What is the recommended engine oil model for the Mazda3 Axela?

The best engine oil models for the Mazda3 Axela are 0W20 full synthetic oil and 5W30 semi-synthetic oil. If you want to change the oil during later maintenance, you can choose brands like Shell, Total, Castrol, and Mobil. 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, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. The higher this number, the better the oil maintains its viscosity at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in the Mazda3 Axela 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 underneath 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 passages to drain out; Use a specialized 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 valve cover, usually filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick and ensure the engine oil level is within the standard range.
As a long-time Mazda3 Axela owner, my maintenance philosophy is simple: follow the manual religiously. The manufacturer recommends 0W-20 low-viscosity oil, which is particularly well-suited for Skyactiv engines - ensuring smooth cold starts and better fuel efficiency. I typically use Mobil or Shell full synthetic oil (SN grade suffices), offering great value. For vehicles over 100,000 km or facing extreme temperatures, consider switching to 5W-20 or 5W-30. Maintain 7,000-8,000 km intervals between oil changes, and regularly check the dipstick - don't wait for warning lights. Remember: no off-brand oils; engine repairs could cost two years' worth of oil.
I enjoy spirited driving occasionally, so the performance of the Mazda3 at high RPM is crucial. I always insist on using 0W-20 full synthetic oil, and the racing formulations from Idemitsu or Gulf are excellent choices—they protect the engine and reduce wear. If I'm doing more long-distance driving in the summer, switching to 5W-20 is a safer bet. Too low viscosity doesn't provide enough protection, while too high viscosity affects acceleration response—20 viscosity is just right. I check the oil condition every 5,000 kilometers; if the color darkens or the level drops, I change it early. Never casually switch to higher viscosity oil—the essence of the Skyactiv engine lies in low viscosity.
