10 Major Mistakes You’re Making When Changing Your Car Oil

By Autobytel.com
If you change your own oil (or even if you have a shop do it), your car may not be getting all the attention it needs. Almost everyone who has ever changed the oil in a car has made at least one of these mistakes at one time or another.
To help you learn from our mistakes (and so that you don’t have to make them yourself), here is our list of the top ten major mistakes you’re making when changing your car’s oil.
Changing the oil too frequently, not frequently enough, or not at all
It’s best to follow the oil change interval specified in your owner’s manual. If most of your driving is stop and go, you spend a lot of time idling, you tow regularly, or you live on a dirt road, you may need to follow the ‘Severe’ oil change schedule.
While changing the oil too frequently probably isn’t going to damage your engine, it is going to hurt your wallet. Not changing the oil frequently enough on the other hand can lead to costly engine repairs and the dreaded ‘sludge
Not checking the oil between changes
The recommendation used to be to check your oil every time you filled your car up with gas. Some full-service stations (remember those?) even offered to check your oil for you, and if the attendant forgot to offer, your gas was free.
Today you are probably safe checking your oil once every week or two, unless you know your car burns oil or has a leak. Some people are pedants and recommend checking it every day, which seems excessive, but better safe than sorry, right?
Not performing other routine maintenance at the same time
If you bring your car into a shop for an oil change, they’ll probably want to do a lube job, grease your doors, grease your emergency brake, and check the air filter, brake fluid, transmission fluid, engine coolant, and power steering fluid. Many times people who do their own maintenance will call it a day as soon as they are done swapping out the oil, without tending to these other tasks.
While many cars today don’t come with any grease fittings that need servicing, some aftermarket parts still include grease zerks that should be kept filled with a good quality grease.
Using oil additives
With today’s oils and engines, using an oil additive is probably not going to provide any benefits, and may in some extreme cases actually harm your engine. Generally, if your motor is in good shape, and you follow the recommended oil change interval and use the recommended type and weight of oil, using an oil additive is just going to be a waste of money.
Today’s engines often outlive the vehicles that they are installed in, even without the use of any special additives.
Using the wrong weight of motor oil
If you are still using 10w30 because that’s what you’ve always used or because that’s what you remember your mother or father buying, you’re probably making this mistake. Modern cars have tighter tolerances, and aren’t usually designed to use 10w30 anymore.
Using too expensive or too cheap a motor oil
If your owner’s manual recommends synthetic oil, you should follow the recommendation, but otherwise using synthetic might be just a waste of money. Unless your car sees severe duty such as extreme engine temperatures (some turbocharged and supercharged vehicles fall into this category, as well as some high performance naturally aspirated engines), towing, or racing, conventional oil might be the right choice for you.
Synthetic is not recommended for use in some engines, for example in rotary engines where it can damage seals unless specific care is taken to choose a compatible synthetic oil.
Over tightening the filter or drain nut
Some people seem to really like to tighten things as much as they possibly can, even when there is no reason to. Tightening a clean new oil filter with one hand is usually enough, and makes removing it much easier (you might not even need to use a wrench, sometimes just two hands are enough).
For the drain plug, if it doesn’t have a crush gasket, 20 to 25 ft-lbs is usually about right, while plugs with crush washers are usually tightened a bit more, around 30 to 35 ft-lbs. Overtightening will just cause you problems when it comes time to remove the filter or drain plug.
Not replacing the drain plug crush washer or oil filter cover o-ring
On some cars, especially those designed in European countries, the oil drain plug will use a soft metal washer to seal it. These washers are often not reusable because they are crushed the first time the drain plug is tightened down.
If you don’t replace the washer, you may end up with a slow and annoying leak. If your car uses a replaceable oil filter cartridge instead of a normal filter, you might want to consider changing the oil filter cover o-ring at every oil change as well.
Not rotating your tires
Oil changes often coincide with the tire manufacturers’ recommended tire rotation schedule (usually somewhere between 5,000 and 10,000 miles). Rotating your tires every oil change can be quite a bit of work (especially if you don’t have a lift), but should help them wear more evenly and last longer.
Not keeping track of oil changes
Usually when you get your oil changed at a shop they will place a sticker on your windshield telling you when the oil was last changed. The sticker acts as a reminder, and lets you know when the next oil change is due.
If you are changing your own oil, remember to keep track of the mileage and date, so you know when it’s time to do the next service. Otherwise, you’ll be trying to remember the exact date and mileage of your last change, or you may forget to do your oil change altogether.

FG to Open Section of Lagos-Calabar Coastal Highway December 12
By Adedapo Adesanya
The federal government is set to open Section 1 of the 700 km Lagos-Calabar Coastal Highway for public use from December 12 to 17, 2025.
The Minister of Works, Mr Dave Umahi, gave the assurance on Sunday in Lagos during a review of outstanding works on Section 1 of the highway project.
The section 1 is 47.47km long and has six lanes and two carriageways.
Mr Umahi said: “We also set aside April next year to have Section 1 and half of Section 2 fully completed and commissioned,” adding that the contractor handling the project, Hitech Construction Company Limited, had achieved more than 80 per cent of the reinforced concrete pavement.
“We are very grateful to God Almighty for his mercies, and to the President and to the contractor.
“If we are to pay for everything they have done, it will be very difficult to have this job done because there are places we didn’t envisage that we were going to be removing pits up to a depth of 20 metres.
“They had to do that because they are partners in progress for the development of the country.
“We have just about three kilometres to complete the entire sand filling from Ahmadu Bello Way to Eleko Junction, and we are excited at the work and the quality of what has been done,” the former Governor of Ebonyi State, said.
The new Controller of Works in Lagos, Mr Olufemi Dare, told the minister that a lot of settling was ongoing at Chainage 33 of the highway project, praising the contractor for high quality of work.
“Sir, it may interest you to know that the building standing is the palace of this community, and you saved this building, and they are extremely happy,” he said.
On his part, the Managing Director of Hitech Construction Company Limited, Mr Dany Abboud, said that the company would still backfill from Chainage 34 to Chainage 37.
“Dredging is ongoing, we are on track to deliver.
“We are monitoring the settlement in the swampy areas and the water body areas due to the change of alignment,” he said.
The highway, which commenced construction in March 2024, has generated a lot of controversy, with critics raising concern around cost and procurement structure.

Nord Vehicle Owner Accuses Nigerian Bank of Economic Sabotage
By Modupe Gbadeyanka
A Nigerian lender has been accused of frustrating local business owners by not financing Made-in-Nigeria vehicles but promoting the purchase of foreign vehicles.
This allegation was made by the owner of a local vehicle assembly firm, Nord Motion, Mr Oluwatobi Ajayi, in a post on X, formerly known as Twitter.
He described this as an economic sabotage, stressing that this action does not encourage local investors.
“A business owner in the oil and gas sector approached us that he would like to buy two units of the @nordmotion Max pickup for his company. Apparently, he was impressed with the vehicle after some rides with his peers in the sector.
“To my shock, yesterday, my team told me that the bank, a bank operating in Nigeria told him that they do not finance Made-in-Nigeria vehicles, and they even suggested to our customer that he should go for foreign brands instead.
“The most provocative part of this is that all of the brands they suggested to him identified as Made-in-Nigeria brands in their filings with the Bureau of Public Procurement (BPP), which means they decide who they want to be whenever it suits them.
“This is yet another example of the needless sabotage and institutional bias against Nigerian manufacturers and assemblers that we experience in this sector.
“The President aims to grow us into a $1 trillion economy. Nigerians want to buy Made-in-Nigeria products, we are working very hard to produce world-class vehicles, but some banks, who should play the role of credit facilitators, are displaying open prejudice against locally made vehicles.
“What sort of economic sabotage is this?
“Many of us who continue to assemble and manufacture vehicles here do so not just for profit, but out of patriotism and belief in the long game. We see this as a marathon, not a sprint.
“We cannot continue using Nigerian resources to strengthen foreign factories while starving our own indigenous companies of opportunities.
“If we truly want this country to be better, then we must support goods and services made in Nigeria, especially those of us who have shown we can deliver world-class standards. The support has to be real, not just in words, but in policy, in finance, and in action.
“Every time we deny support for local production, we export jobs, skills, and economic growth that should belong here,” he narrated.
