Engine Break In

Ok, so I will FINALLY be getting my car back this weekend, new engine and all. I am going to break it in with conventional oil, but my question is easy break in, or should I goose it a good bit from the get go? I've heard positive and negative issues for both....

 

Drive it like you normally would Change your oil after 100 miles.

 

100 miles? Everyone I've talked to has said 1000.

 

i think the unanimous opinion on this board is as Eddie said. drive as you normally would use cheap conventional oil, change oil after 100 miles, then again at 500, then start your regular intervals after 1000 with the good stuff. or something close to that

 

Then that I shall do. I'm sure I'll be doing my first oil change on the first night. Plan on driving the hell out of it.

 

Do NOT put ANY synthetic oil in until after 1000-1500 miles.

 

Also search on here....I've covered the break in procedure in the past. It'll be under the CoolRex name.

 

change the oil after you get all the air out of the cooling system, usually takes about 30 to 45 minutes. this way it has gotten up to operating temp, and you can flush all the crap out of the motor. Do it while hot that way all the trash is still suspended in the oil and not layered on the bottom of the pan.

this...

also, on break-in. Vary the throttle as vacuum helps the break in process to seat new rings. Regular Dino oil till at least about 1500 mi. Then change to Syn.

 

Oh trust me, I wouldn't run synthetic yet. I'm running Valvoline 5w30 until break in is complete. Although, sometimes I wonder about that because you see so may new cars, like corvettes and such, coming straight from the factory with full syn.

 

They are already broken in.

 

I know all of the newer Audi's come with Synthetic from the factory and I am pretty sure those motors are not broken in at the factory. My A4 had problems seating the rings when I first purchased it so I changed the oil and put regular dino oil for 3500 miles and that solved the problem. Engine ran fine after that.

 

If they are already broken in, then essentially, wouldn't they already have about 1,000 miles on them?

 

I thought most engines are at least engine dyno broken in to make sure everything is good? Maybe not broken in but at least ran.

 

You do know the odometer on your means mileage the chassis has traveled don't ya? You can crank up a car and let it idle for years only turning it off to refuel/change oil yet the car will read no more miles than you started.

 

How can you properly break it in though, without physically moving the wheels. Whether its on a dyno or not, a thousand miles is a thousand miles. My question is, are they doing this before or after the cluster can read it? If I paid damn good money for a high performance car like that, I'd be pissed if it already had 1,000 miles on it. Now maybe, just maybe, the parts are broken in by machine before installed? I don't know.

 

Ever heard of an engine dyno?

 

This was worthy of reposting

 

spun on a "test" fixture not a dyno
