Will Not Changing Engine Oil Increase Fuel Consumption?

Not changing engine oil will increase fuel consumption. Below is the relevant explanation: 1. Impact: Prolonged failure to change engine oil affects a car's fuel consumption. Not changing engine oil for an extended period significantly reduces its sealing, lubrication, and cooling functions, leading to decreased engine power and increased fuel consumption. 2. Specific reasons: During use, engine oil's performance gradually declines due to contamination and oxidation, and there is also some consumption. Simply topping up without changing can only compensate for the lack of oil quantity but cannot make up for the loss of lubrication performance. It's like mixing cold water with room temperature water; it can only become warmer, not cooler. Therefore, only adding oil without changing it will result in progressively worse performance.

What does it mean when Mercedes PRESAFE stops working?

Normally, the occurrence of PRE-SAFE stopping operation does not affect the use of the vehicle. Below is the relevant introduction: 1. Reason: When Mercedes displays PRE-SAFE stopping operation, it could be due to the vehicle's safety protection equipment being turned off, specifically the passenger airbag switch being deactivated. The owner can go to a service station for assistance or manually turn on the passenger airbag themselves, with the switch located on the passenger side. If these are not the issues, the owner can choose to upgrade the computer system and then clear the code. 2. Function of Mercedes PRE-SAFE: Mercedes PRE-SAFE refers to the vehicle's preventive safety system.
