Facts About Motor Oil

Facts about Motor Oil

At any speed, oil in a small car works twice as hard as in a big car.

Smaller cars with their 4-cylinder engines circulate their oil twice as fast as in the big sixes and eights.  They run at 25 to 30 percent higher revolutions throughout their entire performance range. So there is more friction and heat in the small car engine.  The heat in a small engine can drain the life out of an oil which can keep it from cleaning and lubricating properly.

It can also cause sludge and other kinds of deposits to form and clog passageways in the engine.  From there it’s only a short step to pre-ignition, power loss, and premature wear.  Small, as well as big cars, need proper maintenance and care.  Although small cars are easy on gas, easy to handle, and have smaller engines, they’re not easy on oil.




Changing Oil

The standard for most of the cars is to change oil every 5,000 kilometers or three months, whichever comes first or as often as possible depending on your driving habits and the road conditions.

Have it drained only just after a hard drive, at least 15 kilometers.  When the oil is hot and thin, sludge will not settle and harden at the bottom of the oil pan.  Or if you leave the car at a service station for a change later in the day, the cold sludge won’t flow out.

Filling with New Oil

Supplemental additives are not essential and are an unnecessary expense.  A good oil brand already has special additives in it.

If you want your engine to run well, do not add things to your crankcase. Put in good quality motor oil and change it only according to the manufacturer’s recommendation.  Use only brand name oil and those that are marked and conforming to SAE specifications.

You should also know that “SE” designation for motor oil which meets the requirement for high-temperature engine performance is recognized by automotive and petroleum industries.

An oil with low viscosity grade (like SAE 10W) will flow freely to help a cold engine start, especially during cold weather.

An oil with high viscosity grade (like SAE 40) is thick enough to protect a hot engine, especially during summer.

But aside from those SAE ratings, there are so-called multigrade that can do both (like SAE 10W-40).

Fill up to the full line on the level gauge.  If low, add oil up to the F line.  Never overfill the crankcase.  Too high on oil level lets he crankshaft splash through the oil causing excessive foaming and may lead to excessive oil pressure.

Facts about motor oil-dipstick

To prevent overfilling, the engine should be shut off for about two minutes before removing the dipstick.  This allows oil in the lines and engine passages to drain back into the crankcase.  Note:  when checking the level of engine oil, make sure the car is standing on level ground.

If oil is leaking out around the drain plug car’s oil pan, check if the plug is tight.  If it is tight do not apply a lot of muscle to make it super tight.  Over tightening the plug will ruin thread since it has a fine thread.  Chances are the plug gasket has deteriorated and needs replacing.

Changing oil is not just a practice that car owners love to do.  It is a significant thing in the life and service of the car engine.  An efficient car engine oil maintenance means efficient delivery of services to people by the person who owns it.


The Problem of Oil Leak

Before we leave this discussion I would like to remind everyone an issue that anyone might raise.  Someone might say, why is the engine oil dissipates early before the scheduled oil change?  I keep on adding a half liter or nearly a liter every 500 hundred kilometers or every long drive yet I do not see any drip on the floor when in the garage.

The question is, how did you know it?  Is it through the oil pressure gauge or through the dipstick?

Often times the oil pressure gauge doesn’t tell the truth, especially to old cars maybe because of electrical or hardware problems.

But it is wise for the driver to always double check it through the dipstick as I usually do.  Now, this is what I discovered lately. I did not see any drop of oil in the park area but when I checked on the dipstick the oil has dissipated.  In fact, I had twice added oil to fill it to the measure because oil change is yet to come.

One time when I was checking something my eyes were set on the stabilizer.  It was a little bit wet with oil and I thought it was just an accidental splatter.  But that led me to think I have to see where it come from.

I have to remove the cover as you see in the video below so I can check where the leak is coming from.

After removing the cover I have to determine what part is leaking.  I have prepared a video for you to see what I did.  You can watch it below.


Fixing the oil leak

Sometimes it’s deceiving what part is leaking but don’t be in a hurry to do things.  You have to be patient in locating the source of the problem.  From the wet wheel stabilizer that led you to open your engine’s front cover shown below (whatever be the model).  Trace where the oil come and don’t be fooled by what you see at the lowest part that may have been just a deposit of a long leak.

Start determining traces of oil leaks from the top suspected possible parts that could easily be perforated through high heat like cylinder head cover gasket, camshaft oil seal, cylinder head gasket, front main oil seal, crankshaft oil seal, and oil pan gasket.


Areas of oil engine leakage are as follows:

Now, this is a warning to every car owner, a driver, or anyone who uses a car.  Be a keen observant with regards to oil dissipation in the engine.

If there are leaks you can see through either of the oil seals identified that is a lot easier and fewer expenses by just replacing those parts.


More Serious Issue
However, if there are no leaks anywhere outside your engine but oil dissipates before the next oil change schedule, that is a more serious issue.  Leaks are no longer outside the engine but it’s inside it.  Why?  Your valve seals or the valve seats may now need replacement.  If not the valve seals it maybe the piston rings so you need to inspect the emission smoke of your car.  A related article (please see the article on bluish smoke) will show you why I said this for your guide.

  1. Interesting facts indeed! Unfortunately, there are still many people who are not aware of the importance of changing oil and maintaining their car in general. Those who don’t have car maintenance are contributing to the negative negative effects on our lungs but also on the environment (air pollution, and oil leaks in the ocean). I’m looking forward to alternatives like the electric car that will help improve the situation.

    • Thank you Dira for your comments. I hope all motorists give importance to the changing oil. It is so important in prolonging the service life of any engine.
      You are also right that it will help in the preservation of our health and also the environment. I hope the electric cars will do good in terms of power as the fuel driven engines but for sure they are better alternatives when it comes to life care and preservation.
