This was my second service with Zippity and have had 2 problems. The first was a significantly overtightened oil drain plug. I needed to use a breaker bar to remove the plug on a follow up oil change. We were very lucky to know have a damaged oil pan. On the latest service I have a oil thumb print on my A pillar with inches of the zippity oil change sticker. I must say this survey would be much worse if not for a great customer service follw up by Nico. He shceduled a interior detail and insured the oil stain was removed. In the end though I unsure if i will use the Zippity service again much less recommend to people I care about.
