How long to break in engine?

slrvstang2007 · October 7th, 2007, 10:41 PM

everyone tells me to go easy on the car at first, so i been driving it like a granny shifting at 3000 RPM never letting it get over 4000RPMS, when you guys think its ok to really get on the gas, i got 400 miles on it now.

give it another 100... change the oil.

than another 200 or so.

I went till 500 miles shifting @ 3 grand or less, after that, I've been driving it like I stole it

I beat the shit out of mine from day 1. lol

slrvstang2007 · October 7th, 2007, 10:45 PM

change the oil at 500 miles? why?

HMUSN · October 7th, 2007, 10:46 PM

in brand new engines (like 0 miles) your oil will break down very quickly because it's the first oil the engine has seen and it engine absorbs most of it.

Because that's when the engine is really breaking in, setting the rings, the cams, etc.

Some guys don't believe this, but although I beat the hell out of mine from day 1, I changed my oil over to synthetic and did that at 500 miles.

slrvstang2007 · October 7th, 2007, 10:47 PM

ah got it, what kind of oil do you use?

TheUNZippee! · October 7th, 2007, 10:48 PM

I use Mobil 1 synthetic.

HMUSN · October 7th, 2007, 10:50 PM

that's what I used.

06GTMustang89 · October 7th, 2007, 10:51 PM

and synthetic as dynoed out to give 8+ hp over conventional on the 4.6L so you really can't beat it change it at 500 and drive it like you stole it brother!! haha

slrvstang2007 · October 7th, 2007, 10:51 PM

hahahahahha

I would actually wait til 1500 miles before running the hell out of it/modding it.
a tuner here in my town thats been doing mustangs for 30 years said its a good idea to wait til that long, hell, my friend with the new gt500 took it there, and he said he wouldnt touch it til 1500 miles.

psycho bob · October 7th, 2007, 11:17 PM

when i got mine i decided to just read the manual. it says nothing about driving it hard from day one. it does however say to not drive it at constant speeds for the first 500 miles i think. that just means no long drives immediately.

Grabber523 · October 7th, 2007, 11:21 PM

Yup, be nice to it as long as you want, drive it as hard as you want, just make sure you change that oil at 500...get all the shrapnel outta your engine...then again at 1500, then again at 3000...then mod the f*ck out of it!!!
