How many miles between oil changes

[@microfarmers]

I've been a mechanic for 30 years and I use quality synthetic API SJ or better. 5000 mile oil changes for a light footed medium range driver in a non dusty location is sufficient. I just diagnosed failing lifters and timing chain tensioner due to 10,000 mile change. $4,000 fix vs $40. Fix.

Car manufacturers don't want your car to last 200,000+ miles. It's bad for their bottom line. They want that engine to wear out right after the warranty expires, so they can sell you a new engine or a whole new car. An oil change using top of the line synthetic oil going for $16/quart will cost you around $100.

As a mechanic it depends on your driving conditions. You can go longer on oil changes if you do alot of extended highway driving no longer than 7k-10k miles. If do alot of short trips, in town driving or idle most of the time oil should be change more frequently 3k-5k miles or 6 months whichever comes first. It also depends on what oil brand and filter brand you use. If you use cheap synthetic oil like Super Tech or Quaker State driving in severe conditions 3k miles oil change max. If you use conventional or synthetic blend oil changes are 3k oil change max. Frequently oil changes are way more cheaper than replacing a new engine.

22 years ASE certified here. Change your oil frequently to get the most out of your engine. A good rule of thumb, with synthetic, is 5k miles or 6 months.

Do not listen to automotive corporate recommendations, random internet bots or climate activists. Don't worry about the waste oil affecting the environment, shops recycle oil and for DIYers, you should take the old oil in to be recycled.

Only a professional mechanic with at least a decade of experience with oils, engine teardowns, and seeing the same engine since new go over 300k can tell you like myself. There are so many factors and variables. I can easily tell someone how long they can drive if they tell me their variables and they may not be able to find them out at all like average speed and oil consumption. It's difficult and took me almost a decade of experience and knowledge to be able to have a say. I can prescribe exact time and milage ratings to my customers but only if I have the specifics known. I recommend a customer with a Mitsubishi mirage to drive 15-16k with Pennzoil platinum 10w-30 because I've uoa tested the oil before and I have the variables of her average speed, mpg, and engine and total vehicle specs that attribute to oil wear and also know those Mitsubishi engines on top of that. She's put on almost 110k on it last time it came since new. No oil burning and still clean inside. I'm not worried about her engine at all. That shatco CVT is what is more important and I've changed the fluid on it once and will have to again next time actually.

[@thetechlibrarian]

I totally agree that’s why I think the blanket 10,000 mile oil changes are just too long there’s too many variables for the average customer I’ve seen my oil look totally shot at 4500 miles and I’ve seen it still look pretty honey brown at 6500 it really just depends on your driving

[@anonymike8280]

Very good point. What I think now is that people have to above all consider the type driving they are doing. The driving most people do represents severe duty. They don't want to concede that. Myself, I have a 2001 4cyl Toyota Camry. I use conventional oil and change it at 2500 miles. It's too easy to do on that engine. No one ever did damage to an engine because they changed the oil too soon. Doing it the way I do, I don't have to worry about whether synthetic is better than conventional. Or what kind of driving I'm really doing. Or how long I can wait. I just do it, and I know I always have clean oil in there. My driving undoubtedly qualifies as severe duty. All short trips is severe duty.

Total bull, the local dealers are all franchises and they want you in their shop as much as they can get you there, that way they can try and upsell you services you don't need. I run 10,000 mile oil change intervals in all my engines never had a problem and I only run Redline Group V Ester Based Synthetic oils. The problem is people use these group III petroleum based oils that are labeled as a full synthetic. Group III oils are just hydro cracked which means the oil is put under a higher pressure during the refining process to remove more of the contamination from the oil. The molecules are all different shapes and sizes so the oil wears out quicker than a true Group IV PAO or Group V Ester Synthetic oil. A true synthetic oil every molecule is the same shape and size and that is what allows them to last longer than a group III petroleum oil that is labeled as full synthetic.

I’ve got a 2011 Toyota Camry with 240,000 miles and 10,000 interval changes with 0-20 synthetic. I put both highway and city driving on it and no noticeable oil burn between changes. Car runs like a top as an every day driver. I had doubted the 10,000 mile interval until I researched it. Not saying it is recommended in every case just what my results are. I would also say, nothing at all wrong changing it more often. More often can’t hurt. If I had known I was keeping this car 14 years plus, I might have opted 5,000 interval as I now hope to join the 300,000 mile club with this one. Toyota builds a quality product very capable of running 240,000 and beyond on their recommended interval. I’m not sure about other manufacturers.

Why waste money on needless oil chaneges. The older cars definitely needed to change every 3,000 miles. Newer vehicles are made with a lot tighter specifications and clearances. Not much blow-by to contaminate the oil from the rings etc. Plus the synthetic oil does a lot better job of lubricating and not breaking down with high operating temperatures. The oil simply does not get dirty enough to do any damage on extended oil changes. Just go by the manufacturer's recommendations and your owner's manual and your engine will last a long time.

I tend to agree that if you drive sensibly and in a good climate, changing oil and filters only once a year or every 10,000km won’t cause your engine to self destruct. Modern oils are claimed to be good for 10,000 to 15,000 km. Oil companies wouldn’t risk litigation by having their products implicated in engine failures. So, more frequent oil changes are uneconomic (for the owner, not the workshop). Most vehicles will develop other issues like rust, wiring, cooling, seals and hoses etc around the 12 to 15 year mark that means even long term owners will likely trade them well before the engine dies. As for the latest high tech cars so reliant on computers, we have yet to see how long they last, but I bet it won’t be the engines giving up first for want of an oil change.

If your one thinking your gas powered car can go 10,000 miles between oil changes, you need to ask yourself, How many oil samples have you done from fill to dump. Most cars it will be 7500 miles. But if you own a Kia, you may rue the day their dealers told you 7500 on conventional/synthetic blend oil changes. Theres more that goes into this that I think your overlooking. Your engines pistons will get a little bit of unburned gas passed the rings, this will also carry anything else in the combustion chamber as well back down into the crank case. This is why the manufacturer recomends x amount of miles. Dilution of oil and other contamination in the oil thats cycling through the engine. Theres also the heat fluctuation that reduces the oils viscovity over long periods of time. It dhould always be checked at least 1 time a week, but in most cases i would say do what the dealer/manufacturers recomend. If you own a Kia with a 1.6/2.0/2.0T/2.4, do them around 4500 miles.

Take it from me and I'm sure you will say he's right. I've been changing my own oil for years. Fact is the engines have changed over the years as well. Back in the 80s I did conventional oil changes ever 3 months or 3,000 miles. Oil back then you could buy it at about $1.39 a quart and the filter was about , $1.89 or less. Then the synthetic generation of oils started booming. Then $2.59 a quart and a synthetic grade filter about 2.99 and I started to switch to the synthetic even though I didn't need it. I started seeing a difference in power, gas milage, and a cleaner, smoother , cooler running motor, so I have been using it ever since. I do 2 oil changes a year because I drive about 12,000 miles per year. My engine is still doing great. So I say that's a reasonable amount of time between oil changes, I've never regretted it to this day. If you do that, you, too, will have the same or better results. If you want your oil to look like glue by waiting 1 year, then please proceed to listen to those who want you to blow a motor by saying it's OK going longer. Remember who has to pay for that mistake.

I live in Turkey and in the user manual of my Kia brand vehicle, which I bought in 2013, it is written that I should change the oil every 15,000 km or once a year. However, in the same manual, it defines some situations as difficult conditions and if I use my vehicle in these situations, it reduces this change interval to half, that is, 6,000 km or 6 months. In my country, 90 percent of vehicles are used in these difficult conditions. However, authorized services change the oil at 10,000 or 15,000 km, which also suits the users, and I have not seen a single vehicle that complies with these long change intervals that does not burn oil when it reaches 100,000 km. Most of the vehicles that exceed 100,000 km in my country have serious problems in the engine and burn oil. Oil is cheap, filter is cheap. Watch a few videos on how to do it, buy oil and oil filters from well-known companies and do your own oil change yourself. Short intervals are the best. These programs force you to buy a new car. The modern economy wants to sell new products all the time. Maintenance and repairs do not make their wheels turn. Throw out the old and buy new, they say.
