What Vehicles Are Suitable for 15W-40 Engine Oil?
1 Answers
15W-40 engine oil with a viscosity of 40 is more suitable for European cars. Additional information is as follows: 1. Engine oil viscosity: There is a characteristic of engine oil viscosity—higher viscosity provides better sealing but increases fuel consumption in the engine. At idle, higher viscosity oil results in lower noise, while during driving, higher viscosity oil leads to higher noise. Lower viscosity oil, on the other hand, has fuel-saving characteristics. 2. 5W-40: 5W-40 is the viscosity grade of engine oil, and it can be used in any car. However, this grade of oil is more suitable for use in summer and autumn climates.
