Where is the "demarpaint camp" ?

Google maps could NOT find it.

Its been mentioned in a few posts just can't find it.


The 'demarpaint camp' location is highly classified for bitog security reasons. So it can't be found on any map including Google.

Very little is known beyond that, except that those in 'dermarpaint camp,' prefer to change their oil filter with each oil change. HTH

Yes it is highly classified, secure, and highly fortified.

FTR- I like cartridge oil filters a lot, especially now since I've had the opportunity to service a few. If one were so inclined to run a filter for two OCI, unscrewing the cap, letting the oil drain from the filter housing, and inspecting the filter for tears and defects would be quite easy. The fear of leaving close to a quart of dirty oil behind, or a torn filter would be a thing of the past. You'd have a seasoned filter which collected some dirt, which is said to be more efficient, win win possibly. This could be a have your cake and eat it too moment for some.

Until I started reading posts on BITOG, the notion of running an oil filter for more than one oil change never crossed my mind. It still does not compute. Filters are not that expensive.

You guys are so funny.

It never crossed my mind either until I came across a cartridge filter, unscrewed the cap and watched the oil empty from the housing. It was at that point in time I had the revelation that some of my concerns were addressed. But I'll still changing my filter with my oil. Fear not.

It all depends on what filter you use, and what condition your engine is in. Plenty of guys run a filter 2 times and even 3 times as long as it's not over the rated mileage of the oil filter.

Example ... only went 12K instead of the rated 15K.

With a cartridge I would want to change the gaskets if I removed the filter to drain it. They seem to be sold with new cartridges only. In any case waiting for two years and two intervals to cut a canister filter open is too long to wait. Consider the $4-10 spent on a new filter an entertainment expense.

I thought they hid Bush and left Cheney for bait.

ZeeOSix - that is a good looking filter. Picture perfect after 12K miles.

On one of your posts you showed a flow rate vs DP chart. IIRC of the Fram filters the TG was most restrictive, the Extra Guard was next and the Ultra Synthetic was least restrictive.
Given the '04 Ford 4.0L V6 was not back speced for 5W20 presumably because the oil pump needs a higher visc oil to maintain oil pressure at high RPMs. Wouldn't this make the Extra Guard and the Ultra better choices for 5K mile OCI with 5W30 conventional oils for this application?

Don't know what chart you are referring too ... there has never been a Delta-P vs Flow chart published for the Ultra, but it is very good flowing per Motorking (he did give some numbers in a thread).

The delta-p the filter creates will be about a 1/15th factor of what the engine oil pressure will be. In other words, when the engine oil pressure shows 80 PSI (at high RPM), the delta-p across a typical oil filter will be around 5 PSI. If the engine oil pressure was 30 PSI at idle, then the delta-p across the oil filter will be around 2 PSI.

With a positive displacement oil pump in good condition, the delta-p across many different oil filters would likely only be +/- 2 PSI when the engine oil pressure is at 80 PSI. In that case, there won't be any negative effect on the engine at all.
 
WellOiled - if you want to see some flow data for the Ultra, here's the thread where Motorking got some numbers.

Start reading from here: LINK
 
ZeeOSix - Thanks.

Flow Rate vs PSID chart

The chart is a few posts below.

For the Fram filters, Ultra is the most free flowing, followed by the Extra Guard and Tough Guard is dead last.

Does anyone know what the '04 Ford Ranger 4.0L V6 oil flow rate is vs RPM?

Where does that chart say Fram Ulta? That chart is old and you make a big assumption that it relates at all to filters sold today.
 
Nate1979 - you are right the legend shows Ultraguard. And all this time I thought it was the Fram Ultra line.

I am not sure what an ultraguard is.

The day after any data is published, a product change can occur.

I do 7.5K OCI on my Escort (with semi-synthetic) and will probably switch to a Fram Ultra and only change the filter every other time. Currently I do change the filter every time.

The chart you see with Ultraguard is referring to the AC Delco product which is a synthetic media filter.

The Fram synthetic filter is just called Fram Ultra, which used to be called Fram Xtended guard

Is there a chart showing pressure drop with filters run at new, and at their full load capacity? I believe the multi pass efficiency test stops when the pressure drop reaches a certain value. Which means, or implies, flow is restricted by dirt, to say it in simple terms.

If there is I haven't come across it
