Why do we seem to go straight to "Nissan cheaped out" when the build and material quality of our cars is so high and doesn't indicate that mentality on the part of Nissan at all?

How would it make sense for part of the fix to be changing the oil over to Ester oil if it already came from the factory with the stuff in the engine?

Wasn't the ester oil introduced after the engine already launched? That's why it's a TSB. Unless I'm wrong on that?

I think you'll find that most on this forum consider it to be piss poor. Having said that, yes it's possible that ester isn't good for break-in. I don't know enough about conventional oils with ester additives to take a stand one way or the other though. (Here we go with a whole new can of worms! lol )

My paint looks like a gray pane of well polished glass -- no texture or color variations to be found. So yes, I believe it to be of high quality. If paint softness is what you're talking about, I have yet to find any car that effectively avoids rock chips. Every car in my past that put primarily a painted surface forward looked like it had been sandblasted after a year or so.

For the Z, I opted for a clear bra to protect my high quality paint job. It seems to be working.

Sounds reasonable, except for two things. First off, Ester oil is recommended, not required, and most corporations -- especially Nissan -- have a habit of doing what's minimally required only. Why? Because they're bean-counting tightwads (just look at how they've handled the oil-cooler issue). So I don't think we can assume that a company will fill their cars with a specific oil even if they specifically designed that oil for that car. This is especially true if said oil is more costly than the regular stuff they use. I know, that just doesn't seem right. But I've seen stranger decisions made, especially whenever there are a few bucks to be saved.

More significant, however, is the TSB for VVEL noise for the G37. The G37 has the exact same engine, so one would expect it to come with Ester oil as factory-fill as well, right? After all, Nissan designed the oil for this engine. Yet, on the Infiniti side of the house, there's a TSB for the issue of valve noise ( ITB08-028a - Noise from bank 2 VVEL actuator). Guess what the TSB says the fix is? It's a two-parter: A software update, plus changing the oil over to Ester oil! Now, let's think about this. How would it make sense for part of the fix to be changing the oil over to Ester oil if it already came from the factory with the stuff in the engine? I mean c'mon, let's use a little common-sense deduction here. In spite of designing this oil for this engine, they're filling these engines up with the cheap stuff at the factory!

I do realize that there's always a chance that they're doing something different for the 370Z vs. what they're doing for the G37. Like maybe they're using Ester oil as the factory-fill for the Z but holding out on the G for some bizarre reason. That's why I chose to characterize it as highly doubtful, vs. using the word "impossible." But I don't think it's slam-dunk obvious that they're using Ester oil for factory-fill either, as you seem to think it to be. I would be quite surprised -- pleasantly so -- if they're using the good stuff for the factory-fill.

I don't have too many chips thanks to my ClearBra, but where I do have them, every single one goes right down to bare metal. Not all cars are like that. Heck, even my 350 wasn't like that. Neither is my wife's Murano, now that I think about it.

In any case, let's not get too far off topic. All I stated was that most companies will choose the route that yields the greatest profits, and often time that means using or doing what is minimally required. That's just common business practice, especially in the current economic climate of heavy cost-cutting. Trust me, I'm a business analyst at IBM and see it every day. If we provide a customer with more than what's minimally required, we can actually get reprimanded for it because by doing so, we're failing to maximize company profits. (I hate my employer, btw.)

I suppose with that logic, you think corrosion is an asset too, right? After all, as various parts erode away, your car will weigh less. :rolleyes:
