I didn't get a chance to use this filter until almost two months after I bought it (thanks to unscheduled surgery). It just sat on my workbench in the original box. Due to exceeding 30 days, I don't have a return option worth considering. Only now did I notice a very significant dent in the bottom of the filter. There is no way I am going to take a chance and put this questionable filter on my new engine.So, I will chalk this purchase up to experience and toss the damaged oil filter into the trash. Anyway, I found the same filter at Walmart for less money and I was able to inspect it before buying it.I buy lots of things through Amazon without any problems. Apparently these filters get some rough handling somewhere along the way. I have three cars I maintain myself but I won't be buying any more oil filters through Amazon. Live and learn. Buyer beware!
