This last week I've been using the gasoline I have in storage just to cycle it. It has been in storage for about 18 months (or six months). I cannot remember if it was this last fall I put it up or the fall prior. The storage was in an out building with zero insulation. It was stored in the typical red five gallon fuel containers. I purchased the ethanol free fuel and added Sta-bil fuel additive. I've just added the second container (now 10 gallons) through a 2004 pontiac 2300 engine, 150k+ miles. All is well and no problems. I just wanted to share with others who may be adding to their fuel storage or just starting.
