I stopped using echo oil mix.
2 strokes i use stihl as stated in their label mixtures.
It just didn't sound right with the echo oil.
When you go synthetic you can never go back to conventional.
I build engines for a living.
Nissan Race engines.
I don't use synthetics in my race car.
I just change my oils constantly.
I have people bring me mowers and they have never changed the oil.
temps it's what affects oils.
If you know what temps your dealing with and find the correct viscosity then you don't have to worry about anything.
