Also, I wasn't aware of this before I bought a Juke but the AWD versions have the option of going FWD, AWD or Full-time AWD (like 4x4).

The Juke has a cool new AWD system called Vectoring. Here's the video link that explains it:

Nice on the turbo then! Are you going to use a synthetic?

The video is quite impressive, I do not think I have seen any other AWD using similar technology or perhaps I have not paid attention.

After reading bitog for the last couple years, I think once my warranty is done than I will. My Nissan dealership gives a great deal on oil changes so I just pay for them until the warranty is up for now. I'm pretty sure the dealership is using Kendall Dino oil, I should call and check for curiosity lol

My only concern would be the turbo and conventional oil. Turbos can get really hot and (unless Nissan did some serious engineering) I would be worried about the conventional oil coking in the bearings of the turbo. Turbos and engines that have varnishing/sludging issues would be the only ones where I would use the phrase "using a synthetic is cheap insurance" (if you know what I mean)

I've read bout this too... I'll ask the Nissan techs tomorrow and see what they say.

edit: I do want to add that 'nowhere' in the Nissan Juke manual does it say the requirement for engine oil is synthetic. It just lists 5w-30. Premium Gasoline is recommended for maximum performance however.

No worries; it may be perfectly fine to use a conventional oil in it--Nissan may have planned for this in the design. I just wanted to point it out.

For what it's worth, Nissan tends to have rather short severe service OCIs of 3750 miles.

Would still use a synthetic to protect the turbo in this application.

OK 2010_FX4, just got off the phone with a Nissan Tech servicing my area in Western Wisconsin.

Question 1 - What brand of motor oil do you guys use for the oil changes?

Answer - Mobil.

Question 2 - Why doesn't Nissan recommend using synthetic oil in Turbo charged cars like my Juke? I don't see it anywhere in my owner's manual.

Answer - Synthetic doesn't break down as much but there's a pro and con for using it.

Synthetics trap in more dirt than dino oil and that oil is going through your turbo also. Synthetics have a higher burn tolerance but the oil change price will be almost double.

Question 3 - Do I need to allow the car to cool down (idling 2-3 minutes before shutting off) to prevent oil buildup in the turbo after driving around? I heard that oil can get caught in the turbos and will get coked up inside of them.

I have never heard of such a thing but if that were the case I would think idling may be worse as it isn't getting any air to cool the turbo. Turbo's are designed to already push air and oil through it to help cool down and maintain itself.

Wow, we don't really get these types of questions. We really hadn't had the Jukes around for that long, so I really can't tell you if the turbo's in them are really good or really bad. Maybe when we get one with 100k miles on it and we tear it up we'll know but so far no one's had issues with them or the engines.

Question 4 - I guess I understand the Juke's haven't been around that long but Nissan's had turbo's before in their 350/370Z's.... They still haven't recommended synthetic oil yet?

Answer - It really does depend on the application for what you are doing with the car. But conventional oil is fine.

Well, that is my conversation I had with the man and he was nice. Not saying what he says is 'be all end all' but it is what it is.

Answer - Mobil. [Which Mobil would be nice to know; i.e. Mobil Super 5000, Mobil 1, Mobil 1 ESP]

Question 2 - Why doesn't Nissan recommend using synthetic oil in Turbo charged cars like my Juke? I don't see it anywhere in my owner's manual.

Synthetics trap in more dirt than dino oil and that oil is going through your turbo also. Synthetics have a higher burn tolerance but the oil change price will be almost double. [Oil filters trap dirt, not the oil. I do not agree with that one. The price is about double for synthetics, but you can find "specials" that will reduce that significantly.]

Question 3 - Do I need to allow the car to cool down (idling 2-3 minutes before shutting off) to prevent oil buildup in the turbo after driving around? I heard that oil can get caught in the turbos and will get coked up inside of them.

I have never heard of such a thing but if that were the case I would think idling may be worse as it isn't getting any air to cool the turbo. Turbo's are designed to already push air and oil through it to help cool down and maintain itself. [I am not sure what type of turbo design is there, but some turbos have cooling lines attached that help cool them. I have never heard that allowing a turbo to idle causes problems, but I have heard that shutting them down without idling may cause issues due to zero oil flow with the turbo still winding down. This may not be the case with modern turbos, I am sure some of the turbo guys here on the forum will add some thoughts here.]

Answer - It really does depend on the application for what you are doing with the car. But conventional oil is fine. [Nissan may have designed it so that conventional is fine, but with the heat loads and demands of a turbo, if I were mine I would use a synthetic oil with a good filter, like Mobil, Bosch D+, Purolator P1, or Nissan if it is a good one.]

Well, that is my conversation I had with the man and he was nice. Not saying what he says is 'be all end all' but it is what it is. [He sounds like a nice guy, but I am not certain that he is fully knowledgeable about turbo-charged engines (not that I am, but I have some knowledge).]

 

[Garak]

At least up here, they use whichever Mobil product you want (or are willing to pay for), with Mobil Super conventional being the default choice. I'm not willing to pay them to do my oil changes, so the point is moot.

 

[artificialist]

I would never use conventional in any turbo gasoline engine, even if the users manual says it is okay.

I have never seen a turbocharged gasoline engine use conventional and never get severe varnish. Changing it every 3000 miles still doesn't prevent the varnish.

I changed the oil in my turbo car at 1200 miles because it allowed conventional in the manual, so I was sure conventional was in the engine.

Change it before 2000 miles and go synthetic.

 

[skip029]

So I emailed the questions to Nissan why they don't recommend Synthetic oil and if I should really wait 1-2 min to allow the turbo to cool down and this is what they responded with:

Thank you for allowing us the opportunity to be of assistance.

Regarding your concern, please be advised that since these statements are not in the owner’s manual we would not make the recommendation to do either.

Also,our engine oil recommendation can be found at page 9-5 of the owner’s manual.

If you have any further questions or comments, feel free to call Nissan Consumer Affairs at 1-800-647-7261or send us another email.

Thank you again for contacting us and allowing us the opportunity to be of assistance.

Sincerely,

Eek! I'm going with Pennzoil Ultra 5w-30, I'm not sure what is up with that reply from Nissan lol.

Wow...fairly lame and CYAish IMO. You cannot go wrong running a synthetic in a turbo due to the heat that is generated. You will be fine running PU; it gives great results.

For the other question--were they telling you not to let the car idle because it WOULD hurt the turbo or WOULD NOT?

I believe they just mean don't let it idle because it doesn't say to in the manual. Don't think they mean it would hurt or help.

Ah...I see, probably someone reading from a "script" to give a stock reply (more or less). If you were running it hard, I would let it idle for a minute before turning it off. Unless I am wrong due to changes in very modern turbos, most turbos spin in excess of 100K RPM and so I would not want to stop the oil supply "suddenly" when the engine is stopped. There are several articles online that discuss this is when the coking occurs in a turbo. If you are just driving around, I do not think it is an issue, but after a hard run it could be. Love that Juke!

Back to OP...I've been away for a while....
My system when buying a new car is to change the oil the first time at half the recommended interval with regular oil, then at the regular OCI and every OCI after that with synthetic oil.
