+1 This thread is confusing. Why does oil have to be so confusing? I have thought about Motul 300V but I also like longer changes. I don't drive my car very hard too often and have a 7 mile drive at 35 mph everyday to work. I do some spirited driving but not that often and mostly on long trips. I have always used Mobil 1 and have gone 7,500 or longer with little trouble. I guess I will get mine tested after the next change to see if everything is OK.

Yep, that's dumb. We all know only a K&N will do that.

slicker oil = less friction = less power 'robbed' by friction = increased engine output. (less drivetrain loss)

slicker oil tends to correlate with protection, coincidentally.

Slicker then sex lube but not 20hp.

Ill take that bet, but the taker has to let me use his/her car for the comparison
since I'm going to ruin it with straight 0 weight oil to prove I can get an
20 additional HP as compared to whatever is in it now.

Thinner viscosity doesn't mean slicker.

Mike, define "slicker" please? Liquidized graphite is slipprier than any petroleum oil
on a clean dry surface, but I would't put it in an engine. Straight parrifin would
probably provide maximum power output from a gas engine once it's liquified
but I wouldn't put that in an engine either. My point is that motor oils all have a
surface coefficient of drag against moving parts...otherwise there would be no
adhesion/surface tension to keep it between the moving parts. Generally lighter
molecular weight will provide the least resistance from motor oil in a recipricating
engine. Nissan published a HP increase of up to 1.5HP per cylinder
using their Ester...but didn't provide comparison data other than
the comparison oil meeting the required oil specifications for the engine tested.
I would guess they were comparing a "major label" synthetic since in theory that
would produce the greatest amount of drag due to longer molecular chains.
Remember that synthetics have longer molecular chains than conventional oils and
thus provide longer service but are not one bit slipprier than conventional oils .
It is a myth that synthentics are slipprier or slicker than conventional oils!

I would guess that an increase of up to 3HP per cylinder could be
achieved in a stock G using the lightest weight Ester racing oil as compared
to standard synthetic 5-30. But like I said in my last post, the challenger
will have to provide the car because I'm going to shorten it's life proving
it. Second point....oil is for lubrication, reliability and protection, not an
accessory for increasing HP.... UNLESS you are a sponsored drag racer who
rebuilds the engine every several runs.

I could strip out a car and get an increase in mpg but that's unreal. Let's talk about real numbers in real world everyday driving. You won't get 20hp increase imo. BTW are they now making an Ester racing oil? I'd like to see the price of that gold in a bottle.
Now tell me if I'm wrong which I most likly will be but didn't they come up with this nissan oil because of a tick and now it should be used because it's just a great oil? Did nissan have this oil pre tick or post tick? I'm just ask'n.

Point taken and agreed on! Redline makes several specific
ester racing oils that I'm familiar with for less than $12/quart...
not exactly "gold in a bottle" compared to Motul, Amsoil,
Schaeffers, RLI, etc.

Which came first the chicken or the egg?...
the Nissan Ester or the Tick? Purely speculation, but I would bet
Nissan knew they had some lubrication challenges when they
developed the VVEL and recognized the chance to kill two birds
with one stone....lubricate the VVEL well and increase fleet mileage
while reducing oil pollution. They did it, people can argue it all they want.

BTW for all you Nay-sayers...google "Kendall + titanium" and
look at their published claims of decrased friction using their new
"Nano-oil" using titanium as an additive. They're making much greater
and almost unbelieveable claims in friction reduction with their oil as
compared to Nissan's claims. ???will it contain enough of the right ester
compounds to satisfy the VVEL??? ?? Will it even need the esters
to satisfy the VVEL???

But not all have the tick, right? If true, why?

Lots of speculation and circumstantial evidence, but you can be
pretty sure that Nissan is gathering lots of data and won't share
it! Some say faulty parts in early production runs, but that can't
be entirely true because it's still happening. Lets face it...some
folks who buy a performance machine are going to run the ****
out of it, and no doubt that has caused actuator and actuator
motor failure. Nissan engineers have inferred that revving the VVEL
over 3k with no load (in neutral or park) is a major contributing
factor to the tick. How many twerps do you think do this
regularly???? And no doubt some folks are just using the
wrong oil and doing all the above.

Yep on all above.

The HP increase is proportional to the output of the engine, and 300V has been proven for years on motorcycles that it WILL increase output roughly 6-8% over a conventional oil.

That being said, Mobil 1 is also known for "low hp" output. The video is using two extremes.

To be honest, any high quality oil will give similar results in hp gain as the Motul, some more than others based on the formulation. I do happen to have some before and after dynos showing that 300V does have "less drag" than 8100, which has less drag than Valvoline full synthetic, which has less drag than the factory fill, all on my own car.

The above statements would all be with the same viscosity.

As for the Tick, the oil was originally formulated back in 2005. Was VVEL around then in prototype stages? Who knows.
