Hey folks, got a low oil warning and the next day it started making noise. Even after adding 4 liters of oil, it's still the same. Any idea why?

How many liters of transmission oil does a Smart 4-door need for a change? Do I need to remove the oil pan and replace the filter?

I recently got an 08 Mazda 2 hatchback, 1.3L automatic. It has been driven 130,000 km over 15 years. I've been driving it for about 10 days, mostly commuting in the city with a round trip of 40 km a day, but the fuel consumption is ridiculously high... After the fuel warning light first came on, I added fuel worth 200 yuan, which was 25.6 liters, and drove a total of 247 km. The average fuel consumption was 10.35 liters/km, costing 0.8 yuan/km. After the fuel warning light, the engine light turned yellow as well, what's going on??? I didn't think too much and just drove to the gas station, asked the staff to fill it up, but it could only take 34 liters before the pump stopped. The staff said it was full. Isn't the Mazda 2's fuel tank capacity supposed to be 43 liters? Why is it full so much earlier, is there something wrong? Looking for help, how should I deal with this? Has anyone experienced the same situation?

Can the Eclipse Cross only add 4 liters of engine oil?

I've got a 2009 Peugeot 307, and the air conditioning isn't cooling very well. I had it recharged with refrigerant, but it still doesn't get cold enough, especially on hot days. Any idea what might be wrong?

I drove for about an hour at night, and the battery warning light came on. Then I stopped driving. The next day, when I drove again, the warning light was off. Can you tell me what's going on and if it's serious? Thanks.

The engine warning light is on, indicating an oil leak. I changed the oil 4 days ago using 5-30w. What's going on? Does anyone know?

I've got a 2014 Peugeot 3008 1.6T that's been burning oil. I've added three liters of oil in the past 5000 kilometers. I'm thinking about replacing the valve seals. Does anyone know if this works? Has anyone else done this, and how effective was it?

How long should I wait for the next maintenance after adding semi-synthetic oil?
