Oil Filters ---- Again

I know PC is banned from this site, but it sure is an interesting read about his cherished OEM filter.

That's a great thread, Stewarc. I interpret the construction a little different than they do, however. I don't use the OEM filters, but personally I think they look pretty well constructed. The YZZA2 filter has a large amount of filter media surface area for the size of the can, and the V6 filter uses depth filtration to pull out particulates. Both methods will do a pretty good job of keeping good flow through the filter and minimizing the amount of time the filter spends in bypass.

DC, below is what I mean when I say the Bobistheoilguy site is owned,

 

administered and moderated by salespeople who's goal is to introduce and sell

expensive, off brand specialty automotive lubes, fluids and filters to the general

public. Anyone like me who repeatedly argues against the need for these types

of products and / or continually points out the features and benefits of OEM

lubes, fluids and filters will eventually be banned from the Bobistheoilguy site:

Would someone with knowledge of both please give an opinion.

Not trying to start a flame war, just trying to get opinions from users.

Thanks.

no drilling, because if there was any oil in japan the US would have invaded japan so as to gain control of it.

Shaun:

 

Please name one country that the U.S. "invaded" in order to control their oil. Just one.

OBTW: If you're planning to answer "Iraq," please have your facts right and provide three sources backing them up. You see, inconvenient as it may be to you knee-jerk America-haters, the United States hasn't taken a single drop of oil from Iraq that we haven't purchased and paid for at current OPEC market prices! Just thought you'd like to know!

If so, Then why don't we invade Canada? They are one of our largest sources of imported oil, and the border is undefended. Heck, the Alabama National Guard could probably pull it off

 

(To my humor challnged colleages - extreme sarcasm is present).

How long have we been drilling Mount Fuji for Genuine Toyota Motor Oil anyways?

For about as long as US Toyota's have been running on oem Toyota air.

I agree with Shaun. Imagine if Captain Picard, from the Starship Enterprise, beamed Iraq's entire oil reserves up to Mars. What would we do? Would we continue our occupation of Iraq or would we pull out immediately so no more American lives would be lost for nothing? We would pull out, of course and not risk any more lives. And if Captain Picard had beamed Iraq's oil to Mars 2 years ago, we would not have invaded Iraq to begin.

the US does not invade canada because they already have invaded here via Walmarts, GE, GM, Ford, Mcdonalds etc etc,,,,,

 

But I can see why they may invade Canada in the future....

because of the banning of handguns, because of the socialist healthcare system,

because of socialist labor rights, because of the extreme lack of disparity

between the rich and the poor .

The information on that site is hardly scientific. It's pictures, some observations, but mostly analysis of filter disign provided by some guy. Perhaps is he had a PHD in Mechanical Engineering degree and di his doctorial thesis in fluid dynamics and studied the flow propertires of medium viscosity liquids and relatively low speeds.

Remember, and oil pump is directly driven by the engine via a chain or gear. It provides positive pressure since the design of the pump uses lobves that seal against the outside housing as it rotates. Therefore improveing the flow on an oil filter merely reduces the amount of HP needed to drive the pump. I'd be suprised if the oil pump used more than 1/2 HP on a bad day.

Leaky bypass valves...hmmm... did this site test them when they were at 200F degrees and covered with oil??? I doubt it. Of course most of the designs leaked on a vacuum pump. They aren't designed to seal air leaks. An oil molecule is dramatically larger than air particles... over 100 times larger.

I'm sorry but "Bob the Oil Guy", needs to update his scientific methods and come up wiht some quanititative tests that apply to the actualy environment a filter is subjected to.

I agree with paul. so far a few hundred US troops have died so that iraq can have a puppet government that will be overthrown in 12 months time - don't think it was liberation. the US invaded a country that, in the war on terror, is an ally (iraq rejected al-quaeda's suggestion to start up terrorist camps), and had as many WMD chemicals as i do under my kitchen sink. yes the US may be getting oil from iraq now legit, but remember that iraq is an opec nation that can influence opec countries. having an enemy in a little club that determines if you get energy or not would make the west (esp. USA) a little paranoid, so what do you do? invade, conquer, puppet government, secure supply of oil.

since to carry out the 'liberation' of iraq would involve the killing of thousands of iraqi children and women, and a thousand or so of 'our' guys, and the illegal invasion and occupation of another country (by UN law) i'd say the onus is on those who support the war to suggest 3 real items of evidence that the invasion of iraq was a good thing. i do not want to hear about imaginary WMDs etc 'cos they don't exist. why should i prove, to others, that a tatic that would have saved the lives of many, is sound?

please direct the replies to the 'politics' thread i started up.

Jeff726, your wal-mart change will be just fine.

Ah, but we got the Mounties, EH?

 

 

Speaking of oil and such, why not ask Gerhard Schroeder and Jacques Chirac their thoughts.

good point. they were quite used to recieving (illegal) Iraqi oil vouchers from Saddam under the UN sanctions and 'oil for food'. You left out Vladimir Putin.

 

Back to the topic-

Non Toyota oil, non-Toyota filter, non-Toyota mechanic performing the task - overload, overload, danger will robinson, danger........

Ah, but we got the Mounties, EH?

And a fine bunch they are, too!

 

Likely they are much more polished than the Alabama National Guard.

Hey DCStewart, here are a couple posts that came in today on the ClubLexus forum about K&N air filters:

"I used K&N on my last car. Big mistake. The K&N let thru some much dirt,

it gradually wore out my engine. The throttle body needed to be cleaned

twice a year. PCV got clogged. Oil got really dirty at 1000 miles. Look

thru the filter with your own eyes, you'd find holes as big as ball

point pen tip. That's unacceptable. The oil doesn't catch all the dust

and dirt. I would never put it in any of my vehicles again."

increase the holes on a filter,and thus there is more airflow while

decreasing filtration rate."

It sounds like improper installation or other problems.

 

At present, I've got three VW Jettas in the yard. All have had K&N's since new and all are running very well with little maintenance other than oil changes, filter cleanings and timing belts. All have clean intake tracts and needed no cleaning.

91 turbodiesel- 580,000 km

95 1.9 turbodiesel- 480,000km

99 TDI - 430,000km

Not goin to fight with you PC. I got the experience here. I've also seen cars with stock air filters fail at less than 20,000 miles. Cars fail ... get over it.

BTW, PCV Valves do not clog because of aircleaners.
