    With the right oils, the oil burn is very slow. I'll give the thread a recap though for those who got distracted:

    Here's what I've learned so far: Adriatic Spindle Oil (a specific type of oil additive with CAS 64742-65-0) is an ingredient in the OEM Toyota Oil used at 1-5% and is used in heat transfer applications up to at least 600F as well as being used for a motor treatment/engine cleanser. It's purpose is likely to reduce heat at the point of contact where some part or another gets hot enough to burn other paraffinic oils in absence of CAS 64742-65-0 with low flash point temperatures and keep them from accumulating where some oils intentionally leave waxy deposits to prevent engine wear in engines were design tolerances aren't as close. It's the absence of Adriatic Spindle Oil (and there are many spindle oils, all with different chemical properties) and the accumulation of burnt low flash point paraffinic oils that leads to oil burn in the first place per the hypothesis that I'm currently using. I won't know if I actually do need to replace the engine or if it was just maintained with non Toyota oil and can just be cleaned up and put back on Toyota's recommended oil with the additives necessary to reduce or eliminate oil burn and maximize engine life(people in lower income countries will put a new paint job and a couple hundred thousand miles on these econo luxury cars when we're done with them). Anyways, the initial oil burn would seem to be higher in cleaner engines.

    I've also stated that Edge/Magnatec tends to burn more oil and is designed to burn given the low flash point ingredients and Toyota notes that their cars can be expected to burn oil (that checking and adding oil is normal maintenance), this is likely b/c they know that non Toyota oils lacking ASO will generate more friction in some part of the engine and burn lower flashpoint oils which the engine isn't designed for. If I was topping up with Pennzoil, the oil burn would be pretty negligible, and once I clean all of the burnt low flash point paraffinic oil residues out of the engine and switch to Toyota oil or Pennzoil with the necessary ingredients, I hypothesize that this engine will stop burning oil and that I will have helped many owners solve their oil burning eco car dilemmas and get back to having a nice convenient, reliable, and efficient car. At present, my hypothesis is that Prius owners are under informed as to the importance of oil ingredients and could be spending money on engine repairs and oil top ups that could be better spent on other areas of vehicle maintenance.

    Spindle oil is mentioned in the Repair Manual, as an O-ring lubricant when installing the fuel injectors. They say to use either spindle oil or gasoline. I looked it up too, seems like pretty obscure stuff, often sold in 5 gallon pails.

    Instead of using obscure ingredients to make a “snake oil” that your car won’t burn, just use the Pennzoil you mentioned that doesn’t burn off. “Negligible” is the word that you used.

    There are lots of Spindle Oils, only this one afaik is useful for heat transfer which can reduce burning by taking heat from other oil molecules. If I can get the engine clean enough to either switch it back to Toyota oil or add CAS 64742-65-0 (Adriatic Spindle Oil... not it's only name, but the most memorable of them) to the Pennzoil to reduce or eliminate oil burn and thus reduce or eliminate the risk of failure due to oil burn, that would be ideal, especially for resale value. Not to mention the higher temperature internal components will likely last longer. Duralube could be the answer if used in 6oz quantities.

    At one point, with Seafoam in the oil, I had 10k used oil (castrol magnatec of all things) not burning a drop! Which would be nice and convenient for added peace of mind, but it had to be changed. Ideally, I won't have to add much oil to the engine, and it'll be pretty clean when I do the valve adjustment in a few thousand miles, meaning my tools will also take less time to clean. A tidy engine is a tidy toolset! It also occurs to me that if that works, I might be able to save a few more dollars using supertech synthetic with Adriatic Spindle Oil which would still be ~$4 less than Pennzoil.

    As far as obscurity goes... if you find a common use for it and post on a forum or youtube, someone will usually start selling it. When they don't, it involves someone's still in force patent. That's the power of public forums!

    The "power" of public forums is two fold:

    Good information is disseminated at the speed of light.

    BAD information is also disseminated at the speed of light.

    Often the BAD information is presented so skillfully that it looks good.
    Self-proclaimed experts usually are NOT.

    FYI
    To OP and others about filter size . I did a search on ROCKAUTO .

    All of these models share the same oil filter size
    YARIS 05-09
    PRIUS Gen2 04-09
    Matrix /Vibe out of production
    Echo
    Prius C
    Both FRAM and BOSCH same

    Is this thread about a mechanical physical size oil filter or oil refinement /oil type

    Honda is similar: every one I've encountered uses the same filter. Used to be their motorcycle filter, fwiw. At least it was dimensionally identical.

    It started as an oil filter size topic, but it's branched out to explain my oil experiments.
