All of these are cataloged as being appropriate for the Nissan 3.3L V6 engine. I use my choices from this list on my 1998 Pathfinder and my 2000 Villager.

I would recommend you find a Purolator Book at Advance Auto and check the one for your car and then go to page 930 in this cataloge and look for another filter with the same diameter, relief setting, and hed size/design. I tried to do that for you yesterday but someone riped off their Manual. I'll try to check it out in the next week. If you don't hear from me- Email me. Old age/forgetfulness must be setting in!!

Is Fram any worse than the aftermarket filters used by the quick change shops? Understand that these wholesale for about $1 in volume.
Some filter application books tell you this: Go to the exact application information listing for your car. Do not rely on a chart (or other source) that shows which filters are equivalent to each other. The information from that chart may or may not be appropriate for your vehicle.
Other than that, their $11.99 special is hard to beat. Wal-Mart house brand oil is Quaker State (until another company bids lower). If you buy the $15.99 oil change you get Quaker State or Penzoil bulk. If you buy the $11.99 oil change you get SuperTech bottled. There have been numerous posts on the oil forums that bulk oil can become contaminated over time. I prefer bottled.
Other than that I don't feel strongly about any API rated SL/ILSAC 3 oil. My only rule in life is to stay away from Fram.
If I want something bigger, I guess I'll have to look at the Purolator book to find a suitable filter of larger size. This filter just seems way too small to do a good job of filtering engine oil on a 3.5L engine.
Actually, I returned 2 of them today. Tired of spending the extra $$ for "genuine" synthetic when I'm unsure of any extra benefits beyond a good conventional oil. For now, I'm sold on Chevron Supreme (but haven't used it yet).
But, once you see for yourself how cheaply Fram oil filters are made and you see that there are better filters out there for the same or less price, I can't see why anyone would continue to use the over-priced, inferior product.

As for FRAM filters. What is the problem with card board ends. If you put metal handels on a paper grocery sack that will not keep the sack from ripping.
joe3891, Times change, cars change. Lubrication issues in modern cars are dramatically different than they were 40+ years ago.

In the machine tool industry there are many wheel around products that attach to the hydraulic oil system to clean oil. They connect these on to the machine for a day and then move them on to another machine. Think of a pump that attached permanently to the oil drain hole, pumped through a small micron filter and back into valve cover. You plugged it in over night every once in a while. It even pumped out your oil at change time. Any takers?
The modern oils are better, engines still have 185 degree thermostats, and i think someone help me here - main bearing clearances are about the same - what in 60s ? - say 0.0005 ???
I use only good (non Fram ) oil filters but I wonder about the VW screens - when did VW go to filters and why?
What kind of differences can the mounting angle have? Should I be using the same Pure One filter on both a horizontal and vertical application?
I seem to recall something about the mounting angle and the type of drainback valve being important things to consider together, but I'm quite fuzzy on this and unknowledgeable about these things in general.
So, if you have a clean well running engine the filter may be nothing more then a anti drain back valve and a bypass valve but the filtering part of it is pretty much useless. So, if we talk about quality filters maybe we shuld only look at the valves, the paper may turn out to be useless.
Comments?
That is the very reason I personally would never consider an extended oil drain as the synthetic crowd seems to think is OK. OIL GETS DIRTY, AND MUST BE CHANGED. On my drag race VW I have a high dollar OBERG oil filter. This is a filter that has a screen mesh that you take apart and clean and use again. You can look at all the dirt and metal shavings to see what is going on inside your engine. When I build an engine I will run it 5-6 minuets on the first start up then drain the oil and inspect the filter screen. It would shock you how much crap there is after only 5 minuets on a rebuild. With this OBERG you will see every red thread that came from the shop rags you use to wipe your hands and clean those parts .
One has to build up a level of trust regardless of what product you use, of course, the easiest way to go is 3000 mile changes and use whatever.
Filter does not take those out.
I like to replace the oil tho if I was in a very cold climate I would use syn.
As to acid, define acid? Are you looking for a specific test result here? My TBN has always been fine and the TBN is a measure of the oils ability to combat acid. Thus, in my experience neither of the factors water, or acid has been a problem. Of course, a synthetic TBN is around 10-12 whereas dino is in the 3-6 range, a significant difference
We put a lot of short haul mileage on these vehicles, and acid resulting from water accumulation under these conditions must be considered.
I can change the oil AND the filter three times for the cost of one analysis, thus nullifying that option as a waste of time and money.
people say well 3000 miles works, well 1500 miles used to work too.
I've always though that the long drain intervals called for in Europe have been driven by their fear of vast amounts of waste oil. It's not the first time an industry has been burdoned by questionable pro-envirnomental science.
A drink of 5W20 anyone? >;^)

-if Jiffy lube wants 3k changes that prob too low for greed reasons
- i think we need more pro environmental regulation - not less - I was sorry to see the congress not improve the CAFE gas mileage standards - Detroit and all the texas oil men want everyone in a 14 MPG 5000 pound SUV. It uses up my grandchildrens gas.
