Took to Dealership - Royal Purple
 

So I took the 370 to the dealership because of a P0305 SES light.
(Cylinder 5 misfiring). I just got a call from the technician, he asked me what kind of oil I am using and when I installed my Stillen Gen3s.

I told him November for the install and Royal Purple for the oil.

He informed me that Royal Purple is not ester oil and can/will **** up the cylinder heads.

Is this true and what am I facing now?

IF things are damaged am I responsible and/or void my warranty. Im waiting for him to call me back after he looks into it further.

no because Nissan only Recomends Ester oil, not required at all. and my freind has an SI, even though those dont require ester oil, my friend said his ride isnt as smooth and the royal pruple burns really fast.

Tell him to put up or shut up....

You could not have voided your warranty with using Royal Purple.

In addition, Cyl5Misfire is not related to your oil...

Nissan is imfamous for finding ways to get out of serious warranty work.

Im not certain, others can chime in on this, but does royal purple have ester in it? I know it meets all the oil standards, saw that in another thread way back.

BTW, I don't even think that when you take the car to do an oil change at the dealer they can prove to you that they are using that type of oil.


Here is at again, they have to prove that it cause the problem.

Magnuson?Moss Warranty Act - Wikipedia, the free encyclopedia

Magnuson-Moss Warranty Act

MLM Law - Lawyer Grimes & Reese PLLC - Attorney Specializing in Multilevel Marketing - Understanding the Magnuson-Moss Warranty Act

it doesnt matter if it is or isnt, Nissan doesnt require it, not using ester oil will not void warranty.

Ugh... MMA isn't going to protect ****. It never does.

99% of the time it's easier and cheaper to just pay for repairs out of pocket and not waste your money on legal fees and your time in the courtroom.

That said, as long as you are using an API certified oil as specified in the owner's manual the oil isn't the problem. You can just show that page to the service department if they throw fits about it.

And now they will say the intakes caused it. Google and do your DD before you go back to them so they cant bully you about stuff you dont know. The internet is our best friend for things like this.

My guess is if the problem is something serious they are going to blame the G3s.

If it's something minor like a bad spark plug they might not bother messing with you.

The car drives fine, it doesnt seem like anything major. Just the SES light worries me.

You need to get a feel from your Service Manager about mods and warranties before you bring her in. When I was getting my oil changed I was talking with the SM and asked about the GTR and what I had heard about voiding this and that and got a good feel for how he goes about warranty work and mods.

Cyl 5 misfire huh...what kind of gas are you using? 91 at least?

Maryland too, I see. What dealership? Just seeing if its Tischer in case I need to drag mine in anytime lol.

I have been running royal purple for the past 6 months, with no issues..But i have read reviews about RP not being good for VQ engines.. then again i also read that aliens landed on Roswell.

Could be bad fuel deposits on that one injector, or a bad park plug all, normal things.

Yes Premium always, and the dealership is Criswell in Germantown

Im surprised they'd try to lay blame on the oil versus the intake first...anytime you muck with the MAF you might be in for trouble...

Cylinder misfire
 

I had a SES light come up a few months back. The tech had to talk to someone at the factory because he couldn't figure out why it was a code for a misfire. My car is a manual w/ sport package and no mods (just AMSOIL). He said only one other 370 has come in with this misfire and from what we could figure it was from tagging the rev limiter. It made sense because I do stretch her out from time to time. One thing I remember was that the idle settled @1,000 rpm with the SES light on and went back to its normal 650 rpm idle after the code was cleared. I've put about 1,500 miles on the car since the code was cleared and have been trying to shift right when I see the light come on. So far so good. I don't think Royal Purple would hurt your engines' top end, but if you want a synthetic with esters AMSOIL and Redline might be worth a look. BTW I have @ 11,000 miles on my Z.

***UPDATE****
Just talked to the tech again

They are saying the oil and Carbon deposits on the throttle body are causing the P0305 SES light.

They want to do a fuel service cleaning, don't think I am saying it right but they say that it is done about every 15000 miles. Is this true and should I get it done.

They also want to replace the passenger side cabin filter and do the flush but its expensive like 175... Is it worth it?

I have had the SES light come on four times since i got the car in Nov. The first was at 80 miles on the odometer, random misfire (P0300), and i just had it cleared thinking it was a fluke. The second time (80 miles later) took it into the dealer, they dismissed it saying it was working the "kinks" out of the system or something. Didnt really believe it, but thought maybe some fresh gas (the tank was full when i test drove it) would help. It was about 1500 miles later and came on again, the dealer did an idle air relearn procedure. Then about 400 miles later it came back on. This time they kept it for two days, and working with Nissan Tech support they replaced both MAF sensors. They had noted that it had been running rich, and this had taken care of that, and I believe that will actually solve the issue.

Everytime the light came on as a random misfire (P0300) and it was after the car had sat overnight or all day will I was at work (8+ hours) and came on during the initial startup. Only time will tell if this really takes care of it, I have about 400 miles on the car since the MAF sensors were replaced, but I feel more confident since they actually replaced something rather than just resetting the ECU, and that it took care of the running rich condition as well.

I dont know if something like that could trigger a specific cylinder misfire, although if it is related to the MAF sensors, they intakes would be a very easy scapegoat.

Simple deduction says that the intake is filling the other two cylinders on that bank just fine with air, therefore there's no reason it would omit filling the misfiring cylinder with air...

Intake has nothing to do with a single cylinder misfiring. I'd wager it's the coil on plug for that cylinder or the controller or a plugged injector.

I wonder when they'll say you have to use Nissan Brand Gasoline?

Total BS. Contact Nissan and tell them the dealership is screwing with you. That or take it to another dealer.

All Nissan dealerships LOVE warranty work. There is nothing in the service manual that states that one needs a fuel service cleaning every 15K.

The throttle body has nothing to do with a misfiring cylinder.

:facepalm:

If it's under warranty tell them to fix it by whatever means they have at their disposal/cost. Or, go to another dealer for a second opinion. You can do without the cabin filter for $175.

From what I found months ago, Royal Purple is indeed an ester based oil. That is why I decided to use it in my 370Z and have been for 7500 miles without issue. 2 track days and lots of daily abuse. I doubt the type of oil you used was the issue.

Semi-off topic but I thought I'd throw it out there. For maintenance, or to correct MAF deposits from an over oiled (oil based) filter (like what they may use on aftermarket intakes) there is this stuff:

The guys on the M3 forums who had some higher mileage cars reported noticing a difference after cleaning FWIW. Maybe it's something to consider after you service your filters to avoid possible codes later?? Again just thought I'd throw it out there.

anyone else use this:

every 6-7k miles?

And really? Carbon deposits on the throttle body? The one thats always open seeing as our valves themselves are the throttle body?

That's my point.

Carbon will never deposit on a throttle body...ever...(OK, exceptions: if you have blown valves and are backfiring through the intake or a really bad crankcase blowby issue with smoke billowing out your PVC hose, even then that'd be more like smoked oil/soot deposits not carbon build up)

Have them change your tailight fluid and muffler bearings while they're at it.

On an old 240SX I had there was some build up around the throttle plate that was affecting idle. It was more like dirt though, not sure how they are calling it carbon...

go buy a can of BG 44k, that should clearn ur engine up

I used the MAF cleaner all the time on my turbo car as they do get some coating on the MAF sensor wire itself and that stuff cleans it good.

They wanted to charge me $108.00 to reset the code... Really...

All we have for premium up here is 90, pretty damn weak.

Clean injectors before an oil change
 

The chemicals in most cleaners can seep into the oil and given that it breaks down oil deposits and such it can do the same to the oil. Many recommend that if used, it should be used a couple of tanks of gas before you drop the oil. Can not say if they are right or wrong but seems worth running a couple of tanks of gas just to be sure that any "add to the gas" solvents are out of the tank. Obviously, if the engine is tight then there is less chance of the solvent getting into the oil...

take it to auto zone

Nissan will ask for an oil sample and test it, if it gets to that point. We see this all the time when people get there CVT's serviced at independent shops and they put regular tranny fluid in the CVT....then you hear pop.

'09 does not have a cabin filter. Tell him to show you the core.

LOL...air filter

He is the one who said cabin filter. Only responding to info as presented.

:iagree: :icon17: That's what I was thinking too...
