This is why I always preferred to run a larger 3600 sized filter over a stock sized 4967 if it fits my engine. More media surface area is always good and also less differential pressure under the same flow conditions. The only downside to running a larger filter is that it needs to be...

Running a filter circuit in series to boost Beta ratings is nice but isn't there more downsides of doing this since the drawbacks would include more pressure drop. Most industrial literature I come across regarding bulk filtration usually have multiple filters setup in a parallel circuit to...

Outdated SDS 2021 revision does reveal having PEA. Page 6 of 8 https://archpdfs.lps.org/Chemicals/44K_Fuel_system_cleaner_power_enhancer.pdf

BG 44K is the real deal IMO, I have used other off the shelf fuel system cleaners out of the rest, 44K has given me, friends and my customers immediate results to tell me about it. I never posted a photo here, out of curiosity I did ran 3 cans of 44K, 1 can per full tank fill before changing...

Looking at the photo it appears the flat spring doesn't looked like its preloaded against the endcap to keep the valve face fully closed and sealed...

I find this very ironic since Fleetguard, along with Donaldson, operates and markets itself and their products mostly outside of the consumer automotive aftermarket. Your company may be an OEM for HD equipment filtration and for some automotive joint contract venture. The average joe, even the...

Thankfully I'm in good supply with those with the stash sitting in air sealed ammo cans. I'm likely not buying anything from them again after all in inventory is gone. Sad part is millions of customers are pretty much unaware of this except a few groups auto hobby enthusiast hanging around in...

What we're seeing is BOM cost reduction to the extreme, even a filtration engineer would understand and warn their managers loose geometric surface tolerance from high volume stamping would make a non perfect contact seal. Its just a fiber ring they need to add to it. Which would probably cost...

I think we're both in agreement that the problems lies in the Media Element assembly design and not the filtering media material itself sourcing from all recent discussions of the bad metal to metal contact leaf spring seal and bad stamping quality would throw off filtration performance targets...

I'm not familiarized with what are the common or suggest target ISO cleanliness code of engine oils. I did a quick search and found some sources. One from Donaldson, which of course they have a very strict target cleanliness. And another chart showing common ISO cleanliness code ranges for a...

I'm not a fan of the new Toyota / Lexus front grille design, just too much gaudy look to it. BMW on the other hand still sticks with that pig nose shaped front grille for whatever how long its been going which makes it easily to identify that its a BMW.

Looks like yours came out perfect. Stude. Really want to run this filter again someday on my 2011 yaris daily haha

I'm not so active these days to check the UOA section of the forums but I found it, thanks. With the ISO Cleanliness Code reading at 22/21/18 doesn't seem so impressive for a filter that is rated for 25K miles. WearCheck is noting the particle contamination numbers are at abnormal levels...

What was the ISO oil cleanliness code if you don't mind me asking? The GM filter one too as a reference would be a good baseline to know.

Microsoft Excel and Google sheets have replaced mine. I used to have a Sharp Scientific calculator when I was in school back then.

Denso FTF aftermarket filters are fine, I haven't seen a bad one yet when searching back long ago in the forums. Its just you may randomly get a bad batch of Thailand made Toyota branded Denso oil filters from the dealership that may have a crack at the glued ends that could cause permanent...

Older production versions of the Fram Ultra had the logo sticker placed on the canister which is visible in the OP photo, the date code was laser etched back during this period which makes them hard to spot on the can. I believe later before Fram Group got acquired by Trico, they made a minor...

They don't make em like they used to. I'm quite surprised how rust free that base plate is, specially for how old that filter is. Thanks for the photos. It is worth noting that the fiber seal fit to the leaf spring is actually a interference fit so no light will actually shine through it. I...

The OEM Tokyo Roki is good enough unless its too price sensitive. Usually made in Japan or Indonesia which I have posted a thread long ago showing they are indeed good quality for what you pay for. The aftermarket is its own ball game of choices you have to make for yourself. There isn't...

Lets not forget that condescending sentence before that. What on earth is this guy doing in a forum dedicated to motor oil to drop such a brain dead comment. "Also, rather than pointless filter decapitations"
