Revzilla always delivers the goods I haven't found a local dealer to purchase my oil, so when I saw that I could get it from Revzilla I was pleased. The delivery was super fast as it always seems to be from them. The package arrived in good condition and I was able to get my oil changed without waiting forever or paying two arms and three legs to get the delivery. Thanks again Revzilla for being so great to deal with. July 29, 2013
