First oil change mileage

[ish]

At what mileage are you doing your first oil change? If you are switching to synthetic, which oil change or mileage are you doing it at?

When I have new engines, I heat cycle them a few times, and then change the oil / filter. Then I drive for 30-60 minutes and change the oil / filter. Then after 500-1000 I change oil/filter. Then every few thousand miles for the first 10K miles. After that I go 3K miles for life. I use regular oil during the break in process, and switch to full synthetic after I have reached the factory recommended break in mileage / hours. I always try to change the oil more than recommended during the break in process. 

 

I also vary the speed / RPM's, limit the load, limit the RPM's and other stuff for a certain period of time as recommended by engine factories and engine re-builders.

1800 miles on the 6.2.....

whenever the oil life monitor tells me it's time. ...normally around 7,000 miles.

500 miles then whatever the factory says. Synthetic from day 1.

Change at 500 miles both oil and filter, then change again at 1500 miles, then at 3000 miles.  From there I start to take used oil samples and see how far I can extend my drain intervals. 

 

Like on our 2016 Suburban. The UOA's show I'm good at 15k miles so that is when I change my oil.  I use AMSOIL Signature Series 0w-20 and AMSOIL filters.

Changed mine at 700 miles. Will change again at 3000 then go to normal OCI. This worked well on a number of previous trucks

5,000 on oem oil & change to  AMSOIL 0W-20+Filter. 15,000 miles intervals, currently have 16,500 miles.  No make-up oil required. 

 

Ps-have done 15,000 miles OCI for over 25+ yrs.

With my ‘16, I did the first oil change at 3k mi.  I switched to Pennzoil Platinum synthetic 0w20. Some guys switch to synthetic immediately but I like to run the factory oil a while to break in the engine. Piston rings sometimes won’t seat correctly using synthetic oil because it lubricates so well.
