I would e-mail the NNA rep back and tell them their are 2 maintenance schedules for the Z, just like other Nissan vehicles:

Schedule 1 is 3750 oil change intervals(just oil, not filter)for hard usage reasons and there is a long list of them in the customer's manual;

Schedule 2 is 7500 mile oil and filter change intervals for regular usage. Tell them you want a technical representative that is aware of what the manual contains, not some Public Relations person who obviously doesn't know much about their own product. I would like to hear this sweeping statement from such a knowledgeable employee of NNA.

Have you read your owner's manual? Every owner should read the manual cover to cover, so you can refute idiots who are reps of large corporations, who only know what they read and, in this case, they should have read a page or two further and they would know about schedule #2. How many years has it been, guys and gals, that owners' manuals have used the 2 schedules? 20 yrs? 25? 30? I can't even remember when I bought a new car without them.

Boomer--please send the moderators a copy of your 1st e-mail and your 2nd, if you choose to send it. This crap needs to be stopped now. Next time, when anyone e-mails NNA, be specific about what needs to be addressed and ask for an expert, not a PR rep.

 

Why did they use 10W-30? Nissan's owner's manual says 5W-30. It won't hurt anything, but 5W-30, mineral or syn, the car companies have chosen to rec'd it in the cases I've seen. And, yeah, there are a lot of people who don't use syn while the car is breaking in(a non-issue w/1200 miles) because the valves don't seat properly with syn, so don't use it from the factory. What about Corvette and BMW? BMW's equivalent oil, if you can't get theirs is Mobile 1.

Boomer--curious. I do know the motorcycle fans are adamant about breakin, no syn until the engine is fully broken in.

 

Ditto. Cold starts are easier, less wear on engine parts, more heat resistent, etc. The extra protection is worth the extra money to me. If I changed my own oil, I might have a different attitude. My aptitude is not wrenching, I did it for years and always seemed to do something that hurt me, not the car so I stopped.

is there any advantage to not changing to mobil one (or other syn) at 3000 miles? how about one of these partial synthetic products?

 

Yes, there is an advantage, your oil will cost less than Mobile 1 or Castrol Syntec, or other syn oils or blends. If you change your oil every 3000 miles all the time, you are in good shape, oil-wise. As one of our astute members on this thread pointed out, regular maintenance is key to maintain your Z's health, mineral or syn, or other oil changed regularly will ensure it. Being more fanactical, I would change the filter too. You don't have to, but I hate leaving dirty oil in my engine, so a new filter takes care of that.

[B]I got the email response from NNA. They said that synth would not void the warranty as long as you have documentation of changing the oil every 3750 miles.

That is such BS from Nissan. Their own owners manual states that if you want to use their "Premium Maintenance" then the 3750 mi. rule applies.

Their "Schedule 2" maintenance requires 7500 mi. intervals. This is the MINIMUM requirements required to maintain warranty. That being said, we may "Choose" to change more frequently than 7500 mi. but to require 3750 mi. intervals is BS. Page 13 of our Service & Maintenance Guide. If using full synthetic oil, MY opinion is that 5000 mi. intervals are sufficient. JUSY MY OPINION.

Its OK, JDC. It does serve a useful purpose, you don't want to ignore your maintenance schedule and be looking at a multi-$1000s repair bill because you weren't paying attention.

Boomer--NOW let's kill him! Just kidding!
