Lake Speed jr. Thick vs. Thin video.

[Cujet]

The thing absolutely can’t stand about this guy is that whenever he has any sort of guest he either speaks over them, or makes movements and seems like he’s ready to speak over them. I find it distracting and quite honestly it gives me almost a sense of anxiousness where I can’t concentrate on what the other person is even saying because I’m waiting for him to interrupt.

That's typical of a fast thinker. Professional politicians and quality news personalities have back and forth discussions down to a science. For the rest of us, we are not quite as polished.

My filter is horizontal too and I fill it up all the time. let the filter absorb up the oil.

That is great news for you! I feel it's a waste of time. Especially if your only loading the filter element.

Haven't been pre-filling oil filters since 1967.

I agree. It's going to take me 20 years to do 200K miles at this point and I just don't see filling it vs not filling having a meaningful impact on the 10-12 years I may keep a vehicle.

You do whatever you want...

Good luck pre filling the new cartridge filters......such a stupid idea.

Isn't the intent of cartridge filters easier recycling? IIRC that came out of European guidelines 25 years ago.

 

[RazorsEdge]

Or the horizontally mounted filters like on my vehicles.

Yup exactly!

I get that prefilled filters are a good idea,but I'm not dumping oil all over the place just because "it's the thing to do"

 

[nascarnation]

Does any manufacturer actually recommend or require prefilling oil filters in their service manuals? I've never seen it.

I need a transcript of this video, just to be sure.

click "more" in the yt description and then "show transcript" button

I posted a synopsis of the video and for some reason it was removed. It's a 40 minute video, I listened to the entire thing while coding. However, I wouldn't have the patience to sit through the entire thing without doing something else.

And the reason for the deletion is given above.

 

[The Lube Guy]

And the reason for the deletion is given above.

Got it, not a problem. I was just trying to be helpful.

They go over a lot of stuff, and the wear talk starts around the 30 minutes time.

This thread start has been merged into the existing thread. Other threads about this video have been removed. One thread on this topic/video, please.

well the silly thing about pre fill of oil filters begs to ask one vital question: If pre fill is so important then why do so many vehicle manufacturers design and sell to the public vehicles that one can only install the filters vertically undeneath with no way on earth to fill a filter anyway?

Absolutely Kohler is written in the manual must pre fill

With today's variable output oil pumps, flow volume is a matter of software and very likely, a pressure sensor, although even that's not "for sure". When the farthest cam bearing in an OHC/DOHC engine is starved for oil, it is likely due to no-flow conditions at that bearing cap. Despite normal flow rates through the pump.

Ultra low viscosity oils can, in some situations, be responsible for shorter engine life. I'm simply bringing up one way this can happen. Things are fine, right up until they are not.

I've mentioned oil lubricated chains many times. Manufacturers now use coated pins and parts to extend chain life with ultra low viscosity oils. As we might expect, this improves chain life markedly. Unfortunately, the coating has a lifespan too and once used up, chain "stretch" is rapid.

Yep … Those pumps are ECM logic all day long … My GM sense throttle demand and up the flow right as RPM’s start to increase - But, the Jeep is even more strange - it will kick into high stage even coming off a mid throttle - I think it’s when the 850RE downshifts …

At least they knew how to mount mine …

At first I thought you were talking about my ex wife.

I own a crosstrek with upside down filter I still pre fill.

Prefill is kind of redundant if you do the foot to the floor crank for a few seconds before starting it up.

Basically…. LSJ needs Lorazepam…

So you can’t just say it beats it in every way. LSJ even mentions in the video that the usage of a particular engine will determine what you should choose. There is no one size fits all with oil.

These graphs (from King Bearing, who are journal bearing experts) show that as the journal bearing clearance increases, a thinner oil does worse than a thicker oil in terms of MOFT. It also shows that no matter what the bearing clearance is, more viscosity always results in more MOFT. So using a thicker oil in tighter bearings isn't dangerous, but running too thin oil in looser bearings could be since the MOFT could get very low, causing more wear. So yes, as mentioned before, if a more modern engine like in an everyday modern car was used, the difference in the wear metals seen in the UOAs may be less of a difference than seen in this engine.
