How come all these alleged contaminants in fresh unfiltered oil are not showing up in VOAs?

Because they either don't exist, or if they do they aren't something of concern that can damage an engine. Can you imagine that bottled oil has to be poured into an engine, circulate through the oil filter to be safe to use in an engine. Imagine all those poor OPE engines that don't have a filter, they're doomed.

Because for the most part, people don't understand what a typical VOA spectrographic analysis shows and does not show, nor even a basic understanding of how it's obtained. And yet we get all these ironclad prognostications about future performance from them.

OMG you're right! Yesterday without thinking I poured 600 ml of 15w40 T5 into my 12 year old 190cc walk behind JD lawnmower
without filtering it through an old sock. Then, I mowed for an hour before noticing that the air filter had fallen off.

Be careful it could grenade next time you use it.

EXTRA 10, that's actually funny. One upsmanship. 20W-70 anyone?

Yes I was waiting for someone to go to an extreme to prove a point. It started on pg. 1 with 20w-50 in a Civic and grew from there. Its getting somewhat difficult to have a rational discussion without hyperbole.

I think what saved it this time is the stale dated 32:1 two stroke premix from last year I'm using up in the lawnmower.

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.

With regards to what you know about that particular engine are the test results relevant when compared to a mass produced engine engineered to run a 20 grade?

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?

Oh MY! I better prefill them 5 oz of oil or ... Watch out poor motor!

Flood mode? I've never prefilled any oil filter in my life.

My poor cousin in Sarasota is in Food Mode - 9" of rain in 5 hours last night!

That sucks. Those flood cars will be finding their way into the used car market is my bet.

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.

I was taught it doesn’t matter. And never losing an engine among various manufacturers (and oil brands) including modified engines supported that lesson. Also years of quick lube changes on fleet vehicles continued to reinforce my behavior. So I just kept on going. Why do something that doesn’t matter? That said, I’ll probably start doing it after this LSJR’s video. I think I have finally been compelled to pre fill now.

I got bitten by that once. Black Beauty used 1993 Lincoln mark Viii with the powerfull pre OBDii DOHC INTEC V8 for $19995. Back in 1996 only 20K miles.

Had window busted. Carpet musty. Dealer said radio taken. They fixed it. I bought it.

A few days later rear air suspension went flat on the highway. Brought it to a nearby lincoln dealer. Told me this is a flood car. Body computer was rusted.
They wouldn't honor warranty - showed me rust 1/2 way up the dash support braces and under the seats and on the springs.

Learned my lesson.

 

[buster]

Can someone tell me what point in the video they talk about prefill? I can't find it and don't feel like watching the entire video. TIA.

Never mind, I got it.

That sucks! I've been fortunate, the used cars I bought over the years I knew the history of. I do however know that flood cars often find their way to the Metro NY area pretty fast. I'm certain nothing has changed.

Stick around b/c I am about to learn how to pre-fill a cartridge filter that is in the vertical position on top of the engine. Very much looking forward to this. I guess I could install the filter on the housing, exposed w/no case, then pour oil all over like hot-fudge on a sundae, then put the cover on?

We still don't know how to? I'd like to keep my MB diesels from failing due to those huge vertical cartridge filters that know one understands how to pre-fill...

I glue the filters on with rtv.

Start @ ~28-30 min.

That's when they also talk about more water in the engine if you don't pre-fill with thin oil. But with thick oil and no pre-fill, no water!

I would like some expert explaining that. It's above my pay grade!

Maybe thicker oil provides a better film or blocks combustion byproducts better at startup till oil pressure gets there due to no pre-fill? Just a wild guess ... They all fall under insignificant category if that's the case.

 

[OilUzer]

Recently changed oil in my Tundra and it has a cartridge type oil filter and I can't pre-fill. Thinking about trading it now due to excess engine wear! And all that water in there using a thin M1 EP 10W-30.

EXTRA 10 was marked on the bottle of oil. That's what I thought was amusing. Loosen up a bit.
