Are all 2 stroke oils the same?

[Fishhound]

[#000000]There are many quality brands of motor oil for 2 strokes - just as there are for autos.[/#000000]

[#000000]One thing that I do is to make sure that I use the same brand and type of oil for the tank I have filled. In other words, I don't mix two kinds of oil in the same tank. I also like to stick with the same gas in the same tank. Meaning, if there is some left over gas/oil mix in the tank, I try to refill the tank with the same stuff from the same manufacturers.[/#000000]

[#000000]Gas and oils from different manufactures may have basically the same specs, but they could easily have different properties or different ratios of component compounds. I don't know if it really makes much difference, but regardless, I try to maintain consistancy as I think it could have an effect on performance. [/#000000]

[#000000]However, I could be wrong. [/#000000]

[#000000]Maybe an chemist, engineer, or mechanic could weigh in and give us the real low down.[/#000000]
