I just got my new is a few days ago. Following the advice of my friend who owns a BMW I have not run the car very hard. I hit the red line once or twice but nothing more. I try to keep it under 60. Is there a break in period like the bmw's for the new is ?

actually if you read the manual it says there is no break in, unlike bmw

but if you want, just drive it easy for the first 500 to 1000 miles, and varies the rpm often. that will help

i dont think you should redline at all when your car is that new, i didn;t try redline until 1000 miles.

I agree with NINEZeRo you should not be redlining your car if its still new.

I think the manual says not to drive it to hard and avoid making sudden stops for the first 1000Kilometers. Wow you can keep it below 60, it was hard for me to try to keep it below 80.

i suppose you can rev it to midrange rpms during the first 1000 miles but I wouldnt redline it, I wouldnt baby it either

I think break in is overrated.

just drive like a NORMAL person for the first couple hundred miles to help all the bearings seat and then DRIVE the car.

how the heck do you avoid making sudden stops?

mcfly

Bearings don't "seat"....

Just read your manual. There are a few guidelines there.

Its a real interesting change for me. Moving from a gx and a landcruiser to a responsive car like the is. Im still aclamating to the responsive breaking and acceleration.

Actually, my manual says 651 miles as the break-in period. (As someone else posted here a while back, 651 mi.=1,000 km, so the number is not as random as it sounds.)

My theory is that if you mostly drive a new car in city traffic, you are almost automatically going to follow recommended break-in procedure--i.e., varying speeds/rpm, not pushing it too hard to drive at excessively high speeds. In my case, I got my IS350from a dealer 200 miles from home, so I had to resist the temptation to set the cruise control on the drive home and consciously vary my speeds.

Engine break-in is a controversial subject. My philosophy is that it couldn't hurt and it might help, so you might as well do it. It costs you nothing, and you can let 'er rip after the period is up.

I am at 650 miles right now and the car feels a bit more responsive and easier to accelerate.
I have not taken my car over 3000 RPM's and over 75mph at all.

I think I am going to keep it up until I hit 1000 miles.

Obviously if youre leasing - there is no breakin

Bichon

Not true. The break-in period of 1,000 km (621 miles) is specified; during that period you are advised to vary your speeds and avoid sudden acceleration.

(Dang, I thought you moderators never made mistakes. )

interesting

I realize this is an old thread. I've been taking it easy since I'm still under 700 miles. When varying the speed/rpm, what is the recommended variation? As long as there's a change? Also, how long can I stay on a constant speed/rpm before I should change. One more, how long do you wait after first startup? Just start and go?

I agree, I haven't redlined mine, but I drove it the first day just like I would if I had for a year. The majority of us probably don't have a car long enough for it to matter.

I don't know, if the idiot in front of you stops suddenly, what are you supposed to do rear end him .
