When I first bought my truck, the dealer said that if I do my own oil changes (I do), that ONLY Nissan filters should be used. He said it keeps the oil high up on the engine for better starting.???
Sounds strange. I've been using Bosch filters since I used up the two Nissan ones I bought. No problems.

Thoughts?

Most of the aftermarkt oil filters dont have the check valve in them. This keep the oil from completely draining back into the oil pan.Makes it easier on the eng on startup.

Tell him to pass you whateva he's smokin'....sounds like it's good stuff.

The fram tough guard filter has the anti-drain back valve, as do many quality oil filters.

Here's a question, since the oil filter on the Titan points toward the ground rather than toward the sky how is the oil going to drain out of it?

There must be some kind of vacuum or siphon effect after shutdown in order for that valve to be necessary.

Here's a question, since the oil filter on the Titan points toward the ground rather than toward the sky how is the oil going to drain out of it?Its not just the oil draining from the filter. From the filter the oil goes through passageways to all the parts of the engine, including the timing chain tensioners and to the overhead cams. Without a check valve in the filter oil can drain back down from these passages. Then when the engine is started there is no oil to these areas for a few seconds until the pump can refill everything.

The anti-drainback valve is only designed to hold the oil in the filter. This is directly from Fram Car Care FAQ:

"Anti-Drainback Valve. Some oil filter mountings may allow oil to drain out of the filter through the oil pump when the engine is stopped. When the engine is next started, oil must refill the filter before full oil pressure reaches the engine. The anti-drainback valve, included in the filter when required, prevents oil from draining out of the filter. This anti-drainback valve is actually a rubber flap that covers the inside of the inlet holes of the filter. When the oil pump starts pumping oil, the pressure will unseat the flap. The purpose of this valve is to keep the oil filter filled at all times, so when the engine is started there will be an almost instantaneous supply of oil to the engine. "

Personally, I've opted for the TruFilter woven steel washable/reusable filter. It filters better than paper filters and flows so well that it eliminates the bypass valve at startup. It also has a rare earth magnet at the tip to catch any metallic particles down to 35 microns. A few drawbacks, though. I got a show special for $90, so it's going to tak me around 20 changes to get my money back. Also, I'll never be able to get lazy and take it to somebody else for an oil change. But, I think the end result will be worth it.

Thanks WYSIWYG because I have a lot of pictures of oil filters I've cut opened for another site and I know that to be true.

am I still smokin something?

You know it's good when you don't remember smoking it. HAHAHA, I think.

Fram and quality do not belong in the same sentence!

That is beginning to look very true.
Found this letter supposedly from a Fram (Allied Signal) engineer to someone
doing an oil filter study. Remember it came off the internet, so..............

"Russell,
I obtained great satisfaction from reading your oil filter survey.
I worked for two years as the oil-filter production line engineer in
an Allied-Signal FRAM facility and I can confirm every bad thing you
have said about FRAM automotive filters. That's from the horse's
mouth, as it were.
I'm also a quality engineer and can confirm that FRAM applies no
quality control whatsoever to any of the characteristics for which we
buy oil filters. I frequently saw filter designs which were barely
capable of meeting J806. Many of FRAM's designs will block and go to
bypass after trying to filter very little contamination. There were
often leakage paths at the paper end discs when these were not
properly centered on the elements. Some designs had the pleats so
tightly packed against the center tube that they would block off in no
time. I had discovered that the FRAM HP1 that I had been buying for
about $20 Cdn was EXACTLY the same as a PH8 inside - the only
difference being a heavier can - no advantages in flow capacity. The
paper filtration media was of apparently poor quality and the process
of curing the paper resin was very inconsistent - elements would range
from visibly burnt to white. FRAM's marketers admitted that there was
just about no way the public could ever prove that an oil filter
contributed, or did not prevent, engine damage. The only thing FRAM
tested for was can burst strength. Another problem that they have from
time to time is in threading the filter base - often there are strands
of metal left behind on a poorly formed thread.
I have not used a FRAM filter since I started working there. Their
claims are entirely and completely marketing bull****.
If people really want to protect their engines, a good air filter is
vital (which excludes FRAM from that list as well) and a combination
of one depth and one full-flow hydraulic filter, together in parallel,
will do the job of filtration to perfection.
Thanks for doing a great job in trying to get the truth out! You can
quote me anytime.

i have to agree fram filters suck!i have a friend who imported an rb26dett for a 240 project.got everything buttoned up the fram filter he used collapsed on the inside and starved the engine for oil destroying it on the dyno after 3 pulls.

Here's a question, since the oil filter on the Titan points toward the ground rather than toward the sky how is the oil going to drain out of it?

This is a GREAT question that has yet to be answered to my satisfaction. I find that many service managers don't know what they are talking about or are regurgitating facts from someone else who doesn't know what they are talking about. I could see great benefit in one of these anti drain valves in engines with the filter on the upper part of the engine, like a few Toyotas I have seen.

Hmmm POS cardboard end plates, must be a Fram filter LOL!!

The next time I change my oil and I pull the Ultra filter off that doesn't have an Anti drain back Valve I'll take a pic of the amount of oil still in it.

By the way my 02 Frontier with the 4 cylinder had the oil filter up high on the side of the block. Talk about a pain to get to. I love this truck!

so what is a good filter? are MOBILE 1 filters good?

Has a anyone tried the K&N oil flters or heard anything about them? I dont really hear much about them. Dont know if that is a god thing or bad

I use the K&N never had a problem.I like the fact that there is a 1"nut on the bottom of the filter, makes taking it off easy.

This is REALLY off-topic but I don't agree with your sig. There is NO WAY you are going to "punish and enslave" a Subaru STi.

Oh i Know, I was talking about an STI. I already got murdered by one. But what about a van? Jks... that is the first car i came up with. I am still going to modify my sig. I don't like all those cars anyways...:D

Has a anyone tried the K&N oil flters or heard anything about them? I dont really hear much about them. Dont know if that is a god thing or bad
the guy told me that the K&N uses more oil. thats about what i got. but yea, it hasn't been given me problems.

Oh i Know, I was talking about an STI. I already got murdered by one.
I was gonna say that I used to own an STi and I DESTROYED a Titan, with 3 other people in the car. LOL

although,i believe that Toomnymods can beat one. I saw a STi do a 14.5. is that normal?

Well I ended up buying the Mobil 1 oil filter since I use Mobil 1 oil anyways and I was talking to one of the guys at Advance and He said the Mobil 1 filters better than the K and N. Now is there anyway to put a biger oil filter on our trucks cause I dont like how small they are.

The Nissan filter are good filters. Stay away from Fram. Wix (Napa Gold) are also top notch.

I've have run K&N oil filters on my past three trucks with no problems. The 1 inch nut on the bottom is a life saver on a titan. I made up new cuss words tryin to get the Nissan filter off with the crap wrench we have at work....filter was to small or the wrench was to big however you want to look at it. The K&N filter looks bigger than the Nissan, but I have no idea about capacity. My lawn tractor has just about the same size oil filter. I just don't see how this can be efficient.

I've been running an Amsoil filter. Can't beat their stuff, this filter is good for as long as the oil is (25,000 miles), not that my truck will ever get close to that between oil changes.
