Hello.
Sorry, I decided to get the Infiniti G37 instead of the Acura....
The car is 150 miles away from my house. I either pick it up or have it delivered to my house.
If i pick it up, how fast can I drive on the break in period? Is it good to drive on hwy on break in period?

thanks.

Other people will speak up, but I heard it is not good to drive one speed for a long amount of time. Try to vary the speeds you drive and stay away from cruise control, then you should be fine.

I think when you pick your car up, the dealership will be able to tell you. Also it shouldn't matter at all weither you drive on the highway in the break-in period. It's usually to not go passed a certain rpm range like 4.5 or 5k+ depending on make and model.

In other words, don't redline your gears.

Drive under for a while then over etc.

You mainly just want to stay away from flooring it etc. Just pretend you're an old lady for a while while varying your speeds.

Most engines now adays are fairly broken in from the factory, however, still should be treated gingerly for a little while. When buying a new car I usually take it easy until the first oil change.

Take the advice above. Also, do not rev too high and you'll be good.

Powerbreak it, do neutral dumps, redline it every chance you get...it's under warranty

Seriously, drive like a grandma, vary your speed and gear and you'll be fine.

Thanks all.
I can't believe it, saleman know nothing. don't know anything about break in period. Finally he open the owner manual and told me "don't red line it, don't use cruise control for long period" that is it. The rest are just drive the way you are driving.

Thanks guys.

There are many varying opinions on engine break-in periods on today's new cars. As JB mentioned, the machining and tolerances of today's engines are extremely precise and break-in occurs much quickly than it did in engines of the past.

Basically, don't exceed the manufacturer's recommended rpm for the break-in period. Many times this is listed in the owner's manual (surprisingly). If not, then don't venture into the higher rev range for a few hundred miles. Drive the car gently without being overly aggressive. Don't baby it either, but use your best judgement. If you are driving it for a prolonged period on the highway, vary your speed as much as you can. Slow down and accelerate, drop it into a lower gear and and maintain your current speed from time to time. Stop the car once or twice, let it cool down, and then continue. Heat cycling on a new engine is a good thing.

Again, exercise proper judgement, and you won't have a problem.

If varying speeds helps, maybe try to find back roads/country highways for at least some of the trip back.
You'll get a good feel for the car and can see some interesting things....depending on where you live.

What makes you think that a car salesman is knowledgeable about cars? Many times, that is not the case at all.

If you cannot vary your speed much, vary your gear selection about every 10 miles. This will serve two purposes. 1) It will force the engine to operate at varying RPMs. 2) It will exercise your transmission at differing speeds.

Also, avoid any hard stops.

In other words keep your eyes peeled for a good place to eat on the way back.

Ah yeah, great point. Do a search on bedding brakes. Really helps with rotor longevity.

Break in periods no days are smaller and less important as in the older days (engines are built with better materials and much tighter tolerances) Just vary your speed and rpm. for a little while and all will be fine. Just dont go to the drag strip 10 miles down the road.

teranfon

Yep. Could be a nice road trip.

to most of above advice.

Back roads & two-lanes > freeways/highways
Vary speeds ("But officer, the break-in period requires driving for 8-10 minutes at 40 mph, then 65 mph, then 83 mph, then 107 mph..." ) and check the manual for the RPM you shouldn't exceed.
Use the brakes gently and normally-- don't worry about "bedding" them with a new car.

Heck, it's only 150 miles-- make it a four-hour+ trip if there is someplace you've always wanted to stop by, and take pleasant company.

Sooner hopefully than later you will learn that car salesmen generally know very little about the product they are selling.

do a maximum speed run.

Yup that's the same reason I max on chest press very first thing.
