Best oil & air filters?

No auto maker makes their own fluids, filters or wires. Buying brand name = price gouge.

I've gone with Amsoil for years because it won't gel until -70 F. That's great in cold climates so you don't need a block heater. It's getting pricy, but the pure synthetics available in stores are almost as bad, so it's a matter of how you feel about that.

I've never had a problem with Fram filters, but I'm running Purolator for the Prius and my motorcycle because they are one of the few companies that make the filter size(s) I need, and they have an excellent rating for performance.

On a side note, the coolant on my dad's Highlander from Toyota was insanely pricey. Worse yet was that the instructions said to remove drain holes in the engine block to get it all out before filling. Toyota's service techs wanted double to do that. Their normal practice was to just drain and fill because it was faster and cheaper. We ended up doing it ourselves via a standard flush and fill, but we had to detach a coolant hose to get everything out until clear water flowed. The lines were too big for the OTC Prestone T-connector for a garden hose.

 

While I've used Pure Ones and never had any problems I suspect most owners will get satisfactory service from Toyota filters and name brand full synthetic oil changed according to schedule.

 

I was using the Toyota oil bottled by Idemitsu for them, but I used it up and am switching to Mobil 1. For filters, I use the Toyota ones that I buy over the internet.

 

I do not know any tests on Toyota oil & air filters ...... I'm sure Toyota specs are high!!
Toyota does use paper air filters over oil dried air filters; maybe this site might help;

Air Filtration Test - Bob is the Oil Guy - Bob is the Oil Guy
Remember; Toyota must be doing something right, in making a GREAT Prius!!

 

Where is this so called, " independent web-site "???
Consumer Reports?

 

I have nothing against AMSOIL !! They are just trying to sell their products. When a company does their tests, their results can very; and results can be read in different ways.

When you started this thread; it sounds like your mind was all ready made up. If you want to use AMSOIL, use it; and give us some feed back, later.
Most of your feed back, was to stay with Toyota oil filter and air filter!!
Their are some old threads on air filters and cabin filters.

Maybe you need to do a poll?

 

Troy, I've struggled with the same question, and I'm also a BITOG member. No PureOne cartridge is offered for the Gen III Prius, the Purolator Application Guide states, "Not Available - Availability to be Announced." None of the other cartridges on the market I've looked at can match the PureOne's filtration level or be considered a "P1 equivalent." M1 and K&N are a step down in filtration, but not in their quality of construction. The TRD filters I've examined had poor quality control, with split media along the seams. Wix, Fram, and German filters like Knecht, Mahle, and Mann? They might or might not be better choices. I'm sorry I can't help more, but I haven't spent enough time researching it.

Cartridges do have the advantage of being cheaper to produce, less wasteful of resources, and easier to inspect (before, during, and after use). The disadvantage is the highly-limited selection of cartridges on the market that will fit your vehicle. Sigh, I miss my 2009 Civic Hybrid, which accepted the PureOne PL14610 canister filter - but not getting the lower mileage.

I'd be less concerned about replacing the Toyota air filter, which appears to be a far better filter than the oil filter.

 

There is another thing you need to think about? ... AMSOIL filters as small as 5 microns!! That sounds GREAT!!
QUESTION: How much oil is going through it?....,. 15%; 20% What % ??
If the oil is not flowing fast ; Guess what ? Your ICE gets HOT!!

" The SAE J1858 test provides both particle counting and gravimetric measurement to measure filter capacity and efficiency. Actual counts of contaminant particles by size are obtained every 10 minutes, both upstream (before the filter) and downstream (after the filter), for evaluation. From this data filtration ratio and efficiency for each contaminant particle size can be determined as well as dust capacity and pressure loss as a function of time. Typical numbers for paper element filters are 40% at 10 microns, 60% at 20 microns, 93% at 30 microns, and 97% at 40 microns. " Here is the web-site: Oil Filters Revealed - MiniMopar Resources
And guess what? It is from Mopar??

Area filter size also makes a difference ..... the larger the filter paper area , the more flow you will have.

This is to give you something to think about?
Maybe Toyota knows best?

 

I have always used fram filters with (0) issues.
But will stick with O E M till warranty is out !!

 

Yes; I know they have by-pass valves; I'm glad you know that to!!
I agree, there is not enough info on Toyota oil filters.
I think Denso makes Toyota oil filters, according to Toyota specs.... what ever they are?
Made in Thailand!!

If you find a filter , let us know, what kind of oil filter and why?

I'm all for a better oil filter, because I tow with my Prius; but I change my oil every 5,000 miles.

Man; You are really DOWN on Toyota!!

Well...the OE oil filter is the cartridge type not the 1 piece metal housing style, you can see clearly thru the pleads. I don't see any holes or tiny holes at least it hold up really well after 10k miles. I've tried K&N, PureOne and it works the same. I decide to go with OEM oil filter at least it's cheap and meet the factory standard.
