It is not without reason that we call engine oil the lifeblood of the engine. And it is not necessarily for just the reason that oil runs through the engine. It is called so because the engine oil performs several critical functions that assist in maintaining optimum engine performance and maximizing engine life as well as cooling the engine. And it is necessary to follow oil service intervals as recommended by the respective manufacturers of your brand. To ignore or extend the oil service intervals will lead to several risks and we list some major ones.

1. Increased sludge and oil soot levels.

One of the main duties of engine oil is to keep the engine parts running smoothly by collecting and suspending the dirt particles. By extending the oil change interval, you also increase the amount of soot (mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons) in the oil that will inadvertently cause sludge, thus decreasing the engine’s ability to work efficiently.

2. Reduced crankshaft bearing life.

The reduction of bearings’ life will be reduced through many factors including fuel dilution, coolant leaks, abrasive wear and corrosion. With extended oil change intervals, the levels of abrasives, fuel and coolant increase in the oil thus leading to removal of the bearing overlay and cause damage to the bearing linings.

3. Damage to engine.

Missing the oil change interval will lead to engine damages, resulting in minimizing engine durability and safety. Extended oil change interval will also lead oil contamination eventually leading to loss of engine power.

4. Cam shaft failure.

To lower emissions, manufacturers have been continuously improving cam metals, hardness, surface finishes etc to increase fuel injection pressures. If the soot in the engine oil goes overboard, the abrasive wear between rocker shaft and rocker bearing will increase leading to rocker arm failure.

5. Increased metal particles in oil.

When you extend your oil drain interval, the metal particles suspended in the oil also increase along with the kilometres your engine does.

Here are some photos below of a clean, regularly serviced engine and one that has been damaged due to sludge.

Very educative and informative post, keep it up Bro.
I will patronise your service very soon

I love this thread. I need to service my ride today!

Just imagine

What if am not driving my vehicle at all!

So how long do one have to change the engine oil often?

ok,,,I will come back to read this,when I get a car,,,,next!!

Very educative article

@op, how frequent do u think one should be doing dis considering the type of oil and car usage. I service the car I use regularly every 60days ( 04 toyota Corolla sport) using 5l Mobil 1000 and a regular oil filter while I do the servicing of our sienna which we only use on weekends once in 3months. Is this fair enough?

Cool

Reading incase..

Good one after so much thrash making front page.

How many months can we change engine oil

I ve nt change my engine oil 4 abt 2 months
Now. May God help me

I'm nt proud 2 say it though, na buhari cause am

Beside I don't out wit d car everyday, even wen I do its just 4rm my house to work & back

I don't go unnecessary places

U ve 2 think of fuel too

May God help us all.

Your vehicle is at Rick too for not driving it at all

You may not change it 2~3minths. It depend on vehicle distance cover [milage]

Alright

Abeg oil too cost this days......

Nice info, remember to use the oil recommended by the manufacturers.
Thank You!!!

Guys, it depends on mileage. IMO, for 2005 model cars upward use specified synthetic class oil and service atmost mileage coverage of 3000. Although often times I service mine before covering 3000 and I use Honda specified oil 5W20.

Going synthetic can do a lot of magic on your car. Most especially when the right oil grade is used.

The summary of the post is simply damaged engine.

Majority of Nigerian car owners don't know squat about crankshaft,camshaft failure ,sludge etc.they don't even care as far the car can crank and move

I just hope Oga gaz,ik etc dont deactivate too, like siena.

Guys, I have Mobil 1 5W-20 and Mobil 1 5W-30 Full Synthetic Engine Oil 5qts (4.73litres) imported from the US. I have over 100 jugs. Contact me on 09054039108. I will ship to any part of the country. If you are in Port Harcourt, I will deliver it to you in person.

I normally advise for used cars its better to use month than mileage to determine frequency of service. This is due to a lot of factors affecting reliability of some used cars and to avoid any disappointment, i usually recommend it to be done at minimum 4 times a year ( depending on usage).

I take this issue very seriously and I make bold to say there has never been any regrets so far.

Another thing that elongates useful life of a vehicle is proactive/preventive maintenance culture and not reactive. I have observed that most Nigerians have this terrible attitude of waiting for the car to break down or almost before doing the needful. that's why their cars mess them up when its unexpected. Don't wait until your car breaks down before you visit a mechanic workshop for early detection and fixing.

I practice preventive maintenance a lot and whenever I want to upgrade , I give warranty to whoever is buying my car..Just for the buyer to know he's buying a Car and not "Mortoo"...

I don't believe this , I have been driving my toyota corola car for almost two years now with out changing the oil and still , e no de develop fault

How much per gallon? I'm in PH.

Say good bye to that engine soon.
