Does a new car need to change the original engine oil every 1000 miles?

I don't know what kind of engine oil is installed in the new car. If you have to wait until 7500 miles, I believe it will not be driven for a year.

hey OP, why don't you send in an oil sample to Blackstone for analysis instead of guessing whether you need to do more frequent oil changes? What's the point of posting a picture of a used filter?


on a somewhat related note, I changed the oil on my Genesis GV70 at 1300 miles. I did find metal shavings at the bottom of the oil filter housing, so as others have said, there is still a break in period even with today's better engineering tolerances.
In urban traffic conditions, 7,500 miles does not exist at all. There is no need to ask for a laboratory report for $40. The results are the same. The new oil is replaced, which is obviously quieter and the acceleration response is much more sensitive.

So agree with that. Until all the moving parts polish each other you’re going to have some metal grit of some sort. My first oil change was 1500 miles then every 5000 miles thereafter. Still can’t bit on the 7500 mile change.

I did my first oil change at 1500, sent in a sample for testing and all was good. I will replace filters at 5k and the oil at 11k like I do with all of my cars. I do an oil analysis on all of my vehicles once every second oil change. If there are issues I adjust my changes accordingly.
Are your dealerships doing this early oil changes at 1000 and 1500 miles? My dealership says they won't service mine until 7500 mile, and no sooner. I now have 4000 miles on the odometer.

I don't think any dealerships will do a 1k first oil change since the factory won't cover that under the free service contract. I do my own oil changes and while my 2020 Limited came with the 3 years of "free" service, I never took it in for it.

you saying you tried to delete my post? why, do you find it offensive? I asked a legitimate question and offered a true more scientific approach to this oil change debate rather than someone saying "my oil looks dirty" or, now, the engine sounds smoother after an oil change so it must have been necessary?

Seems like the schedule says change every 7500 miles. And the manufacturer covers/warrants the vehicle based on the schedule. So if the engine fails, they would have to replace it. So not sure changing the oil sooner is really something I need to do. Especially if the oil change is done improperly by me or whoever I might take it to.
My reading of the oil change requirements says "Unless you are a saint, eat a proper diet and only drive on Kansas flat recently paved highways at the speed limit without a full load, follow the severe service requirement of 3,750 miles."

Good job on reading between the lines 👍

No, i made a smart ass remark about the OP who seems fixated on oil. And though better of it, it had nothing to do with your post.

Modern oils don't need to be changed more than every 6000 miles. Consumer Reports even essentially proved this way back in 1996 Two-Year, N.Y. Taxi Test Proves Motor Oils Alike, Magazine Says | The Seattle Times. Oil was at best API SJ back then. Oil has improved substantially since then.
Comparing New York taxis to the average non professional driver is like comparing apples to avocados. Taxis are driven constantly, hours at a time every day. They can get that 6,000 miles in just a few weeks if that long. Our cars might run 12 hours a day on a road trip not every day.

GDI injection tends to dilute the oil with gasoline. Unless you are driving 30 or more miles at a time on the highway on most outings, or check your oil at every fill up it is best to follow the extreme service schedule for oil changes, 3,750 to 4,000 miles and at least annually. My opinion, I follow on my cars, I hope I never have to go through one of those oil consumption tests because I let my engine run dry.
I still regularly check the oil levels.

I wonder what schedule large fleet owners use, like rentals, governments. I doubt they would be overly eager to do more than absolutely necessary.

they don’t care!! Government fleet uses your money so they don’t care. Rentals trade off every other year so they don’t care. Never buy a used fleet car. They only keep them for a short time so preventive maintenance is not on their list of things to do. Just make money and dump them before they start giving them trouble.
I used to service a lot of PHH and Consolidated Leasing fleet cars. Large companies and state government used those companies to manage the maintenance on the fleet. Both gave coupons for 3,000 mile interval oil changes up to 2002 when i sold my garage. I don't know what changes, if any, have been implemented in the interceeding years.
