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.
Salad dressing Salad dressing that's sold unrefrigerated will last unopened for 12 to 18 months. After opening, it will still be good for six to nine months, as long as it's been continuously refrigerated. And salad dressings sold in the refrigerated section will be good for six months, or until the date on the bottle, as long as they're stored in the fridge at home. And as for that leftover pizza or Chinese takeout? Both are safe to eat after three to four days in the fridge, but toss 'em if they make it to day five.. . . . . . .
