I'd like to respond to everyone at once, and also preface with the fact that since this is really my first post on this forum, I don't want to come off like I'm peddling someone's product (I may do a write up at some point but for the time being I'm not naming names).
1. Donald: I currently use a spin on filter - Donaldson P564967, in a parallel flow configuration that seems to work quite well.
2. Ihatetochangeoil: My idea definitely does not follow typical logic in that I'm not necessarily after extended UOA's or to save any money for that matter. I would just like to keep my vehicle in good running condition as long as possible. As far as guessing how long the element will last, the quick answer is differential pressure as determined by pressure gauges on a housing. (I DO NOT INTEND TO COME OFF SARCASTIC OR NEGATIVE IN ANY WAY)
3. Crusher: I have an existing system on an 06 Tacoma 1GR-FE. It is not a standard bypass setup whereby the return goes back to the sump via different routes. I initially tried this with a Frantz and plumbed a "Tee" off the oil sending unit, however the VVTI on this engine was not actuating properly, apparently due to that minor drop in oil pressure from tapping that location (I tried a flow restrictor as well as changing to the smallest hose I could get my hands on. I could not get it working properly and ended up trying a parallel system as I was on a trip and able to pick it up. It has worked very well based only on my own "seat of the pants" assessment. I do not have UOA's to back it up at this time, however, time permitting, this may change in the near future.
4. xtell: 2006 Toyota Tacoma, engine 1GR-FE, oil brand has changed a few times, although I had run 5W30 QSUD for about 4 months and the truck ran great. Before that, RP because I got it cheap-ish and I thought it was great. Currently I've got about 3/4 sump of 0w20 MAG 1 and some leftoever 5W30 QSUD (weather was cold enough that it was starting rough so I did it in a pinch, seems ok though). As far as budget, I'm just curious to see if I can make this work BETTER (IMHO) and for what money. If it seems feasible I will attempt it, if not, I'll run what brung me. And to your final question, it is a parallel system, as this was the only way I could get very fine filtration while still allowing the VVTI to properly actuate. Obviously this isn't a new vehicle, its just about at 100k, but I've always taken great care of it, doing scheduled myself on time.
Again, I'm not saying I'm trying to re-invent the wheel, just perhaps DIY improve upon something I've already got because.....well because I guess I want to. I apologize if this does not jive well with the notion that these systems should only be used for extended UOA's to see a reasonable ROI. The fact of the matter is that I don't put enough miles on the ODO each year for that to be super beneficial. On the contrary, my commute is short, this system seemed to greatly improve how well my truck runs on a day to day basis. The other DIY addon I've got is a home made PCV separator and that seems to make a noticeable improvement as well. I've got questions on suggestions for that as well, probably in another post however.
Thank you all for your time, input and replies. I am taking your advice into consideration, and am excited to see what your future response to this will be. Have a great evening.
