What oil should I use in my 2-stroke?
The 2-stroke oil base can be castor, petroleum, semi-synthetic, or synthetic. Modern two-strokes use synthetic oil to avoid high emissions and oily formations on spark plugs. You mix the engine oil with petrol or gasoline at a volumetric fuel-to-oil ratio.
Do I need to put oil in a 2-stroke engine?
Unlike a four-stroke engine, a unique feature of a two-stroke engine is that they do not have an internal oil reservoir. Instead, two-stroke engines require the owner to mix oil into the fuel at a predetermined ratio in order to ensure the engine receives adequate lubrication during operation.
Can 2-stroke oil separate from gas?
The gasoline is simply boiled off leaving the 2-stroke oil as the residue in the crankcase. If the gas and oil do not mix, then the oil and gas would separate out into two phases in the container which should not happen.

What type of oil should I use for a 2 stroke engine?
If you’re looking to get 2-stroke oil for your engine, you should get one with the longest shelf life. There are four different types of 2-cycle oils out there, and the type you choose will determine the shelf life and level of viscosity you get. Before we go into the 2-stroke outboard oil with the longest shelf life, let’s take a look at the different oil types and what you expect to get: 1 Castor Oil: These oils give you high levels of viscosity and lubrication, primarily due to their plant-based source. 2 Mineral Oil: These oils, also known as petroleum oils, have super-high levels of viscosity. With that comes a high level of smoke, making them less popular in the market these days. 3 Synthetic Oil: This is the most common oil type in the market today, offering good levels of viscosity and low smoke emission. 4 Semi-Synthetic Oil: These oils are a mix of mineral oils and synthetic oils, giving you the qualities of both oil types.

Can you mix 2T oil with TCW3 oil?
Seems that some 2t oil is a bit "difficult" even when fresh. Some TCW3 outboard oils can't be mixed with other tcw3 oil without gelling for example... I have used some husqvarna oil for the weeder and chainsaw, the oil was ca 15 yrs old but unopened- No problems at all. Anther bottle of same oil, opened, showed some strange lumps floating around. Probably moisture ruining it. I suppose that many oils would be ok even if old if stored properly. The only thing I can think of is the additives deteriorating or dropping to the bottom of the bottle. The oil itself is not breaking down over time, ask the dinos... Look at the oil. If it looks like new, use it. Else... dump it.
What happens when oil is pumped around the engine?
The biggest issue in use now is contamination. As the oil circulates around the engine it picks up dirt such as soot and microscopic slivers of metal worn away from the moving parts. This is good in that it takes the dirt away from the engine but even with a good oil filter it can eventually become saturated with debris and start to form a sludge.
What About Oil Inside An Engine, What Happens There?
Everything that could happen to break down oil in a container, is even more likely in use inside an engine. It is subjected to much higher temperatures and, of course, mechanical action. As conventional oils in use start to break down straight away, the maximum recommended driving between oil changes used to be only a few thousand miles. Depending on whether you drive hard miles – characterised by lots of short trips where the engine oil barely warms up – or easy miles – such as longer highway journeys – your engine oil can last a full-service interval such as 18,000 miles.
What Do The Oil Companies Say?
There is a general consensus of terminology coming from the oil companies that unused, unopened and stored in its original container out of extremes of temperature, motor oil will last for an “extended period”. They then go on to suggest that the oil shouldn’t be used after a few years; the exact period varying between 2 years (according to Total) up to 5 years ( Mobil ).
Why Do We Need Motor Oil?
The primary purpose of motor oil is for lubrication. Inside the internal combustion engine, hard metal surfaces slide backwards and forwards across each other at high speed and at very high temperatures. The oil forms a fluid barrier between the moving parts, lowering friction and, crucially, reducing wear on major engine components like pistons, connecting rods, crankshaft and of course the cylinder linings of the block itself.
How Does Motor Oil Expire?
Extremes of temperature can affect oil in different ways. Too hot and thermal breakdown occurs reducing the oil’s viscosity (its “weight” or thickness), which if used leads to a decreased flow rate and in turn to increased oil consumption, the build-up of deposits and potential damage to engine surfaces. Too cold and sludge will form in the oil, blocking engine oil passages and eventually becoming too thick to flow at all.
Why is oil so thick?
Too cold and sludge will form in the oil, blocking engine oil passages and eventually becoming too thick to flow at all. Another possible degradation cause is oxidation, more likely with a container that’s been opened, which is where the oil molecules react with oxygen molecules in the air.
How to clean oil puddles?
If any oil is spilt it can be straightforward to clean up if you know what you’re doing. Pouring cat litter or sawdust over the split will help to absorb the puddle before it stains anything,
