Maybe its just me but has anyone else noticed that the 5 qt jugs seem to be underfilled lately? Over the past 6 months with 3 different oil changes on the same vehicles that have always used right at 4.5 qts to the fill mark after running and topping off are now taking the full 5 qt jug to be full. Next time I think I will mark the level of the jug and refill afterwards and double check, but this last time I was pushed for time and forgot about it. Maybe its just me....
