I have used PRI-G the 16 oz version for a vehicle I had in storage. The vehicle had winter gas in it. I live in BC Canada so that means the gas or fuel very had unstable components in it; 18 months later when I was ready start the vehicle the gas not degraded and the vehicle worked started with no problem.
Best Answer: >If the ranch has a preservative added, give it a shelf life of about 3 months unrefrigerated. Otherwise, if it has been out for more than 4-5 days, at room temp then toss it. You are right, we are spoiled alright, but we also live longer than a lot of people do in the world due to less food poisoning.
If left out unrefrigerated, pasta will spoil within 24 hours.  However, if left in the fridge, the pasta will typically still be  OK 7 days later.onfidence votes 36.2K. Like many other questions about food-spoilage, this depends on the ambeint temperature where the milk has been stored. In a warm place it will spoil in less than a day. in a cool place it might last for several days.
