In a pinch, for something like a weed wacker or backpack blower or chain
saw, can automotive synthetic motor oil be used in place of two-stroke oil?
What's the difference between two-stroke oil and regular motor oil anyway?

Supposedly produce less soot and carbon to gunk up the combustion
chamber and exhaust port.

If you're going to run anything but 2-stroke oil I'd only do it in an emergency.
Check your owner's manual. My two stroke weed wacker said straight 30
weight no detergent motor oil was fine, but you'll want to check your
own model's manual.
Non-detergent 30W oil is hard to find.
I know of 3 places here that carry it ... and this is a small town of
4,000 population .
Technical differences you'll have to research, and good luck with that!
The oil companies are secretive!
SAE30 single standard MINERAL oil
SAE30 single standard MINERAL oil was always used before the market-ers
got at it in the 1980s (NOT MULTI SAE oils)!
Thats what I always use in
any twostroke that doesnt specify 2T synthetics, eg. more modern super
high performance motorcycle 2T engines.
The advice from long ago was to never use the multi grade nn-W-nn oils because of the synthetic gloop additives used to achieve the multigrade characteristics and the same applies to the synthetic 2T oils (which are usually thin and pump-metered to the engines from a separate tank) and
very pricey.
SAE30 mineral is still available - I have to get it by the 5L. C+

I agree with Charlie+ because the oil manufacturers probably have bigger advertising budgets than their manufacturing budgets because in the end
it's all probably the same stuff.
But how would we know what makes oil coming out of the ground into
something labeled as "the best two stroke oil in the world" on the bottle?
SAE30 single standard MINERAL oil
Is SAE30 no detergent oil the same as "mineral oil"?
I thought mineral oil (like the stuff at the pharmacy) is different?

I also thought that up until recently people mixed regular non-detergent single weight oils into the gasoline at a 30/40/50:1 ratio and it worked.

What are "2T synthetics?" Answering my own question is Mr. W: https://en.wikipedia.org/wiki/Two-stroke_oil
2T just means "two stroke" but maybe not as the first sentence was so confusing that I started wondering if I knew what a two-stroke engine is! "Unlike a four-stroke engine, whose crankcase is closed except for its ventilation system, a two-stroke engine uses the crankcase as part of the induction tract"
Huh?
What is that sentence saying?
I always thought a two stroke was all about the number of strokes, and not about using the "crankcase as part of the induction tract" (whatever that means).

I agree they must put some kind of "gloop additive" to get that spread between cold and hot viscosity which probably isn't good for the engine (whether it's a 2-stroke or a 4-stroke engine) when it heat carbonizes.
The advertisers only tell you the good stuff but they never tell you the
bad stuff where there must be "more gloop additive" to make the spread
wider and that means more bad carbonization at the same time.

I've seen clear mineral oil sold in the pharmacy for drinking as a
laxative. Is that the same stuff?

I think the question is one of emergency as not everyone lives within 25 miles of a store that sells motor oil. I certainly don't.
Looking it up, this says that you can (but not everything on the Internet

It says the motor oil pollutes a bit more than 2-stroke oil might, and it recommends the heavier 10W40 over the lighter 10W30 high temp viscosity but it says there may be more carbon buildup as a result of the four stroke oil additives (the larger viscosity spread has more additives to make it so).
It also says vegetable oil works as long as the engine stays warm most of
the time as it "solidifies when it gets cold" (luckily you usually use it
all up in one sitting and you can empty out the little left if any).
It says homemade 2-stroke oil can be ethanol and grease but it doesn't say the concentration so that's not all that much helpful.
It says not to use transmission fluid though as it's not a lubricant.
It says the purpose of the oil is to [a] mix with the gas, and [b]
lubricate the piston, and [c] burn off cleanly.

The difference is the residue left after that oil burns and the
additive package . Modern 2 strokes are finely tuned high performance machines and they need the specific additives in the right base oil .
Cheap out on the oil and you're going to be buying a new unit .
Echo brand owner's manuals and product literature say their 2 stroke
power equipment (leaf blowers, chain saws, etc.) need oil that meets ISO-L-EGD, JASO FD specs.
Curious how few of the 2 cycle oil brands list what specs are met on
their packaging/containers whereas most automotive motor oils do.

Bring on the castor oil...

Paraffins that won't burn cleanly. So you'll cloud the neighborhood with stinky smoke and have to clean the cylinder afterward. After you finish mowing the lawn you'll have to clean the windows too.

You're right, but way over the top added drama since the tiny bit of extra smoke doesn't matter as "dramatically" as you're trying to make it matter.
