    I have been told the M1-102 is the same filter as the M1-103 except for extra capacity. I would like to know if anyone has used it and if there are any clearance issues with the longer filter or any other problems.

    Your best bet is the M1-209 filter from Mobil 1. Just look at this post. Plenty of room and is much larger. M1-102 will not work.

    Yes the smaller one will work, but you wont have the cold start up protection(due to less oil capacity in the filter).

    Honestly, I dont see why people switch to K&N oil filters, or mobil 1 oil filters. The OEM ones work for that engine and are cheaper. I recommend OEM because they can be cheaper and were designed for that engine.

    I race both my cars and put them through more abuse that the average driver and I run synthetic oil and run OEM oil filters.

    Unfortunately I can't find details for the different Mobil 1 filters at Mobil's website. Using the detailed Wix website with cross-referenced Wix Filters, it appears that in addition to being longer and wider, the referred to Mobil 1 M1-102, M1-209, and K&N-2009 all use larger diameter gaskets than our OEM size filter. This makes me uneasy until I can confirm that the gasket isn't too close to the edge of mounting surface on the engine block.

    I like the Wix website for this because they provide more detailed specs on each filter and they produce more models, not aggregating different OEM filters into one approximate replacement filter as often as other filter makers. Here is the data from the Wix site.

    I concur. Price might be a consideration if buying OEM oil filters from a local dealership parts dept but with the wide availability of ordering OEM filters online for cheap renders this reason invalid. Additionally, OEM oil filters are added insurance should an internal engine failure occur under warranty.

    If a local dealership that you had to drive across town wants $6.50 for an OEM oil filter, where you could walk across the street and buy a K&N or Mobil 1 for two bucks more, I could understand going aftermarket. But when you can order a case of ten OEM oil filters online for $40 ($4/ea), OEM makes more sense.

    The K&N and Mobil 1 oil filters do seem like they're very well made, but there's not much justification for using them over OEM.

    The gasket for the Mobil1 M1-209 filter fully fits the mounting surface of the engine block. Justification of course is in the eye of the beholder. For my extra money the extra oil capacity, greater filter surface area, and finer multi-pass filtration of the Mobil1 filter tells me to use it. Do I need to-no. Do I want the best for the longevity of my Prius-yes.

    Just like the tires of our cars are not based only on the engineering of the suspension, the oil filters are a decision that is not based on filtration engineering alone. A given engine mounted in different cars will present different environments you have to negotiate to change the filter. On my Oldsmobile mini-van the filter spec'd is a small PF-47 only because a small percentage have an optional oil cooler which needs the smaller filter to have enough space to take it off. The engine in my mini-van does not have this oil cooler so I have choosen the PF-52 filter which is longer and wider and used in different vehicles with the same engine. Also remember that for a given group of engines although a given filter will provide better filtration the "bean counters" stay with one filter type for production and inventory purpose's as long as that filter type will perform the minimum to prevent a certain level of engine problems (warrenty claims).

    Thank you, Wayne, for the reassurance.

    I've often used slightly 'oversized' filters for the same reasons. To be fair, are there any other reasons to use smaller filters aside from using less resources, possibly faster warming of cold oil, and following manufacturer recommendations for troublefree warranty coverage?

    A couple of contrasting thoughts. On the G35 I used to drive, I did use a slightly oversize filter. The spec filter is the size of the M1-108, and goes by the nickname "the thimble filter". It really is that small. You could easily put two of them into a Coke can with room to spare. I used the "taller" M1-110 or the same-sized K&N HP-1010, which is about half again as tall. So yes, I have upsized myself. That said, I suspect that the M1-209, assuming it fits with a proper seal, is overkill on the little 1NZ-FXE. I use this filter on my wife's 4.7L Sequoia V-8, and per my oil analysis for that engine, it's not even close to loading up at the end of an OCI. In addition, my oil analysis consultant (Terry Dyson) assures me that the Toyota engines especially are clean runners that don't generate much crud at all in the first place. He and I have had this discussion a couple of times. His take is that an oversize isn't going do any harm (unless possibly you pick one with a bypass threshold that differs significantly from stock), but that the oversize won't do any added good, especially if you're staying remotely close to the prescribed OCIs. At least IMO, for this case, it pretty much boils down to personal preference, with one really being no better or worse than the other.

    I'll be doing UOAs on my next several fills of oil, and I order the particle counts too, which offer more info about filter performance. It will, of course, take some time, but I'll put 'em up when I get 'em. [​IMG]
