I think I'm going to do the same with the Tough Guard. I'm just not a little bit leery of having a Tough guard go one full year?Went to the local walmart they had (3) of the older style wire mesh left in my application (3387a), unfortunately all three had been opened and two had ripped cardboard boxes. I might try the tough guard for two 5,000 oil changes, seems like a good value at that rate.
