if you have remote oil filters that are inverted, make certain the filter you buy (no matter what brand) has an anti drain back valve or you get a second or two of dry run every time you fire it up.

I have used many different brands over the year including the poor Fram which has an undeserved bad reputation from long ago. Never an issue.

I would not say that Fram's reputation was undeserved! When I saw the teardowns of the various filters, I was HORRIFIED to see the cardboard failures inside the Frams, as that it what I had been using for years. I have not used them since and have not seen any other teardowns to see if they've made improvements or not.

hi guys, I work in the Middle East and we can't always buy the top brands. I work with a lot of Cat engines and Perkins Like C-15 and C-18 and 3406 but we always change oil and filters at 300 hours. If we can we will use top brand oils and filters but many times we use Fram, Napa, Wix and a Turkish brand Sampiyon. I never had a problem with these lower rated brands. But like I said, we change them every time after 300 hours max.
