Ok, here's the story: I was getting ready to blow clippings at lawn number 5 today. I grab the BR600 and head across the front. I get about as far away from the truck as I can get (it's a big lawn).....and........you guessed it.......ran out of gas. So I walk back to the truck, grab the gas container and fill it up. As I'm putting the container back, I couldn't help but notice.......it's the mower fuel. Not pre-mix. DANG IT! So, rather than finding a bottle of oil and figuring out how much to add to the already-poured fuel in the tank, I just grabbed my trusty CRAFTSMAN handheld blower and got the job done. I guess that's what back-up equipment is for. Just seemed really weird, since I never use it. Anyone else ever pour the wrong fuel? Did you go ahead and use the equipment, or find something else?
