How To: Oil Filter Inspection - With NO Special Tools 

Thanks for getting your hands dirty and showing us the guts of a used oil filter.Plenty of new oil filter videos around but first time i have seen this done with a well used one.Certainly looks like the fleetguard filter has done its job.Thanks once again!

Hi mate , can you please share your thoughts on oil filters that mount vertically as Mazda OEM filters don’t have a drain back valve?

No special tools… pretty sure that’s a special specific tool.
