Those are all what I'd consider on the end of the "high efficiency" scale, and of course there will not be enough difference between those efficiencies to see a "wear difference" in UOAs. However, you may see a slight PC difference between them.
Now Zee, if you're going to start off the new year injecting common sense and logic into threads, I'm not sure where to go from here ....
But seriously, I do think the difference between those three models (EG, TG, U) is pretty much indistinguishable in 5k miles, or honestly even 10k miles. They all will have the capacity and efficiency needed and we'd not ever be able to tell them apart in terms of wear control. I was using the TGs fairly regularly, but now that they've up'd the EG to 10k miles it may well be my new go-to filter. I'd take it over a MC right now; that's for sure.
So, for a 5k mile OFCI, why spend $12 (Ultra) when $4 (EG) gets you the same result???????????
You're surly not getting 3x less wear, nor 3x longer use (because of the self-imposed OFCI limit) by using the Ultra over the EG.
This is why I cannot understand how others cannot understand the topic.
Too many people want to set a $ limit, and then try to pick a filter.
Rather, one should define the criteria desired for the OFCI, and then select the least cost filter that will maintain that safe margin of operation.
If Fram says the EG is good for 10k miles, then I suspect it's safety margin is well past that!
