This is a very good 50:1 oil mix for my weed eater and the chain saw, Large enough for the price and easy to mix 50:1 for both weed eater and the chainsaw . Right on time as i did use some old mix then had to clean out the fuel tank, This new mix took care of that well, not as much smoke either now, Performance is good and does not smelll bad like the old mix was. thanks !

Great oil mix

Size: 2.6 fl. oz (Pack of 12), Number of Items: 12

Sure saves time and money by combining the two products and since it’s synthetic oil it takes kess to do the job and as a bonus my equipment never smokes and upon teardown of my old blower it is cleaner than ever before with less wear!

Stinky, but Made in USA

Size: 2.6 fl. oz (Pack of 12), Number of Items: 12

I bought this product because it was one of the few 40:1/50:1 synthetic 2 cycle oils on Amazon. I have machines that take both, so it's a nice thing to have just 1 gas mix. Anyway, I'd say this product works. My leaf blower hasn't seized up or anything after hours of use, but this oil is noticeably more stinky than the last random, generic product I bought at the farm store. It's a kind of harsh pollution kind of smell. It's hard to describe. It doesn't put out a cloud of smoke. It's just stinky. Not the smell of what I'm familiar with the old, non-synthetic 2-cycle oils of the past. Anyway, I thought you should know. I gave this review an extra star for Made in USA.
