i think his car will be ok

 

I just don't understand why anyone would refute the owner's manual that was created by the manufacturer of the car based on recommendations from the engineers who have designed and tested the vehicle over and over to gover 9 generations strong. Do you think they are keeping a huge secret from us and in reality we are supposed to rag on our cars fresh out of the box to make them bullet proof?

 

Here's an interesting link on engine break-in

so... mobil 1 synthetic 10w30???

 

It is so funny how people can read something on the internet or a message board and take it as gospel truth. The bottom line is Mitsu made the car they have tested the car and they have the most gain from giving the correct info on how to use and take care of the car. I would be willing to bet the section on how to use the radio in my owners manual has more thought and time put into it then most of what you will read here on else where or the internet.
I did the manual breakin and changed the oil at 1k and will change it at 3k intervals w/ mobile 1

 

you done ****ed up

 

I did my first oil change at 1,000 miles.

 

The main reason for using synthetic oil in your Evo is to help prevent plugging the turbo oil feed line with coked oil. This can happen if the engine is shut down with the turbo very hot. If the turbo oil line becomes plugged you then lose the turbo. Synthetic oil is less susceptible to oxidation at high temperatures.

I'm from the DSM crowd and most turbo 4G63 DSM's were driven with conventional oil in the crankcase with only the occasional problem. I personally drove my DSM over 100,000 miles using mostly conventional oil. Some winters I switched to synthetic oil to help with starting problems. The starters on DSM's were kind of feeble.

So, while this is enough of a reason for the maker to recommend the use of synthetic oil, it doesn't mean you will automatically ruin your engine with a fill of conventional oil.

 

i feel sorry for your EVO!!!! You should have took really care in Breaking that thing in. Think about it, it's like baking a cake. You dont wanna put any load on that Brand new motor and keep from Cooking the "Brand new gaskets and Seals. " Breaking in your motor correctly will Definitely increase the life of it in the long run. I can see, you running in to probs when before your first Timming belt change....

 

only 03s experienced oil related probs from hard brake in

ur cars fine dude.. but definately use synthetic unless u plan to leave it stock and not drive it hard which doesnt look to be the case

 

This has been endlessly debated and people's opinion differ. First, you should probably always listen to the mfgrs recommendations- that makes sense. Saying that, do you really think that when you buy a car with even 5 miles on it that it hasn't seen over 5000 RPM? What do you think they do at the factory when they test run the engine and car? They dog it, and they should to see if there are any problems.

In addition, here's a datapoint (real info, not "you just ruined your engine" coming from a 23 yr old psychic internet mechanic that's never even rebuilt a lawnmower engine). I bought a new AWD DSM in 11/91, drove it hard right off the lot, regularly to 7000 RPM with no easy "break-in" changed the oil every 3500-4000 miles with at best 50/50 synthetic/conventional. The engine has 267,000 miles on it, never been rebuilt, and uses a qt of oil every 1000 miles. So, I'd say you didn't ruin your seals, gaskets, rings, etc and will be fine.

Also, why do people religiously say "listen to the engineers" with reference to break in (I can't argue with that) but then change their oil at 1000 miles- which is not listening? Save your money and go at least 3000 miles between changes unless you're truly road racing the car- on a track, not a few seconds of WOT here and there in daily driving.

 

As several individuals have pointed out, people have different opinions about break in. I put weeks of research into this topic and ended up deciding to use MotoMan's method. http://www.mototuneusa.com/break_in_secrets.htm
I did my first oil change at 26 miles. This was after trailering the car (new with 4 miles on the odo) to my local Mustang Dyno to break in the engine. Engine oil was changed to regular petroleum for the first 200 miles as Synthetic limits proper break in (works too well). The oil change at 26 miles revealed oil that was absolutely full of tiny metal shavings (just as MotoMan said). Since using this method, my Evo has been perfect. I use essentially no oil between changes. The rings have have sealed perfectly. Compared to other “stock” Evo’s, my vehicle seems to have a decided advantage at the racetrack in the power department. MotoMan’s advice comes highly recommended.

 

kinda funny, when you assume that. You read the manual or whatever and forgot to find out "what if i drive it hard?"...oh well, i did my first oil change...2,500.

 

Just thought I would contribute my personal experience with the '03 i bought brand new.
I followed the normal break in.. didnt get on it for the first.. 1200 or 1500 miles ( i forget)
and I didnt change my oil until 5,000.

It went through this weird phase where it burned oil alot- (about 1 qt every 2000 miles).. from about maybe 10,000 -15,000 ( if i remember correctly).

then after that the car was fine. never burned much oil in between changes after that.

So far im waiting for 5000 to change the oil in my 9 ( got 3200) but I really havent gotten on the car too hard. ok.. maybe a few times...
