I use the M1c-451 on my '11 Jetta 2.5. Due to a fair amount of short trips, I change the oil at 5-7.5k. It's a cartridge filter, so I get a good look when I pull it. At a recent change of 6k, the filter looked really great. Thoughts on reusing the filter for another OCI? I changed it this time, but I am thinking of reusing it in the future.
Any input is appreciated.
