Best i have used.
a year ago
Before i bought and used this my lawn mower would start
but immediately it would stop. I went down and
purchased the 8 oz bottle and used a small amount
approximately an ounce. Cranked it up and it immediately
stopped. After doing this 4 or 5 times it stayed running
until i gave it throttle then it stopped. I cranked it once
more, allowed it to run idle for about a minute. Then i
gave it full throttle. It took it all and kept running. I
engaged the blade and began to mow. Finally it got
too dark to mow so i parked it. Needless to say this
stuff works great. And it works fast.

Great product I highly recommend
3 years ago
This product was recommended for my Husqvarna backpack blower. My machine is 6 years old and generally runs very well. But this summer it seemed to chug and choke a little bit after heating up. After treating my gasoline mix with this product and running two tanks through my machine, it runs and starts as if it were new again. GREAT PRODUCT!!
