Okay. Today I gotten my first oil change using Ester oil at my local dealership.
First oil change was free, but since Ester is consider premium I paid the difference. Price of the oil was about $12 a quart, total of five quart.

I will let you know if I notice any difference thru out the months ahead if this oil does any wonders.

 

In all honesty, don't get your hopes up.

 

Just curious, What differences are you watching for and how are you going to
measure them?

 

if you bought the car, go with ester oil for longer engine life and better performance; if you leased it, save your money for something else; besides alleged mechanical advantages of the ester oil, you have to be in tune with the car, meaning drive a stick or in manual mode all the time to feel the true difference between ester and regular oil; so if you love the car and bought it, go with ester oil and enjoy the ride.

 

That's ridiculous.

 

This is the biggest crock of **** I've ever heard in my life...and I worked in an ER and have heard some humdingers. OIL IS OIL IS OIL. Anyone who tells you you can "feel" a difference between Ester and synthetic and conventional is a crooked, lying S.O.B.

 

I've had the ester oil change performed three times and the only difference I've noticed so far is a lighter wallet!

 

stick with synthetic group 4. Advantage... better lubrication, but mainly longer time between oil changes.

I run mobil 1 5w30 in my 1114rwhp z06.... guess what, if it's good enough for that, it's good enough for your g. Anyone else who tries to argue that is a victim of marketing.

 

I do not think that is a Group IV.

 

Nope it's a group III, thanks for the catch as I meant to say, "stick with a group 3 or 4".

 

Good question. I guess I can only compare with whatever oil it came with and what others are seeing.
I heard some ppl say they saw improvement in gas mileage. Smoother and quieter engine. So I will be looking out for these.
I did notice engine is quieter than before. Not sure if this is because of new oil.

I told my brother who is a mechanic I got me Ester oil, he yelled at me for wasting money.. Told me to use cheapest oil I can get. Haha.

 

So what kind of oil do you use?

 

Good response, thanks. I also use Nissan Ester, but only because
Nissan gave me a three year service contract after giving them
some extensive feedback on their "recommended use" of their
oil. If I still own the car after three years, I will be switching
to Redline.

There is plenty of convincing documentation as to why "ester" is
recommended in the VVEL. The VVEL has some incredibly tight
tolerences and generates heat very quickly. The nano-technology
in the Nissan Ester oil really does a great job of reducing friction
and the resulting heat in the VVEL system, but I have doubts
about the ester content and base oils used in it due to it's
proprietory formula being unknown except for what is available
in Nissan's "white papers". Ester bases are far superior to other
base groups...it's polarity causes it to flow towards heat instead
of away from it like other base groups. It's polority give it a
lingering and sticking property that provides superior pressure
build-up as compared to other base groups. Ester will
naturally flow into much tighter spaces than other base
groups. Since ester molecules "seek" contact with the metal,
it provides superior protection from varnish and sludge formation
that over time, other base groups will just flow over.

The VVEL throttle is driven by a motor-actuator mechanism
that regulates the intake valves......as compared to the previous
variable valve systems that responds to a "butterfly" valve
first. The speed of oil pressure building in the drive spool
has direct effect on "throttle response" in the VVEL....it's
an entirely new mechanical concept. Simply put, ester builds
pressure faster, allowing faster valve reaction in the VVel.

What I don't understand is why people with no understanding
of Tribology other than "this is what I use" or "my brother
the mechanic says" feel they need to chastise and make
ignorant negative comments to people who chose to use
Ester oil. I can tell you this...more and more VVEL owners
are switching to esters according to what I'm reading
on the various Nissan and oil forms after they've had
"limp mode" and premature actuator failure and noise
due to VVEL heat issues......Marketing pressure or
educated decisions???? Hey it's your engine, use
what you want or can afford, but do some homework
on why Nissan developed and recommends their oil
for the VVEL rather than telling people it's only
about marketing.

 

I personally use Pennzoil Platinum after reading remarkable reviews of the oil. SOPUS uses a fantastic Shell base oil for Pennz Platinum and there have not been many negative reviews or bad used oil analysis reports. I tell ya what, if my engine ever starts getting the VVEL tick (which sounds like a small Apache helicopter) or my engine ever goes into limp mode, I'll switch to Nissan Ester. Until then, I'll continue using Pennzoil products. I've even considered going back to Pennzoil yellow bottle conventional. I've had no consumption issues, no tick....nothing.

 

Knoxville'.....Good choice. I'm seeing lots of
the new 3.5 and 3.7 VVEL owners getting great results with
PP as compared to other brands. I'd bet it (PP) has more
than enough of the amount and kind of ester additives that
the VVEL likes to stay happy. It would be great if we only knew
what's in it (the PP). Have you done any UOAs yet? I really want to
see some pictures from under the valve covers of hard driven
"Z" VVEL motors after 40K miles so we all know which
oils are "cooking-on" to the hot parts.
How many miles do you have on your G?
I'm guessing there will be alot fewer noise/limp mode/heat/oil
discussions in about a year as we all find out which oils
really work best in the VVEL. Thanks for the info and good
luck with the PP.
