But does it smell good? Can I use it for milling in my ported, piped saw at 100:1?

OK.... here's a tangent...
Anyone got a super crap saw they don't care about? Two more tests: diesel and gas mixed, just wonder if it would work. not sure on what ratio to try though. Second is, we know you can use canola oil for the bar, how about for the mix as well? I am thinking that just might work, well mixed, really shaken up. Sure seems like it should work.

It all burns up, and there's no residual lubrication. Sulfur would work, but the acidity would eventually eat holes in everything. http://www.machinerylubrication.com/Read/28548/sulfur-used-in-lubrication

Ported 372 tuned to 14.2k on 40:1 Lucas semi syn. Saw was rich at that as it tuned out to 15k with a light 4 stroke. Bottom end is soaking wet. Sadly, this saw snagged a ring on me this AM [emoji20]

judging by those pics i'm tempted to say 40:1 is excessive oil lol unless i need to tune the saw at 15k? i thought lucas left a saw all crispy dry? lmao
So somewhere on the site someone mentioned if you take a 2.6 oz mix bottle and fill it full that's enough oil for a gallon of gas at 40:1.
In reality that bottle holds well over 4 ounces which makes this false. I'll just stick to measuring like I areas did.

Four cycles and diesels. Outdated at that.
Big end bearing doesn't look too healthy from what I can see. Sorry but I'm not liking what I see in the pictures, but this is just my opinion.

The big end does appear to show some wear.
And I could make any saw ran at 100:1 on cheap dino oil look oily like that 0retty easily.

Are you referring to what looks like wear or hot spots on the LHS ?....If so, well spotted !
I see quite a bit of scuffing on the bearing. The discolored areas look like heat may have been an issue as well.
It's not a surprise the largest coolest surfaces are covered in oil, that's not what to look for. The look of the bearing tells me the oil film strength may have failed under stress. Obviously numerous other things can cause similar results.
I also don't care for all the discoloration, and what almost look like carbon buildup on the lobes.
Let's just say I'm not going to be running Lucas oil anytime soon.

i don't take bearing cage color to seriously. if the big end of the rod was blue or where the pin goes through the counterweights i'd be concerned. guess what i'm gonna do? by the way, that saw was only run a lucas for a couple tanks before the pics. husky XP since new.
I'd like to see you produce any of evidence that disproves the combustion engine engineering fundamental quoted, two stroke, four stroke, petrol, gas or diesel, however old it maybe, carbon is carbon.
Anything that happened the day before yesterday can be regarded as outdated, just not quite as much like 16:1, 25:1, 33:1 or such in working 2 stroke engines.

Boat oil Shane ,let any saw idle for a bit it will be wet like that inside ,let me see a pic after you mill a slab or buck some 30 inch rounds one after another for firewood .

One of my saws tunes out at 15800 and 4 strokes ,if it is where it is happy run it that way .judging by those pics i'm tempted to say 40:1 is excessive oil lol unless i need to tune the saw at 15k? i thought lucas left a saw all crispy dry? lmao

well i assure you that was ripping a board. that saw hung a ring yesterday so i pulled it and put a ported big bore kit i had on it. went to the bush and finished the deed. all i needed was 3 boards.
