Lake Speed jr. Thick vs. Thin video.

One of the more worthless things that's often posted on here, not merely due to their use of imaginary oil grades.

Lots of marketing by Driven in that chart. Marketing to a specific segment in fact.

Take yourself out of the mindset of a BITOGer. Twice just last week, I had to correct someone who thought the first number of a multi-grade was the actual grade. Both of them swore up and down that an SAE 30 was more viscous than a 20W-50 and thought the "W" stood for weight. The sad part, one of them is an ASE certified mechanic. The chart forces them to look at the 2nd number and not blindly follow the first. Those oil grades are commercially available as such, regardless of J300.

That chart is made with a lot of dumbing down which to us, makes it look kinda silly. It's also not a cut and clear guide, merely a starting point for someone who doesn't know where to look with a new build. Different engines of different bearing widths, crank stability, rpm, and load (plus other factors) will change that.
 
On 20 weight oils, we noticed that the ONLY make which wasn't consistently "burning" or otherwise consuming 20 weights was ford.

Maybe I'm just lucky, but my 2008 Civic (95K miles) has never burned oil. None. Even with up to 9,000k miles OCI. After the factory oil fill, I have only used Mobil 1 FS and sometimes Mobil 1 EP, always the spec 5W-20.

My 2005 Toyota Sienna (145K miles) likewise has never burned oil, or if it ever did, it was no more than a quarter of a quart in an OCI, which at times has been stretched in the 9k range or even more. I bought it new and after the factory fill I've only used Mobil 1 or Pennzoil Platinum. It uses 5W-30.
 
At startup low viscosity oil had the wear and heavy oil didn't right after an oil change.
I believe there's a huge difference between increased wear particle counts and actual wear out modes causing the vehicle engine to be rebuilt or scrapped.
I also believe less than .1 percent of cars/light trucks are getting filter pre-fills.
 
EXTRA 10, that's actually funny. One upsmanship. 20W-70 anyone?
It’s fairdinkum ain’t it mate?

Do I understand this correctly?

Not pre-filling the filter and using a thinner oil, results in more water in the crankcase plus much more engine wear and with thicker oil it's all good without a pre-fill? And a few UOA revealed all this? And the wear is significant or alarming?

What happened to uoa trends? Not to mention majority of the world and oil change places don't pre-fill. I think pre-fill is a bitog thing. I don't recall doing it prior to joining bitog. lol

imho, bunch of conclusions from potentially inaccurate or insignificant results i.e. nonsense in this video! 👈 :ROFLMAO:

Also I was recently reading something on this site against oil filter pre-fill. I may have to search for it. Something about pressure build up, etc. Maybe z can answer. Sounds like a no-win scenario. :alien:

Yep. The more I think about it, the more I think LSjr has "jumped the shark". For example viewers have asked about main and rod bearing clearances and no response. He has really done a disservice to the community by potentially using an extreme example to gain the desired result.

The video will now become "proof" from the group who says that you're wearing out your engine if you don't prefill your filter.

As for the "No prefill" comment someone said CAT advised to never prefill their filters due to potential containments in the oil

I have been pre filling my oil filters ever since I started doing my own oil changes in 1986. I am pretty sure that my dad taught me to do that. I don’t know why people seem to be against it. I can’t see how it would be a problem and logic dictates that it should help.
People aren't against it. People are against the idea that your engine will experience an early demise if you don't do it. I used to prefill as well.

That makes no sense. If there are dangerous contaminants in that new oil that you are putting in the filter, then what about the fact that you are pouring that same oil right into your crankcase?

The only thing it is likely to score there is the pump, since most all cars go from pan, to pump, to filter, out the the engine.

The 'no pre-fillers' are concerned that there are particles that will bypass the filter altogether.
 
Someone asked earlier if pre-fill was recommended or required by any auto manufacturers or in the service procedures?
If yes, over the years I've seen many violations by different dealers.

I do pre-fill but now am worried about dirty or unfiltered oil getting into my engine. lol

if you pour the oil directly in the filter, you are bypassing the filter media I assume .. Valid argument by CAT but how likely or unlikely is it to have contaminants in oil?
You would think it must be more likely than not if they recommend against pre-fill. No?
 
Can't prefill if the filter sits on top of the engine vertically. Where are all the damaged cars from the non-pre-fillers?

I'd say to anyone with that concern change brands of oil. If the fresh oil from a jug needs to be filtered before pouring it into the sump there's a problem with the company bottling that oil. JMO

Specs like bearing clearance aren't at liberty of being revealed on a public forum. I'm just familiar with that particular engine. This video was a response to a video by Engine Masters released last year where the same 2 oils were used in a worn out, low rpm marine engine with thick, high tension rings. This engine is a polar opposite of that to look at the effect on the extremes. There's more testing to come and far more ideas than funding will allow.
