It IS manufactured in china, but so is 92.7% of what you own. Including most of your Chevy's parts. It isn't a low quality filter. Never in 6 years as a tech have I seen a Nissan filter fail. But that is why there is such a big aftermarket. If people are convinced by someone that a certain product is superior, they will use it. I will always use Nissan filters because they are free for me.ken in az wrote:It has been said the nissan filter is manufactured in china and is on par with the cheapest fram filters.
Size means nothing. Its all about filter operation and design.Double E wrote:I've always been fascinated at how small nissan filters are. That there's a larger option seems a no-brainer. I believe the filter that fits the first gen (03 & 04) M is the same as I was using on my old I30 and it was small to me.
That's why you have to include an oil analysis with any extended drain interval.M45Runner wrote:As far as those 25k miles oils, I really don't have any confidence - it will break down, which is based on time. So, I will stick with my 5k mile change interval.
Actually, Infiniti uses Chevron brand, 5-30W, 55% synthetic oil. At least thats what Riverside Infiniti uses in all of their cars when they do an oil change. It is what they recommend too. So the oil is at least part synthetic.ken in az wrote:N Our FSM and Manufacturer do not recomend Synthetic oils either - why is only speculation - but my theory is that with synthetics these nissan engines will run for so long the service interval would be so large you'd be waiting 15 years before you need another car - so call it Nissan's way of getting you back for another car - lol
One of the other reason that it is better off using regular oil (syn. or not) and change it every 5-7k is: The engine will use some oil - it will use more if you push it harder.ken in az wrote:

I would bother with it if I had $$ to burn - but proper drain intervals on current synthetics available off the shelf are just fine and in some cases overkill - but you pay for peice of mind and convinience - all about the cost/benefit ratio
