How Does Engine Oil Affect Motor Engine Performance?

Please Auto Gurus I need your enlightenment. How does changing the oil for servicing a motor car affect the car engine performance?

My auto mechanic erroneously changed the oil I used in servicing my Honda car (1995 Model) from Total oil to AP (Visco 2000) and days after, the engine started making some funny noises and i was told that it was due to the change.

fotodaddy, nkc, viperman, inspired, and others kindly respond.

Timely change of car oil is crucial for the engine’s proper work. If the oil is not changed timely or its type is not chosen right, you may experience various problems. One of the reasons why the oil got spoilt a week or two after its change is that you may not have gotten the right kind. There are main kinds of it:

-Mineral oil

-Synthetic

-Semi-synthetic oil

The trick is not to mix mineral kind with the synthetic ones. If you had synthetic oil in, you can pour in semi-synthetic. However, if you wish to change to mineral oil, the engine has to be cleaned and washed well with the special cleaning oil and only then the change can be made. Otherwise, you would encounter serious problems with the engine performance.

Good motor oil need not be treated with " oil treatment "or " additives". Follow your manufacturers recommendation. They have conducted various tests and are thus in a position to advise on the oil viscosity to use based on operating conditions.

This information is available in the owners manual. If you do not have a car manual such information is equally available online or from any friend/colleague who has the same car and possibly the manual.

5w-20 and 5w-30 motor oils are available in conventional, semi-synthetic, and full synthetic form from a lot of independent vendors in-country. The brands on offer are mobil1, castrol, valvoline, motor craft, honda, Toyota, MileMaster, etc to name a few. You have to do a bit of searching online to locate them.

Many of these vendors advertise on nairaland and this website is a good enough starting point.

Read your owners manual. Most cars have a range of oil that you can use based on driving condition.

For enlightenment sake, if an approved engine oil is 5w30 for a car but in event of non availability of such decides to use a thinner oil such as 5w20 + oil treatment (to improve the viscosity), is there any danger in doing this?

OP, please go right now to change the oil with the correct brand and weight. Change the filter too. Then a month later repeat, once.

If my car this is what I'll do but I change my own oil so this will never happen to me.

The type and/or quality of oil used in a car affects to a large extent the performance. When low quality oil is used in an engine friction (wear & tear) will be high thus iron filling will be noticed in used oil. This condition if allowed to advance will create clearance between mating metals surfaces with resultant wearing out of the engine vital components. Usually, if friction not is reduced to a mechanically negligible level with quality oil in an engine there will be drags, heat,'sludge'& poor performance & delivery. It's usually adviceable to protect engine's vital components with Green Engine Revolution Technology Products - metal treatment concentrate. for more info visit: www.greenenginerevolution.com or call 08033527026 or nearest Automedics workshops.

Good day to all the Auto Lubricant Gurus in the house,

I 've a question?

I serviced my 2002 xterra with premium Mobile 1 engine oil before travelling with it to Abuja in September, 2011 and since after then, i had done two Osogbo trips. Other usage is just Island to home daily commuting. Reading this thread, I ve gained alot of insight as to what to use to service one's car. My ques are:

1. I am travelling for xmas, should i service again b4 setting out?

2. The SUV is 10 yrs old, reading from this thread, shouldnt I stop using a light oil as Mobile 1 for the 10 yr old car?

3. Considering the type of vehicle, average usage and age, what type of oil will be best to service the car with?

Thank you all in anticipation of your responses.

the danger is in swapping diff oils, ie switching 4rm synthetic to normal oils.thats a big NO NO!!!, using diff kinds of oil, i repeat kinds, not brands affects the engine severly since the o rings n seals hv already adjusted to 1 kind of oil, now switching to anoda kind of oil will make dem brittle/detoriate.

i think there are about 3 kinds of oil in the naija market.

1, SYNTHETHIC OIL

2. MINERAL OIL

3, OTHERS,

Hi guys, I just got delivery of a 2004 Volvo S60 2.5turbo and I would like some advice. The manual says recommended oil is 10W30 in tropical regions but I have gone to all reputable stations and the only one I saw was 20W50 oil. Is it safe to use that in my car, since Lagos gets pretty hot?

From several internet forums, users recommend Mobil 1 synthetic oil, so right now I am very worried as to how I can get such oil and genuine oil filters.

Thanks for replies.

Ivie,

Your technical knowledge is amazing! Many thanks.

I have started searching for Mobil 1 5w 20. My nearest Mobil service station only has 0w 40. Will search more,

Anyone who knows a Mobil station that stocks wide range of Mobil 1 oil should kindly let me know.

Ivie,

Thanks for your response. I am in Nigeria and the car is a 2007 Camry 2.4L. The manufacturer's recommended oil is 5W 20 or 0w 20. However, I used Mobil 1 0w 40 synthetic oil. I wanted to find out if I should do an oil change immediately? What oil will be best for the car in Nigeria?

Many thanks

Ivie, i should think you are fine with the current oil because of the hot weather in Nigeria,

the more regular oil change the better if you can afford it i would recommend every 8000 - 10000 kms

20W-50 is not just for heavy trucks.

It is also recommended by many manufacturers, where the engine has covered a lot of miles, and the use of thinner oils will result in excessive blow-by.

sorry poster

for late reply, been busy,

from d many posts on here, go with fotodaddy and ivvie, theres are less technical, so u can understand, easily unlike d others,

but simply put, look for d oda oil gallon, go and check d api specs on it, just compare d specs on d gallon body to that of d new oil gallon u r using , if they r d same, then ur car has a different issue, other than d oil, it maybe that d filter may not be original( wo knows dis days) but run a check, tru everything and pls drive less until ur research is over, it may just be sumtin else tat needs yur attention. have a nice day

Ivvie may have made some points

But using 5w/30 in Nigeria? I disagree

and saying 20w/50 is biased towards diesel- nna bros abeg be careful o

We may have to start backing up our facts with confirmed additive manufacturer literature

@Ivvie has provided enough points, but just to add more,

Engine Oils are typically a blend of Base oil and additives. The additives are special chemicals that are added to the base oil (sort of ordinary oil) to enable it function properly at different temperatures, with the right viscosity (fluid movement) and also protect the engine. After each blending in the plant, the different mixtures formulated are usually carefully tested in the lab to meet the requirements of different vehicle engines (including motorcycles), hence you have different types of engine oil for different engine types.

Usually, most of the oil people buy off the streets (I mean those that are not sealed and usually measured in cans) in Nigeria have very minimal additives added to it and hence not good for your engine. That's why they are cheap, as additives are very expensive and will make the lubricant price high. You need to get the right oil for your engine and you shoud be able to get that advice from a good mechanic or filling station store or from the manual of your car.

Ol boy I wonder what weight is used in Saudi. Cos for sure you will need heavier oil in hotter countries than in colder. Here in Naija, I am sure you can

t get a locally blended oil with a weight lower than 20. Meanwhile thats not to mention all the people that add "oil treatment" and increase the weight to like 60 or 70.

So what's the koko for a 2007 Accord?

What is the recommended oil that I can get here in Naija?

i may have to agree with triaophant for the reason that last year november i serviced my car (mitsubishi gallant) and used AP VISCO 2000 oil which i bought myself from a reputable dealer in isolo. everytime i check the oil, it surprises me that the colour hasn't changed much unlike previous ones i used and the engine runs better. i have decided to stick with V-2000 and to always buy myself. am even changing the oil soon and may probably do it myself.

To the poster, I do not think that the change of oil is the problem except perharps you fell into the hands of dubious auto mechanics who use refilled engine oil if you are not too observant to service customers cars. These refilled engine oil are mostly expired and they purchase such engine oil and refill it with smaller cans and containers which they sell to unsuspecting members of the public. As for your change of engine oil, though not all that advisable, it cannot radically alter the performance of your engine. I changed over from Oando to AP VISCO 2000 for over a year now on my Benz car and I can attest that the engine performance has been excellent. As a matter of fact, that engine oil is designed for cars such as Rover, BMW, Ford, Mercedes Benz, Peugeot, Jaguar, Volvo, Volkswagen, Fiat, SAAB, All JAPANESE and KOREAN cars. So you can see that your Honda falls within the cars that the AP VISCO 2000 is designed for. It has the following SPECIFICATIONS:SAE 20W 50 SJ/CH4, ACEA A3-98, E-96, MB228.1, 229.1, JASO DX-1. It is a low friction premium quality Motor oil formulated to handle all stress levels in modern petrol and diesel engines. It provides superb control over deposits, wear, oxidation, rust and corrosion. It has an ultimate engine protection, improves engine cleanliness, stop-start and extreme driving conditions, increases power output, reduces fuel consumption and enhances easy cold start. BUT MY ADVICE IS THAT NEXT TIME YOU WANT TO SERVICE YOUR CAR, DRIVE TO ANY AP STATION AND BUY JUST TWO 4 LITRES CANS OF THE ENGINE OIL BY YOURSELF AND TAKE IT TO YOUR MECHANIC. Check also whether your engine seatings are ok, check your motor fan and fan belt and see if it is wobbling, finally have a look at your wheel alignment.

every engine has it specification and the rating(octane rating) of oil which you are to use for servicing the car.now check the manual of your car for the specify oil ratings to be used,if you derivate sharply from that it might affect your car but if the ratings is in the same range you do not have to worry.

You need to specify the type of oil not only the brand.

If you look on the can you will find the API clasification. If they are similar, then changing brands really doesnt amount to much.

However, I have observed that a lot of Oil dealers adultrate the oils. If you notice, some mechanics do not break the seals of the oil can when they open it. They then sell the kegs for as much as 700 bucks. The buyers of such kegs refill with ordinary oil or even other oil types, and sell it for the price of the original.

I lost the engine of my Mitsubishi Eclipse about 8 year ago like this. And this was after an oil change at Mobil Maryland. That was the last time I was there.
