What Type of Engine Oil is Suitable for the Mazda Atenza?
2 Answers
The Mazda Atenza can use the original fully synthetic engine oil with a viscosity of 0W-20. If you want to change the oil during later maintenance, you can choose international brands such as Shell, Mobil, or Castrol. It is recommended to use 5W-30 or 0W-30 engine oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Mazda Atenza is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out. Use a special wrench to remove the oil filter. Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add the new oil through the oil filler cap on the engine's valve cover, usually filling about three-quarters of the oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If there are leaks, repairs should be made. After stopping the engine, pull out the oil dipstick to check if the oil level is within the standard range.
I've been driving the Mazda6 Atenza for several years, and engine oil selection is not something to be careless about. The manufacturer recommends 5W-30 synthetic oil because this viscosity suits high-revving engines, especially in maintaining smooth lubrication during frequent stop-and-go city driving. I once mistakenly used 10W-40 and felt sluggish acceleration with significantly higher fuel consumption, so I quickly switched back. The advantage of synthetic oil is better fluidity, quicker cold starts, and slightly reduced engine noise. Remember to change the oil every 5,000-7,500 km, and pay attention to oil level checks during summer heat to avoid excessive evaporation. Don't skimp on quality by buying inferior products—excessive carbon buildup can shorten engine life. The manual also emphasizes API SN or SP grade standards, so choosing reputable brands like Shell or Mobil is more reliable. Additionally, pairing with a good oil filter can enhance oil performance, and the overall cost isn't expensive. A well-maintained engine makes driving more comfortable.
