Break-In a New Car

break in = bull ****

Think of it like a child. If you baby him 24/7 and overprotect him, he's either going to grow up as a spoiled little brat or a pansy.

Occasionally he needs some tough love.

Thats why my break in period consists of ripping through the gears almost to redline.
Modern cars are built with very fine tolerances, they don't need to get acclimated to anything. These aren't delicate pianos. Why do you think Ferrari runs each car around the Fiorano test track before they send them out to customers? Or why Nissan dynos each R35 GTR motor before they put it in the car and ship it out.
Babying your car only makes it slower! (note this theory is not and most likely can not be supported by concrete evidence, but I don't give a sh!t)

Guys, Im going to tell you that this is a neverending thread, there is no answer to this question. Just lock this thread.

Improper break-in = oil burning problem years later.

That might be taking the baby simile a little too far.

Ferrari engines are hand made.

Nissan Dyno's engines just like any other manufacturer to make sure its up to spec, that doesnt mean you have to beat the crap out of it when you get it.

Whats the point of risking it guys? do a few hundred miles under 4000, then the next few hundred gradually going up to redline till you get to 800-1000 miles. That way everyone is satisfied. Beating the crap out of a car to make it faster sounds a little silly to me. Let everything sit GRADUALLY. Neither the sissys nor the drive it like you stole its are right.

Gradual break in period.

All I can say is that when we bought my wife's 06 350z 6mt, we drove it like we stole it right out of the gate. I wanted to see how it stacked up to my M3 during the test-drive.

When we bought my 06 350z 6mt, I broke it in 100% TO THE LETTER!!!!

Hers still runs perfectly and burns zero oil. I never clean out her tailpipes and they are always always clean

Mine burned a quart of oil every 800 miles. I cleaned out my tailpipes every week and the were black inside by the next week. I traded in my piece of crap 06 for an 07 with the HR engine. I totally disregarded break-in on the 07 and it burns no oil. It also runs very strong.

I am sold on break-in = BS

YMMV...

I always do the break in. Usually 1,000 - 1,500 miles just to have piece of mind.

this argument comes up all the time on car forums and you will have people that tell you oh just drive it like you would normally or you'll make it slow or you need to drive the piss out of it to really break it in

that logic might fine on cars if you were the fonz or something back in the 60's

look its 1200 miles just do it the right way the best you can and forget about it

Wow I didn't know everyone had such strong opinions about this subject. The only reason that I never broke-in my vehicles was because I was too impatient just like SHUMBY. I said "awwww F**k it" I wanted to smile when i drive.

shumby

heheh ya waiting sucks i like instanc gratification.

well in newer cars when you break a car in your not just braking in the engine your bascially breaking everything else in getting it all to work together getting the suspension set and producing friction.

i mean the VQ is a strong engine im sure it would be ok because honestly they dont expect everyone to follow it anyway or even read the manual but i mean you just bought a 35K car why not take a few days to be easy on the car. it says dont go over 4K i mean its not like if you do it once your screwed..... but its common sense dont redline it dont drop the clutch at high rpms dont floor it from a stop.

pretty simple


i mean i hate to bring up the GTR all the time but one of the guys with this mysterious transmission failure the whole world talks about did like almost 30 launch controls on a car with less than 1K miles on it. i think someone said it was like 600 miles....... i mean what do you expect

Ride it hard and leave it wet.

nogoodname

you did break it in......just misunderstood what break in means





I've heard of that too....... maybe we should ask the ppl who dont have oil burning problems with the 03 G Coupes and see what break-in they did.

Are you still talking about cars???
