Esther Oil?

ImportConvert

370Z's tend to run warm. Use a full synthetic instead of that Esther junk, which I believe is a blend. If you';re going to pay $15 a quart, might as well use Amsoil or something.

Per the user manual, Esther is the 'recommended' engine oil to use due the specificiations, and requirements of the Z engine.

Now, if you want to use another brand no will stop you and most likely you can get away with using another brand. But at the end of the day, it's an expensive car engineered to certain specifications. If the specifications call for a special oil, I would rather side with nissan engineers who built the car versus internet forum members who think esther is not worth it.

From a cost perspective synthetic oils are expensive i.e. Mobile 1, Redline, etc. and nissan esther is no different. Personally, all my oil changes done w/ Nissan Esther, and enjoy my car. It's a small price to pay for peace of mind.

Can you please make a scan of this page and post it here? Our 370Z is one of the first in the States and nowhere in the Owners Manual is this stated. The Service Manual makes a reference to Nissan ester engine being recommended, but not mandatory. And what exactly are those "...specifications, and requirements..." that are being referenced? Even Nissan can not answer these questions. We have Nissan employees here at the forum and they have not anted-up either.

Nissan is solely at the center of the propagation of misinformation as Nissan has been nothing but vague and ambitious regarding their own oil, and the Z's engine. To me, if Nissan has an oiling issue at the top-end of the VQ37VHR, then Nissan should have engineered it better or made their voodoo ester available as an additive.

I have been told by friends in the oil industry that the Nissan "ester" oil helps dissapate heat and keep the heat down better than most oils. This may be true but I still run synthetic.

I think it has been determined that it doesn't do that as well as most good synthetics.

Nissan has kept quite on the details on the oil to spook people into thinking it has some magical properties, but any decent oil will do the same job.

The benefit to the Ester oil is it is supposed to react with the DLC coating on the cam follower, and helps prevent the tapping noise you will hear sometimes when you don't run the Ester oil.

Do you know where we can find the info or comparison test you mentioned? Ester is a synthetic, so it would seem logical that the properties are identical with margin gains in lubricating properties. I think it would be to the community's benefit to have reliable scientific data before we jump one way or the other. We all know how easily misconceptions spread on the internet.

The misinformation that comes up with every thread on oil is a killer.


OP, you'll be fine running your oil of choice. There's quite a few threads that can be found on g37 forums that have quite a few UOA from VQ37 that seem to indicate that the Ester oil is a waste, and inferior to a lot of the other oils out there.

Also Pennzoil Planitum has show probably the best and most consistent UOA
