My question was about voiding the warrenty of a new vehicle by not changing the oil per their schedule not about the superior lubrication qualities of Amsoil. Like I wrote before I respect every persons decision to buy and use the products that they feel meet their needs and even though I now go 13,000 miles I didn't until the 60,000 miles was up. Are you?

...actually Squid, I haven't thought it that far thru....not
really sure what I will do?? Since I'm such a waster of
coin, I may just change it every 7500 miles since the way
I drive, it'll take me over 3 years to get to the 7500 mark
anyway! (lol)! And $68 every 3 years sure won't break me,
heck, I don't know what I'm gonna do?.... And, (before you
say it), I do also realize that running the same oil for 3 years
is not cool either.....but, I AM going to synthetic though, no
matter what.......anyway, I will think on it and come up
with a plan of attack. You made a good point....

Squid, I noticed in others forums that a lot of people seem not to wait their warranty expiration to move to synthetic oil. Do you have the same feeling or do you think that most people do like you and wait the 5years/60.000miles?

For my part, I am wondering if I should go for it because right now I am doing 110 kms commute every workday which will bring me to about 30-35.000kms/year.

And, if I am lucky, by the end of the year, I will may do... zero km commute as I could work either from home, going to work by foot or taking public transportation to go to work. At that time, I will be more like Mistergib going more on the time limit more than on the distance limit.

I am in a bad situation where I need synthetic oil now and will care a little bit less later. Can I start my warranty later ?

Another thing, in Europe, usually, some time ago (I take some precautions there), car manufacturers develop their engine in collaboration with an oil company (Renault with Elf, Peugeot with Total, BMW with Castrol, Mercedes with Mobil, etc...). In the same way, oil companies develop their products thanks to their collaboration with the car manufacturers.
So to have the better chance to have the best oil for your engine, the good thing is to go with the oil company associated with the car manufacturer.
In that prospective, do you know who is Nissan working with?

And I would like to have your opinion about the nanofiber oil filter that AMSOIL has developed. Do you think the nanofiber technology will bring something more to the oil filters or that standard oil filters are enough for our needs?

...I'm gonna butt in here, forgive me Squid.....

Squid was not saying to not use synthetic prior to the
warranty expiring, he was just saying not to go past the
7500 mile change interval while its still under warranty, if
by doing so, you would then void the warranty...thats
what he meant....

Now, what follows is my .02 worth....

As for using the oil associated with your car manufacturer,
that doesn't hold much weight with me. Oil is not made
for a specific automobile...you just want to run a high
quality oil of the recommended viscosity and rating for
your climate. This is why one brand of oil can be recom-
mended by several different auto manufacturers...plus the
oil companies like the advertising and probably pay them
for it...

NOw, I'll let Squid weigh in and add anything he deems
important...

Thanks, you saved me a bunch of typing.

Thanks Mistergib. I did understand what Squid was saying, but I don't see the point of using synthetic oil if it is not to use it for its lifetime... which is longer that what Nissan recommends (because Nissan uses conventional oil)... therefore voiding the warranty.
By the way, for us, Canadian, it is 6.000kms or 3 months, which is about every two months for a guy like me.

For sure, it is better for the engine anyway, but the price difference is quite big (... I think. Am I wrong with that statement), and I cannot afford to take a more expensive oil if it is not to use it fully.
You are probably right on this. From what I read, you have way more experience on this field than me.

No doubt, running synthetic for less than its
potential duration raises its costs to benefits
ratio to use, but for us motorheads(me!), the
superior lubrication in both severe heat and
severe cold, and its friction/wear reducing
properties makes it worth it to us(me!)...
..knowing that I have crossed all the T's and
dotted all the I's when it comes to the
mechanical, gives me a sense of satisfaction....
plus, it would take me MUCH LONGER to put
your kind of mileage on mine.

Since you are going to be putting enough miles on
your car that you'll need to change the oil every
2 months, then I would just use a high quality dino
oil.....frequent service will keep it running fine...
Do what coincides with your particular needs and
driving habits....I think that synthetic is cost
prohibitive for you....lets see what Squid has to
say when/if he weighs in....

Hope this helps....

Gib

Once again there really isn't much to add. I used Synthetic from the beginning in the Titan because I planned on keeping it (121,000 miles). Before the Titan I had a 02 Frontier which I knew I wouldn't be keeping so I ran conventional oil and traded the truck at 104,000 miles. With the Frontier I changed the oil every 3000 miles.

While running Synthetic in the Titan I learned a lot and started going the full 7,500 miles as allowed by Nissan. Since I was running over twice as far between oil changes I was in fact saving money because I wasn't changing filters every 3000 miles. Now I run Synthetic from the beginning and go the max mileage allowed per the manufacturer regardless of what I'm going to do after 100,000 miles. (Yeah I drive a lot)

Thanks again both of you, You are a big help from someone like me who tries to preserve his car without paying too much (in fact paying the right amount), and tries to pollute the less possible.

I did not understand why in the US you were allowed 7.500 miles and us, canadians, only 6.000 kms (= about 3.730 miles). That's because I did not read everything.
If you do mainly highways in temperate conditions, you can go 7.500 miles or 6 months in the US and 12.000 kms ( about 7.460 miles) or 6 months in Canada. That is called Schedule 2 in the manual.

Now, that makes more sense: I will take about 5 months to go 12.000 kms and stay under warranty.
Since I am on conventional oil right now, and it is the first oil of the car, I will make do the maintenance at 6.000 kms, but I will go with synthetic oil (or a "false" synthetic one depending of the price) to be able to go the 12.000 kms, which brings the next change at the beginning of the winter.
With a blackstone check at 8.000 kms to be sure not to do a stupid thing, I should be good to go.

Thanks again to help me understand how it works.
As always, I understand fast but I need to be explained many times
