Automotive oil classification: diesel and gasoline engine

1. Types and
classifications
of engine oil.
JAYSON V. LEONCIO

2. Prayer
“Lord God, guide my thoughts and
words today and bless the people who
in this demonstration. Amen”

3. Attendance
“The only reason why students
attend lecture”
A quote from a traditional teacher

4. Reminders
Pls. Observe New Normal Protocol specially in our virtual classroom
(Seat properly and relax!)
During the discussion just listen carefully and make a note.
Pls turn off your mic if you are not to tell anything so that we will not be
interrupted from different noise.
If you want to answer the question, just press raise hand button so that
I will be able to recognize you.

5. Activity 1. Jumbled!
Answer the activity to test your prior knowledge about oils by
arranging the letters to form the word that describes the statement.

6. 1. L-I-O is a liquid lubricant
usually made from crude
oil and used for lubrication
between moving parts.
OIL

7. 2. Oil L-I-F-T-E-R is a component
with filaments which removes
impurities form the oil passing
through it.
FILTER

8. 3. Oil N-A-P is a detachable
lower part of the engine
which encloses the crankcase
and acts as an oil reservoir.
PAN

9. 4. Oil M-U-P-P is a device that
forces oil from the oil pan to
the moving engine parts.
PUMP

10. 5. This is the resistance to flow
exhibited by a liquid. A thick oil
has greater V-I-S-O-C-I-S-Y-T
than a thin oil.
VISCOSITY

11. Activity 2. Watch video clip and
answer guide questions
1. What are the three functions of engine oil based on the
video?
2. Can we use any type of oil to attain those mentioned
functions? Why or why NOT?

13. Activity 2. Watch video clip and
answer guide questions
1. What are the three functions of engine oil based on the video?
Reduces the following: friction, wear, and harmful deposits
2. Can we use any type of oil to attain those mentioned functions?
Why or why NOT?
NO, because other oils may NOT be able to sustain those specified
purpose. Thus, specific engine oil is required

14. Our lesson for today…
Identify the different types and classifications of
engine oil

15. Activity 3. Oil confusing! You are to buy engine oil for your
diesel-engine car. You have the budget of 2,000 pesos and the
privilege to choose between the two oils. Which oil will you pick?
What are the factors helps you to decide on which oil to choose?
A. Price: 1,500 @ 5 Liters B. Price: 1,200 @ 5 Liters

17. What is the joke in
the clip?

18. What is SAE?
Society of Automotive Engineers (SAE) developed a numerical
classification system to define the viscosity or thickness of oil.
Basically, the higher the number in a Monograde oil, the thicker the
oil would be at operating temperature.

19. What is SAE? (continuation)
 The downside of monograde oil was that the oil would also be thicker
at cold temperature which made it harder to pump but also slower to
provide lubrication where it was needed (i.e. SAE 10W, SAE 20W, SAE
30, SAE 40)
Note: the “W” in SAE 10W means WINTER.
 Multigrade oil answers the downside of monograde oil.

20. ACTIVITY 5. SAE GUIDE! ANSWER THE FOLLOWING QUESTION:
1. WHAT IS THE RANGE OF TEMPERATURE WE EXPERIENCE IN THE PHILIPP INES?
2. IS THERE A MONOGRADE OIL APPLICABLE IN THAT GIVEN RANGE?

21. Activity 6. Pick a Diesel-Engine oil
A B
1. Is there enough evidence that the oil is for diesel engine?
1.If yes, what is the indicator that the oil is for a diesel engine?

22. What is API?
 The American Petroleum Institute (API) developed a classification system
to identify oils formulated to meet the different operating requirements
of gasoline and diesel engines.
 The API system has two general categories: S-series and C-series.
Note: Others consider “S” as spark engine and “C” as compression engine

23. What is API? (continuation)
 S-series service classification emphasizes oil properties critical to gasoline
engines.
 C-series classifications pertain to diesel engines and include those shown
below.

24. THE CLASSIFICATIONS PROGRESS ALPHABETICALLY AS THE LEVEL OF LUBR ICANT
PERFORMANCE INCREASES. EACH CLASSIFICATION REPLACES THOSE BEFORE IT. OILS MEETING
THE LATEST API CLASSIFICATION, API SP, MAY BE USED IN ANY ENGINE CALLING FOR IT OR A
PREVIOUS API SPECIFICATION UNLESS OTHERWISE SPECIFIED.

25. Activity 7. Classify my SAE and API
1.What oil will you pick to be used in Gen. Santos
City or anywhere in the Philippines? Why?
A B

26. 2. Which oil is suitable for gasoline-engine?
Why?
A B

27. Activity 8. Compare my gasoline engine oil
Two oils have the same price. Which oil will you
buy? Why?
A B

28. Abstraction
A. How do the oils are being classified in terms of:
1. SAE grade?
2. API classification?

engine oil container found in your backyard and
classify the oil in terms of SAE grade and API rating.
