I was wondering if two stroke oil is the same as two cycle oil?

But that does not mean all two stroke oils are equal.

Not Necessarily! There is 2 cycle oil for air cooled engines like lawn mowers, snow blowers, and then there is Marine engine 2 cycle oil.

For marine use you want TCW3 oil. And the higher end stuff is fully synthetic.

NO, NO, NO!! :eek::eek::eek: They are DIFFERENT!!

Two-stroke oil is different from regular motor oil. It is thin and specifically made to mix with gasoline in the gas tank of two-stroke engines. This is how the piston is lubricated in a two-stroke engine.

Two-cycle oil is regular motor oil that you put in the oil filler hole on an automobile engine.

The confusion a lot of people have comes from not understanding just what the words "stroke" and "cycle" mean when talking about internal combustion engines.

A "stroke" describes the linear, or up and down, action the piston makes within its cylinder. One stroke for the piston to move up and one stroke for the piston to move down. A "cycle" describes the circular action of the crankshaft. One complete revolution of the crankshaft equals one cycle.

For every cycle the crankshaft makes, the piston makes two strokes. A two-stroke engine is the same thing as a one-cycle engine and a four-stroke engine is the same thing as a two-cycle engine. So an engine can be either two-stroke or four-stroke, OR an engine can be either one-cycle or two-cycle.

MAKE SURE YOU HAVE THE RIGHT KIND OF OIL FOR YOUR ENGINE!

No disrespect intended Mech girl but for the general public on this forum we speak of two stroke and four stroke engines and just to keep things on the simple side any reference to a two stroke on this forum is correctly translated as two cycle. That's my opinion anyway. LOL, this is coming from a plumber who has never rebuilt an engine, but some day I might. I hope I haven't missed anything obvious. Best of luck. Rick.

I agree with MikDee. Air cooled 2 strokes run a lot hotter than liquid cooled 2 strokes.

You are technically correct, but since you are using terminology that 99% of the public and most mechanics will not understand or agree with, then you are wrong. Very, very few will even know what a 1-cycle is. Sorry, effective communication is part of it also. And this is also a 4 and a half year old thread that you felt compelled to reply to. Please check the dates before dragging up threads.

Is this added to fuel or crankcase? mao9ThajHdvCyujsmZZDJCA.jpg And this one? 542301.jpg

Re: Is two stroke oil the same as two cycle oil?

Why are y'all posting in a 5 year old thread? And since this can of worms has re-opened - Does this mean a 2 stroke is a 1 cycle and a 4 stroke is a 2 cycle? I think not. 2 cycle and 2 stroke are the same while a 4 stroke and 4 cycle are the same. And don't confuse cycle with revolution. 4 stroke/cycle oil is called motor or engine oil and while the other is called 2 stroke or 2 cycle oil

While technically that might be correct, I do think that most folks consider 2 stroke = 2 cycle and 4 stroke = 4 cycle.

Only one person posted a 5 yr thread, and that post opened up the can of worms. I wasn't confused, haven't added the wrong oil in over 50 years ... ;)

This is incorrect. It cancels any truth in Mech girl's post.

Wikipedia, the free encyclopedia

Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil or 2-stroke oil) is an engine oil intended for use in two-stroke engines.

I can't resist. It's just like a woman to start an argument over something that happened five years ago. With that said, welcome to iboats mechgirl
