I'm going to change my oil tonight and wonder what oil and filter you guys use on an 340 CAT engine? <BR> <BR>I'd look in the owners manual, but its in the boat 50 miles away. LOL <BR> <BR>Thanks

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.

Are you saying Walmart is going to do the oil change or are you buying products from them?

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. <BR> <BR>I wouldn't let Walmart touch a Kia much less my boat. LOL

Fram PH5 or TG5 should work. I also always use shell rotella t 15W-40 on all my oil changes.
