Why is Subaru oil filter on top of engine?

Why is the Subaru oil filter on top of the engine?
The Subaru oil filter is located on top of the engine for several reasons. One reason is that it makes it easier to access and replace the oil filter during routine maintenance, such as oil changes. This design choice is appreciated by DIYers who prefer to work on their own cars and avoid getting hot oil on their arms.
Another reason for the top-mounted oil filter is related to the engine’s design. Subaru engines are horizontally opposed, also known as “boxer” engines. In this type of engine, the cylinders are arranged in a flat configuration, with the pistons moving horizontally. This design allows for a lower center of gravity and better balance. The top-mounted oil filter is a practical solution that works well with the layout of the boxer engine .
Additionally, Subaru’s lean manufacturing practices may have influenced the decision to place the oil filter on top of the engine. By eliminating unnecessary part numbers and simplifying the design, Subaru can lower costs and streamline production.
It’s worth noting that the top-mounted oil filter is not unique to Subaru. Other car manufacturers, especially those with horizontally opposed engines, have also adopted this design choice.
Overall, the top-mounted oil filter in Subaru vehicles offers convenience during maintenance and is well-suited to the design of their horizontally opposed engines.

On what is the oil filter usually mounted?

Car engine oil filters are sometimes referred to as spin-ons because the filter element sits within a can that is attached to a base plate which is spun onto a threaded mounting post and head-plate on the engine block. A gasket or o-ring provides the seal between the base plate and the head-plate.

What is the oil problem with Subaru?

Consumer Reports on Subaru Oil Consumption Issues
As a result, the new engine designs suffered restricted oil durability. Some consumer posts suggested that the piston ring design was the source of the problem. As a result, oil bypasses the piston and results in premature combustion.

What is the most common engine problem in Subaru?

What kind of engine problems does Subaru have? The most common problem you will hear about is blown head gaskets on the 2.5 ej motor.

Why are some oil filters on top of engine?

And get rid of that rattle. So what we offer is an adapter it’s a spin on adapter that has a check valve on the outflow. Side. And is simple to install.

Is it better to have oil filter on top or bottom?

If it is a cartridge style filter, like GM used on the HFV6 from 2004 onwards, then a top mount location is ideal – the housing stays mounted to the engine, and you simply unscrew the cap. It’s neat, clean, and doesn’t spill oil everywhere. If this was located under the engine, it would be a messy job.

Should you prefill an oil filter?

While it’s not strictly necessary to pre-fill the oil filter when performing an engine oil change on a regular passenger car, doing so can have some benefits. Pre-filling the oil filter helps reduce the amount of time it takes for the engine to regain full oil pressure after the oil change.
