Break-in

I’m not going to die on a hill here. Do what you please. This is just my suggestion to follow the manual.

Your 10k rated oil is not going to oxidize right at 10k or less. There’s no need to change it earlier, even if there’s particulate in the oil. Just my 2 cents.

If you’re having that much worry about break in particulate in your oil it’s not going to be an oil problem lol.

Here is some great advice from a Toyota engineer.

David was a production engineer who conducted evaluations and supply chain monitoring and consulting. He is not a chemical engineer or automotive engineer specializing in engines. Albeit, he is a great resource on YouTube, but he's not a be all end all. Like my peers here, he recommend shorter oil change intervals. That's totally fine to do, but if someone can show me data to back why the V35A-FTS engine needs shorter oil change intervals than what it says in the manual, I'm not convinced.
 


Some more great info from this guy.

"It's not because I'm smarter than Toyota, it's because we have different objectives." - that's a great statement.

Critmonkey, point here is not every service interval but just that first 'break-in' interval as that's the topic of this thread. An interval from 80k-90k is not the same as 0-10k.
Can the engine handle it? Yeah, but if I want to get 250,000 miles out of it and pass it down to my kids I'm going to do what I can to help that.

Auto manufacturers design to get through the warranty. They aren't concerned with what happens after that.

The manual doesn't say wash and wax the paint, or store indoors, but yes, that will also help prolong the life of the vehicle.
 
Not GX related, but back in my Texas Highway Patrol days, when we'd pick up a new patrol car in Austin, we were told to break it in like it was going to be driven. So we would take them to 120+ numerous times on the 200 mile trip home. Those cars get driven hard and idled for days. Didn't seem to hurt them.
 
This is the way we would break in a diesel tractor on our farm in Kansas growing up. (Per my Dad who was a "dumb farmer" with a college education from KU and a air force pilot in WWII, (Captain) I know a diesel is different than a gas engine but I do believe the "hard break-in" did help with the overall performance and longevity. I've done it with our 2010 Limited 4Runner and it has done very well at 272,000 miles with no issues.
 
Does anyone know how to reduce the amount of engine braking when letting off the accelerator? When on the highway and you want to coast, it often aggressively engine brakes (activating rear lights). It makes me nervous, since it can be strong, but also looks like I am brake checking people behind me for no reason. Is there any tricks to changing the level?

I think that is one of the safety features that can be turned off. My wife commented on it today.
 
Manual is available online. Resources
