Engine Break In

hey guys, i was reading a bunch of articles about breaking in the engine of a new car... from web sites to manuals... and i ended up being confused about it... there's a lot of opposing facts... some say "take it easy" and some say "bring it on" another said "harder, harder"... sounds like that... but, anyway, i had a lot of questions already answered by "good guys" here in this site... and i appreciate it very much... and if you don't mind here's another one...

this is my first brand new car... it had only 1 mile when i took it off the dealership... now it has 240+ already... and between that i just drove it "normally" i guess as how would i've driven a stick before... not going over 2k too much on the rpm (to also save gas)... and shifting a little earlier than what is recommended in the manual (15-25-40-45)... it had some pinging or knocking sound when i accelerate but i guess that's normal when you upshift too soon... i don't know... i don't even know if i'm talking right...

so, what do you think... have i done something wrong?.. should i be punished?.. i've read somewhere that "the first 20 km or mile" is the most critical during break in since it's when the the piston rings seal perfectly around for good combustion pressure... BUT... since i'm already past that... does it mean im stuck... that there's no way that i could make a "mean" machine out of my new car? (aside from installing new one's and doing it all over again)...

so please help... what is really the best way to break in our new tc's and do i still have a second chance since i've driven mine everywhere already? thanks guys!

bro, dont sweat the break-in stuff....... Strict break-in processes were developed back in the day before clay-molded engine blocks etc. The tolerances and cleanliness of a new Toyota engine just requires you to drive normally and save the lead-foot for after 500+ miles then gradually get on it more and more..............and thats it. Change your oil at 2000 miles and youll be all set, trust me. - T
so i guess i'm on the right track then... wow man... you seem to have a lot of answers... you'be been a big help... thanks...

no problem , everyone has their "thing" that they know a lot about.......and mine is cars (and marketing but this is not a marketing message board haha). Hopefully I can continue to help people out and continue to be helped out by other people on here! - T
Yep, I'm so glad we have awesome people on this board....can't say that enough!!!!

Check your owners manual. it will have a section (look in the index) called 'break in period'... usually it is the first 1000 miles. it will tell you all the do's and dont's.

just drive at different speeds and after about 1,200 miles you can go crazy
I saw this somewhere else (can't remember where). I'm still confused on what the right answer is...

JackerCrack, I'm no expert, but I think shifting before 2k rpm is bad. You're putting a lot of stress on the engine by not letting it get the car moving effortlessly. This isn't a V8......

yep im not doing it anymore bro... im going by the book now, 15-25-40-45 shifting patterns... not completely exact but with a little more or less adjustment... i'm setting up my mind whenever i start driving that the car is attached to my body and i should notice and know when it's starting to hurt or not doing enough effort. i guess that's the way i should put it. not an expert too you know. but thanks for the info though.
