First time user, registered just to ask this question. My 2005 Mazda 3 2.3L sedan is leaking from the oil pan. I'm looking around for an oil pan and want to know is it normal for some to cost $200, and others up to almost 2K? They even look different. I'm assuming going with the cheaper / smaller one isn't the best idea? The shop quoted me for a SPECTRA PREMIUM MZP15A at almost 900. I'd rather spend $2-3 on the smaller one, if it'll work. I'll post a pic, any advice is helpful. Thanks in advance.
