I use the original type filter on the TF, Tecalmit, never went to the spin on, no need! Changing the cartridge is a no brainer. I remove the fill plug on the pump and pressure fill the filter container. It's also easy. I use Wix filters. My car gets an oil change once a year, just before putting it to bed for the winter. The car doesn't get driven much, so the oil isn't even dirty, but change it to get rid of any contaminants. I know the earlier TDs have a different setup and if you don't need originality, any way to make it easier is the way to go. PJ
