So how far have you folks that use the FRAM tough guards used it? I am on my 2nd oil change with a TG-3614 filter. No issues so far. I recall reading that member Stang5 I believe used one in a transmission for like 15 or 25k. Can't recall. Any info and advice is appreciated. The 2 MC-910S filters I have left will be donated to BlueOvalFilter since he is helping those less fortunate.
