think about this? oil filter care??

[digitaldrifter91]

ok this is not my idea. but today i went to my local auto parts store and the guy who worked there was selling oil filters to this one guy. the guy said which is a good oil filter, and the worker said "fram", the customer said "i heard fram isnt a good filter" the employee said "if you change your oil filter every 3-5k miles then you dont need a good oil filter, only for extended drains like 15k"

now what u guys think of that?? hehe im sticking with my bosch but i really had to share this. there are some people who think changing their filter everytime they change their oil is worthless...im still trying to convince my friend to do that. but dont you guys think the employee is a little 'over rated'?

The sales guy is full of crap--as are most parts store people I've dealt with.

Anyone who doesn't change the filter with each oil change deserves what he gets, IMO.

Well...the kid in the auto dept of Walmart told me that you should always use the recommended size filter and an Over-size one was not a good idea.

Well, after 10 years of oil analysis and multiple brands of filters (and having cut opne a few too many) I have come to the conclusion that filters are for catastrophic failures. That is, they trap large particles only but I have yet to see a filter cut open that under normal driving (no RX, no flushes etc) is full of dirt or contaminants. So, yes, if you change your oil every 3000 miles it doesn't make a hill of beans what kind of filter you use. Fram or whatever.

I agree with the clerk in this instance!

I can see someone using a Fram in ignorance, but to purposely use a piece of junk on a machine they've paid $20,000 - $50,000 (or more) for is just plain stupid, I don't care if they change the oil every other day.

Why use a Fram when you can get a better filter for the same price or even cheaper? Plus Frams cause valvetrain noise at startup in a lot of cars-that will damage your car.

haha i wanted to throw this site in that guys face hahah let him read about it...man i was about to bring in everything i learned about oil filters....but i am lazy....

Well, Bob (our host) is currently using a Fram and claims better flow due to less restriction. I don't use a Fram. My point is that it really doesn't make any difference what you use if you change it every 3000 miles. And, engine damage from a filter decomposing is about non existent and it is the oil that does all the work in todays engines, the filter is simply catastrophic protection. I have simply come to that opinion on my own and it is only my opinion.

the guy you talked to was right. it's not economically feasable to grab the most expensive Super Duper Mega Oil Filter Tron 5000™ on the shelf. people use the cheapest oil and frams and get 200,000 km (or miles) out of their engines then junk or sell the car because they get bored of it. the same is likely to happen to mr. Joe Q. Synthetic. to me that's why synthetics aren't worth it.

 

[digitaldrifter91]

i dotn use synthetics...dont trust it. i dotn care what the specs are, i dont want ne leaks and stuff...i use regular oil with a bosch filter. i upgraded to bosch because i like the filter element compared to the frams cardboard...its about 6 bucks though...but i noticed it being much quieter when i start the car. it may be a little more restrictive to some people but only by a small margin. when i change my oil im going to open it and see what it caught..then ill do my moms van which is running a fram and see how that turned out...but really i think it should be changed every time

 

[MavRick]

I change my filter every time and was using Fram's since they were the most readily available until I started reading on this and other sites about how bad they are.

I now use K&N filters, but they are probably overkill for a 5,000 mile change. None of these filters filter out the 5-15 micron particles with good efficiency so it seems the only way to get really good filtering and flow is to have a two filter setup with one high efficient bypass and one that's high flow. Those that want to run 200,000++ miles should look at this kind of setup.

Al, over the years I have talked to the 'Filter Hotline' several times concerning the filters that we sell and use in our locations.
Concerning using an oversized filter, it was explained to me that just because a larger filter may fit properly doesn't necessarilly mean that it can be used safely for an alternate application. Specifically they always talk about the pressure rating of the by-pass function being different for different applications.
According to them, you can get unfiltered oil flow if the by-pass has a lower rating, and a serious restriction of oil flow if the by-pass rating is too high.
Does this seem right, or is it all just a bunch of marketing crap. Thanks, Kit.

 

[Patman]

With GM cars this isn't a worry, since the bypass is built into the block, so filters for those cars have no bypass valve in the oil filter anyways. I've always run longer filters on my GM cars.

It is true that you want to match pressure spces, most filter manuals will have this listed in the back.

Also it is not always necessary to match exactly. Remember a larger filter will have less of a change of restriction becuase the larger filter area will flow more oil thus cause less restriction.

I believe most moder US cars are 7-9 psid, some european cars are up in the 20 psid range to it is not always true.

Good luck in your search. If you can't find a larger filter you can always install a remotely mounted filter.

Some full flow filters are better than others and none of them are any good at cleaning oil. When you drain your dirty oil your full flow filter is still clean. The only thing that makes any sense is when the filter gets dirty instead of the oil. There are several filters on the market that clean oil. Some have elements that cost more than an oil change. Some are messy to change. All have oil lines going to them. Proper filtration and synthetic oil are for people that want the engine to not only last a long time but to also run as smooth and as economically as possible. It is true that many people spend too much money and effort on equipment they won't keep long enough to reap the benefits. These are the guys you hope owned the car before you bought it used.
I was looking at RV's once in CA. There was my dream camper on a used Mercedes cab and chassis with a Motor Guard M-100 oil filter bolted to it. It was too rich for my blood. I ended up with a new 1971 Datsun with a little slide in camper and porta potti.
