Before we even get started, I'm fully aware of how good modern oils are, how great modern engines are, and all the manufacturer's recommendations for oil change intervals and how none of them put anything in writing about dumping the factory fill before the recommended maintenance interval.
I've got a new 2019 Highlander, just hit 1,000 miles. It's 6-1/2 weeks old, got it with 3 miles on it, nobody but us has sat in it or driven it. It's had an early life of mostly 5-15 mile trips at 35-65 MPH on "country" 2-lane roads (highest speeds) and large suburban 4-lane roads (slowest speeds.... funny, huh?).
I'm not a worshipper of the 10k mile OCI, especially with Toyota and 0W20 oils. I've had Toyotas (5.7L V8s) for the last 5 years, one from new, well it had 2500 miles on it and the other bought at 79,000 miles. Both use oil, the 2014 Tundra bought new will use ~1 quart per 4-5k miles, the Sequoia will use 2-3 quarts over 7k miles. I had outstanding UOA and service from my previous Hondas running 10-13k miles on Mobil 1 5W20, I just don't see it with the Toyotas.
The reason we bought new on the Highlander is I couldn't find a late model used specimen with evidence of an oil change before 10,000 miles. I feel that hardly anyone/s driving pattern meets Toyota's "normal" driving standard. Most people fall into Severe but the service departments choose not to advise people of this because of the TCO marketing scam that the manufacturers are running on today.
Ok, with all that gobly-gook said, who agrees with me to go ahead and drop the factory fill soon, then run to 4k miles for the 2nd oil change and then start doing 5-6k mile OCIs on this?
Thanks
