Larger oil filter for better FE?

[suspectnumber961]

I'm using a Pure One PL30001 filter on a 1.5L Toyota engine. Also trying Mobil 1 0W30 synth oil. Expect to run this a full year...with maybe a filter change midyear. Will probably add 3 qts oil over the year?

I consider this a cheap to use and install bypass filter.

The filter on the left is the regular NAPA filter for the car...the one in the middle is the Pure One version for the car...the one on the right is the PL30001 "Mustang" filter.

While this is probably a fine oil change strategy, it is not a bypass system.

Bear in mind that you will probably never plug that filter, even over the entire life of your engine without filter changes.

How many miles are you driving per year? 3 quarts seems like a lot to me, any leaks?

Also be sure that your filter has the proper valving (drain back, bypass, etc)

If you want a true picture of your engine/ oil send off a sample to a lab.

trask 768 how about some part numbers on those filters, i might like to try one as i also drive an echo.

...whenever possible, I've always tried to use the "...largest size..." oil filter available, often one labeled as being for a truck.

...the bigger size usually means less backpressure resistance, longer life, bigger filter area, and slightly longer oil life.

Not technically a bypass filter...but a cost effective way to get closer to one.

The By-pass Oil Filter. The Ultimate Oil Filter.

"A regular oil filter will filter out dirt and contamination particles to about 20 microns in size. The AMSOIL Ea nanofiber oil filter will filter out dirt and contaminants down to about 5 microns in size. If you add the AMSOIL By-Pass filter system to your vehicle, it can filter down dirt and contaminants to 1/10 of a micron. You will get tighter clearances, better engine performance, and much longer engine life!"

My car uses around 1 qt per 5K miles...so over 12K it will use at least 2-3 qts espec if I change the filter one time.


Amsoil EAO vs PureONE - Topic Powered by Social Strata

" I've searched the forums and it seems that people choose the Amsoil filter over PureONE on 'faith' that the Amsoil brand is somehow better than every other brand.

After checking the specs for the Amsoil EAO filter and the Purolator PureONE filter I found something shocking... PureONE is actually better by the numbers.

According this this website: AMSOIL - AMSOIL Ea Oil Filter (EaO)

"Amsoil tested their EAO with the industry standard ISO 4548-12 and found that the 15 micron efficiency to be 98.7%

PureONE's ISO 4548-12 for 5 micron is 50%, 10 micron is 92.8%, 15 micron is 99.2%, and 20 micron is 99.9%. [info source: e-mail response from the tech/engineer department].

I've e-mailed Amsoil about the 5/10/20 micron ratings that isn't listed on the website but it would seem that PureONE is better than Amsoil by the 15 micron comparison.

So... PureONE's filter is not recommended for 25,000 miles oil change but Amsoil's EAO is by what logic? I guess if you trap more particles you have to change out the filter more often which means that the Amsoil one is probably letting more things through so it doesn't clog up and go into by-pass valve mode."

It's possible that the Amsoil filter has more filter media to hold the crap before it reduces flow too much. The Pureone's are very good filters, of course, especially when you consider the price. I can get one for my Jeep for $6.50.

I run 10K per change on my metros with a ph3600 filter (typically found on ford 3.0 V6) Its the largest filter that fits with A/C on the engine. It increases the oil capacity by 1/2 qt. which makes me feel better knowing that there's an extra 1/2 qt in there if it ever gets low More dilution for the filth from the engine plus larger surface area and capacity. Its all good

That's not correct. X quarts stock system capacity + 1/2 quart added filter capacity balanced against X quarts + 1/2 quart added to fill the filter equals the same oil level in the sump. Getting low is thus the same condition -- you do not have an extra 1/2 quart of margin.

[mcmancuso]

Sorry, not my intent. I don't care about level, I was thinking of total oil in the system. the metro only holds 3.5qt, and I feel a lot better knowing that if I'm a qt low there is still 3 in the system instead of only 2.5. A qt low is a much smaller percentage of 4 than 3.5. Its not margin, and I know that the extra 1/2 qt is in the filter not in the pan.

[comptiger5000]

The way to think about it isn't as safety margin, but as keeping the stuff more diluted. More oil volume allows longer time until change, due to slower additive depletion, etc.
