a. Excessive fuel consumption

Checking a vehicle for a problem in the face of excessive fuel levels is always a great way to find the solution. Newer models of this Subaru usually provide excellent levels of fuel economy.

However, it should be noted that this is a larger vehicle compared to other Subaru models.

Excessive fuel consumption can be due to different factors, such as an improper combination of air and gasoline.

An improper mixture of these two main factors could lead to excessive fuel consumption. This problem needs to be solved as it leads to higher fuel consumption and a higher driver’s budget.

The vehicle’s measurement systems may present some problems. This could also happen when it comes to the air filter.

A clogged air filter would not provide all the air needed for a rich and efficient mixture. When this happens, the vehicle will need more fuel consumption to compensate for the lack of air.

The same can happen when the air is too excessive in quantity. The vehicle will try to compensate for the increased air with a more significant amount of fuel.

Checking the air filter and the parts related to the fuel-air mixture can be efficient in finding the solution.

b. Excessive engine oil consumption

On certain occasions, this vehicle may present exhaust smoke that is too black. In general, this usually happens when the vehicle is consuming the engine oil in charge of lubrication.
