What!!! Where did you hear that piece of myth? Go ahead if you want, and make the oil producers richer. Just change it when the MM says to, or say 20%. It is a fact that Honda puts additional Moly additives in the oil from the factory and they recommend changing it when the MM indicates.Are you supposed to change the oil at 20 miles and 100 miles? I've read you're supposed to do that with a brand new vehicle?
That sums it up nicely!My break-in approach can be summed up as: Don't drive like an idiot and don't go for a long road trip with the cruise droning away at a constant speed for hours for the first 1k miles.
You are fine, just drive normally as you would anyway.Should I make an effort to cruise the highway at 55-70mph once a week? I don't want to hurt my new baby,
True, That! ^^^Nowadays, with modern engines, the break in just isn't as critical as it was in the old days.
OK, so my last question is... how many miles, or how long of a time, is a typical break-in period? I go 6 months between oil changes when I use synthetic oil since I don't put on that many miles per year. Is the factory oil meant to go 6 months?You are fine, just drive normally as you would anyway. Don't overthink this.
The factory oil is meant to go until the maintenance minder tells you to change it (or up to the maximum of a year, I believe -- it should say in the owners manual).OK, so my last question is... how many miles, or how long of a time, is a typical break-in period?

I don't think that causes harm as it is not mentioned in the manual, the manual just wants you to avoid sudden acceleration or braking, which makes sense. Building up speed gradually shouldn't be harmful. I really don't know why constant speeds would be an issue - if you think it would then maybe you could vary your speed so that it is not constant. 10 minutes at 75, 10 minutes at 70, 10 minutes at 65 in the slow lane. Exit a few times and re-enter. Your drive will be a little longer but at least you get to vary it up. I don't think constant speeds is harmful but I don't know the technicalities either, I just follow the Owner's Manual.I've got a 2017 EX that the dealership is driving in from about 68 miles out. The interstate here is about 75mph speed limit.. Will it be an issue for the vehicle if it is driven for ~1 hour at around 75mph while under the 600 miles?
