LS 3 break-in procedure
 
Does anyone know the correct break-in for the LS 3? I read the LS 1 and am wondering if it is the same. I 'm not referring to the break-in information in the 2SS manual that comes with the car.

Fifty different people will give fifty different answers. I don't know if there is a 'correct' one without knowing what you want from the car.

According to the manual, dont' take it over 4000 RPM's for the first 1500 miles. But Break in procedures are like a**holes...everybody's got one and they're all different!!

There are a great many posts about this

Just search "break in"

The only thing that alot of people say is to use regular oil for the break in period.Then switch to synethic oil.

the company hires engineers and pay millions of dollars to find the correct break-in procedure.

but I guess you can still not believe that the manual is right...

Um, it comes with Mobil 1 Synthetic. I'm pretty sure the engineers at Chevrolet know a little more than anybody else on these boards about their engines.

Main thing is to change oil early to rid of junk collected.Vary rpms and use quick starts and hard stops for at least 500 miles.opposite of what it was 20 yrs ago.City driving the best.You want quick revs but not too high 4000 to 4500 should be highest. Several car engineers swear by this.

kdoske 05-31-2009 08:44 PM

1500 miles is a long time to not exceed 4000rpm!!!
it will be torture!

nards444 05-31-2009 08:47 PM

theres always these billys out there that have been doing something special or different this since 1949 in their dads buick and its worked for them. Whatever, the manual was written by people who built it. what it says make sense. Its a free country so do what you want, but your also aloud to be an idiot as well. :flame:

Don't think anybody has noticed fastfred....your 67rs is sweet

fastfred67 05-31-2009 09:12 PM

Thanks. My 67 is sweet , but it has real raw hp under the hood the old fashioned way. What I read about the LS 1 is that you should us regular oil for the break-in up to 1500 miles so that every thing wears in correctly and the rings seal up tight, then go to synthetic oil. The manual says I have synthetic oil frm the factory. I' m ready to dump it now and use conventional oil to 1500. Apparently synthetic oil does not aid wear-in very well at the beginning when wear-in is most important. Make sense?

Royal Purple break in oil before the car leaves the lot with a filter magnet. Switching back to Mobil 1 after 500 miles.

and they hire lawyers to write the manuals
just sayin ?

Here is the thing. GM has a vested interest in ensuring that you break in your car in the best possible way. They have given the car a 5 yr / 100,000 mile warranty. This makes me trust that what they say has more merit than some guy with a slick nickname on a message board. As soon as someone is willing to provide a warranty for their procedure I will consider following it.

The LS3 in the Corvette comes with Mobil 1 in it from the factory. Seems like that means it is fine from day 1.

Can't go wrong by following the manual!

Phase V 06-01-2009 04:41 AM

I've heard of it but if it's better :iono:! Royal purple now.... the best!

ss1129 06-01-2009 06:52 AM

These motors have been out for years now. Search is your friend....or the car manual.

fastfred67 06-01-2009 07:24 AM

Appreciate the input on the LS 3. I bought the 2SS LS3 inferno.I want the engine to run the fastest it can and that means good wear in for sealing. I drag raced my 67 from 1967 to 75. I drove in to school and even round trips from Kansas to Tx. My best times with the BBChevy were 10.90's in the quarter and 6.90"s in the eighth. I am glad I quit racing before I cracked the weld seams on the car. It still has the original paint and original deluxe interior. It has been detuned, but I still drive with 12.5 compression, 4 speed, and street dot slicks.
