Hello Nairalanders,

I talk a lot about Engineering Certainty vs. Street Myths. Recently, a car owner used the CarMadeSimple™ 5-Star Engineering Checklist to verify a move he had already made for his 2009 Kia Rio.

He had already switched from the traditional 20W-50 to 10W-40, but he used our checklist to cross-reference the chemistry.

The CarMadeSimple™ Verification:
The photo he sent back (attached) shows he’s doing it right:
1. The Oil: TotalEnergies Quartz 7000. It’s a 10W-40 that carries the API SN rating. This is decades ahead of the 'thick' 20W-50 API SF oil most people are told to use.
2. The Filter: He’s using a Genuine Kia Motors filter. Most people don't realize that the bypass valve setting in a genuine filter is critical for maintaining oil pressure.

The Engineering Reality:
Many people are afraid to use the correct weight because they think Nigeria is too hot. The truth? This Kia is now better protected at high temperatures than it ever was on thick, outdated oil.

Age is just a number; Chemistry is the reality. If you are still using thick oil because your mechanic said so, you are gambling with your engine's life

Drive safe, drive simple.

Now looking at the Total 10w40 looks semi synthetic

Mobil 1 10w40 high mileage would have been great.. The high mileage addictives would have clean the sludge at a better interval...

Mobil 1 10w40 high mileage would have lasted roughly 7k Miles and that is 7k miles of engine cleaning compare total 10w40 that can only do 3k miles of engine and sludge cleaning

If your car has over 75k miles and you are not using high mileage oil , u are wasting money time

You’ve made a good observation regarding High Mileage additives, but at CarMadeSimple™, we prioritize Chemistry and Operating Hours over brand names and odometer guesses.

Whether it’s Mobil 1, Total or what have you, the engine’s survival in a Severe Service environment depends on the API SN standard and maintaining proper drain intervals based on engine stress, not just miles.

This Kia is in Recovery because we prioritized the correct Spec over street-level brand debates.

Logic always beats a guess.

But the fact remains that 10w40 high mileage Full synthetic would have been a better to clean up the kia for recovery.......

Semi synthetic 10w40 would have to be changed every 3k miles to clean out the sludge....

Meanwhile 10w40 Full synthetic high mileage would need to be change every 10k miles , To be on cautiou side Chang every 7k .. it doubles the change interval of the semi synthetic 10w40 Total.......


Facts remain that Full synthetic outweigh semi synthetic oil any Time and day...

It’s clear you’re moving the goalposts because your initial Mobil 1 argument couldn't stand up to CarMadeSimple™ logic. Now you’ve pivoted to Full Synthetic and 10,000-mile intervals.

Let’s use some engineering common sense:
You can buy the most expensive, premium bowl of Akamu in the world. If you leave it sitting in the sun for two days, does it matter how much it cost? No. It’s sour, it’s fermented, and it’s unfit for consumption.

Oil is the same. Oxidation and Thermal Stress don't care about your Full Synthetic marketing labels. In Lagos traffic, your engine is cooking the oil while the odometer isn't even moving.

The Forensic Reality:
Contradiction: You started with a brand (Mobil 1), now you’re hiding behind a category (Full Synthetic). Real Engineering focuses on Specs (API SN/SP) and Operating Conditions.
1. The Danger: Suggesting a 16,000km (10k miles) interval for an engine in a Recovery Phase is professional negligence. You’re telling a patient who just started a diet to go run a marathon.
2. Severe Service: If the car is idling for hours in traffic, that oil is working, even if the miles say zero.

At CarMadeSimple™, we don't gamble with 10,000-mile Street Myths. We stick to the physics of Severe Service. Keep the marketing; I’ll keep the engines running.

This na long epstile baba......my mouth 👄 no good ☺️

On your post you used Total 10w40 7000 semi synthetic for a kia car that had sludge from 20w50 oil . And you stated that the total 10w40 was used as a recovery to clean out sludge.. ( I agree with you) no be fight......

I than stated that full synthetic Mobil 1 10w40 high mileage would have a great alternative to the semi synthetic Total oil .....

A full synthetic oil naturally cleans out sludge especially if it is high mileage formula. And it will have a longer oil change interval...... A semi synthetic oil is not that powerful.......dey no be mates at all


Mobil 1 USA Full synthetic 10w40 high mileage. Would have done a great job than the Total 10w40 semi synthetic,.

due to the cleaning properties and addictives the Mobil 1 10w40.. plus longer intervals instead of 10k miles oil change interval compare to the Total 10w40 semi synthetic 3k oil change interval... So instead of doing 10k miles oil interval on the Mobil 1 10w40 high mileage, u can do at 7k miles.. The sludge in that Kia will surely wash out faster and cheaper.....

Baba Focus focus focus
Coz me I no go follow you agure again
Focus focus focus baba
I no dey go follow fight again

I go see u later

Once u focus wetin I dey tell you
