All seem to have really good construction. All seem to cost relatively the same with the Amsoil being the most expensive. Cost isn't an issue between these three. I'm looking for the filter that provides the best protection. I live and drive in north central Texas. The air here is dusty often due to lack of rain during the summer and from being windy. I drive all my cars hard. They are a 2004 Ford Mustang Cobra with a supercharger, a 1996 Ford Mustang Cobra, and a 2004 Nissan Maxima. The oil I use is Mobil one synthetic but am considering switching the Mustangs over to either Redline or Amsoil. Which filter out of the three will last the longest?
 
Mobil1 extended and bosch distance plus are good fiilters for longivity and price.


I personaly found k&N to be HUGE upgrade from fram/purlator , but from time to time I read on diffrent forums that the filters dont keep in the dirt too well. Not going to buy anymore . I got 5 for aournd 5 a piece so it was [censored] of a deal.

Amsoil never has sales and prices are high unless you have an athentic ride you want to keep for decades i think its waste, but thats just me.

Mobil1 and Royal Purple are more than enough for 99.999999% of people.

Amsoil seems to make a decent filter. If they were easily available I'd use them exclusively however I'm the type of guy who needs instant gratification.
I saw the new ultra from fram today. The filtering media is metal backed to prevent collapse. They seem pretty good,and easy to find.
I stay away from everything mobil 1. I refuse to support them in any way so from the choices you listed it's Amsoil all the way.
They make a heckuva decent air filter as well. I bought a monster cylinder type for my mustang.

Peavey Mart sells some, but whether or not they stock the part for your application is another story. My Peavey Mart has them for my F-150, which would be a serious waste and case of overkill, but none for the G.
 
You might consider staying with Mobil 1 0w40 and either a Napa Platnium or Fram extendaguard oil filters....

or

Amsoil Europeon 5w40 and Amsoil filter if you don't mind UPS delivering to your door!

Why? What's wrong with M1?
 
Thank you for all the replies. Well, I'm lucky then. The quick car lube shop less then a mile from my house is an Amsoil dealer. They said they'd order me whatever I want. I just need to tell them what part number.

What makes the european spec'd oils better than the ones here in the states?

It does not make them better, just a different spec by a European org. Just like Jaso=Japan org. or any other spec specific to an OEM or place of manufacture in most cases.

Less than 10% drivers change their own oil, of those less than 50% paid for M1 or RP filter, most of them bought Fram or Purolator Classic ...

Thats probably what I'll do for the Maxima and 96 Cobra. I forgot to mention that I run RL in my R1 and have a K&N filter on it. That is pretty much what cycle gear has in stock. The last three oci on the 2004 Cobra have had RL also with a Mobil one filter.

On a side note...since your username is FZ1; I assume you have one. Nice choice sir.
 
My opinion is that you can put the RP, the Fram Ultra and the Amsoil pretty much on the same shelf quality-wise, as well as the Puro Syn (there are others too but I don't know them as well). They all have similar specs, synthetic media and construction quality. The Amsoil and Ultra have a little better efficiency than the RP and the Puro.

The K&N and M1 are also good filters but they use a cellulose/syn blended media. That puts them a notch lower in my book because the capacity of those types of media might be lower (it's going to vary somewhat according to application, though and how much media is fitted into the package).

Of the three the OP listed, I would choose the Amsoil. Higher capacity, better efficiency and a full synthetic media.

I would strongly recommend looking at the Fram Ultra, Puro syn or the RP. The Fram and Puro are 40-50% less money than the Amsoil and, I believe, of equal quality. The RP is fairly pricy in comparison but generally slightly less expensive than the Amsoil.

They really are ALL great filters and I wouldn't squawk about any of them being on my rigs... it's just about the cost.

Look at the BT Anchors uoa posts . The various,filters,he used,made no difference in the WM results.

Thanks. It's an '02 Yamaha Racing Blue with Silver frame and engine,about 8,000 miles on the clock.

It's more about the extension of the OCI these days as opposed to improvements in WM. There are differences there too but they are really tiny in normal circumstances and hard to see. The advantages of improved filtration can come into play when you have issues with contamination rates due to problems.. such as a air filtration malfunction.

Also, WMs do increase with dirtier oil but a modern engine doesn't generate all that much. There is a threshold where contamination produces more wear but modern gas engines are so clean generally that even with a longish OCI, the oil is changed for other reasons before it reaches that higher wear threshold. If we were talking the '50s era and the transition from (boulder-catching) bypass-only filters to reasonably efficient full flows, on dirty engines that made lots of carbon, had poor ring sealing, marginal oil quality and had inefficient air filters, the decrease in wear from efficient oil filters would be much more apparent.

Most of the studies done on wear vs oil contamination and filtration recently have been done on HD diesels... which still have more "oil dirtying" tendencies and live in a tougher environment. There is more of a correlation between filter efficiency and wear in that venue.

One study from Dave Cline at Parker Filtration that showed that when bypass filtration was added to an engine and the oil was compared to the same engine without it, (IIRC) the TBN retention of the engine with the bypass filtration was higher at 15K miles than the engine without filtration was at 5K miles. Dirty oil puts a greater load on the oil's additive package and depletes it sooner than oil that stays cleaner, so it able to last longer.

As an experiment, I'm running a bypass system on my F150 and while WM were tracking per 1K intervals with other analysis on the engine at 10K, TBN was still VERY high (on a conventional MC oil BTW) and the oil's ISO cleanliness code was actually better than the new oil (which was also tested). Oxidation and nitration levels were also very low. Will be resampling at 15K.

They are designed for extended drains and are generally more robust as the Euro manufacturers have a larger number of hard to obtain certs and approvals.
