Well 6 months and 12000 miles later I just changed out the 4th roll of toilet paper on my Frantz bypass filter installed on my 2009 Ford F350 with the 6.4 Powerstroke. So far I've had no issues with the Frantz unit, maybe my only complaint is the rolls are pretty well spent after 3000 miles. I took this last roll to 3500 miles, but was taking just over 30-40 minutes for it to heat up and really wasn't getting very hot. Switch in a new roll and in 15 minutes of driving it's getting hot again and after an hour too hot to touch. This is a surprise for me as I installed it downstream of my Amsoil Dual-Gard with EABP100's on it to combat the Frantz from plugging up. I keep a spare canister ready to go, so a filter change only takes about 1-2 minutes now and I leave the used filter out to drain a couple of days then I dispose of it at the recycling depot. In the 12000 miles I've put in 4 quarts of oil for the Frantz and 2 quarts of top off for the burned oil and running Shell Rotella T 15W40. Next oil sample will be sent to the lab in 6 months. Here's some pictures and a video.:
