The VW T-Roc has driven 120,000 kilometers, and it's showing a low coolant level warning. When you opened the radiator, brown liquid overflowed. After that, you drove another 200 kilometers without other issues, but the warning light is still on. What could be the problem? Is the brown liquid engine oil?

How many kilometers can I drive after the fuel level warning light comes on?

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?

The mechanic said my radiator is leaking, but I haven't noticed any decrease in the coolant reservoir, and there haven't been any warnings on the dashboard. Should I replace the radiator now? Thanks for any advice!

Today, while driving, the engine warning light suddenly came on. No other lights were on, but I felt the engine trembling and it lacked power. After driving for about 150 meters, during idling at a red light, the engine vibration was quite noticeable. When the light turned green and I accelerated, the trembling became more pronounced and it lacked acceleration. I pulled over immediately, waited for about 10 minutes, and after restarting, everything was back to normal. I restarted a few times afterward and everything was fine. The last time I started the car, I drove a few kilometers home and it was normal too. Has anyone experienced this issue? Does anyone know what might be going on?

I bought a second-hand 2011 manual 2.0 GL. According to the specs, the fuel tank is supposed to be 65 liters, but the most I've ever filled is around 48 liters, even after the fuel light came on and I drove another 60-70 kilometers. What's going on here?

My 2013 manual 2.0 Peugeot 3008 stalled twice while idling with the AC on for forty minutes yesterday. Can anyone explain what the issue might be? I drove another 320 kilometers on the highway afterward, but I'm still worried.

Does your 1.6 naturally aspirated engine consume oil too? Mine has only run about 90,000 kilometers, and after the last maintenance, I drove less than 2,000 kilometers before the oil light came on. When I checked the oil dipstick, it couldn't even reach the oil level.

How to deal with oil burning? Today, while driving over a bump, the car jolted and the screen displayed a warning: "Low oil pressure, please stop." The warning flashed briefly and disappeared when I returned to a flat road. When I checked the dipstick, the oil level was very low. I just had maintenance done 1,000 kilometers ago. How should I repair this situation with a 1.6 naturally aspirated engine?
