You run straight gasoline and Sta-Bil for alcohol free gasoline.

That’s what she had.  But I guess 4yrs is too long even for that.

Well , the facts are the facts. Today's gasoline has the shelf life of a gallon of milk.  

 You need to go and see why 6 emergency generators throughout the county would not start/run . Problem #1 a vendor put bio-diesel in all of them. Not his fault , it was during a "go green" phase of life. Problem #2 and the people "in charge" didn't think it was important to program them to start/run on a weekly basis to verify operation. I spent 40 man hours to find all this out . 

 Lessons learned  . Never use bio-diesel unless you are burning a dozer pile. People will tell you just enough to mislead/ make that just enough for you to make poor decisions . 

I am leaving out the bad part of the story because it smokes me too much to tell .
