Okay so I've been reading up on break-in methods.. And the average break-in method was:

Dont go passed 5k RPM for the first 600-1500 miles

But has anyone read this article?

http://www.mototuneusa.com/break_in_secrets.htm

It's the exact opposite of what the manual states.. It actually makes sense too. But I wanna know if anyone has used this method? Do they regret using this method? How is their car doing now, since they used this break-in method? It makes complete sense.. But I've never heard of it until now.. What do you guys think?

 

if you search, that's one of the most commonly discussed things. some people swear by it and others say the mitsu engineers built it, so follow their instructions. in the end, it's your car, and it'll be a great car no matter what.

 

It has been discussed to death but that article is not one I've seen before.

Personally I'd take the middle ground. Don't redline every gear right from the get-go, but do make sure to let the engine breathe a little by letting the RPM's slowly climb to about 6k.

From my experience there's no danger in this, as long as you don't whomp on it lol Just let the engine "learn" what it can do by letting it reach those higher RPM's slowly and gradually.

 

Really? I really did do a search about this.. and the only thing that was being discussed was the Rev limit in which not to exceed.. Not really the method. I myself have not heard of this method.. Has anyone tried it though?

 

the 'super hyper mega' thread starts with it:

Didn't try it on my evo and wouldn't. What people fail to notice is that the "break-in" this guy did and endorses is for motorcycles. Totally different motors, seals, etc. Not a good idea on a 4-cyl turbo car. But, heh, it's your car. F-it-up if you like. I trust that the Mitsu guys who designed the car would know the best way to break-in their car.

 

that mototune article has been around forever. i dont buy into it.. for a racing machine that will be rebuild often it probably will make more power for the shorter life span, but for longevity, and reliability go by the book.. breaking it in like that is sure to wear the rings a bit more than by the book therefor making the motor spin with slightly less resistance and of course making a little more power. but is a little more power worth having to rebuild sooner rather than later? not for me.

 

well i didnt even read the links but the proper break in is to take the motor through the entire RPM range slowly and smoothly. that means dont launch and dont mash the gas...its just letting the rpms rise and fall...in a controlled fashion, and that also doesnt mean to bounce it off the rev limiter

 

You break your car in the way you would drive it.

 

not always true...you need to let the rings seat

 

not to mention the motoman method was designed using it for streetbike engines. i know of people whoa's evo's burn some oil after not breaking in properly by the manual. i broke mine in properly for 600 miles and it doesn't use a drop between changes with 42K miles on it.

 

I hopes this clear things up about engine break-in period. The Motoman break-in precedures are ONLY for engines that has just been rebuilt. You want the rings to "seat-in" properly for better seal. Now all the companies out there that produces car engines all ready knows this and they already put their engines on a engine dyno to do such that....to have all the internals seat in properly before installing it on the car. Then after installing it in the car, they put the car on a regular dyno to check both engine and drivetrain. After they drive in onto the barge on container to be shipped around the country. Now if you think about it, there is already a little mileage on the motor coming from the engine dyno, regular dyno and the distance they put from the carrier to the barge. Follow the manufactures break in period, they know better.

 

Some say the "break in" is for the tranny, i dont beleive that.....it may partially be for that but clearances in motors when theyre new are tight(not as much in turbocharged cars but still) i broke in my car according to manf. specs and it doesnt burn any noticable amount of oil at all between changes. I kept it easy untill 900-1000 miles w/o hitting redline and trying to keep it under 5000rpms. NOW....is a different story

 

With 4 miles on the car I did a few WOT runs not passing 5k rpms. Then proceded to drive normal like I would drive the car normally for the rest of the cars life.

Still did occasional WOT pulls, but not too much. At 300 miles on the car, is when I redlined it and raced the car. (but i was careful with shifting and never launched it)

Now at 3.5k miles I dont notice any oil consumption, no signs of any problems and I get anywhere from 20-28 MPG city driving. (depending on how I drive) The usual MPG is 24 though.

Good luck on your decision.

 

i def. wasnt easy on the car the 1st day i got it, except for the first 20 miles, then i had some wot pulls and the car feels fine today , with no oil leaks or anything. 35000 miles and goin strong
