Not a good idea, it's best to put 3k or more on a car before changing the oil, especially one with synthetic oil. It's believed there are additives in the oil to help the car break in and you don't want to prematurely remove them.

 

i disagree. i strongly suggest changing the oil after break in.

 

I think you are all wrong.. just my 2cents.. I drove my EVO like i stole it from the moment i bought it.. in fact 2 days after owning it i pulled a 30 yard all-wheel drift right up to the dealership.. (before you start flaming it was an empty road).. Anyhow I didnt wait a minute to beat the tar out of my evo... And ya know the funny thing is that it runs great.. it puts down 12.8 in the 1/4 with a 60ft of 1.87. I dunno not saying you guys are wrong to do it just that I believe in braking them in hard.. When I build a motor from pan up I usually dont put a single mile on them.. they get broken in right on the dyno...

again feel free to flame as I'm sure you will .. just my two cents

 

I recommend not beating on it after 600 miles. I increase RPMs to 5500 after 600 miles, 6000 after 700, 6500 after 800, 7000 after 900, then after 1000 I let it rip. On my 2.3 build I changed the non-synth oil after 150 miles, then changed the Mobil 1 10-30 after 1000. I kept boost at 10-15 psi peak until 600 miles, then under 21 psi until 1000 miles.

Next 2 free oil changes will be at 3000 mile (oil life) intervals thanks to my service plan (17000 and 20000 mile odometer)

 

you and your 2 cents.

with a hand built motor, i would normally agree with the hard break in procedure. one of the theories behind that concept is that the extra pressure in the cylinder will allow the rings to push harder against the cylinder wall. this push is caused by the gap in the piston ring, where the gases are trying to escape from the side.

now, for the evo 8 motor, i can see where hard break in can work. why? because its a standard 2 ring setup up (a third one for oil). so what about the evo 9 motor with the single GAPLESS piston rings????

your motor might run fine now, but you might be having excessive blow by and a lot of oil burning.

 

I got my IX the beginning of Feb and just finished break in this weekend.

 

i drive around 180 miles everyday commuting to school and back and business.

where do you live in california? i'll help you break your car in. i'll be good, i promise

seriously

 

Definitely break in the car, because the piston rings have to set. These engines burn oil like crazy if you don't break them properly, it will burn excessive oil.

Go for the long drive, but just keep at low revs like the manual says. Porsche has a 1200 mile break in period.That is just some food for thought. Congrats on the new ride

 

yea see when i got mine a good rule of thumb......and this is rather important!!!.....constantly vary the rpm from about 3 to 4 grand, especially for the first 1,000 miles you gotta understand that the internals are ALL new so of course there will be burrs that will need to be elininated and that just comes with those first 1,000 miles, your will notice a VERY silverish color when you first change your oil.....NOW imagine if you ran your car hard.....i know your still on mobile one FULL synthetic, which is the best there is in my opionion BUT if those little burrs get inbetween critical components like say your cam bearings or on the crank they will cause long term problems.....you wont notice it at first but say afounr the 20,000 mile marker you might get some issues such as crankshaft wobble, VERY BADD STUFF, anyways i know its very tempting to just haul ***** and see what your evo can do on the open road but just break it in properly first so you know you will have better performance in the long run and hope fully no mechanical problems, take care lataa

 

oh yea and MR Evolution....ya your ight they will burn oil like crazy if you dont break it in porperly, take it from a expert machinist, its worth doing it porperly.....enjoy the ride....lataa

 

I just got over 800 in mine, still hasn't seen the high side of 5 grand. I have a road trip this weekend, it'll be about 400 round trip, should I change my oil before or after? I ain't gonna' be beating on it, just a leisurely drive.

 

OK; thanks, all.

I have almost 500 miles on it now and I've been doing 15-25 minute city driving mostly, with some runs in the country, varying the RPMs like crazy to accomodate traffic, turns, stoplights, etc.

I have not left it at one engine speed for more than thirty seconds or so, I would wager, but I am virtually always keeping it under five grand. (I sometimes see an instant of 5,500 just as I shift, but that's rare.)

So I think it's going great. I should be through 600 miles by the end of this weekend, I bet. I will probably go with Ike's advice and wait to change the oil per the factory recommendations; most of the advice I see is that changing it at 500 or so miles is not necessary with modern engines.

 

i did a long break in also...

but my clutch still went out at 20k

 

I lost about 2/3 of a quart in the first 1400 miles. I topped it off at that point and left for Las Vegas. 650 miles later when i returned i checked my oil level again and its exactly at the full line where it was before i left. Seems all the oil loss is now gone.

 

Went to my parents house 600 miles round trip
