When Should I Change My Oil?

Home/Blog//When Should I Change My Oil?

An engine oil change is a relatively simple service. It’s widely touted as the single most important part of your car’s maintenance schedule.
There is a good reason for this. Nothing will shorten engine life faster than missed oil changes.

But how can you tell when you should change your oil?  

Advances in technology and increased consumer awareness have created some confusion to how often this needs to happen.

The Easy Answer

For most of us, all we need to do is follow the manufacturer’s recommended maintenance schedule for oil change intervals. Their guidelines are designed to keep your car in good running condition for a long time.

Where can you find your car’s service schedule for oil changes and other recommended maintenance?

You can check the owner’s manual that hopefully you have kept in a handy place like your car’s glove box. You might also visit the manufacturer’s website and do a search to download it.

Quick lube shops have their own recommendations. One thing to remember is that these shops are speaking to a wide audience, addressing cars of every age, every mileage, and some with different needs.

While there is no harm done by too frequent oil changes, if your car doesn’t need them, that money could be better spent on other maintenance needs.

Don’t Put It Off

If you have ever put off a trip to the grocery store or waited a couple of weeks longer between haircuts, don’t do that with oil changes.

Your oil’s primary function is to cut friction.

Over time, oil accumulates contaminants and loses viscosity (the ability to flow into every nook and cranny). Contaminants cause friction as parts rub together. Friction wears out those parts faster.

The damage caused by these conditions is largely irreversible without an engine overhaul or replacement.

Waiting for the low oil light to come on can be the worst thing you can do to your engine.

You shouldn’t see that light unless your oil level is low. So you don’t want to see it. Whatever amount of oil you do have left almost certainly has lost its ability to function properly.

The good news is that your service schedule is written to have this service done long before disaster is on the horizon.

Cars are Smarter Now

For a very long time the gold standard for oil changes was 3,000 to 3,500 miles.

There are still many adherents to this philosophy, but it may not be necessary;

Advances in engineering to both engine mechanical parts and especially to oil itself have extended the oil life cycle by more than double the old number.

Do you use synthetic oil? 

Automakers recommend it for some models. It cost a little more than regular oil, but it has had the biggest impact on oil life.

The life cycle for synthetics is typically 7,000 to 10,000 miles, a big change from conventional oil.

The type of driving we do also affects our oil change needs;

Frequent cold starts, extreme heat, and towing, are all examples of types of driving that can shorten our oil life.

Also, repeated short trips (under 4 miles) is one of the most overlooked enemies of oil life.

Any of these driving conditions can create the need to shorten your service interval by 25-40% depending on the severity.

If your car is equipped with a maintenance reminder on the dash, some of the guesswork is eliminated for you.

Can you trust it?

For the most part, yes.

In the early days of automobiles the only way we had to track our vehicle’s aging was the odometer. But miles traveled is not always a good indicator of actual use for many urban environments.

[READ: Odometer Rollback Fraud – How to Protect Yourself]

With the inclusion of computers in the modern automobile we now have a way for the car to track time AND mileage. Time is important to this discussion because running time affects oil life.

But not all maintenance indicators work the same way:

Some use an electronic sensor to measure the oil quality, while others use an algorithm based on driving metrics to determine life expectancy.

If your car is not equipped with maintenance light or gauge, the owner’s manual should still be your guide.

Don’t Buy Cheap Oil

All of these scenarios assume you are using the factory-recommended lubricant.

If you have opted for something inferior you may be adversely affecting the recommendation.

It’s not worth a few dollars to shortcut on the oil.

Track Your Maintenance

Because time is important as well as mileage, it’s nice to try and plan your service visits.

The little sticker in the corner of the windshield was a small, important innovation to help us plan. Before that, many people kept a paper record in their glove box as well.

But now, with many of us carrying smartphones and having home computers, it’s gotten even easier.

    I normally have my oil changed every 3,000 miles or so. It helps me feel like I have properly cared for my vehicle. I have never looked at the manufacturing guidelines of the car though. Maybe I should see if I am changing it regularly enough or not.

The 3,000 mile interval is more than adequate in most circumstances, but you should read and understand your service schedule to be sure.

      You are wasting your money if you are changing oil at 3k miles. That’s old school thinking and is not necessary. Oil technology has come a long way and you should not be changing conventional oil until about 5k miles. If you use synthetic oil you should not change until at least 7k miles.

      • Peter April 19, 2015 at 7:44 am - Reply

        M, I agree with you on one thing. That synthetic oil gets changed at 7,000 miles. But regular conventional oil must be changed every 3,000 miles. My local mechanic that I go to is the the most trustworthy mechanic around. I asked him what if I go 5,000 miles between oil changes. He said, you will ruin your engine eventually. Conventional oil gets dirtier quicker than synthetic oil. That’s why it needs to be changed every 3,000 miles. So Im not wasting my money. You would be wasting your money if you got your oil changed every 5,000 miles because eventually your engine will start breaking down and pissing away money in repairs

          Peter, your mechanic wants to keep the pipeline to the free money going. Change your oil every 3000 miles is pure and unadulterated bunk. You will NEVER (not EVER) find a mechanic who will tell you otherwise because it is free money for them. Get your car manual out and read up on it for yourself.

          I am 61 years old and mechanics used to always refer you to your car manual for the various maintenance schedule you should follow. You will not find a mechanic alive who does that now. They don’t want you to know and miss the gravy train.

          The oil is radically different now from what it used to be. The ONLY people who will tell you to keep with the 3000 mile oil change is the local yokel mechanics. Making fools of everyone because they don’t want to stop the gravy train.

When i go to have it changed bf then they tell me its not time. So your trust worthy person is not so trust worthy. 3,000 miles is so old school!!! Oil has gotten better since then. So wasting your money.

      • John vegas November 18, 2015 at 1:32 am - Reply

        The proof is in the test results. I’ve sent my oil in to get tested many times at 5k times on mobil 1 full synthetic I had 40% more contaminants then at 3k miles. You will only benefit from good oil if you plan on keeping the car past 100k miles because most engines will do 100k with the worst oil. People also need to know that not all oil filters are created equal, filters that cost under 7$ are filled with low quality materials that do nothing to filter the oil. If you don’t plan on keeping your car for 10 years or don’t take care of the body and interior don’t waste your money on good oil the rest of the car will fall long before you see the benefits of quality oil.

Ive changed it every 3000 and my 91 ford ranger has 404000 mile my 03 ford focus 225000, and my 95 ford van 245000 miles still running good. If its to soon at 3000 I cant really complain I wasted money when my vehicles have lasted so long. But I do believe that oil tech has come long way and less frequent oil changes are required.

      Most people do not realize that changing oil too often do cause harm. This is because several seconds after changing oil engine works completely without oil. During the oil change all oil is drain from all parts to the crankcase. In some cars that use cartridge check valve does not allow complete drain, bu still… Complete volume of filter housing and all oil passages have to be filled with oil first and only then oil will get to the parts. During numerous oil changes this seconds became minutes engine works completely without lubrication. Therefore, oil change intervals have to be correct and optimized by real requirements of to avoid more harm than good results.

      • brad December 28, 2016 at 1:32 am - Reply

        The exact same thing can be said for starting your car up in the morning. After sitting in one place all night, all the oil has drained back down into the pan, none is where it needs to be. If you Chang your oil after the car has run for a few minutes like you should, there won’t be any loss of lubrication, because enough oil will be left in the bearings to provide the necessary lubrication. It is impossible to change your oil too often.

        • Vlad February 14, 2017 at 5:23 pm - Reply

          No, you are wrong. There is one way check valve either in the filter (that black or red rubber thing under the holes) or if car uses cartridge type filter, check valve is on filter housing. Its purpose is to prevent oil to go back in oil pan. When it stop working as rubber dries out (mostly on replaceable filter cars, not on cartridge type), you see oil light stays longer. If you drain oil and remove filter, all oil passages and filter housing will be empty. So, changing oil more often let engine work without oil longer, while morning starts don’t .

      • Jack smith March 29, 2017 at 2:02 am - Reply

        That is the dumbest thing i ever heard. You can not change your oil too often unless you have a new car or a new/rebuilt motor that had a break in oil in it. Once your motor is broken in, you can not change your oil too often. Doing an oil change does not leave your engine completely without oil. First of all, once you pour the oil in, you’re gettin oil on a lot of your engine parts. Secondly, oil sticks to the motor and all its parts. The cylinders have cross hatches honed into them to keep the oil on the cylinders longer. Also, your engine is not hot enough jus after an oil change to burn off the remained oil on all the parts in the 2seconds before it builds oil pressure through out the motor. Everything doesnt have to be drowning in oil. As long as its coated when the parts are moving, which it always is even after you drain it, its lubricated and not doing any harm. Egines seize because of heat and not being lubricated. The amount of time it takes to do an oil change then start the engine after its done is not nearly enough time for the oil thats still coating/lubricating all the moving parts to get hot enough to burn off before the 2 seconds it takes the oil pressure to get the oil through the motor.

        The only way to have “all the oil” removed from the engine would require a complete tear down. I will admit only residual lub remains for a very short period.

    I didn’t realize that waiting for the low oil light to come on can be the worst thing you can do to your engine. Could you explain why? I kind of thought the purpose of that light was to let us know when the oil is low…I didn’t realize we SHOULDN’T be waiting for the light to come on. I usually get my oil changed every 3,000 or 4,000 miles. I’ve heard that if you play your cards right, though, it’s possible to go almost 10,000 miles between oil changes.

    • CAR FOX February 26, 2015 at 9:28 am - Reply

      Hi Lisa,

      When your low oil light comes on it could mean that your oil pressure is low, or that there’s not enough oil in your engine to keep it properly lubricated. These are both issues that need to be addressed to keep your car in good running order.

      However, it’s important not to confuse the low oil light with an oil life indicator, which you’ll find in many newer cars. If your car is equipped with an oil life indicator, it will notify you when it’s time for an oil change. Hope this helps!

            I disagree sir! The owners manuals are not BS. The manufacture has done it’s due diligence in research to provide optimal performance of your vehicle. If the owners manual says it is safe for your vehicle to travel 7,500 miles between oil changes using conventional oil (if that is what is recommended for your vehicle) and is driven under average conditions then you better bet your bottom dollar it is safe to do so.

      You need to change your oil because it gets dirty. When the oil gets low then there isn’t enough to properly lubricate so the engine parts get too hot. Really you shouldn’t trust the lights anyway they are not all that accurate.

    Car manufacturers are not in the business to help the consumer. All they care about is the warranty period of the car. Once that warranty ends you are stuck with all the repairs. So go 10,000 miles between oil changes, but trade your car in three years.

    Bottom line is this: It all depends on type of vehicle, extreme conditions (cold or hot), and driving habits. If you have a high compression performance car, live in phoenix where temps can be 115 deg, and drive aggressively….you had better change the oil every 3000. However, if you drive a more mainstream standard vehicle, live in a temperate climate like Tennessee, and drive very conservatively….you can go 7000. Double the miles for synthetic. Todays oil and engines have improved dramatically over thru technology. Changing every 3000 miles may make you feel good, but could be a complete waste of money.!!!!

    Conventional oil should be changed at 7500 miles, synthetic at 10000. The level should be checked at least once a month. A new off the lot car should have the oil changed at or below 1000 miles to get all the new friction wear out. I change Trans fluid every 20000 miles.

        Actually, for people that dont drive their cars often, they should use conventional oil instead of synthetic, or a blend. Reason being, conventional oil is thicker so it will take longer for it all to drain down to the pan. The cylinders, bearings and such will stay coated for a longer period of time between long start ups with thicker conventional oil opposed to thinner synthetic oil

    Hi, my name is mike and i have a toyota corolla 1999 with 251,000 miles which i use synthetic oil on, how often do you think i should be doing and oil change?

      I think the factory recommended 7,500 miles between oil changes but don’t know the recommended oil. If you are using a synthetic already, changing it at 7,500 should be fine. If you are really concerned because of some severe driving condition, check the oil by pulling the dipstick out and doing a visual check. If it appears to be pretty dark or almost black, it’s about time to change the oil.

      If you’re using 5W-30 Toyota is going to tell you every 5K.

    I have a 2005 Toyota Highlander with 447,000 miles on original engine and transmission. I change oil according Toyota manual which recommends change at 5,000 miles. The maintenance light at 5,000 miles reminds me but I stay on top of it.

    I now use Full Synthetic oil in my 2007 Prius because it should get twice as many miles (10,000) as regular oil (5,000 miles) before needing a change. Sent a sample of used oil to Blackstone Labs ($28; see online) for analysis to ascertain if this was true.

    Yes, the lab confirmed my sample indicated an oil change was definitely due (and suggested changing a bit sooner next time) …but the oil sample probably had 12,000 miles on it. So 10,000 miles between changes should be fine.

    My Total Base Number (TBN) was 0.9, which is slightly below their cut-off of 1.0. The level of iron in the oil was higher than Universal Average reference data (at a mean of 7800 miles), but all other components/contaminants were substantially below the reference data (ie, they were favorable).

    So I am satisfied that I am good to go with a Full Synthetic Oil change interval of 10,000 miles.

    What if you only drive 1500 miles in six (6) month with short stops and you use full synthetic oil and filter. Should I change it even thought the maintenance minder say you are at 75%, I have heard that you should change your oil every six month or 4000 miles which ever one come first.

    Is it ok to put synethic oil in a car which normally takes conventional oil? Would I have to change my oil less frequently if I use synthetic? Thank you!

    I am a huge, quality Synthetic oil fan for one reason among others. In Canada’s sometimes cold winter climate, I have seen conventional oil at -25C, -15F or colder change to thick molasses.

    I have a 2004 MINI cooper since new. Manufacturer/car service indicator says to use and change Synthetic oil every 24,000km, 15,000 miles but I always diligently changed it and oil filter every 5,000 miles when it was under warranty and every 7,500 miles since. I have 113,000 engine trouble free miles now, changed the Rocker (valve/cam) cover gasket last year and it looked like new in there. Car today doesn’t leak oil, doesn’t burn oil and engine purr’s. I stick to a 7,500 mile synthetic Oil & Filter change schedule for all my cars now.

    I have a 2011 impala. The readout panel says it is time to change the oil. I use synthetic oil. It has not reached the milage on the windshield sticker and it says I still have 2,000 more miles to go before an oil change but the volicity on the readout panel says 0%. ThH oil change place said I can go the 2,000 miles but I’m not so sure.

    You know I get my Synthetic oil online with Walmart on rollback under $23 for five quarts. My filters I get from Fred Meyer or Amazon for under $8. My oil is Mobil 1, Castrol EDGE full synthetic or Valvoline full synthetic which ever is on sale. So combine that with the 99 plus percent filter that is on sale any you have a $30 oil change. I don’t drive that many miles since retiring. So I just change twice a year rather than being cheap. My Toyota Corolla has 108442 miles on it currently. I fully expect to be driving this car when it turns 300,000 miles. Because I can afford the extra cost of $60 a year vs. $30.

    I’m older and I’m retired we don’t drive as much as we used to. But I change my own oil. I switched the car and my diesel truck over to synthetic oil about 60 something K miles. I can do an oil change for under $30 now. I get my Castrol Edge full synthetic online for $22.87 for 5 quarts and my Purolator One 10K filter for $7. I don’t worry much about the mileage. I just wait for a nice day in the October to November time frame and another on in the April to May time frame. The Corolla has nearly 109,000 miles on it now. and its not using oil. I also switch brands of oil what ever is on sale. Sometime I use Mobil One other times I use Valvoline Full Synthetic. I can afford two changes a year. I do the same for my Duramax. It costs me a max of $64 if the oil isn’t on sale. Shell Rotella Full Synthetic 5W-40. I fully expect well over 300,000 miles out of both of these vehicles. So I guess they’ll be wore out in about 2040. That would make me 96. I’m not going to worry that one to much.

    All Car Geeks!!!

    For Conventional Oil change: if you use Penzoil, Castrol, Mobil or Valvolin, use 5K easy, Queaker Stake use 3k.

    Full Syntec/Full Syntec High Mileage: Use 6K or 6500, no more than that.
