Default Using Amzoil in an older 2-cycle
In article 9ee985c9-359f-4fe1-84d2-
, says...

I know that the ancient engines recommended using a quart of 30 weight
engine oil to gallons of gas, which was primitive, then with 2-cycle
oils the recommended mix ratio went from 24 to 50 to one, Now the
synthetics are going up to 100:1 ratios and for a modern 2 cycle I
think that's OK, but I'm not sure about the designs of the 70's.

My brother is an Amzoil dealer and he things it's the greatest thing
since malted milk, and I like synthetic 2 cycle oil, but I'm wondering
about the recommended mix ratio. personally I think 100:1 is a bit
thin.

Anyone have any thoughts?

The oils I use for the two stroke bikes are synthetic (once you start
you should not go back). They are designed for 50:1 but I run 32:1
anyway as do many of the racers we ride with. Until you are looking for
that extra couple percent performance at the very top end of your
machines limits, I am told it can't hurt, only help the engine last
longer. BTW, we (and our pro friends) use exclusively Amsoil
"Dominator" two cycle oil in our machines. With naturally aspirated
engines, you should not have much problem with the mixture. We do tend
to pump a bit of blue smoke on startup, but once the engine is up to
temp it's not as bad... Hey, at least the plastic on the bike is green
