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.
Cooked ground beef should not be left unrefrigerated for more than  2 hours. Less time is better.   --------------   I was asking this question because my grandparentâ¦s and parents used  to keep covered cooked beef roasts on the counter until it was used  up so it didn't have that hard fat for sandwiches.
