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??

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.

I thought Mobil 1 isn't a full synthetic.

Roger that!

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.

hahha man that guy is full of crap.... swtich to full synthetic.... at 3000k runs smother than before.... ahhaha and no problem man if i dealer said that to me.... ill tell him straight to his face his a idiot hahaha

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 =/

Now jpit's got me wondering 'bout the cases and cases of "regular" Mobil 1 I purchased some time back! I've been using "regular" Mobil 1 since 1998 or '99, with fine results, so far...Rats! I've got something like 6 or 7 cases of 5W30 oil stored for the next round of oil changes (my 350's in January '10, and my wife's Pathfinder in February of the same year). I'm just NOT gonna worry 'bout it, 'cause I ain't gonna dump the stuff into Pep Boys' used oil drums! Only time will tell...

Listen guys they are a Nissan dealership if you have a problem with nissan's policy on the ester oil call nissan. YOu both aren't informed correctly read your owners manual and your warranty and you will find out that the current standing from nissan is that the ester oil is best for the engine (arguable personally i don't think it is and it's a scam) this is what they tell the service department to do. It is a dealer service department not regular shop so they follow the book and company policy. If you read your warranty book they will not void the warranty if you do not use ester oil just like they won't if you install a cat-back but do me a favor buy a F.I. Exhaust and try to have a nissan dealer install it and see what they say. Not that you can't do it, they just won't. Service departments that will put in an oil other than the ester oil ARE NOT FOLLOWING NISSAN RECOMMENDED SERVICE PROCEDURE good or bad it's not how NISSAN rolls.

Edit: Take your car somewhere else have them put in the oil that makes you happy and keep the receipt in with your warranty book that is all nissan requires you to do.

Where do you come up with this schitt? :icon14:
