The Mazda3 uses 0w20 oil. The functions of the oil are: lubrication, auxiliary cooling, cleaning, sealing and leak prevention, rust and corrosion prevention, shock absorption, and anti-wear. Taking the 2021 Mazda3 as an example, it belongs to the compact car category, with body dimensions of: length 4662mm, width 1797mm, height 1445mm, wheelbase of 2726mm, and a fuel tank capacity of 50 liters. The 2021 Mazda3 has a front suspension of MacPherson independent suspension and a rear suspension of torsion beam non-independent suspension. It is equipped with a 1.5L naturally aspirated engine, with a maximum horsepower of 117ps, maximum power of 86kw, maximum torque of 148nm, and is paired with a 6-speed manual transmission.

Over the years driving my Mazda3 (Axela), I've consistently used 0W-20 full synthetic oil, which is specifically designed for the low-friction architecture of SkyActiv engines. It delivers smoother power response and improves fuel efficiency. I recommend changing the oil every 5,000 to 8,000 km to prevent accelerated engine wear. For brands, I typically use Shell or Mobil – just ensure it carries ILSAC GF-6 certification and avoid suspiciously cheap counterfeit products. Cold starts in winter remain effortless, unlike cases where people use higher-viscosity oils like 5W-30 that actually increase fuel consumption. During routine maintenance, always check the oil filter to maintain optimal vehicle condition.

As a car enthusiast, I've gone through several oil changes. For the Mazda3 (Axela), 5W-20 synthetic oil works best. I've used Castrol Edge and noticed significantly reduced engine noise and smoother acceleration. Remember, the new car manual specifically recommends low-viscosity oils like 0W or 5W - don't arbitrarily switch to 10W as it might cause insufficient lubrication during summer heat. For oil change intervals, I do it every six months. DIY changes are simple and cost-effective - buying oil and filter online costs just over 200 yuan. I recommend beginners purchase from authorized stores and avoid randomly adding oil for convenience. Proper engine protection ensures worry-free driving in the long run.

To save money on car maintenance, start by checking the oil certification when choosing engine oil. For the Mazda3 (Axela), 0W-20 or 5W-20 full synthetic oil is sufficient. I've tried store-brand oils without issues, and they cost just over 100 yuan. The key is to change the oil regularly every 6,000 kilometers—don't delay to avoid higher repair costs later. Higher viscosity oils aren't suitable for its precision engineering and can accelerate engine aging in hot summers. I usually compare prices online, buy quality oil, and change it myself to save on labor costs and extend the car's lifespan. Don't fall for sales pitches pushing expensive, unnecessary premium oils.

Car enthusiasts who seek driving pleasure pay great attention to engine oil selection. The Mazda3 (Axela) paired with 0W-20 low-viscosity synthetic oil delivers racing-car-like throttle response while protecting the engine from high-temperature wear. I've used Total's full synthetic oil and found it provides better stability at high speeds with smoother acceleration. Adjust for climate changes - opt for 0W oil in winter for better cold starts. Don't exceed 8,000 km between oil changes. Combined with a high-quality oil filter, this affordable maintenance approach can deliver lasting performance improvements and an overall more enjoyable driving experience.
