I've used it a lot in the past too with no issues. Started using it when sunfish I think it was started talking about it. Used it for a year I guess but then started using Castrol super 2 stroke because of availability. I can only get the deal on Lucas in the closest city but I've been stocking up when I go to be sure I don't run out. Just gonna run the Lucas from now on as that's what's cheapest for me. Even the sonic co-op gas station stuff is more expensive then the Lucas.
Just a little info on Lucas oil. Forrest Lucas is a local guy here. He lives in the old but renovated bowling alley most of the time. He saved the local golf course from default and supports the community very well. He heads an organization called save the harvest, trying to protect farmers from radical leftest. I bought a horse from him back in the seventies when he was poor. I have used his oil when it was donated to a charity and my wife won the bid.

Nothing you have posted is factual or relevant to a two stroke motor.

ive produced the facts taken from an internationally recognised engineering combustion textbook, you haven't backed up your claim with anything but the usual nothingness, if you have got something that disproves the basic principle of quantity of oil, burning of oil = carbon = abrasive wear, let's see it then.

I won't play your games. Anyone half way on the ball will recognize the lubricants used in two cycles and four cycles are different as is the method of lubrication.
That this is lost on you is telling.

So you actually have nothing factual to base your claim on then, this is a good game, where you show us you have nothing but empty claims again.

I am claiming what you posted was not written about two cycle motors. That's factual. What's not factual is the dots you connected,period.

It is also about 2 cycle engines, but that is irrelevant, just show us something that disputes the quantity of oil burnt on the cylinder walls in relation to not causing wear from the abrasive carbon particles, surely you can come up with something other than your usual evasive dodging of such a simple question.

No its really not. What your are trying to do is take something about a diesel engine that may or may not be true anymore and apply to a two cycle *** motor. Apples and oranges.

Unless you can come up with something better than your own opinion with no facts, it will have to be taken that you have no proof of what you say, you are missing the fact that when hydrocarbons such as oil are burnt they produce abrasive carbon particles, two stroke, 4 stroke , petrol of diesel, the more oil the more abrasion happens on the bore walls, you fellows running excessively rich oil mixes are in really causing more bore wear, I'd go to say that it would extend to piston & rings also.
Produce some proof that says otherwise.

I'd like to read of some proof of your assumption.

You haven't provided anytging or merit that needs disproving. What you have done is provide a snippet from an old, outdated book that's talking about something totaly different than the subject at hand. By your own admission your not that sharp, bit this is rediculous.

No you wouldn't. ;) Even if these mooks had an iota of google fu, and basic high school level organic chem, they ain't gonna be able to digest the info.

Simple version, the "ash" left behind on burnup is what is abrasive, more oil, more ash, etc. Only thing is, this has been a KNOWN QUANTITY since forever, and various kludges have been made, since essentially the 1980s. ;P Some ash is not a problem, it gets kicked out with the exhaust, and isn't there long enough to be an issue. More ash/carbon buildup, might be an issue. If your saw looks like it's belching diesel exhaust, you got too damned much oil. And there will be enough crap accumulation to be a problem. lol!

Ok, here's the big ugly for those who like pain.

DI(detergent) additives (improves your mixology of fuel/oil/varnish/water/crap i.e. Seafoam/injector cleaner)

http://www.hazelpetrochem.com/pdf-file/Additives/multipurpose-engine-oil.pdf

Basic Bright Stock(made from paraffin residues in oil)
ash can be high, medium, low depending on refinement

http://base.shamrockoils.com/group-i-oil/bright-stock/basic-type

Synthetics of oh so many kinds.

http://www.soltexinc.com/pdf/Prod_Lub_Markets.pdf

PIB, grades and ash vary(generally "good enough" for most 2 cyc purposes)

https://www.lubrizol.com/ViscosityModifiers/Technologies/PIB.html

Someone bragging up their synthetic, with an overview of older tech.
http://www.3cyl.com/mraxl/oil-2T/2-cycle_lubes.pdf

and the general overview.

http://www.sea-doo.net/the-late-great-oil-debate/2015/04/

and some test results with views of cyls, etc after burning for a while.
http://www.3cyl.com/mraxl/oil-2T/ultralight.htm

And, one not listed, because it's an artifact of the past.

Asphaltic stock derived lubricants, while there was some experimentation in the past (50s-70s), it was so bad, it never got anywhere.
https://books.google.com/books?id=yd405jfKVOAC&pg=PA20&lpg=PA20
But... What did happen was the improvement of de-asphalting, cracking and reforming of paraffin stocks, etc.(what they called the bottom fractions)
http://www.machinerylubrication.com/Read/28960/mineral-oil-refining

So when you read the term asphalt today, it means considerably different things than it did in the 50s-60s. Interestingly, with super heavy crude, shale oil, tar sands, produces an asphalt too heavy for typical uses, and they need to figure out how to downmix it.

http://engineeredadditives.com/asphaltchallenge.html
Which means, you've even got improvements being done to "dead end" refined products.
