    well, figured theres gotta be a few people on here that might know about this. i have some oil thats been sitting for a while and was wondering how long the shelf life on motor oil is. have a full case, 4 gallons of valvoline diesel oil and a small case, 6 quarts for full synthetic valvoline. they have both been sitting for about a year and have no use for them. wanted to sell em as both of them werent cheap and im sure someone can use it but dont want to sell if it might have gone bad in that time. let me know your thoughts. thanx :drinkup:

    Well I've heard you should changed it if a car has been sitting and not started over a year. Didn't know if anything in it settles or breaks down after sitting for an extended period of time

    I'm quite sure as long as the containers are sealed,the oil would not have a shelf life.

    its rust from the car and condensation that settles into the oil, not the oil itself. your fine.

    I read somewhere that oil was good for about 5 years in an unopened container. Exactly what happens after the 5 years I don't know.

    yeah but its something like 12-24 months usually and i think longer for synthetic.

    Ive had quarts of synthetic unopened for years and is just fine.

    if its in clear bottles or you pour it out and it looks like its seperating and not the same consistency from start to finish pouring, probably too old

    but ive only seen this once in my life and ive changed a lot of oil!

    I have been told that the molocules in the regular oil start to break down after 3 months thats why you change your oil every 3 months or 5000 Km which ever comes first but I don't know how that applies to oil that has not been run at all in a motor. I know the hydrolic oil in our compresser starts to seperate after 6-7 months so it needs to be Changed. hope that helps.
