Filter for Mobil 1 0w20 extended drain

[MikeySoft]

It's my understanding that Honda's filters to 30 microns, SuperTech filters to 20 microns, and Bosch filters to 15 microns. I don't know what Mobil 1 or K&H filters to.

I'm wondering what would be a good filter practice for a Mobil 1 0w20 oil using extended drain. By extended drain I mean a mileage interval close to the "Normal" service recommended by Honda. They recommend 10k miles for my 03 Accord 4 cylinder so I'm thinking like 9K miles.

My driving is mostly highway and I put over 550 miles a week.

A theory is that a filter may clog up causing the bypass value to open if it filters smaller partials over an extended interval.

Honda OEM Filter (not Fram made)?
Honda recommends every other oil change or 20k miles of "Normal" driving so it should have no problem with 9k miles but it only filters to 30 microns.

SuperTech Filter?
At less then $2.00 each I could change it mid way in the interval and I'll get 33% smaller partials size filtering then the Honda OEM. The SuperTech Filter will be the least expensive filter even if I change it twice. I think the 0w-20 oil I'll have to add by changing the filter is more expensive then the filter.

Will 20 microns clog the filter if I don't change in midway?

Bosch Filter?
Maybe the 15 microns is too small for an extended interval. If I change it twice, it will be about the same price as a Mobil 1 or K&H filter. 15 microns is only 25% better then the SuperTech but 50% better then the Honda OEM.

Mobil 1 or F&H Filter?
I think the price is a little high and are they that much better? Also will they clog up on an extended interval?

The Mobil 1 filters are what you want to use for extended oil changes .To do extended the oil change oil must be clean as possible. Read up on bypass filters or Amsoil website that explains fine filtration.

The Mobil 1 is said to filter down to 10 microns, and the very similar K&N down to 20. I wouldn't attempt to correlate micron ratings to longevity before clogging/bypassing. Such correlations might certainly exist, but without actual flow data on a given brand's media, you can't objectively compare them, so no sense worrying about hypotheticals. Mobil recommends their filter for extended service even though it's high filtration. Personally, I'd go with maximum filtration regardless of drain intervals, and NOT assume the "lesser" filter can go longer until/unless someone can verify that with data. Bypass systems certainly have advantages for extended service for those willing to invest in same. For any extended service full-flow filter, you might look for the following features:

-Larger media surface area to forstall clogging.
-Synthetic (such as Fleetguard StrataPore) or synthetic blended media since additional acids produced over time can supposedly harm paper media.
-Silicone (orange) anti-drainback valve, instead of less durable nitrile (black).
-Open end bypass since extended intervals may allow for more junk to accumulate in the closed end dome (for closed end bypass filters) before bypass eventually occurs. The Motorcraft and Wix filters typically feature open end bypass.
-Teflon-coated or other low-stick mating gaskets.
-Using grease, in lieu of oil, on the mating gasket (although filter manufacturers generally recommend against this due to the potential for leaks).

I used a Mobil 1 filter and Mobil 1 0w-20 in my Acura RSX and had great results with it. I also had great results with the 5w30 run before that with Mobil 1 filter. I typically sample at 7Kmi and change at 9Kmi.

H and A accessories has the Honda Filtech oversized filters for less than $5. That is what I would use.

i use the bosch premium filter with Mobil 1 0w20. However, I will not do extended drains until about 20,000 or 25k, so I'll stick with 5k drains for a bit(plus winters coming anyway, I always do a change midwinter when my interval comes up again).

I'm using Pure One with Mobil 1 5w30 on our 02 V6 Accord. Just posted some results and wasn't very excited about them. Cu, Al and Fe went up some from the Pennz. purebase 5w30, but the lead came down. But, I changed the oil and not the filter, so that Pure One filter had over 8K miles on it. Going to take another sample with new filter at about 4.5K If nothing improves, will try another filter and maybe go back to Pennz. Have read that the Pure One may be too restrictive, may just try the regular Purolator filter that I use on a '90 Cutlass with 173K on it. UOA on this engine was better than the Honda. Pure one pretty much meets all the criteria that TC posted.

I found the following buried is Mobil 1's FAQ.

quote:

---

"The Mobil 1 oil filter has a 15 micron absolute rating."

---

In a different FAQ.

quote:

---

"The Mobil 1 High Efficiency Oil Filter has a single-pass efficiency of 98 percent for 10- to 20-micron contaminants vs. an average of 85 percent for conventional filters."

---

In the next paragraph they say.

quote:

---

"The Mobil 1 High Efficiency Oil Filter has a multiple-pass efficiency of 96 percent vs. an average of 82 percent for conventional oil filters."

---

They explane multiply-pass efficiency being lower
by the following.

quote:

---

"Contaminants that are trapped on the first pass may be pushed through the medium as more liquid flows through the filter."

---

But then they say.

quote:

---

"In addition, as contaminants are trapped on the medium surface, they can block the path of additional contaminants, increasing the filter efficiency during subsequent passes."

---

It sounds like the last 2 quotes contradict each other.

For the single-pass test glass beads of a known size are used. The single-pass efficiency spec given by Mobil 1 is with 10-20um beads. In the multi-pass efficiency test standardized test dust is used. The test dust has some particles smaller than 10um.

Good information on the last couple posts. I think that it's a good plan to change filters at midway if you are going say much more than 6K miles (Atleast-thats what I do) I think that STP, Bosch, and ST are fine choices here. I personally use the K&N and I will go 6, 7, or 8 K with that one.
