What are you mixing? I have been using Ams oil in every thing but my push mowers and log splitter. I reason I use dino in them is very low hours of use a year and I am too cheap for Ams oil. When I use Ams oil I don't mix anything. The only time I mix something is I mix oil and gas in my 2 cycle chain saw and that is a 50:1 mix. I am always looking for a way to save money, so what is the big secret to cheaper Ams oil? The big reason I use it because because I don't have to change my oil as often, so it dosen't cost any more in the long run. 20,000 miles car, 10,000 miles motorcycle, 100 hrs. on equment with hour meters does this sound right?
