Thanks to all that replied !
I am going to follow Tony’s advice and upgrade my “ Off engine filtration “.
Presently I only have a 30 micron primary off engine with the FF 5285 last chance filter.
Is my thinking correct to install a 30 micron and a 10 micron “ Off engine “ and then continue with the FF5285 “ On engine “ last chance filter ?
All help is much appreciated,
Rick
