Wondering what you folks feel about the first oil change on a new car/truck.
 
On my Golf R, I changed the oil and filter at about 1200mi, now every 5-6K while factory recommended is every 10K.

I’ve always changed oil at about 1-2K miles but I think some manufacturers don’t recommend early changes.

If the car is a lease and you don't plan on purchasing, factory changes are perfectly fine. Why spend more than you have to. My usual car life has been 8-10 years but I’m jonesing for a Tesla or similar. More of my coworkers are ordering them. Ugh!

If owned, I follow the instructions whether from the manual or the car itself.

Also, I drive 55/60 mph for the first 500 miles or so.

When I had the Lycoming O-360 in my Grumman Tiger rebuilt the break in was 10 hours with straight mineral oil varying power constantly. For cars I usually change the oil and filter at 1000 miles.
 
I run synthetic blend in my Tahoe. Recommended oil change interval is 7500 miles. I change the oil at the dealership every 5000 miles. I had the first oil change done at 3000 mile.

I’m one to also follow the manufacturer’s recommendation/manual. I know many do their first oil service earlier, especially for the longer synthetic oil stints.

I do remember when I had a new Accord, Honda specifically stated they put an additive in the first round of oil that comes from the factory that is designed for new car break-in. So premature 1st service was advised against.

I follow Manufacturer recommendations. Needless to say, dealers want you to change oil more frequently than what manufacturers recommend (I see a money motive there).
Many manufacturers use synthetic oil. Their engines are designed with that in mind. 10k oil change recommendations are not unusual with those engines.
Of course usage is a factor. City versus highway, heavy loads etc.
 
For me, changeover to synthetic at 500 miles. Then change oil & filter every 3000 miles.

Of course, this is for cars I own outright. Never leased one.
 
Mahalo for all the feedback.

FYI, the vehicle is a 2019 Toyota RAV 4.

At 5000 miles Toyota recommends:

Inspect /Adjust All Fluid Levels
or
Replace Engine Oil And Oil Filter under the following conditions:

Driving while towing, using a car-top carrier, or heavy vehicle loading
Repeated trips of less than five miles in temperatures below 32 F/ 0 C
Driving on dirt/dusty/muddy roads or on roads with melted snow
Extensive idling and/or low speed driving for long distances such as police, taxi or door to door delivery service

I'll probably change over to synthetic oil when I hit 1500 miles.
 
Following the manufacturer's suggestions for oil and new break-in is likely the right thing.

I have found with new cars that I've purchased, that about the best thing you can do is to take a 500+ mile road trip first thing at highway speeds (55-65mph). This helps break in all the parts and seals and will add to the long-term life of the vehicle overall. Conversely, driving a new car only to the grocery store down the street 50 times over several months does not help the same.
 
My ‘17 C7 GrandSport came with break in oil which was required to be changed out after 500 miles. I don’t know exactly what they used but I suspect it was higher than normal in certain metals. After that change it only gets Mobil 1 every year or sooner if I take it to the track. That has been at less than 3000 miles.
 
I am switching over to a new independent shop where the owner recommend oil change every 6 months regardless of the usage. his argument - if you pour a brand new synthetic oil to a container and leave it there untouched for 6 months, this oil will turn acidic, so much more will be the oil in the engine. he said acidic anything is not good for the vehicle.

this is the first time I heard this argument..

I normally change oil in my daily driver at 10,000 kms, manuals says 15k while the dealer says 8k..

This is the worst thing u can do with a new motor....U need to VARY the load and RPM's a lot especially durning the first 500 miles..Constant highway driving does the exact opposite....
 
With the short first oil change, GM must be either adding a break-in additive or using a break-in oil....or there is a ton of crap inside their new dry sump motors. Probably the oil.....

I always heard that the short oil change is to eliminate/remove metallic debris resulting from engine break in.
