ok so guys i just got my brand new evo IX about a week ago. already put 750 miles on it. I have been driving it very VERY hard. already redlined on numerous occasions. newayz a lot of ppl r telling me that i have damaged my engine by breaking it in hard. i was wondering is anyone out there who took the "hard break in" approach like i did? and with what results? thanks

 

i did that with a tiburon and by 20k miles it was knocking lol i wouldnt do it anymore

 

do you know that all of that is a myth. i have heard that you should take it ez for the first 500 miles, but have heard that it realy does not matter. i have had friends that are huge rench heads just destroy engines with proper break in, and when they have rebuilt them, just 100 miles later have it on a dyno tunning it, and that engine lasted till this day, and that way 3 years ago. so i guess it just depends all on luck.

 

I bought mine used so I can't speak from experience but I would say that you should have asked this question before you decided to break it in hard like that.

 

The owners manual is pretty clear what to do for the new engine and it is only for 600 miles why risk it. I broke mine in per the manual and I am sure I will have many happy miles of driving ahead. Did you damage the engine only time will tell and even then no one could be completely sure.

 

i thought a rough break in on evo's meant oil leaks...
i have 296 break in miles thus far...sub-3500 rpm shifting and varying speeds...
although i agree there are two schools of thought on breaking in a motor - some say a motor is tested hard before coming to us in the car...

my one cent.

 

why do i see in the near future a post from this guy saying "Mitsubishi is screwing me and wont fix my car"

 

I broke mine easy and it doesn't burn any oil. It only burned a little bit before my first oil change, but I guess that was normal.

 

The school of hard break-in is on race engines. If you do a search on google all of the proponents of hard break-in are motorcycle racers and race teams. For a street driven car that won't be rebuilt once a season then I would suggest following the manufacturers recommendations

take it easy there boy, do as everyone else recommend and break her in nce and easy.

 

This is not much of a comparison, but somewhat works.

At our work we have a fleet of 20+ Chevy Cavaliers. All purchased new and most have around 250k miles on them. The ones broke in hard, ie WOT from the lot, have been the most problem free and run the best. (yes you can tell which cars where broken in hard and which were babied). I have always been a believer in drive it hard from day one,and changing the oil at 1k miles.

 

I broke my EVO in real hard as well... and at the same time switched to conventional 10W30 motor oil the minute I got home from the dealer lot....

I broke the car in hard for the first 5000 miles on conventional oil, afterwards I went back to synthetic

 

Hmm......i did not change my motor oil.....and so I am in a different boat since ive been running it hard on the factory synthetic oil.......

btw i plan on changing the oil at 1k miles.....any suggestions on this?

 

i think he'll be fine yah joyks
