    Is there a difference between HD 30 and just 30 weight oil?:confused:

    Naa, I've seen the crappiest Citgo oil called Heavy Duty and it comes out of the bottle looking like used waste oil.

    In this case, "HD" does not stand for heavy duty, it means high detergent. :usflag:

    I forget exactly but isn't the HD something to do with the detergent properties in the oil? In other words, some oils clean more in the engine than others.
