I run a stihl farm boss and have a 1/2 gallon of 6 month-old 93 octane mixed with the additive that stihl makes. Anyone see a problem with mixing it with a fresh 1/2 gallon + additive and running it in the saw?
mayhem said:I have only ever had one experience with questionable gas in any vehicle of piece of OPE, on a recent trip to PA I refilled my wife's Audi down there with 92 pump gas. Car ran noticably badly...rough idle, loss of power, stuff like that. Refilled it when we got home with my regular unbranded gas stations's 93 and it went back to normal.
I use 6 month old gas in my OPE all the time, never had an issue wtih it. I usually put a bit of Seafoam in the jug when I fill it, which may account for at least part of that good fortune.

It all depends on how/where you store the cans too. Mine stay in my nice cool dry garage. If you keep them in a shed that reaches 100+ in the summertime then nothing is going to keep. Seafoam, stabilizer, pixie dust, nothing is going to help that fuel. I rarely have a 5 gal can go more than 30 days and never over 60. That includes my 2-stroke elixir too.

I am a FRIM believer in sea foam additive. My neighbor turned me on to it several years ago. He wanted to get his run about boat started one spring after sitting for THREE years. So I got some ether, miscellaneous wrenches, screwdrives, ect ect figuring on having to basically disassemble the Carb to get the gum out. He said " I sea foamed the gas when I winterized it last". I thought yeah right Snake oil I said But ill be darned if that 305 didn't start right up with a good battery charge SOLD! I started using immediately. I put sea foam in all my gas cans toward the end of the year and have never had a problem in the spring. I personally believe in it.

Roger that I know Jay can answer this for sure but what compression ratio are most saws.
shmodaddy said:Oh yeah @ 11- 12 :1 with 87 octane on a 350 you would have connecting rods pushed through the pistons in no time. I think ill bump my octane up to be on safe side. It would be impossible to hear spark knock in saw
