For example, if you change from a 15W-40 to a 10W-30, your oil consumption will increase.Ĭhanging your oil in the proper intervals will also help with oil consumption. Lighter viscosity oils will be consumed in slightly higher amounts. The viscosity of the oil you use in your engine will also affect how much oil your engine naturally consumes. The harder an engine has to work, the more oil it will consume. An example of an extreme condition is operating in mountainous terrain. Things such as heavy loads and extreme conditions will increase the demand on an engine. Once the engine begins to come to the end of its life cycle, the rate of oil consumption tends to rise again.Īn increase in the demand placed on an engine will also increase the oil consumption. The consumption will stay at that rate for a while. To help quicken this period, refer to our blog on the engine break-in process.Īfter an engine is fully broken in, it will consume less oil. At the beginning of an engine's life, it will have a break-in period in which it will consume a higher level of oil.

The amount of oil an engine consumes will naturally change with the life of the engine. There are several reasons that an engine will consume oil that are normal, and do not signal that something is wrong. Below are some common reasons why diesel engines will consume oil.įactors that Affect Normal Oil Consumption Any consumption above these given levels is excess consumption and should be addressed. Each engine will have a natural and acceptable amount of oil consumption, which you do not need to worry about.
