So far, I have used fram on two complete oil changes, one went to 7200 miles before I replaced it. From what I could see and hear, about 7,200 miles was as far as it seem to go before I started to hear upper noise on startup, So IMO, fram should have no problem serving you 5,000 miles.
Like toyota's, my filter is also a side mount and does have an antidrain back valve, and I've not experienced any trouble so far. I have removed all filters, cut them open and examined, so far, no deterioration on those "cardboard" endcaps, and filter seems to be in good order.
After this last test I run with the 5w30 mineral oil, I will be trying the bosch filter, but hopefully before then, we'll have the filter jig setup and beable to see how flow is between these types of filters and from this, I'll be making my next choice as to what I'm going to use. If fram has the best flow, I'll end up with that, but I really don't think they will be the best, but they sure are not the worst IMO. I will agree, that fram has had some bad publicity with the anti drain back issues, but so far, I've been fine from the experiences that I have seen so far.
