Re: All two-stroke oil are the same!!
Well, you can certainly debate whether there's any meaningful difference between the oils within a certain rating/category.<br /><br />But to me there's no question that there's a difference between oils for 2 stroke air cooled engines and those designed and certified for 2 stroke water cooled engines. As Jimmbo said, there's a huge temp difference. Also, there's a huge difference in how they're operated. The air cooled engines I run (hand implements) are short bursts (less than a minute), mostly full bore, otherwise idle, no "mid range cruising". My outboard is extended idling, extended mid-range cruising, occasional full bore for several minutes at a time. Not a lot of up and down like a chain saw - or even a dirt bike. I'm no expert but I've gotta believe the oil is designed significantly different for those two applications.<br /><br />I can't imagine why anyone would not at least use the correct oil rating - air cooled vs. water cooled. I can understand why there's debate between cheap generic oils and expensive name brands though.
