I have no idea where he got the idea of Mobil 1 as being the "other" acceptable oil since it doesn't have any Ester at all in it (Class III only).

I talked to my dealership and they said in all the G37's (our VQ37HR engine) the only time they've used the Ester oil is for the TSBs - never had a single client do an Ester oil change in the last two years.
Keep the reciepts if you must for warranty, and DIY.

They can't hold you responsible for DIY oil changes short of it being obvious, such as not putting in a drain plug or too much oil.

Also, Ester is not a requirement.

Find another service guy or DIY. In any case, as long as you use oil that meets the API requirement listed in the manual...you're fine. They can't void the warranty for using oil that isn't Nissan's oil.

That *is* in direct conflict with the Fergusson-Moss Act, and it's intended use...to prevent dealer tie-in sales and requirements to keep a warranty.

Ford Truck requries Ford Oil, and must be performed at a Ford Dealership to maintain warranty.....for example

There are a number of people here who have used non-ester synthetic oils that seem to be ok.
"Seem to be ok".. That is the issue. How do these people know if all is ok without tearing down the engine ans using a micrometer etc to determine if all is truly ok. I think Ester oils have a higher heat stability than other synth oils and that iswhy nissan specs them.
BTW, you buy approx 35,000 dollar car and $100 is going to break you? that is stretching the budget?

I use an iPhone app called GasCubby to keep track of all of my maintenance. easy to use, exportable to Excel, etc etc etc.

I'll make a thread about it tomorrow or something.

Oil Change
 
Redline ester base oil change on tommorow's to do list. I ordered a case of Redline oil from Carquest. See AK oil change for details on ester base oil. If your interested on how to do a oil change, diff fluid change PM back.:tup:

P.S. How's does your Kenwood HU sound?

No, Nissan spec's *their* special oil, which has esters added, and some nano-carbon particles that they think makes it work better with the coatings on the eccentric shafts, and charges $11-$14/qt for it. Actually, they don't spec it, they recommend but do not require it. Just like Ford will recommend you put in Ford oil (if they still have it)...

Mobil1 is good up to 400F. Our cars are well beyond limp mode at 400F.

Well, if it wasn't OK Nissan would explicitly state in the owner's manual to only use approved Ester oils. It doesn't, and to my knowledge there are no TSBs recommending only Ester oils.

There is one regarding replacement of the VVEL system components...or maybe it was the ECU - or something to that effect. It requires the techs to remove the customer oil and replace it with Nissan's oil.

That, I'm sure is related to their testing, and establishing a very common foundation between their test environment, and what the mechanic will do - in otherwords, if they don't do it, they can't guarantee the results simply because they haven't tested it with other oils.

Makes sense...from a scientific standpoint.

Huh? How did you dream that up? And they do now offer an oil cooler...

There is a Nissan TSB that says to use Nissan's Ester oil when a customer is complaining about excessive valvetrain noise. Nissan also has a bunch of marketing verbiage as to why everyone should be using their Ester oil, but the only real practical reason that they seem to have is to reduce valvetrain noise, not to reduce oil temps or eliminate the need for an oil cooler if you're tracking your car.

The service writer at the dealer said that they were getting complaints about oil temps and that the Nissan recommended ester oil should make it run cooler so i changed the oil, my oil temps are between 220-240 never been on the track, dont know what was in the Z originally but started using their ester oil at 700 miles and change it at every 1500 miles after that. have 5k on it now, oil temps are still the same, is the cooler made by nissan?

These service writers NEVER cease to amaze me with their "new lines" :shakes head:. This ester oil has NOTHING to do with the engine oil temp. As per Nissan, the valvetrain noise is reduced when this oil is used. Though, a good synthetic oil will always have Superior high temperature stability and may even let you run a little cooler. But Nissan's "magic oil" isn't even synthetic. If I recall correctly, it's regular oil with ESTER additives :rolleyes:

:iagree: ester oil not only costs more, but is a 3k mile oil :shakes head:

Redline is good for more than 3k.

vipor 12-29-2009 08:45 AM
all synthetics (class 3 and 4) are good for more than 3. 7500 seems to be an average.
