Reasons For Subaru Forester High Oil Consumption
2
Motor oil is something that lubricates moving
metal parts of your car engine.
3
In addition to lubrication, engine oil has
several other functions, like-

• Corrosion and oxidation inhibition
• Sludge and impurity removal
• Engine overheating prevention

4
But did you know that your car engine consumes
some oil?
5
Is it normal for a car to burn/consume some oil?
6
Yes, it is quite normal for a car engine to burn
a little oil (not more than 0.05 ).
7
However, excess oil consumption is a cause of
concern.
8
Listed below are a few reasons why your car may
consume too much engine oil.
9
What causes high oil consumption in Subaru
Forester?
10
Broken Piston Rings
11
This is perhaps the most obvious cause of high
oil consumption in a car.
12
In combustion engines, piston rings are
responsible for doing the following things-

• Seal the combustion chamber
• Facilitate heat exchange between the piston and
  cylinder wall
• Reduce friction between the piston and cylinder
  wall

13
Cracked rings will make your car engine burn an
excessive amount of motor oil.
14
Faulty Crankshaft Oil Seal
15
Leaking crankshaft seal is another reason why
your car may consume more oil.
16
Placed between the crankshaft and timing cover,
the crankshaft oil seal prevents oil from leaking
out.
17
If it goes out, you would notice a sudden rise in
oil consumption in your Subaru.
18
Bad Driving Habits
19
This might sound to you a bit odd, but aggressive
driving habits can cause high oil consumption in
your car.
20
Aggressive driving habits can also give rise to a
variety of other problems.
21
Therefore, you should improve your driving skills.
22
Bad Oil Quality
23
Using wrong grade motor oil can also result in
high oil consumption in your car.
24
Therefore, only use factory-recommended engine
oil in your Subaru.
25
Faulty Crankcase Ventilation
26
In some instances, issues with the crankcase
ventilation system can result in high oil
consumption in your car.
27
Bottom Line
28
High engine oil consumption in your Subaru is a
sign of serious engine trouble.
29
Get your engine checked out by a mechanic to
diagnose and fix the exact issue.
