Bosch

[HangerHarley]

Do Bosch (Robert Bosch, Illinois) filters have a Silicone ADBV? I did not know Bosch and Purolator were related until today, however Bosch just -exudes- Quality (Box, Filter, Appearance, Feel) while Purolator is a Blue filter in White Box or "PureOne" loudly advertised.

Ill pay $8 for a Filter if its a good one. $5 STP seems to be a "use it if you have to" filter and i dont know much about where STP would be made and how good they are vs other names.

My mechanic keeps telling me "They are all the same filters."

The Bosch is smaller than the old filter i took off, but Threads match. So it will get filled faster. My mechanic says this happens all the time, and the smaller filter is "better" and wont affect Lubrication or Filtration.

I will buy a Hack Saw just so i can slice open my old Filter. I have heard it will tell me a lot about the engine, which feels very strong via the Butt Dyno and behaves, except for some Tick and Consumptiion. Oil is discussed at length, and 5W-50 is still possible.

That said, how do you rate Bosch?

Stores sell: Fram, Purlator, PureOne, Mobil (limited,) Bosch (bought one,) STP (different store,) Motorcraft. Switching from STP, hear they are low-end. It was Bigger too.

Sadly I can't rate Bosch very well due to the thin flimsy casing of the 3510 that I got for a small block 350. I put several dents with my carpal tunnel wrists trying to muscle a 3510 off. (I forgot my wrench). I used to like bosch, but the casing was so thin, it felt like a fram ocod.

I'm good with Purolator, Wix, Mobil 1.
STP's are made by champion labs, very good filter, would not be afraid to use it, but it would not be my first choice.

Unfortunately, I won't be using bosch again until the casings are that of the Wix and Purolator.

Bosch oil filters are excellent. They have very high efficiency, and excellent build quality. They do use Silicon (orange( ADBV. Silicon is orange, Nitrile Rubber is Black. The only real complaint I've seen about Purolator/Bosch filters is the cans are a bit thinner than some other brands. Generally, bigger filters are better, if only because it means you have higher oil capacity for the engine.

STP is a good filter for idealy 5k drains, if you plan on going over, i'd go with a bosch. The STP is made by Champ Labs, and are made here in US. Same makers of AcDelco, Supertech etc.

X2.

However the thin can complaint is not an indicator of the filters quality. I use Bosch filters and really like them.

Bosch Prem. and Pure One construction and efficiency are the same, difference is the can exterior. They are excellent quality, high efficiency with silicone adbv. Recently cut open a P1 after a 1 year OCI here. Also, here is a page from river_rats filter study comparing the two filters. You'll note the same results.

Now as for your mechanic saying a "smaller filter is better". If it's not at least the recommended OE size, I'd not agree with that statement. Not sure why the Bosch used is smaller, shouldn't be. Perhaps you have been using a slightly oversize filter app. If you post your car, year and engine we could check it. Some folks here prefer an oversize filter, but haven't seen anyone ask for a smaller app. And as for mech saying "all filters are the same", from the standpoint of construction/efficiency, not true.

Lastly, while the Purolator/Bosch are not noted for can thickness, you can use with confidence in PC application.

Not quite. The Bosch DP has a a blended synthetic media, it has a much higher dirt capacity than the PureONE does. What exactly it is offhand, I can't recall, but it's much higher than the P1.

.. He says it repeatedly...

.. That they "All come from the same place and some say one thing and some say another."

I just let it slide. He generaly gets it right. Sometimes, though.. I get that. Hes the one thats been workin on cars for more than 10 years. Not me. Still..

He is now a Certified NAPA Master Mechanic whose Price tripled ($65.74 an hour plus tax equals $70 an hour) with his own Shop, officially NAPA Branded, paying off the Business and busy as all heck, all day, its like a Magnet people come when they see the official NAPA guy that gets them in and out hella fast. :Lol:

And he now uses NAPA Gold Filters. As well as NAPA everything else, and orders from NAPA since he is a NAPA Technician now.

Im bringing him the Bosch, and the Oil. Since he believes it is all the same.

*btw, the "Smaller filter would be better" he was referring to how it wont hit anything around it like a larger filter of equal thread would. He also noted that id see about a half quart reduction in Oil Capacity. He mentioned the Lubrication and filtration would not be affected and the oversize filter app didnt really make much of a difference. However you may be correct, the STP may have been Oversize and Bosch may be OE Size.

So it will get filled up faster, with gunk. Ill change it myself mid-OCI once i see where it is, should be pretty easy ill have to look.

STP does not have Silicone ADBV, does it?

Ill have to Slice the STP open, just like the show "Sliced." Right down the middle, with Hacksaw, not Chain Saw. (If thats the way to check out the innards, to see the good stuff inside, for Clues.) Since "They are all the same"

Please re-read my post. Nowhere did it mention the Bosch DP, it specifically said the Bosch Premium. Nor did the OP mention the Bosch Distance Plus, which has a thicker can/base and a greater rated holding capacity, about double, though same rated efficiency. The price is also double (or more) the everyday Bosch Prem/Pure One, though the P1 is available at a reduced price with AAP coupons, at Kmart or Amazon. fyi, there is a cut open view thread here, comparing the Bosch DP to the P1, should find it with a search.

I would suspect if it was hitting something then it was not the OE size, which you likely purchased in the Bosch.

The Bosch DP that i used on my Camry that was included with AAP Syntec special weighed 2x more than the P1's that i normally use.

 

[river_rat]

They have pretty thick cans and media.
Otherwise they perform about like a PureOne...like the long life version...in a prettier color.
Expensive though.

Or, to complicate things, when I buy Bosch in Canada, it's all one kind (no DP) and imported from Germany. Oddly enough, the German varieties have fairly sturdy cans.

 

[tig1]

Bosch filters are in the top five for quality. Very good.

As far as I know, the Bosch numbering system still uses five digits for German, and four for Purolator built filters.
The Distance Plus numbers I've seen are the same as the Purolator built Bosch numbers with a D in front.

If I recall the numbers correctly, my VW takes a Bosch Premium 3422, a Bosch Distance Plus D3422, and a German Bosch 71530 (or something like that)--with the German one being a totally different design and media.

Yep. That's what I get here - all five digit numbers, and a sturdy can.

What's the differences with the media?

 

[river_rat]

The American versions filter out smaller junk.

Germans seem to use thicker oils and change their oil and filters every so many years, so the filters are mostly designed to flow for long, long life more than right-away dirt grabbing.

 

[Gary Allan]

That's sorta what I try and communicate. It's not necessarily the fine level of filtration that one should seek. It should be holding capacity. The smaller stuff can be an issue of too low a significance to bother with. Having the capacity to hold all the bigger particles without filter saturation rendering it useless may trump that.

Thanks for the info. I tend to use Bosch, Mann, or Mahle on the Audi. Oddly enough, I can get them cheaper from my source than I can get Wix from my other supplier. Wix for the Audi costs double what the German filters cost, while for my F-150, I get the Wix for around $5. Go figure.

 

[river_rat]

I feel that if you change oil and filters every 5,000-7,500...or maybe even 10K miles... you might as well use the finer filtration (within reason) to catch anything you can, ASAP.

If you are leaving it all alone for a long run, you will want that flow, as the filter will hold the dirt and become more efficient as the miles roll by. Then the average dirt catching of the whole oil and filter run should be pretty good.

The German OEM VW filter (Mann built) I have for the microbus says to change every 30,000 kilometers or two years.
The media, while not what I would call porous, does not seem to be quite as finely spun as, say, a Purolator Classic...let alone a PureONE.
But it will probably catch as much fine stuff eventually, before the sump is emptied, in a long filter run.

That's my considered estimate of the situation, anyway.

Fine choices for the teutonic blood of the machine, if you use them as intended.
