Can you tell me how much oil the 2010 Mazda 6 2.5 model can hold?

The 2010 Mazda6 with a 2.5 liter engine requires 5.3 quarts of oil, including a filter. The manufacturer recommends using SAE 5w-20 complete synthetic oil for all temperatures. It is advised to change the oil and filter every 5000-7500 miles to maintain optimal engine performance. Failing to do so can lead to decreased lubrication of internal engine components like pistons and cylinders due to loss of viscosity. The cost of oil can vary from $5 to $10 per quart depending on whether it is traditional or synthetic and its brand/quality. Additionally, it is important to replace the oil filter when changing the oil, which typically costs between $10 and $20, depending on the brand and quality. When tightening the drain plug, be careful not to overtighten or strip it, as this could result in oil leaks. The recommended torque for the drain plug is 30 ft/lbs.
