No Full Synthetic Oil in the Z?
 

So, I went to get an oil change at the dealership where I bought my 370Z. I asked the service advisor about using full synthetic oil instead of the regular oil they use. He informed me that the 370z cannot use full synthetic oil. I asked why. He then said that Nissan engineered that engine that way. Anybody else know about this? It doesn't make sense to me. I've used full synthetic oil in all my cars and motorcycle.

dudes full of shyt, been running full synth since my first change at 1500 miles.

It's recommended, at the very least, to use Nissan's Ester Oil for the first oil change, especially if you're doing it during the break-in period for the car. Nissan Ester Oil is recommended, but not necessary.

Many members have switched to full synthetics such as Redline, Royal Purple, or Mobil 1 at the 3k, 5k, and 10k marks, none of those with any issues.

What is the logic behind that statement? How could one build an engine to only work with a blend?

He's an idiot.......:shakes head:

I hit "submit" a little too soon. So anyway, engine parts are still engine parts, it produces the same heat, so if it's all the same, I don't see how this statement holds water.

Just another example of people making things up and overstepping their knowledge base.

I know ALL engines in the WORLD can use 100% synthetic oil EXcept the Mazda RX-8 Rotory engine..

Don't try to find logic in stealerships' requirements, dude. Their only "logic" is $$$---as much as they can get from you! Synth' oil is THE best choice for any engine (see previous post for the exception). Period. Some cars even leave the assembly line with it (i.e. by the manufacturer). So, ignore that nitwit's comment and go synthetic!

I'm not planning on going back to that dealership. I found the DIY oil change sticky and it doesn't look that bad. I'm going to see if I can get my money back for that stupid Maintenance Plus that I bought.

I have a '99 Mercedes-Benz...MB advised me not to use synthetic oil until at least 5000 miles on the odo. I have no idea why. But I followed the rec and now have 138000 trouble-free miles on that engine. I have only used Mobil 1 for the life of this vehicle.

Changing the oil on the 370Z is VERY easy and it is worth the effort knowing that it was done right. I ran the initial oil up to 3500 miles then went to Mobil 1 full synthetic and the car runs fine. :tup:

Never rely on a service adviser. Next time talk to the service MANAGER or at least a mechanic. Service advisers are customer service reps, nothing more, and most are clueless about mechanical issues beyond the minimal items they were taught in a customer service training class.

I've used Mobil 1 on my '01 Montero Sport since the first oil change and I've never had any issues, it now has 202K miles on it. This is the reason why I asked about it with my 370z.

If that was the answer I had gotten from the 'service advisor' when I took mine in for it's first oil change, I would have gone directly to both the sales and service heads and told them that I will not do business with a dealer that has so little respect for their customers that they will just fat out lie to them like that.
That would have landed that service jerk on the hotseat and started a whole lot of a$$ kiss'n to make me happy.
What happened in my case was I was told that "while the ester oil was recommended, using regular oil would not void the warranty so the choice would be up to me". I already knew that so that was the right answewr. Then he added.... if I wanted to go to synthetic they would simply charge me for the difference in cost of the oil and if I want to save some money, he recommended I buy the synthetic by the case at some place like Walmart and they would put it in for me at no charge.
Obviously.... some dealers are better than others.
