In this article, we will explore how often McDonald’s changes the oil in their fryers and what steps they take to ensure the safety and quality of the food they serve.

McDonald’s Oil Change Frequency

McDonald’s is the world’s largest fast food chain, serving up millions of burgers and fries daily. To keep up with this high demand, McDonald’s needs to ensure their kitchen oil is always fresh, clean, and safe. To ensure this, they have established a regular oil change frequency.

McDonald’s commercial-grade fryers use a blend of vegetable oil and canola oil. To preserve the quality and safety of their cooking oil, McDonald’s requires that each of their fryers be drained and refilled with fresh oil every six to eight weeks. This regular oil change allows them to ensure that the oil used to prepare their fried food is always fresh and of the highest quality.

To ensure this oil change process is carried out, McDonald’s has implemented a strict maintenance schedule for each of their fryers. Every six to eight weeks, a trained technician visits the restaurant to drain and refill the fryers with fresh oil. This process also includes a thorough cleaning and inspection of the fryers, to make sure they are operating safely and efficiently.

Oil Quality Checks

In addition to the regular oil change frequency, McDonald’s also has a series of quality checks in place to make sure the oil is always safe for consumption. Each time the fryers are refilled with fresh oil, a sample of the oil is taken and tested to ensure it meets the standards set by McDonald’s. The oil is tested for temperature, acidity, and viscosity. If the oil fails any of these tests, it is discarded and replaced with fresh oil.

Each McDonald’s also has a fryer thermometer, which is used to ensure the oil is at the ideal temperature for cooking. The thermometer is checked regularly and any discrepancies are reported to the restaurant manager. This helps to ensure that the food is cooked in clean, safe oil at the ideal temperature.

Oil Disposal

Once the fryers have been drained and the oil has been replaced, the used oil is disposed of in a safe and responsible manner. The used oil is collected in a storage tank and then taken to a licensed oil disposal facility. At the disposal facility, the oil is recycled and repurposed for other uses. This helps to ensure that the oil is not wasted and is disposed of in an environmentally friendly manner.

Oil Storage

McDonald’s restaurants are required to have a designated storage area for the oil. This area must be kept clean and well-maintained at all times. The oil must be stored in a safe, sealed container and kept away from food preparation areas to prevent contamination. The oil must also be kept away from any other combustible materials to avoid the risk of fire.

Oil Quality Tests

In addition to regular visual inspection and quality checks, McDonald’s also performs regular oil quality tests to ensure the oil is safe for consumption. These tests include checking the temperature, acidity, and viscosity of the oil. The oil is also tested for any foreign particles or contaminants. If any of these tests fail, the oil is immediately discarded and replaced with fresh oil.


McDonald’s takes the quality and safety of their cooking oil very seriously. To ensure the oil is always fresh and safe to consume, they have established a regular oil change frequency of every six to eight weeks. This process includes draining and refilling the fryers with fresh oil, as well as performing regular quality checks and oil disposal.
