what is everyone's standard rule for break-in period driving?

So far I have 570 mile on the new G and haven't revved aboved 4K and have tried to keep top speed around 60-70mph. Plan on doing this for the first 2.5K miles.

Sound about right?

 

Generally the brek-in period is 3,000 miles. I couldn't help it when I got mine, and I gunned it a couple of times before I hit that mark.

 

yeah 3K might be even better, safer, but as far and the top speed and top rev, does it sound about right?

Granted, there has been once or twice the rev has gone higher but only briefly and certainly not from any hotdogging, just necessary maybe two or three times.

 

Top speed should be alright considering if you have to go on the highway you can't be doing 50 (depends on location). Your good to go. Once you hit 3000 let her rip.

 

Keep it easy for the first 1000 to 1200 miles... like keeping it under 4K rpms... also fluctuate speeds and rpms if driving for long.

I did the above for my cars breakin period... 3k to me seems to be too high for a breakin period.

 

i did 1200 mi under 4k rpm, no extended highway driving

 

+1....1200 is what I do.....that's what Nissan recommends....

my break in period was 1200 (that's wat it says on the car manual)..

 

For me the break-in was immediate. I know there is still some debate as to whether or not you should break an engine in. On the contrary, I have actually read that gunning your engine and driving hard from the beginning may actually be good for the engine.

Either way, I didn't follow a break in period, per se. I would say for the first 1500 miles i drove it mostly hard. I'm at 12k now and can't say I've had anything bad happen to the car besides the fact I get crappy mileage in (NY) city driving.

I would say I broke 100 mph in my car the same night I got it on an open stretch of highway. The car runs so strong now I can't imagine anything bad happened from skipping the supposed "break-in" period.

 

there we go again with the power break ins. I DO NOT RECOMMEND. Just drive 1200 miles and then change the oil and drive up to 3000 change oil then your free to go =)

 

My dealership is about six blocks from the freeway.
From then on I drove it like I normally would 60
to 70 mph all the way home. Checked my oil level
the next a.m. and continued driving normally. I
changed to synthetic Mobil 1 at 1K and have had no
oil useage issues then or since.........Love the car!

 

Has anyone here experienced any negative impact from a hard break-in? And I am talking about tangible evidence or proof that demonstrated damage caused by a hard break-in. I feel like most of it is speculation - understandably so but not necessarily warranted by any fact.

Seems more like a "better safe than sorry" type of policy.

 

The reason why an engine has to break in is for the ring to settle blah blah blah. I guess most people know that so I will not go on with that. My main concerns are, when a new engine runs, 100% creates metal shaving, thats why you need to change your oil and filter around 1200 miles and also again at 3000 miles and yes your RINGS ARE HURTING THE CYLINDER WALLS. Power breaking will cause more damage because when you go by milage, a car driven 1200 miles around 3-4krpm and a car driven 7k rpm, I would say person who rev up 7k damaged the engine more due to over working the engine thus creating more metal shavings.Technically speaking your engine breaks in around 20k miles. Around those milage you'll notice a slight better fuel economy and improved power. Talking about oil changes DO NOT GO WITH 3000 mile and 3 months standard and NEVER USE THOSE 10k+mile oils(A good oil filter only lasts about 5000 miles) Always check your fluid levels and condition once every 2 weeks. It all depends on how you drive. If you dog your car, your going to pay the price.

 

Would be difficult to actaully map the issue to hard break in... if any issues, if at all would arise 3-4 yrs into ownership of the car... and at that time its almost impossible to assess that the issue might have been caused due to hard breakin procedures...

to keep it simple... just follow what every manual for any car says.... "first 1200 miles take it easy"

 

Oh and JBKFizzle45 if you can tell me why engine builds up sludge or oil burn offs, then you'll get some kind of idea why I wouldn't recommend it. Oh and if you pay me, I WOULD BE GLAD TO TEAR DOWN YOUR ENGINE AND SHOW YOU I'll put back everything the way it was.
