Walmart sells the same marine filters that my dealership uses. I think they are made by quicksilver. As well they sell rotella t 15W-40 which I use every time.
It was a bit of a joke. I meant that I was doing my own oil change and planned on hitting up wally world for the parts since I get off work after hours.
I wouldn't let Walmart touch a Kia much less my boat. LOL
