Hi, just wanted to give a bit of a warning to everyone who considers this filter. I discovered an oil leak about 2000 miles after the oil change. Upon inspection it looks like the gasket diameter is too small - the gasket only partially touches the mounting surface. When comparing the Mazda filter to Fram, you can easily see how much smaller the diameter of Fram's gasket is. I usually use OEM filters, but I had two of these Frams that I got together with oil on sale. Interestingly, this same filter is also used on a 2001 Lexus ES 300, and when compared to the Toyota OEM filter, the gasket is too small as well. But I haven't yet looked at the Lexus' mounting surface to see if the gasket would cover it completely or not.
