And it has happened that some have closed their service bays because they aren't getting enough warranty work. So I'm not sure your explanation above holds water with a lot of dealers.
Believe me, Dealers do not like to help customers who dont service through their dealer..why would they? When I talk to Service Managers the first thing that usually comes up is the customers loyalty to the dealer and I may push to help some customers but the dealer plays a part in assistance and I am talking about customers who call in when they are out of warranty looking for help or were denied warranty due to lack of maintaining vehicle, the dealer is going to push for a customer who is loyal vs someone who doesnt service through them and all receipts for oil changes ect will be needed, If you are not loyal and use aftermarket parts and IRF's you are going to have a much harder time.

It's been my experience (25 years) that dealers are quite happy to get money from where ever they can. Loyalty, while on the surface "looks" important, is not the be-all/end-all of business practices. Especially when dealers charge outrageous prices for their services. People stay away from them. So warranty work can, and is, the bread & butter of a lot of dealership service departments.

Warranty work is done at less of a cost vs a normal repair where warranty prices are not used, the Manufacturing company pays lower labor and the part is paid at warranty cost without the markup, sure it is part of doing business, but dealers do not rely on just warranty work, the point here is, If you dont service through a dealer and only bring warranty work, the dealer most likely wont stand behind you. period! I should know, I do work for a warranty claims center lol

That's not right! Warranty work is charged to the manufacturer at full cost (labour & parts). My local GM dealership absolutely loves warranty work. They make the most profit on it. Now the Manufacturer.... they are the big losers.

Well, I think this is becoming a pointless argument, what my original point was is that dealers love to help loyal customers and they are not as inclined to help with unloyal customers and will make it a lot tougher for a unloyal customer vs a loyal customer. I choose to agree to disagree on labor rates and parts as I know on my side that the parts and labor are performed at a lower rate vs a out of warranty repair

All I can say is the Nissan OEM filter is one of the worse oil filters you can ever use for your car.

They make more money from selling the re-branded oil filter than they spend on warranty repairs from using the substandard filter. This is pretty common in the automotive industry.

I have about 750 miles on my G37 now and I was thinking of changing the oil for the first time. I've always wondered what an OEM filter looked like inside. I had some free time today and decided to find out.

I visited my local dealer today and bought myself a 15208-65F0C, the stock-sized filter specified for a 2008 G37. The guy at the counter said it's the same filter used for the G35. It costs about $7/ea.

I had an extra Purolator oil filter at home. It costs about $3 (sometimes $0.01 after rebate) and is readily available at PepBoys.
NOTE: The Purolator oil filter I used is L14610. It's the longer version of the L14612 which is listed on the Purolator website as the oil filter for G37s.

Here's some pics:

The Purolator filter is larger than the OEM filter


Now it's time to cut these open! Prepare to be shocked and disappointed.

NOTE: For those of you who've read about oil filters, you probably know that Fram has the worst reputation amongst widely available oil filters. They tend to have flimsy cans and, most disturbingly, their filter elements are made with weak cardboard end caps that can collapse or fragment in hot oil. Good filters, like Mobil 1, Purolator PureONE, and K&N are made with heavy metal "skeletons" that will neither collapse nor break down in hot oil.

OEM filter cut open (I immediately noticed the cardboard endpiece)


Everything inside the OEM filter laid out

Time to open up the Purolator

Close up of the Purolator's metal endpiece


Side-by-side comparo of both filters (Purolator on the left, OEM on the right). The Purolator filter element is approx 2 1/2" tall with 50 pleats vs the OEM filter element which is approx 1 7/8" tall with only 41 pleats. More pleat area = better filtering ability.


Filter top


Filter bottom


Anti-drainback valve (Purolator is made with a thicker, better quality rubber. OEM was thinner and felt flimsy)


Bypass valve


So what did I learn from all this? Pretty simple... the OEM oil filter is basically a Fram in disguise. Will I ever use one in my G37? Probably not.

Also note that the Purolator filter that I used was the PremiumPLUS filter. Purolator also makes their top oil filters called PureONE, which costs more ($5-$6). The PureONE filters are even better than the PremiumPLUS Purolators. I'll try and open one of those too when I get a chance.

So what's the best oil filter to use in our cars? You can't go wrong with any of these:

Purolator PureONE
Mobil 1
AMSOil
Bosch
K&N
Napa Gold

If you wanna save some money and do regular oil change intervals, any of these oil filters will suffice. Hell, anything's better than a Fram/OEM Nissan oil filter.

Purolator PremiumPLUS
SuperTech
STP
AC Delco
Valucraft (Autozone brand)

I've heard good things about the $2 SuperTech oil filters at Wal-Mart. That may be another viable option. I gotta read up some more and maybe cut one open. I plan on doing my first oil change in a couple of days.

Anyway, hope this post was informative for you guys.

Happy motoring!
