Break-in

[harrbear]

guys, i didnt follow any break-in period, i kicked the s**** out of my mazda3 GT as soon as i took it out of the dealer with 80km on it. I hope it wont affect the mpg....can anyone help out? im at 300km now and my tank is at 25%

my gas tank is at 1/2 after 150mi.

I took it to 90 last night, didn't floor it or anything, just gradually went faster.. I must say I was impressed.. It felt so grounded, smooth and in control I didn't notice I was going that fast! I also forgot and used the cruise control for about a mile on the freeway last night too . Hope that doesn't do anything. I know you're not supposed to stay at the same speed for extended periods of time during break in.

I think i've heard that people just get really bad mileage from the first couple tanks of gas. Is this true?

re read my previous post. the engine is broke in before you get it. If you want it to last do oil changes frequently, 2500miles or less, IMO don't waste your money on synthetic, BUT that is my opinion. Rotate the tires with every oil change, if you want them to make it to 15k. the tires onthew car are great performers BUT they wear extremely FAST.

have fun and try be sure you have the updated mount so you don't be come a "true MS3 owner"

seems like my boost from 1st and 2nd is less now for some reason.. maybe i'm just not gassing it as much. dunno.. doesn't seem to turbo lag anymore.. my head doesn't go back into my headrest with authority.

shrug, might just be getting too used to the car . my previous car was a '98 vw jetta. slow slow car.

**** it.

You need to run it all the way through the RPM range multiple times. You only have one chance to seat the rings and this is it.

Yeah, I have heard this before. I tend to agree with it.

The only downside I see is:
What if there was a preexisting manufacturing defect in the engine? So you break it in hard, like this says, and then the engine blows up. When the manufacturer investigates the cause of the failure, they'll look at the ECU. Will the ECU act like a black box (on an airplane) that records all the details leading up to the failure?

I heard that Lotus did this with the Elise when it was introduced in the US. You had to go to Lotus for your initial oil change service, and they'd read your ECU and see what you were up to.

A Mazdaspeed3 is a special car, but it's not an Elise.

Does the ECU record this? Could it be used to deny a warranty claim?

I say that the engine would only fail during break in if there was a fatal defect in the engine from the factory. A weak break in may extend the life of the engine, perhaps make it last through the warranty period. Hmm.

but i dont get it, if its a manufacturer defect it should still be covered. even if the ECU copies down what happened(i believe it does, theres a thread around here dealing with ECU and some other jumble blah blah blah stuff i didnt pay attention to but it gave me a cookie either way) its a manufacturerererererer defect and should be dealt with by the manufacturer no matter what happened

I know that the E36 and E46 M3s have ECUs that log rpm data. BMW generally won't deny warranty coverage so long as the engine was not over-revved(as is caused by a "money shift" or mechanical overspeed) and/or held at the redline for extended periods. On the other hand, I know of at least one EVO owner who lost his powertrain warranty because the ECU showed that he had bounced off the rev-limiter too often...

Break her in hard! Drive it like you will always drive it. If you don't get on it ever then give the car back and let someone else. Someone else has stomped on the gas and went throught the gears before you drove it (most likely).

My test drive was with a really cool salesman and he let me tak a 10 mile road course out in the middle of nowhere. I scared the hell out of the guy but I fell in love and couldn't get the car off my mind untill I signed the papers.

Dont miss shift.... Beat it up. Has a warranty. All thought I babied mine . lol

 

[gr3y]

I'm not babying it.. i'm staying in low gears most of the time.. but i'm not beating the s*** out of it either.. i love the car way too much to do that.

here's a pic for you guys.. in case, you know, you've never seen a speed3 before.
