Hi, I ran across this canned gasoline at my local Walmart that was available in both 2-stroke and 4-stroke. (I’ve included a pic, which also shows the price.) My question would be about the viability of using the 4-stroke as an emergency fuel for my car, keeping one in the trunk “for just in case”and a few in the shed for long-term storage. Although quite expensive, the octane is correct. I am amazed at the claimed shelf life of five years in the can and two years in the tank. I was under the impression the even with Sta-bil added, gasoline would only be usable for maybe two years. Are you familiar with this fuel? If so, do you know how it’s able to last so long and if it safe for a car?
It is my understanding that the life of gasoline is determined by how long the more volatile components, like butane, will stay absorbed by the heavier compounds. As they evaporate, the gas becomes unusable. Five years seems like a long time for storage to me, but I’m sure some of our readers will have more of an idea.
