Mazda CX-5 generally performs best with Mobil 5W-40 full synthetic engine oil. Mazda has not officially specified which type of oil to use for the CX-5, as long as it is genuine. Below are some relevant details: 1. The choice of engine oil should be based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher demands. 2. Multi-grade oil is recommended due to its cost-effectiveness, long lifespan, and high efficiency, providing better protection for the engine. Given the characteristics of multi-grade oil, it may appear darker or show lower oil pressure compared to conventional oil during use, which is normal. 3. If the engine is in good condition and the seasonal temperature is low, using lower-viscosity oil is advisable to ensure smooth oil flow. In high-temperature seasons or when the engine is severely worn, higher-viscosity oil helps form a protective oil film and reduces engine wear.

What does TPMS mean when displayed on the car dashboard?

The "TPMS" displayed on the car dashboard is the tire pressure warning light, which indicates that there is no signal from a certain tire pressure. If the tire pressure monitoring system warning light comes on while driving, stay calm, do not panic, immediately reduce speed and avoid sharp steering and sudden braking, and check the tires immediately. Tire pressure monitoring light on due to a punctured tire: This situation usually involves a very slow leak in a tire, making it difficult to immediately identify which tire is affected. In this case, you can use a tire pressure gauge to measure the pressure (front tires at 2.3, rear tires at 2.5). If the pressure is low, refill it and then observe the tire pressure warning light. If the light comes on again after a few days, you may need to open the tire for inspection. At a 4S shop, maintenance personnel typically adjust the front tire pressure to 2.3 and the rear tire pressure to 2.4, then reset the tire pressure warning. If there is no warning for 3-4 days, there is no issue. If the warning reappears, it might indicate a punctured tire, requiring another visit to the 4S shop for inspection. Tire pressure monitoring light on due to prolonged driving with low tire pressure: This situation usually occurs when a tire's pressure is too low, causing the tire temperature to rise during high-speed operation, which in turn increases the tire pressure. In this case, you should stop and rest or replace the tire with a spare immediately.
