3 Answers
508 compressor requires 100 grams of refrigerant oil. Below are the differences in refrigerant oil quantities for various vehicle types: 1. Mini and small cars, small SUVs: require 600-650 grams of compressor refrigerant oil, and you can purchase 3 cans of 220-gram compressor refrigerant oil. 2. Compact and mid-size sedans, MPVs, compact and mid-size SUVs: require 700-750 grams of compressor refrigerant oil, and you can purchase 3 cans of 250-gram compressor refrigerant oil. 3. Commercial large sedans, large SUVs: require 800-850 grams of compressor refrigerant oil, and you can purchase 3 cans of 300-gram compressor refrigerant oil.
The amount of refrigerant oil to add to the Peugeot 508's compressor depends on the specific model year. Having worked on many of these cars, I've found that the oil quantity typically ranges between 150 to 200 milliliters, but you should never estimate it casually. First, you need to check the owner's manual or the label under the car for instructions, as the oil amount depends on the size of the air conditioning system and the compressor model. Adding too much or too little can cause problems. For example, too much oil can obstruct refrigerant flow, making the AC less cool, while too little oil can cause the compressor to run dry, leading to wear and a shortened lifespan. Also, make sure to use the correct oil type, usually PAG or POE oil grade. If you're inexperienced, it's best not to DIY—take it to a repair shop where they can check the oil level with professional equipment. Regular maintenance can also help prevent further issues.
Regarding the filling amount of refrigerant oil for the Peugeot 508 compressor, I think novice car owners shouldn't worry too much about the numbers—the key is finding the right information and adding it accurately. The manual usually specifies between 100 to 180 milliliters, but don't just focus on the numbers. The refrigerant oil primarily lubricates the compressor and seals the system, and incorrect amounts can easily lead to air conditioning issues or even compressor failure. I recommend first checking the vehicle's instruction plate or downloading the manual online to confirm. If you don't have professional tools, it's best to visit a repair shop—they can accurately measure the remaining oil level and add new oil to avoid efficiency losses caused by improper oil levels. Also, pay attention to the sound of the air conditioning during operation; unusual noises may indicate low oil levels and the need for inspection.
