oil change price... it's like, WOW!

I do want to spend more. I never use cruise control in my car until few miles WAY WAY down the road, like 5,000 or 8,000 miles, Yes i go to that lenghts so i dont mess with the engine.

In my 350z i used Royal Purple Religiously, now with the ester crap i planned on using it until i was sure i wanted to continue to use Royal Purple.

No where in my plans did formula shell come in. See what i mean? That was never part of my plan. Im the type of guy that i want it the way i WANT IT, and dont mess with that. Obviously i dont want the moon to fit in the palm of my hand but i keep my wants realistic.

Adding this, guess what i only use chevron also, Costs more. The cheap crap gas is allways right near a chevron too, but i dont faulter.

Thats too bad man... I would stay the fvck away from chevron if i were you... I get chevron once in a couple months and thats it. The techron they add to their gas mix can be harmful to your engine life if constantly used... There might be no real evidence of it but why take a chance? It does have extra stuff that engines were not supposed to burn lol... same w/ shell... stick w/ 76

What says that Nissan Esther is better than another leading oil. It'll only take a few months before someone sends their oils out for analysis and I'm going on record now saying that those will conclusively prove there's no need to spend $12 / quart for this pixie-dust Nissan oil.

The Chevron/crap gas station comparison is not a valuable contribution to this thread. I've seen no one on this thread mention using some crappy no-name oil like Kendall or GreatWestern or whatever. People are talking about Royal Purple, Mobil-1, Motul, etc. These have been proven time-after-time in VQ engines (although Mobil-1 isn't that great actually). To me, this recommendation is not too different than if Nissan "recommended" Chevron Premium and someone decided to put Shell in it instead (both top-tiers gas). Again we're not comparing this Nissan magic-juice to crap oils.

Even Castrol GTX performs really well in just about every VQ engine to date. I'd be using Amsoil if I got a 370z and I'd have no hesitations about it.

To the guy who said the dealer can deny warranty because you didn't use the recommended oil. That's complete BS and would be illegal. There are laws specifically written to prevent that sort of issue. If it was a "Requirement" it's one thing, if it's a "Recommendation" it basically doesn't hold any weight.

I generally tell people the best thing they can do is use a quality DINO and change it every 3k miles. My favorite mainstream DINO is Castrol GTX. I use it in my Infiniti because A) it's a lease and I have no intention of keeping it. B) I change every 3k miles regardless C) In oil analysis GTX outperforms Mobil-1 (on 350z/G35).

However, since the 370z is likely to be driven more aggressively by most drivers, and some of the overheating issues documented, I'd be inclined to run a top synthetic: Amsoil or Castrol Euro Formula would top my list.

I dont want to find out that you NEED it after i have not been using it. remember a test can go both ways.

If you NEED it, it'd be a requirement. This engine isn't brand new, it's been in use in the G37 for a good year now. Usually within a year there's the signs of whether something is going to be wrong.

Regardless, if it turns out there's ANY problem and that the car must have this special oil, Nissan will be responsible for any damage caused by not running it since it's a recommendation and not a requirement. It's not unheard of for entire engines to be recalled (see e46 M3 for example). My point being, read things literally: REQUIRED = NEED TO DO. RECOMMENDED = Optional.

The fact that it's optional means using any other high-quality, proven synthetic is still ok and still exceeds the requirement. If it gives you peace of mind, I say go for it. A regular synthetic oil change will cost you $60+ and it seems others have been able to get Ester changes for $80 so it's not such a big difference. However, at $120 it's bit more of a contemplation.

The valvetrain info is interesting.
