I'm curious what interval everyone is changing their oil at, assuming we're all using synthetic and not conventional oil

 

I plan to do my first oil change at 1,000 miles and then every 5,000 miles. I can't imagine waiting until 21,000 miles to change oil.

 

I do mine every 5,000 miles.

 

Just did my first at 3,000 and plan every 5,000 thereafter.

 

10k or every year is my plan. Car is 3 years old and thus mine has had 3 oil changes in 3 years.

 

I don’t drive a ton of miles (currently) so I do it annually which is about 5-6,000 miles so far (only two oil changes since new).

I should add, when my annual mileage increases I will still aim for 12 month / 10-12,000 interval. Can’t see going beyond that

 

I did my 1st change at 1,000 miles then at 2,000 miles...and averaged between 5,000 and 7,000 miles now between changes. Currently at about 66,000 miles on my 2022 110 P300. BTW I do my own oil changes.

 

Every 5k along with 5 wheel tire rotation, wearing very evenly @ 26k... great chance to give the wheel barrels a good cleaning and inspect the brake hardware as well.

 

Every 10k miles for me. I get an oil analysis done and it seems to support the interval. I'd not be comfortable going longer based on the numbers.

I'm approaching the end of my warranty at 47000 miles.

I also do them myself, along with the usual routine stuff like, air/cabin/oil filters, brake flushes, tire rotations/swap etc.

 

I did my first @ 3,500 miles and plan to do every 7,500. I was only able to suck out ~80% of the oil...supposedly that is a known issue others have experienced
