LSjr Video "Facts About Oil Changes"

[fantastic]

Titled: The FACTS About Oil Changes (What The Owner's Manual DIDN'T Tell You)​

Anyways, He says he's going to keep his oil filter on through multiple oil changes b/c it gets "better as they get older". He claims it's from what he learned about air filters at Donaldson. What does the crowd say about this or other details on the video?

These claims are somewhat surprising considering Donaldson claims air filters are using, essentially, static electricity to gain efficiency but oil filters?

He is not changing the filter for his 500 mile and 1500 mile oil changes, on a brand new vehicle.

It's not like he's leaving it for 2 normal OCIs.

I Understand that, he'll be fine, but listen to what he's claiming about "performance". I will point out that these x2 shorter mileage intervals can be just as demanding, if not more, than if the engine was broken in for an oil filter.

Not how oil filters work….as they load they become less efficient. ISO testing shows this.

Don’t see the vid.

I'll go back and listen more carefully. My post was just trying to provide more context to the folks who were likely to comment without watching the video.

What I found interesting is that he felt the need to flush the oil in the bottom of the pan, with a fresh quart of oil, after draining the old stuff ... but was willing to leave the filter (with old oil).

Did he heat the new quart up in the microwave first? If not its just going to mostly pool in the sump.

Truly, SMH.

As far as running a filter for 2 OCI - I don't see a particular problem with a quality filter. I doubt its better. Some of the bigger openings may get clogged, but it also may end up in bypass longer so its likely a wash at absolute best.

In theory, particles having gone into the filter would have been captured by the media. Based on previous videos, he's recommended this one-quart "flush" when switching between oil types to help get the previously used oil out of the bottom of the drain pan. Since he's sticking with the OEM oil, he probably is using it to help get sediment from the pan. I question its effectiveness, but it's his quart to flush.

I did my first OCI at 500 miles, then took a long trip, so it was ~4k miles on second OCI. Last OCI was 5.6k miles and odometer had just hit 10k. The filter was changed each time.

A large number just do 5k OCI twice on 20k filters …

That makes even less sense since the "dry" oil spec - ie on new/rebuild is usually 1+ quart more than the oil change spec and hence that old 1 quart is still in all the passages that can't drain and will be on every oil change. He is simply wasting a quart and propagating bad information.

This guy clearly knows very little about how engines actually are made or work.

Then again, when he says "Oil is in my blood", he's stating facts, not speculation. (I've never heard him actually say this)

I found the vid. Most of it is solid advice. But oil filters DO NOT become more efficient as they load like air filters. That said two short oci’s in this case will be fine.

I really don't want to go back and watch the Donaldson video again, but in LSJR's latest video, the short clip he played was the guy saying "air filters". To a point, it may apply to oil filters, but once passed its maximum filtration, it goes into bypass. See video below.

Yeah and the smile on his face...

Zee explains it well here.

This is exactly how the "hokey stick" efficiency curve starts out. As the delta-p increases, already captured particles in the media start sloughing off and going down steam which the particle counter sees as worse efficiency. I've posted about this many times, but nobody seems to believe it, lol.

I like Lake, but he's definitely wrong here about the oil filters. They do not get better with use, they get worse due to the pressure gradient. Air filters get better with use because the pressure differential is very low, density is very low, and the static of particle accumulation helps capture other contaminants. With an oil filter, the oil is much more dense and under a lot more pressure, and thus moves the media aside to force its way through, reducing efficiency. The more clogged the filter, the less available media for the oil to go through, and thus the greater the pressure differential and lower the efficiency. (until it becomes completely clogged)

EDIT: As I dive into the topic more, I'm finding more conflicting information. Some studies show it increases with use while some other show it decreases. I think, in either case, the use of a high efficiency filter from the get go won't serve you wrong regardless of how it does with use.

This has been rehashed here for a decade. Since it's your $$$$ do what you want with quality products and call it a day..

Apologies, I should've stated that I purposely didn't upload the video as I thought it wasn't going to pass the crowd. Also, those that want a whole story line regarding the video I wasn't going to do regarding this information. Again, I should've said I did not post the video though. Thanks!

I was thinking the same!
