Break In Period Procedure [Mileage / Recommendations] for 2025+ 4Runner 6th Gen ⚙️

[The_Dark_Knight_Forever]

I just did an 800 mile road trip with only 90 miles on the Odometer. After a few hours my foot was getting tired so I tried out the cruise control, remembering that a continuous speed helps het better gas mileage and that was something I was interested in boosting on the highway.

Well, let me say "don't use cruise control" wouldn't apply in this situation. If there are any cars in front of you or moderate traffic, that thing is going up and down through the gears and breaking itself in better than I could if I tried. I was actually annoyed with all the gear searching and sometimes aggressive throttle at first but it seems I may be in good shape.

Give the cruise control a try and you will see what I mean.

So are you saying that the cruise control was helpful with your break in period?

I didn't know it at the time because my normal break-in procedure is to just, take it easy, within reason for the first 1K miles. I've only ever owned one brand new vehicle. It was a 2016 Mustang that had 147K miles on it and ran amazingly, but I had to trade it in due to hail damage.

After reading this thread, I feel like the adaptive cruise control pretty much took care of a lot of the recommended steps. Lots of up and downshifting, some engine braking and incredibly varied throttle and RPM's. Time will tell, but I am pretty satisfied.

That's reassuring to me particularly because I drove mine home from the dealership 243 miles mostly highway & I used ACC most of the way. I've been concerned because I didn't realize at the time what a proper break in procedure consists of. This is my first brand new vehicle & I didn't think much about researching the break in procedure. Mine still only has 257 miles on it currently so I've got a ways to go before it the break in period is over.

I worried about the same thing (or similar) with the Mustang cause when I drove it home from the dealer with 13 miles on it, hour long drive, I got a bit "spirited" and revved it up quite a bit. No WoT but pretty darned close. I went all over the Mustang 6G forums asking if I did something stupid to my engine and got mixed responses, but I swear that engine was just as strong at 147K miles as day 1. Better even. I think it's more important to ALWAYS use a high quality synthetic oil, and run the correct viscosity for the climate you live in. Example, the Mustang called for 5W 20 synthetic blend with a 10K change interval. My first oil change was at 300 miles, 5W 30 full synthetic and my intervals were 3-5K miles. People don't realize that the right oil, changed at the right interval is the #1 way to prolong the life of an engine. Spend a little more on oil changes and reap the benefits of insanely long engine life.

I agree...oil changes are the #1 way to extend engine life & minimize problems.
I live in Houston, TX...only about 177 miles from Georgetown, TX. Our new 4Runners call for 0W-20 motor oil. What's your opinion on using that in our climate?

Also in Texas, and Toyota designed it for the 0W-20 and they've tested it and having 100's of thousands of these engines on various platforms.... I think we're good.

I’m approaching 1000 miles I did the hard break in!!
A lot of high speed runs to maybe 85-90 but RPMs never hit over 4000, I also used to tow/haul mode that way there’s a lot of engine braking happened causing back pressure on the piston rings. And on the highway just varying speeds from 65 to 85 to 65 to 85. Now that the motors broken in and needs an oil change. I feel like that transmission had a good break in also and I feel like that oil needs to be drained and refilled.

I'm purchasing out of state and it'll be roughly a 6 HR drive back home. Should I be concerned about the following point?

-Do not drive at a constant speed for extended period

I just purchased from out of state and had a 250 mile drive back. I found a slower way to go, would change speeds a lot, and followed the basic rules. Who knows if I did it completely right but I definitely took it easy. I was fortunate to be in the middle of nowhere a bit so that helped.
