Thanks. Technology changes I know.
 
As for break-in oil. The dealer dropped my oil at 1000 miles. They did not offer any comment regarding break-in and keeping the original oil in the car longer. Of course, that's not to say they would were it true of the Infiniti, but one can hope.
 
Noted regarding send a sample out. Good idea.

I personally have used synthetic in my 01' TL for the last 4 years. The engine runs much smoother and the mileage is better by about 1 mpg. Recently on a 1600 mile highway trip I got 33-34 mpg at 75-80 mph. Since I live in Florida and synthetic does not break down in the heat it is a big help. I change it once a year, about 8-9 thousand miles. You can feel the difference in the performance. I can only imagine that in the colder weather it will perform even better. It doesn't get thick in colder weather and holds it's viscosity much longer. You have to believe that if some premium auto makers are using it expensive brands that it does have it's advantages. They would not risk engine failures due to oil. I think overall the advantages are great, dealers do not want to do it because of the cost.

Not sure if this helps . . or if its even rational, but a buddy of mine is a Lexus Tech out east. He told me one day, well before I bought my g35x, "Dude, would you buy a chainsaw and cut twigs with it for 2 weeks before you finally cut down the tree? Drive what you buy like you're going to drive it from now on." It may not be good advice, but I like the simplicity .

Very true.
I had a friend who had his Dodge Challenger engine rebuilt by a very reputable local company.
He asked about engine break-in and they said to just drive it, no worries.
 
I still break my new cars in in the recommended way.
No hard braking or acceleration, vary speed and rpm, that sort of stuff...
 
But look at Ferrari.
They hand build their engines, even forging their own blocks.
They don't break the engines in.
As soon as a car leaves the assembly area, it goes right to the race track in the back yard, where every model is driven right to it's limits and tested before it ever leaves the factory.
 
So, I'll continue to break my cars in, but who knows what it's actually getting me.
The investment makes it worth the effort and hopefully, it adds to the longevity.

During the first 12K Follow these recs to obtain max engine performance and ensure the future reliability and economy of your new vehicle.
 
Avoid driving for long periods of time at constant speed, either fast or slow. Do not run engine over 4k RPM.
 
Do not accelerate at full throttle in any gear
 
Avoid quick starts
 
Avoid hard braking as much as possible

It's actually only for the first 1200mi not 12,000

Yup... those are typical break-in rules.

I worked for Infiniti and know first-hand:
 
DO NOT USE SYNTHETIC OIL UNTIL AT LEAST 12,000 miles are on your odometer!!
 
Synthetic oil is great, but for the VQ (as well as other engines), it's best to put some miles on it before converting to synthetics. This is to allow the valves to seat properly as well as other mechanical reasons. I would actually wait about 15,000 miles myself.
 
You're better off changing the tranny oil to a higher quality oil....especially knowing how hard some G drivers are on their rides!
 
Good luck!

I picked up my 2007 G35X about 12 days ago. In order to get black on black with all the toys I took a car driven on test drives which had about 600 miles on it.
 
I was concerned about how the first 600 were layed on the engine, but not concerned enough to wait for another Black on Black to arrive.
 
Here's hoping "being gentile" for the first 500 or so isn't too big a deal as I have no idea how the first 600 went on. Though observing the folks test driving lead me to believe they weren't "going for the gusto" with the salesman in the car.
 
My test rider was a 2007 Sport, I didn't get on it until we were on route 95, and even then it seems that 3800 RPM takes you to about 80 MPH, fast enough for a test ride.
