I am considering getting one of the Fumoto valves to make it easier to collect a periodic oil sample (I have one of the hand pumps but it doesn't seem to work that well with my particular dipstick tub...
Here's a question for all of you that use the Fumoto. My Cummins has a pretty strong magnet in the original oil plug, and the Fumoto has none. While my engine never has any debris on the magnet, I wonder if it's not a good idea to have it in use in case something starts to go awry.
I've used the Fumoto for a number of years, but am not altogether comfortable with not having a magnet in the system. I wish Fumoto had a valve with the magnet installed..!
