I'm not sure if sludge would accumulate in a filter or not, so I thought I'd ask.
Background--i recently inherited the camry in my sig, no problems with engine, I drove it 30 miles home, no overheating or leaks, no gunk on dipstick. However, there is no maintenance record, so I don't know the OCI.
Now that I just found out that this engine is on the sludge monster list (2.2L 4 cyl), I have decided to run 5K OCIs, no more than that. In the past when Ive run OCIs that short, I liked to use a Wix for two OCIs. I am concerned about clogging it up if I take the filter to 10K, especially since this is such a small one (IIRC it is just about three inches tall, outer dimension).
So I'm wondering if having the current filter cut open, or one that I put on (so I know for how many miles its been on) would be helpful? Or could it have sludge problems but still not show up in the filter, so this would be a waste of time & money to ship it to someone? Or should I just try to oversize the filter and forget about chasing the holy grail (detecting sludge on a car that has shown no evidence of any)?
