My motor requires 6 quarts of oil an my dilemma is that the 5 quart jug will be on sale but that extra quart never is so I pay full price for it an there goes my savings. I could by two 5 quart jugs an store the other jug that has 4 quarts left but I don’t like to do that since I’ve unsealed the jug. Just wondering if anyone has come up with a 1 quart container that seals really well to store unused oil from a 5 quart jug
