That makes more sense I guess we're on the same page.

 

my G has 700 miles on it...these last 500 are taking forever. I sure do miss flooring the dealers demo car.

 

+1^^

I hear that! I drove the snot out of the demo.

 

Looks like I may also have a long drive as the dealer I am most likely getting the car from is 700 miles away (on interstate ).

Any suggestions on how to do a good breakin? I am just planning on varying engine rpm and speed (between 60-80) on the way back. And waiting till 1500 miles before I increase engine speed over 4000rpm.

 

I doubt it makes any difference- the engine is built like a rock, the only thing thats going to screw it up so that youd notice is not having enough oil in it. Otherwise, the VQ likes to be driven hard, you dont need to baby it. sure, let it warm up and all, and yea I wouldn't redline it till after 500mi, but seriously no harm will be done by taking a long drive a the same speed...

 

Great advice! Just stay under 4000 rpm.

I'm sitting at 1800 km and have travelled "every" backroad I can in the last 2 weeks.

 

I'm at about 600 miles, and it's killing me. Watching the odometer tick by is like watching water boil. My car will NEVER hit 1,200 miles.

I set the 'REV' shift light to 4,000 rpms, which helps me remember to keep it under 4k. Plus, my son likes to scream 'shift!' whenever he sees it blinking, which drives my wife crazy. Bonus!

700 miles to go....sigh.

 

you know, i noticed a lot of you guys can't stand watching the odometer go up until you can really drive that thing hard..so if you want, i can take over your car until then...you know, just to make it easy on you

 

Remember.. it's not just the engine you are breaking in.
You are creating wear patterns on several components, rear-end, tranny, brakes, etc . So it's a good idea to take it easy for a few hundred miles at least.
Another aspect of break-in is for the driver. It gives you time to get used to the handling and power.
Heat cycles are very important for break-in. It's better to have more short trips than a few long ones. Vary speed on the Hwy.. drop down a gear every now and then. Don't use the cruise control.. vary your speed.
After 500 miles or so start running it up thru the rpm band. Don't do it at WOT, but bring it up a bit more every time and not under full load.
A careful break-in will help extend the life of the whole car and keep that new tight feeling.

 

Should you change your oil after the breakin (1200miles) or is it ok to wait till the 3700 mark?

 

It depends.. On some cars there is a special break-in oil used for the factory fill. Honda uses this and the oil should not be changed before 3K. Not sure about the Infinity.. but you will be fine at 3K either way.

 

Here's a link I bookmarked from another thread. I don't endorse the info on this site because I am really not very knowledgable about engine mechanics in general.

Just wanted to post it for those who may be interested.

Yet another opinion. It seems following the manufacturers advice is the way to go for proper break-in as it applies to the whole car, not just the engine

 

This is strange, my dealer said with the new engine, there is virtually no break-in period, he said drive the crap out of it but just remember to change the oil at the right times and it'll be fine. O_o
ps-i have a demo car but i bought it with 24 miles on it. I wonder who tested it before me??

 

Define you're dealer? The salesman? Yeah.. I would take his word over all others.. salespeople always know the facts and have never been known to lie.
