Break-in period DONE RIGHT!!

[so cal gts 03]

Hi guys, just wondering... how would you guys break your car in CORRECTLY if you guys had the chance??

About at how many miles would you reset ECU? (if you even do that)...

[t2000gts]

just drive conservatively for about 1000 miles. no crazy downshifting, try not to stay at one rpm too long (vary a bit), stay below 60mph and 5000rpm.

If it seems like fun.......... Don't do it. No hard braking, turning, Acelerating or engine reving.

:werd: , and after the 1000miles, get and oil change.

[jdm-style]

when i first got the car i shifted no later than 4000rpm, for about 1500 miles, then i changed the oil out and enjoyed after wards

Um guys the motors should have done been broke in from the factory I believe most motors on cars nowadays are broke in before they are ever put into the car! If TRoyota doesnt do that then O well I am screwed cause the second night I had mine I raced an automatic Mustang GT up to 125mph+ so but then again if rumor holds true the harder you break them in then the harder they will run and the longer they will last LOL dunno how much of that is true but hey!

What are you saying? Use english please. The only punctuation you used were two exclamation points!!

Got my car with 4 miles on the odo. For the first 200 miles I was SUPER easy on it, I would take off real easy, never let the revs go past 4000 and little load as possible. From 200-700miles I started to give it a little more load, then easing off, then a little load, then easing off, but not going over 4500 rpms, I heard rings seat better like this. If you always drive it at a constant rpm during break-in they might not seat correctly, which means NO FREEWAY DRIVING. At about 700 miles or so, my g/f made the dreaded comment no man with a GT-S should ever hear.. "I think your GS-R was faster!" Umm......LETS ROCK! So I dropped the hammer and let her rip, even though I hadn't fully broken her in. =) Needless to say I shut her up. Now 12K miles later, Its running like a charm, even If floor it everywhere, every 3K miles my oil level is exactly at the top line...amazing. My GS-R if driven hard would gulp about a quart or so...

Wow...you guys baby your cars. I got mine and I drove it very agressively during the break in. I've heard so many conflicting stories about driving conservatively vs. pushing it hard. I guess it depends how impatient you are. I hit lift many times during the break in and I lived in the boonies so not driving on the freeway was not an option. I just varied the gears so that I wasn't at the same RPM all the time. My car has 60,000 miles on it and has had no problems at all, and I hope it stays that way. I'm sure most reasonable, level-headed people would say but a diaper on it and treat it like a baby. I put leathers on mine and whipped it and made it my bizzach from day one. Do what makes you feel good.

Have you people ever thought about the fact that these cars are loaded onto something b4 your dealership ever sees the car? They are driven extreamly aggressively to either the loading dock, loading bay, parking lot, whatever, b/c time is always an issue for large industeries.

ALSO, when you test drive a car, do you baby it? Hell no, you see what the hell it has! My car had 14 miles on it when i bought it, which means that at least 3-4 people could have taken that SOB to 7K rpms b4 I ever laid eyes on it. Breaking in a car is pointless now a days.

i dont understand why people have to question the people that R&Ded the car. do what the manual says.

:werd: my friend sent me that link before i got my car and i drove it hard..didnt break it in...

[chameleon]

OK, but this is the big question...

If the break in period is pointless (actually harmful, according to J5ISALIVE's link) why on earth would the manufacture recommend a break in period? Recommending a completely unnecessary break in period makes absolutely no sense what-so-ever.

As far as the above posted link about "the best way to break in a new engine" is concerned, the author's entire theory of why it is beneficial to run a new engine incredibly hard during break in period is based on the assumption that all cylinder walls are steel with a "honed crosshatch pattern" that the piston ring needs to wear into. According to the author, the ring needs use the roughness of the honed steel to mold itself to the cylinder wall before the cylinder wall surface becomes smooth from wear.

So I guess we can just rest assured that the author knows what he is talking about, I'm sure that he's done the necessary research to confirm that every automotive and motorcycle engine on the planet is machined the exact same way...:rolleyes:. On second thought, doesn't the Celica use some thing other than a finely honed steel insert for the cylinder's lining? Celica's cylinders are pure aluminum with an incredibly thin special chemical coating that absolutely does not wear. This makes his entire theory (if it is even correct at all) false when applied to the Celica's engine. Maybe some one should email him in regards to this so he won't inadvertently spread anymore false information thru his articles.

I've heard tons of stories about people beating on their car from day one and still getting a long full life from their engine, so I will at least agree that break in periods are, at the very least, less necessary than they were in the past. However, I will still always perform the break in period exactly how the manufacture describes. Their break in recommendations are coming from the people who designed and put the car that I drive into production. Their recommendation on this matter means more to me than than "the motoman" or the guy next door who tells me he had his Civic up to 100 the first day he bought his car. Just my opinion...

Drive it the way you want it to perform. i.e. accelerate fast (but don't hit lift) and shift fast: get into the higher gears faster. I have broken in 3 cars and 2 motorcycles this way, and they go fairly fast.

My girlfriend, who also drives a Celica, babied her car for the break-in and she notices a difference in acceleration between our cars. She knows my car accelerates faster than hers, so she co-drives my car at the auto-x's :)

1 + 1 = My 2 cents :)

The problem with this is you may have a factory freak motor while your gf my have a weaker motor. No 2 eninges perfrom the same, some my be more powerful than others. ie, some Celicas have a lower baseline dyno that others.

wow... such provokin responses from everyone on the topic... i guess it is a very controversial topic... i agree with cham though... i will follow manf. break in rules... my dealer also told me drive it that way till i hit 1000 but i think that's maybe a little too much... andrew i believe u did that? How many miles have u had on your car so far? Any major engine problems yet?

thanks guys... i've been kinda babyin mine... i don't take it above 5k... nor do i stay over 50... i HAVE gone over 5k a couple times, but for only a few seconds... and i have gone up to 65 a couple times.. like 3 or 4 times... put on 200 miles so far... they gave it to me with 80... dunno how it was driven, but the dealer ASSURED me that the porter who drove my car was a trained professional :rolleyes: Somehow, i doubt that because first thing i noted when i saw my car, the guy who was cleanin it (the porter) was on the phone with his "homie" talkin about some drinking party that night... got in the car, noticed radio was turned up a little high and bumpin power 106... :thumbdown

I feel a little violated... however, i will still take the break in procedures to the extent that the manf. told me to, and then i'll start drivin it hard... then a little harder... then it ought to be broken in...

[Tryan77]

I know factory tolerances on engine parts are better than ever and have been reducing the need for the prescribed break in period. The manufacturer has to know the car will be driven before the "magical" break in point.

I think the bottom line is that engine wear is slightly greater during the initial miles on your car, so they have left the traditional break in requirements/suggestions for the cars.

I could see a few advantages to telling people to go through he entire break in procedure. It might help people become more familiar with their care and less likely to damage it. i.e. mis-shift.

Yes, read the manual, it states what the break in period should be...what I remember is that it will effect the mpg that you get in the car.

[t2000gts]

break-in continues for almost 3000 or more miles. the first 1000 is the brunt of it, which is why the owner's manual says to take it easy. after that, you drive how you want to drive. i drove like a maniac from 1200 to 3000, and the car feels strong to this day (40k).

even if your gf broke it in, she probably didn't run it hard during the extended break-in period, in which case it's still not much of a difference. just beat on it a bit to warm it up.
