Skip the Worry with a Rental Car
If you're planning a long trip and don't want to worry about leaving your own vehicle parked for an extended period, choosing a Car Rental can be a convenient alternative.
Whether you need transportation for a weekend getaway, a business trip, or an extended vacation, renting a vehicle allows you to travel without concerns about vehicle storage, maintenance, or wear and tear.
