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.

Get the larger one if you use more than a gallon a year.
Size: Single of 2.6 fl. oz, Number of Items: 1
Exactly as ordered. Price point is fine for mixing in 1 gallon of gas. I only use 1 gallon of this mix every year in my weed wackers.
