What type of gasoline does the Mazda 6 use?
2 Answers
Mazda 6 uses 5W-30 engine oil as specified by the manufacturer. The grade after the oil classification indicates its viscosity specification. 'W' stands for 'Winter', meaning it is suitable for winter use. The number '5' before the 'W' represents the viscosity at low temperatures. The smaller the number, the better the low-temperature fluidity of the oil, the stronger its cold resistance, and the lower the ambient temperature it can be used in, providing better protection for the engine during cold starts. The '30' after the 'W' refers to the viscosity at 100 degrees Celsius. The higher the number, the higher the viscosity and the stronger the resistance to high temperatures. If the engine is the heart of a car, then the engine oil is the blood in the heart, which is crucial. If the engine lacks oil or the oil quality is poor, it can cause engine damage or even total failure. In addition, engine oil also plays roles in cleaning, cooling, buffering, and protection. Currently, there are three main types of motor vehicle engine oils: mineral oil, semi-synthetic oil, and synthetic oil. Mineral oil refers to oil made from petroleum-refined mineral base oil combined with additives. Semi-synthetic oil is based on mineral oil with the addition of synthetic oil additives. Fully synthetic oil is made entirely from chemically synthesized base oil.
I've been driving a Mazda 6 for five years and always use 92 octane gasoline. The manual clearly states that 92 or higher octane is recommended, and 92 octane is perfectly sufficient for the older naturally aspirated engine. However, if your car is the later turbocharged version with Skyactiv-X technology, you'll need to use 95 octane. The key is to stick to one type of gasoline—don't switch between 92 and 95 frequently, as it can cause unstable engine combustion. Always try to fill up at reputable gas stations, as smaller stations may have inconsistent fuel quality, and even their 92 octane might be diluted with water. A friend of mine always went for cheaper gas at small stations, and ended up with frequent engine warning lights and thousands in repair costs. Following the manual's recommendations is the way to go—it saves money and hassle.
