it has to do with the additives, not the oil itself. synthetic and conventional oil burn just the same in the combustion chamber, but oil with lots of anti-wear and anti-corrosive additives should only be used in the gearbox or crankcase.
You can but friction wise it will be shit. Engine oil will degrade and break down when coming mixing with gasoline. Also, its going to produce a lot of ashes and soot. There is a reason modern engines often need LOW SAPS oil.
so it would work then if I used small engine or motorcycle oil without additives? or no, because those oils still have detergents?

I always heard the big concern was all the ash. Proper 2-smoke oil is formulated for less ash.
Who knows with the additives. If I were going to do it, I would buy basic b***h conventional dino juice, not shit like Royal Purple. I’m sure it would be cool in a pinch if you had to run one tank of it before you could get to Tractor Supply.
Not OP but the thread got me thinking what exactly do they have to add or take away from 2 stroke oil and what's the differences between the different oil types. Not all of us are chemists or petro engineers so I think it could be interesting, to me it's just numbers on a bottle. I will call OP a gay though if it makes you feel better.
OP, you are a gay
ive seen old manuals of 70s equipment telling you to use 1/50 two stroke mixture or if not available 1/25 Gas SAE30 mixture. but they don't recommend it since it leads to more carbon buildup.
>You really need to read how a 2 stroke works.
You first.
The oil is not meant as a cylinder lubricant, the fuel/oil mix is passed through the crankcase to lubricate the bearings first before entering the combustion chamber. Some oil is left on the cylinder walls due to incomplete combustion, but that is not its primary function.
>Unlike the fuel, 2 stroke oil does not burn during the combustion process. Instead, it is designed to withstand the high temperatures and pressures within the engine, providing lubrication to various moving parts, such as the piston rings, cylinder walls, and bearings. It also helps to dissipate heat and reduce friction, ensuring smoother operation and protecting the engine from premature wear and damage.
>Not the crank bearings.
Yes the crank bearings.
Without the oil they quickly overheat, seize, and destroy the engine.
Have you even run a 2-stroke, let alone rebuilt them?

Bullshit. The cylinder wall and piston seizes and scores... That is the absolute first symptom of lean mix or straight gas run through a 2 stroke engine.
You can make 2 stroke mix with any oil, but not any fuel. Fuel from gas stations contain ethanol and most lawn equipment 2 stroke engines were not designed to use fuel with ethanol in it. You can buy some "city boy fuel" (premixed oil and fuel) to avoid the ethanol israelite if your local stores don't stock gas without ethanol in it.
As far as I know you can run ethanol fuel in pre-mix. It will just go bad faster than non-ethanol fuel... Hell I'm not even sure if the fuel I get on the farm has ethanol in it or not. I just run out of the bulk tank and throw some 2 stroke oil in it in the can...
Wal-mart has supertech 2 stroke oil mix at a very reasonable price... Way cheaper than the Stihl stuff.

There's a reason 2 stroke oil has been specially formulated for 50+ years, all you're going to do is kill your equipment faster.

Doesn’t matter.
It will work better than nothing but it will smoke a shitload and probably gum up the engine at some point
God this is stupid
The state of this board
Oof

If there were some massive price gap I would say there might be some gimmick or something but they're basically identical
Terrible idea, please use the stupid questions thread next time.
Or you could've made the thread on PrepHole and watch people fight till bump limit.

I mean if I absolutely HAD to use my chainsaw and didn't have any 2-stroke oil I would rather use motor oil mixed gas than just straight gas
2 stroke oil creates ash that lubricates the cylinder walls.
Motor oil does not.
Choose wisely
2 stroke oil is made to not create ash when burned. Ash acts as an abrasive and would increase wear in the cylinder.
You really need to read how a 2 stroke works. It creates a ash that. like graphite, asks as a lubricant. This is not the ash spewing from a volcano.
No doesn't. It's specifically formulated to decrease ash. The oil itself is the lubricant. Ash is just carbon and fricks 2-strokes up.

What seizes when you don't run oil? Not the crank bearings.
No need to make shit up when you have manufacturer reference material to cite.

Bullshit. The cylinder wall and piston seizes and scores... That is the absolute first symptom of lean mix or straight gas run through a 2 stroke engine.
So please explain how a 4 stroke, that does not use premix gas, does not burn and explode when running due to no oil in the combustion chamber?
There is a film of oil on the cylinder walls due to the oiling rings on the piston and the oil in the crankcase doing their job properly.
^This which OP would also know in seconds with a search engine. Anons who ask extremely basic questions have no excuse.
just buy two stroke marine oil and mix your own two stroke gas
This is from a 70s Yamaha enduro manual
motor oil composition has also changed massively since the 70s

Shill elsewhere
