One of my best friend's is an an engine assembler at the plant in St-Catherines where they build LS3's (not sure if they build L99s)...
They are loading your new car with 5W-30 Mobil-1(other oils can be used as others pass the GM standard for lubrication such as Castrol Professional) at the factory. Sorry to burst your bubble but no such thing as break in oil....even the dealer was trying to tell me not to change the oild early cause of the "break in oil".....funny....

 

Is it a bad idea to change the oil early on a fresh new engine? I wouldn't think so but what do I know...

 

Regardless of the age of the engine, the only thing that gets hurt when you change your oil sooner than necessary is your wallet.

It can be worthwhile, though... an oil change is far less expensive an an engine rebuild.

 

I think its a good idea. Who knows what little bits and pieces might be in there from production and assembly.

 

I just had my oil changed yesterday in my 2010 Camaro SS. I reached 725 miles.

 

It's always a good idea to change the oil early in a new motor. Any small burrs on the moving parts get worked off. It sure won't hurt to get that stuff out of your engine. I always change mine at about 500 miles and put in fresh Amsoil.

 

Here is a fact that all of these guys are missing. GM has given the powertrain of these cars a 5yr 100,000 mile warranty. Based on the fact that they have all of the risk and the designed the engine why not just follow their instructions and be done with it? The old 3,000 mile oil change blah blah blah was created by the companies the own express oil change stores.

I do tend to agree that it makes sense to change the oil early for the first oil change but even then 700, 1000, 1500 miles or whatever is arbitrary. If it was needed GM would require it because they have the liability if they are wrong.

 

No there's no such thing as break in oil (for the LS motors anyhow).

I'm of the belief that a pre-scheduled oil change is good security. I know the oil gets filtered but there's still some metal fragments that circulate throughout the engine. The cleaner the oil the better for your engine, IMO.

I've been told not to baby the engine either from early on as the rings can take the punishment... just to break her in properly!

 

So glad this was brought up...I am at the 500+ mark and want to know what the experts think.

 

Changed mine at 60(100kms) miles and again at 1000(1500kms) miles(today). Running Mobil 5W30 as factory expects. Will reset oil life monitor with instructions in manual tomorrow as I did not want the techs at the dealership to drive car or play with it (mob scene there as I did it at a Pontiac store and none of them had seen one up close). I drove it in onto a drive on hoist (dont let them use those hoists with the arms if you can avoid) and I drove it off myself. Nobody touched her except for oil change. I go to pay (brought my own oil and PF48 filter) and they said "NO CHARGE"...we just loved having that beautifull Black SS in our shop....Amazing...Never have gotten a freebie at a GM store.
My friend at the engine plant says that there are potential contaminants in engine when built dust, gasket remnants, microscopic shavings off newly manufactured engine parts and its a good idea to dump early and to get a new oil filter in her as some of that stuff is filtered in there.
Now I will run the oil until oil life monitor says 50%. Then she gets chaged again.

 

I cut open the filter on my 2002 Firehawk after 500 miles and it had a lot more grey goo in it than I expected. Since then I have always given my cars a quick first change.

Let me give you my expert opinion.....

Like someone else stated any particles from the machinig will be flushed throughout with hot oil at operating temp. (as small as they may be) I sure would change mine in a new engine..... I would also use a non synthetic. There are so many reasons why. Your main thing with break-in now days that differ from 30 years ago is #1 the camshafts.... we are using rollers now so there is no break-in for them like long ago. Also honing process are different now and clearances/materials etc have all advanced in technology. Even though we have far better products today I would still not chance it.....

I have worked for 2 dealers and seen all kinds of stuff a simple oil change could have prevented in brand new vehicles.

I am not a fan of synthetic oils at all and My opinion is they are worthless.

If you have a brand new 40k car your really willing to chinch on oil changes? Your a bunch of cheap bastards

 

I think I would change the oil in my new car earlier than usual. I have more interest in keeping an eye on the oil level, making sure the level is where it needs to be. If it was eating it, I would obviously need to get that checked out.

 

I didn't change the oil in my trailblazer SS until I hit the 3000 mile mark. It's just fine. Purrrrrrs like a kitten.

 

"I am not a fan of synthetic oils at all and My opinion is they are worthless".....Oh boy....get your flame suits on boys.... How about...Longer change intervals, in general better Used oil analyses according to many lubrication websites, (bobistheoilguy.com), better additive packages, more stickiness to cams and above (head etc..) when cold....faster oil pressure pick up and better flow at cold temps....I dunno...maybe it's the marketing and profits that the oil guys derive from synthetics but I ran a 92 toyota Camry for 627,000kms on Mobil 1 5W30 from new with a 2.2liter engine (4cyl)...(wife commuter) till it was demolished by an idiot....that day..the car was running perfect and burning 1 liter per 8000kms....
Valve cover was pulled at 500,000kms and the lobes and cams were absolutely flawless...Now...who knows ...maybe basic GTX would have done the same....
I get the feeling that the guys at GM engineering know a thing or 2 about oil and their motors and I dont think they would have a synthetic mandated standard plastered on the oil cap, in the owners manual etc....just to have one. Ran my LT1 in my 94 Z 28 on Mobil one for 12 yrs....beautiful cold starts after a winter hibernation....no oil consumption and once a yr changes....My opinion is that I go by what the General says and just try to improve on the early changes.....Once a yr cost about 75 dollars per yr. Worth it.
