Using Same Filter for 2 OCIs or More - I Disagree

[KevGuy]

I have a 2008 Ford Edge SEL AWD.

The oil filter is located right next to the oil pan in an upright position (tapping plate facing upwards). For me, the use of an oil filter for more than one oil change is just a bad idea.

When I pull the drain plug and let the oil drain and then loosen the filter I get more old oil coming out the drain plug and pouring down around the sides of the oil filter. So, when I sum up this extra oil and the oil inside the filter the volume is pretty much 1 quart.

The vehicle oil capacity is close to 6 quarts. I do not like the idea of having 5 quarts of clean oil and 1 quart of dirty oil in the engine. To unscrew the oil filter and then put it back on once all oil is finished draining doesn't make sense as it's just as well to put a new filter on. Furthermore, sometimes I crush the filter a bit taking it off. Thus, it's a new filter each time (yes, sometimes it is an orange can).

That's my take on the issue.

Makes perfect sense to me for your situation as described.

 

[Kuato]

I'm in agreement. Especially since only Honda recommends using an oil filter for 2 OCIs.

Have you actually measured how much of the 6 qts drains out if the filter is left on, or this is just a guesstimate?

Even if it was 1 qt in 6, it all depends on what the oil is and how many miles were put on it as to if that will compromise the oil quality or not. Most people change oil when it's only half worn out anyway.

Bottom line is you can do whatever makes you sleep like a baby at night.

I think a few other car manufacturer's have had that same recommendation before.

I measured it using an ice cream container during my last oil change.

On most engines, there is no problem running a filter for 2 OCI's. I personally like the idea of avoiding a "dry start" and avoiding the mess that comes with changing the oil filter on our cars. Running an oil filter for more than 1 OCI should only be done if the engine is clean, and if the filter is of good quality.

Ol' BOF should be popping in soon with his mantra.

Most people are dumping synthetic early anyway so the oil left in the filter isn't completely shot it's just not brand new. This residual oil shouldn't impact the new oil much at all. Most filters don't hold near a quart.

I will agree that most filters are best changed at each oci, but Fram Ultras are dual layer synthetic media and are fully up to the task.

I probably wouldn't run anything cellulose based double intervals.

Have run a few cars on same filter for 2 oci

My caveat is that i rarely run the filter for more than the original oci

18k in the case of the Pathfinder and i run it for 2 most times.

Only ever use Nissan or similar quality filter, a Mann is going on this week and it looks identical to the Nissan one.

The Hengst one that is on there is a natty satin black and has done just over 10k.

Also ran the Clio and Jag filters for 2 oci.

Or rather i have done an intermediate oci on the Jag and left the Jag filter on there, it is an insert and i did take it off and suction out the old oil as it is well positioned on top of the engine, the Jag diesel engine is designed to have oil suctioned from the top and has a pipe for that purpose. You can drain from the sump but why bother when you can get 99% of the oil out by suction.

Just pre-fill the oil filter and there is essentially no dry start issues. That's also how I know how much oil is in the oil filter. My oil filter mounts vertical so I can fill it completely.

My buddies' Toyota tacoma truck, the oil filter goes on almost upside down (tapping plate pointed toward the ground) and all we get to do there is just wet the media of the filter before it is screwed on, otherwise there is oil pouring down over the engine.

Hello, I agree with the O.P. "Out with the old" seems the appropriate battle cry here.

Whilst 901Memphis' qualification of upper quality filters being up to the task of two tours of duty makes sense to me, I think changing a sealed can full of crinkly stuff, old oil and caught dirt is wise. It's also cheap insurance.

We've read a lot about torn media lately.
Does anyone here think it's only possible with one brand or manufacturer?

Some country subsidizes its beer industry and voila'...an exceptionally affordable imported beer appears on our shelves.

Some country subsidizes its recycling industry and voila'...a mini glut of exceptionally affordable filtering media shows up on the world market. Shortly thereafter it appears in oil filters on our shelves...only we can't see it. It's in a can! Your classic "blind item".

Don't think that can happen? Why not? Because you didn't think of it?
Any shoddy, sub-standard, dishonest garbage can appear in any market.

That ridiculous cheap City Star oil.....oh no, oil is sacred. The DOT is on it.
Cheap booze.....oh no, alcohol is sacred. The ATF is on it.
Cheap oil filters....oh no, oiling our industry is sacred. The DOT, ASE and ISO is on it.

Don't kid yourself. Kira

Agree with Kira, with the media tears of late and our worries about filtration, using a filter for two OCIs doesn't make sense, unless you are using a filter designed for 15000 miles.

I agree with you in that I rarely run a filter for more than one OCI.
Middle-tier filters are cheap enough to change at every drain.
The only reason that I can see to run an oil filer for two OCIs would be if it were located in a position that made it very hard to get at.
In that case, I'd probably use a higher tier filter and run it 2X.

That is where we trust the company we are buying from (ie, Purolator in this case) to VERIFY with engineering and testing that the materials and design is adequate to meet the specifications the filter is supposed to meet. It's classical engineering and product design & manufacturing.

Since Purolator is having this issue, then it's up to them to find the root cause, fix that problem and get their product up to quality standards again. Either that, or ruin their own reputation and lose out in customers and sales.

It's a self balancing system. It's their choice how they want the scales to tip.

It's been mentioned here on this board a number of times. Those that have more info can chime in.

You main problem seems to be old oil. What if you had a cartridge filter setup that allowed you to easily drain out all the old oil from the housing with a drain plug?

I think it was at least GM in the 70's. We'd have to pull up some old owners manuals.

 

[fdcg27]

GM did recommend using the oil filter for two OCIs after the first one.
I'm looking at an OM for the 1974 Cutlass.
Drains were recommended at 6K or four months in normal service using API SE oil.
The viscosity recommendations surprised me.
5W-20 and 5w30 were recommended for temperatures below 20F, with the caveat that 5W-20 should not be used for sustained high speed driving. 5w30 was recommended for all season use in Canada.
I'm not sure where you would have found a 5W-20 or 5w30 grade oil in 1974.
Even better, for temperatures above 20F, you could choose from 20W-20, 10w30, 10W-40, 20W-40 or 20W-50. SAE 30 oils were also allowed above 40F.
I had though that GM pretty well excluded anything thicker than 10w30 after some time in the mid 'sixties and I was apparently wrong.
It's almost as though Subaru lifted the temp/visc chart for our '09 Forester from a 'seventies GM OM.

There is no problem.

There is no "What if." It is what it is.
