Volvo S80 oil change

1. According to the engine characteristics of Volvo, just change the oil by mileage.

2. Engine cleaning agent has little effect and is only used when there is too much carbon deposit in the throttle. (If it is a cleaning agent outside the engine, it is to wash the dust on the engine surface. If there is not much dust outside the engine, it can be cleaned if it is dirty. )

3. Engine protectant This is extra protection. If the oil you use is fully synthetic, it can already protect the engine well. In this regard, it is still recommended to use the opposite grade of engine oil. You can't buy inferior products cheaply, otherwise it will do great harm to the engine, and no amount of protective agent will help.
