2015 Mazda 5 at 190,000 miles
Out Penz Plat 0w20 : In Kirkland 5w20. Microgard Select filter (prefilled).
Also sucked/filled the small power steering rez with Amsoil SS ATF.
Most things went like a textbook oil change. However, this time, for some reason, the filter was on hard. It took an eyebrow-raising amount of oomph to twist it off. The previous gasket was pre-wetted and the can only spun on until connect and then 1/4 to 1/2 beyond... basically as far as my oily hands can go before slipping grip. This time, I didn't go as far... maybe 1/4 to 1/3 beyond connect. Perhaps it was because the engine was still pretty hot from a drive.
