Remember that all 2 stroke oil makers don't make their stuff the same .. so all generalizations will be wrong in some cases.
BUT... in general .. there will be 4 differences from burning genuine 2-stroke oil
1 Less carbon build up in the combustion chamber and exhaust .. they call it 'low-ash'.
2 (related to that) - less crud gumming up the rings over time.
3 Less visible smoke.
4 Less 'stink'
(now the last two .. are almost more items of 'style' .. and its possible some people would actually like those features ?)
BUT ... you should also understand that there is not THAT MUCH difference between 2 stroke oil and regular motor oil.
.. and you could always substitute in a pinch without worry.
(thats why the guy freaking about 2 stroke oil in this tranny is just being a jerk)
Many 2 stroke oil manufacturers also put in chemicals just to give the oil a nice odor ... and the smoke from those bikes has an exotic smell like incense.
I love the smell of some of them ... Klotz is one of the 'perfumey' ones.
*... mmmmm ... I love the smell of 2 stroke smoke in the morning... it reminds me of ........... victory ! .. *
Also ... many oil bottles and cans will use the incorrect terminology and call 2 stroke oil .. '2 cycle' oil ... that is very commonly used among the general public ... and its wrong.
it may be a technicality .. but its wrong.
Are there 2 cycles? .. or are there 2 strokes per cycle?
Are there 4 cycles? .. or are there 4 strokes per cycle?
(they print it wrong on the cans because the majority of the public say it wrong .. and they want the customer to feel comfortable about their purchase)
Billy Bob goes to stock boy and sez .. (cartoon hillbilly voice here >) ... "hey .. whats this '2 stroke' mean .. izzat the same as 2 cycle ?"
Bottom line to all oil products ?
People like to attribute all kinds of magical properties to the liquids they put in their motors.
So you will hear all kinds of claims made about them .. by the sellers and buyers.
Guess what ?... it just doesn't make that much difference what motor oil or 2 stroke you use.
I buy the cheap 2 stroke oil sold at Meijers under the Citgo brand name ... for about $1.70 a quart .. buy 5 quarts at a time and it lasts me a long time.
... and I don't do synthetic.
I also believe the same oil is sold under different labels .. its the same inside (in some cases).
The smaller 'specialty' 2 stroke brands definitely put different additives in .. so they are gonna be a little different .. and one might be better than another for hardcore racing engines making big HP.
