What is 2-stroke oil called?
Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines.
Is 2-stroke oil the same as 10W30?
“4-cycle” and “4-stroke” mean the same and “2-cycle” and “2-stroke” mean the same. “10W30” is the viscosity and is specified for 4-stroke engine oils. You don’t usually see viscosity specified for 2-stroke oils because you mix them with the gasoline (unless you have an oil injection 2-stroke).
What number is 2-stroke oil?
If do not know what it is, 40:1 is accepted as an standard ratio for two-stroke engines. This is 25mls of two stroke oil to 1L of petrol.
Is 2-stroke oil the same as mineral oil?
Yes. Traditionally, the most popular oil for 2-stroke engines, was an SAE 40 mineral oil. However modern 2-strokes require a low smoke, semi synthetic 2-stroke oil with a much lower viscosity, SAE 15. Older 2-strokes, do not appreciate these thinner oils, so Millers produce CM2T which is a mineral SAE 40.
Do I mix oil with 2-stroke?
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.
Widely used phrases
Villiers began to recommend 20:1 in the early 1950’s when self mixing two-stroke oil first became available. This is appropriate for both the engines you have . You will be told you can cut down the oil a lot if you use a modern synthetic oil. Do not do so. Synthetic oils are meant for modern two-strokes designed to modern standards.
What’s the best premix ratio for two stroke oil?
The following is extracted from the Villiers forum, and is applicable to most twostrokes built before the mid-1960s. As far as premix goes the 16:1 is still correct for running in a new engine and you can then cut down to 20:1 thereafter. Villiers began to recommend 20:1 in the early 1950’s when self mixing two-stroke oil first became available.
Why does pre mix two stroke oil get Smoky?
If a pre-mix two-stroke is smoky all the time its the riders fault not the bike. It is not being ridden far enough or long enough to keep clean. For years I rode two-strokes to work and they would get smoky in all the stop/start traffic.
What kind of engine does a two stroke motorcycle have?
The high-revving air-cooled engine is fed by two MicuniZC carbs and produces 50 hp (37.3 kW) at 10,500 rpm, more than enough to makethis lightweight racebike a real cracker on a race track. The newsthat Bimota was designing a two-stroke 500 cc road legal motorcycleto take on the superbikes was initially met with great enthusiasm in Italy.

Is the Rotary a two stroke or four stroke engine?
Regardless of configuration, all rotaries are four stroke engines. A common fallacy about rotaries is that they are two-stroke, like today’s chainsaw engines. That misconception probably arises because of confusion over how they are lubricated.
