1. Basic situation description: mileage driven: 59500 kilometers, driving life: 4.5 years, engine model: 274920118… It is expected to complete a 60,000-kilometer maintenance project this month. For projects that have been maintained at their own expense in the past 5 years, the spark plug and the air conditioning filter element have been replaced once; in October 2021, two Bridgestone anti-tire strips were replaced because serious cracks were found during tire repair.
2. The 60,000 maintenance suggestions given by the 4S shop: B maintenance + replacement of transmission oil + replacement of brake fluid + replacement of air conditioner compressor oil + replacement of air conditioner filter element (I proposed it), the total price is less than 8000 yuan, and it also proposed that the engine be in-depth maintenance is an option and has been passed by me. Later, after checking the maintenance manual that came with the original car, I found no item to replace the air conditioner compressor oil, and I planned to cancel it. I have been driving for 26 years, and I have never repaired the air conditioner of my car without even adding fluorine to it. I wonder why I need to change the air conditioner compressor oil.
3. I checked the cost of parts and components and found that the cost of original parts purchased online was only more than 3000 yuan. I considered buying parts and going to a repair shop for repair. The parts were already in the shopping cart and had not yet been placed.
4. We plan to replace two tires that have been in use for nearly 5 years, and currently tend to consider domestic tires.
5. Current issues
1. It is said that you must choose the right model of gearbox oil. Did I choose the right one? Is the model of the air conditioning compartment correct? Are there any problems with other accessories?
2. The tire model of my original car is 245/45R18 100Y. Which domestic tire model should I replace with is the best cost-effective one?
