Amsoil have lost a lot of customers from their advertising for Saber. I don’t like the company, how they distribute products, their terrible and inaccurate testing and the cost of the oil out here, the only thing I like about Amsoil is how clean it burns and lack of smoke I get with Saber.
IMO and experience 40-50:1 is too much oil for most ope with Saber and I found it does leave spooge, but for saws 40:1 burns clean. Anything that tends to 4 stroke fairly frequently / light load applications (hedge trimmers, line trimmers etc) I’d happily run 65:1 in.
