I usually do 6000 miles but after reading The last two recent threads about Motorcraft filters I decided to do an early change out. Filter came out of 18 Ford transit 350 with a 3.7 L. Van gets used for commercial refrigeration with 50% highway and 50% stop and go driving. Replace the FL500s with wix 57502 Havoline pro ds 0w20 👠( I know I know it calls for 5W 20 I grabbed the wrong one out of my stash my neighbor was Cleaning her yard and bending over if you know what I mean I totally forgot what oil to grab...) but then again i'm sure it doesn't matter 0w or 5w. Getting back to the filter filter look great what's your opinion guys and gals??
