What would happen if you added 2 stroke oil instead of 4 stroke oil in a 4 stroke engine?

The biggest difference is this: 2 stoke oil is designed to be burned in the combustion chamber, 4 stroke is not to be burned and is to be in a crancase, so 2 stroke oil is designed to not leave deposits on anything in the combustion chamber when burned. (deposits on spark plugs, valves (or reeds) etc. 4 stoke when burned will leave a blackish deposit that is hard to remove on all these parts, so much so that it is recommended that you change the plugs if you fog an engine with 4 cycle oil by mistake. In very severe cases with prolonged use, it can leave so many deposits that it will cause the engine to keep quasi running when it is shut off. The deposits have to be removed by injecting water into the cylinders when the engine is running. This can be done with a garden hose regulated and 2 people when the engine is running (one to control the throttle and make sure the water doesn't stall the engine), and will immaculately clean the combustion area. (any rebuild mechanic will tell you that it is so easy to tell if there has been a crack or head gasket leak as that cylinder will be immaculate where the water has been present) Doubt if you need to do that/ as again, that damage is only from very prolonged use.

Would a normal petrol engine be damaged if you added 2 stroke pertol instead?
no, all that will happen is you might have a little extra exhaust while engine burns off oil that is in 2 stroke mix
Does your lawn mower require 2 cycle engine oil?
If it is a 2-stroke engine, 2-cycle engine oil is added to the gasoline. If the engine is 4-stroke, regular 30W motor oil is used. To tell if your engine is 2-stroke or 4-stroke, look for a spout where oil is poured into the engine. If there is no spout, then the engine is 2-stroke and 2-cycle oil must be added to the gasoline.
Is the 6.0 Briggs and Stratton engine a four-stroke or two-stroke?
The best way to know if an engine is 2-stroke or 4-stroke, is to look for an oil spout. If the engine has an oil spout where oil has to be poured into, it is a 4-stroke. If the engine has no oil spout and the oil has to be added to the fuel, then it is a 2-stroke.
Where do you put the oil in a lawnmower?
That would depend on whether the engine is a 2-stroke or a 4-stroke. You can determine by looking for an oil filler spout or filler cap on the engine. If it has one, the engine is a 4-stroke and the oil is added through there. If it doesn't have one, the engine is a 2-stroke and 2-cycle oil must be added to the fuel in the recommended ratio.
Can you use 2 stroke fuel on a 4 stroke engine?
Two stroke fuel uses the same gasoline but has had oil added to lubricate the internal engine parts of a 2 stroke engine which does not have oil in a sump to lubricate the engine like a 4 stroke. If you put this mix into a 4 stroke engine it will make a great deal of smoke and foul the spark plug, causing the engine to stop running. No permanent damage but definitely not recommended.
What is the difference between a 2 stroke and a 4 stroke lawn mower engine?
Four-stroke engines have a spout where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
Is 4 stroke fuel normal petrol?
4 stroke fuel is straight petrol, it does not have oil in it! If you use it in a 2 stroke engine you will seize the motor. 2 stroke fuel has oil added to it.
Do you add oil to the gas of your Sears snowblower?
That would depend on whether the engine is 2-stroke or 4-stroke (aka 2-cycle & 4-cycle). If the engine does not have an oil filler tube, it is a 2-stroke and oil must be added to the fuel. If it has an oil filler tube, it is a 4-stroke and oil is added through the filler tube.
What if I added 4 stroke seadoo oil in a 2 stroke 2001 rxdi seadoo if I have not started it yet should I siphon it out and add 2 stroke?
yes siphon it out 4 stroke oil is not designed to burn in a 2 stroke engine major engine damage is very likely
Is your lawn mower 2 cycle or 4 cycle?
Look at the engine on your lawn mower. If the engine has an oil filler tube or a "hole" with a cap on it where oil is added to the engine, it is a 4-cycle (4-stroke) engine. If there is no oil filler tube or place to add oil to the engine, then it is a 2-cycle (2-stroke) engine and the oil has to be added to the fuel.
How do you tell if a lawn mower is a gas only or a gas oil engine?
A gas only engine has a spout where oil is added to the engine. If there is no spout, then it is a gas/oil engine. FYI - gas only engine is a four-stroke (four-cycle) engine and the gas/oil engine is two-stroke (two-cycle).
Distinguish 2 stroke from 4 stroke lawn mowers?
Four-stroke lawn mowers have a tube where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
