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.

I've used full synthetic oil in all my cars and motorcycle.

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.

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.

There are two types of stealerships: The bad and the worse. No two ways about it!

The dude is full of crap. I had to top off my oil, and the local Nissan dealership told me that all they used was Moble1 synthetic.... How can a car not be designed to run on synthetic?? Did you mention to him that factory oil is part synthetic??

j.arnaldo · 11-07-2009, 12:36 PM

No use arguing with 'em; they look down on their "valued customer$"!

I've changed my oil at 1400miles to Redline synthetic and have had 0 issues and the drive is smoother.

jpit · 11-07-2009, 08:06 PM

At one time Mobil 1 was fully synthetic but they lost a lawsuit to Castrol who advertised their oil as fully synthetic but was using an organic base. Mobil then changed their formula and started using an organic base which is cheaper to produce. A few years ago Mobil came out with their extended performance synthetic oil which is fully synthetic.

Using Mobil 1 full synthetic, which was recommended by my dealer. No issues.

simota1 · 11-08-2009, 02:27 AM

Something like 90% of break-in occurs when the engine is first fired up, and most japanese manufacturers strap it to a dyno and run it all the way up to redline under load to prove it's a good engine.

So, taking that into consideration, there isn't really any "break in" that needs to be done with conventional oil. Plus, with our cam system, we need all the lubrication we can get. If you feel the need to break in your engine, and you put in synthetic oil, figure you just need to hammer the throttle a bit harder than the guy driving like a 90yr old grandma with a reaction time measured in minutes, to make up for the lubrication property differences...

The dealership where I bought my motorcycle tried to tell me the same thing - I spent 2 minutes arguing with them on why that recommendation is BS, and they finally said something to the effect of "it's your bike, we're just saying..." and I finished their sentence with "a load of ********", and I walked out...

All I was ther for was for a couple crush washers =/

Sorry, I assumed it was a standard industry-wide practice, but I guess I was referring to motorcycle engines as the basis of the second half of my comment.

The first half is just plain common-sense. Maybe the percentage is off...but whatever.
