Here's a nice link, read it and stop the madness!

Stealth 316 - Engine Break-In

I just want to point out that I worked at a Toyota Manufacturing plant and as soon as the car is assembled, they do put it on a test bench and drive the car under load. They rev it up to something like 50-75% of redline a few times. And then they actually put it in reverse and rev it up under load as well. I dont know for sure but Id say probably 3500-4000, could be different depending on the car of course.

That's for sure, including This response.

Many manufacturers have a chassis dyno at the end of the assembly line where the car is run up through the gears and RPM's under load. It's part of the Quality Control procedure.
ALL Motorcycle assembly plants do for sure.

As far as a factory fill with Esther oil, no one has EVER confirmed this...Lotta gum flapping, no evidence..If you have some post it up!

LMAO. First car I owned was a 1953 Chevy that I bought in 1962. It burned/leaked oil at a prodigious rate but at 18 I didn't give a rat's *** - I had a car. It had some sort of scoop/pick-up oiling system for the babbitt bearings on the main shaft. I always knew when it needed oil because I could hear those bearings howl when I made a sharp turn (scoop wouldn't pick up enough oil when it sloshed to the side of sump in the turn). Never bothered to change the oil - just added some when the "audio" alarm sounded.

LOL...You got that right. Speaking of 12k rpm.... back in the '80s when I was running a Pro Stock motorcycle (Kawasaki), we would always break in fresh cylinders/rings with one pass on regular oil and then drain it and put in the Mobil 1. Rings wouldn't seat on the synthetic. Just wouldn't do it...period. That was when I was convinced that the synthetic stuff was the real deal. Of coarse that was a long time ago and alot has changed since then. Except Mustangs still won't turn 12,000 rpm...

So what's the final word to the first posting....is it OK or ISN'T IT OK to put synthetic in these cars......Geezzzuss - Just a simple YES or NO will do!!!!!!!

Maybe.

i switched over to royal purple 1 at approx 1500 miles. later than i normally do on the past 4 new cars ive had. this is the only one that burns oil out of all of them. as long as im not loosing performance from the burning oil, i check it often enough not to care much.

Yes.

The only cars in which synthetics are not recommended are rotary engines or some very old engines. The debate on synthetics otherwise revolves around the following:

1. When to switch and if it affects break-in. See previous posts
2. Whether or not synthetics provide much more protection than conventional and over what change interval.

So the issue is not whether it can or can't. Just if its worthwhile. ZKindaGuy, I think your service manager just didn't take the time to elaborate in his recommendation to you when he stated that the Z can't use synthetics. There is nothing in the design of the Z's engine which would preclude the use of synthetics. There are however factors which indicate it could help including:

1. Higher than average oil temps. Synthetics shear less and hold better in hot and cold.
2. High RPM engine combined with the fact that Z owners typically drive hard.
3. the VVEL system uses oil pressure. Using synthetics results in more stable viscosities and thus more consistent oil pressure as compared to conventional all else equal.

Its up to you- but again the Ester oil they recommend while not a "full synthetic" due to its conventional base oil does have more esters (an additive found in synthetics) than most synthetics on the market (except for Redline, Motul, etc.)

YES, it is O.K.--no, it's GREAT!--to use synthetic oil in our beaZts!!! End of story.

That's far different than running it up to redline, ya think? Why the reverse? Does that make a difference on the engine?

This is not about break-in.....It's about quality control. Making sure everything works before shipping

It's ester, not Esther.

Modshack, I never said they don't run the engine at the factory. I said that only Porsche runs the engine on a dyno before it is even installed in the chassis. What manufacturer would build an engine and not test it? I also said that there is no way an engine would be run up to redline.

So you are saying that Nissan recommends it's Ester Oil but does not use it? Seriously? Talk about gum-flapping! Do you know anything about the VVEL tapping issue? Nissan started using Ester oil in the VQ engine in the G37 (they also re-calibrated the ecu) because of it. The TSB is ITB08-028a. Wasn't hard to locate on the internet.

We could go on for weeks about this. The only reference to factory fill in the manual is on page 9-5 and says this..

"Your engine was filled with a high quality engine
oil when it was built."

That's not real definitive....
