    I've done a ton of reading on the subject around these forums and the web, and I think there are enough positive results to at least give it a try if you're burning oil. Seems like some folks don't have any change in their consumption but there are a lot of variables which could effect the outcome. Namely, how much carbon build up they may have had or how worn their rings may have already been. I think if the rings are caked then repeated flushes might bring better results, but if the rings were already worn than there's probably nothing one could do aside from replace them.

    I've just started using the BG products myself and plan on monitoring my oil consumption very closely going forward to see if there's any change. Fingers crossed.

    For reference, earlier this year I cleaned my EGR circuit then had my dealership do the fuel injector and de-carb service which I then followed up with running a can of BG 44K for a tank and a half. This made my car feel smoother and did increase my MPG but rapidly accelerated my oil burning so I figure there was a ton of blow by happening. Considering how quickly the oil was darkening though, I think it was removing a ton of build up from the combustion chamber and maybe around the rings and pistons. At this point my car is burning roughly a quart every 1200 miles. My original plan was to run all three products at my next oil change but rather than risk another rapid burning situation, I only did the EPR flush w/ MOA afterwards in the clean oil. What I'm thinking now is that I'll run BG 44K again just before my next oil change and then do EPR and MOA again, which should clean things up pretty nice. And I'll have more data about my oil consumption then too.

    I proactively use all 3 products as well. 125k zero oil consumption.

    Curious what interval you follow for these. Thanks.

    I do 44K once a year, MOA and EPR at every 5K oil change.

    Curious if you are seeing improvement in oil consumption with each of these 5K oil changes. How often do you plan to use EPR/MOA once the consumption is fixed/stabilized.

    I went from burning around a quart every 2500 miles to roughly a quart every 5000 miles. So far I've only noticed my car burning more oil if I'm doing a lot of uphill driving. I plan to keep using them at every oil change.

    Has it stabilized at a quart every 2500 miles or are you still seeing improvement with each oil change?

    I first started using the products over a year ago and it took only one time to make a difference. I have burned roughly one quart every 5000 miles **since then, at every oil change**. Pre-BG - 1qt every 2500 miles. Post-BG - 1qt every 5000 miles.

    I suggest letting the EPR work for at least twenty minutes when you use it, not the ten minutes the label says.

    Did you notice any difference in the color of the drained oil after having used EPR compared with the color of the oil that you had been draining previously? -- assuming that it was the same brand, weight, etc. of oil. As I reported in another thread, when I used EPR in a Pontiac Vibe with 166K miles, the drained oil looked like melted chocolate, very different from the oil I had drained previously -- but I have no way of knowing whether that was because the EPR was loosening/dissolving sludge, varnish, or whatever, or whether EPR contains a compound that turns brown when it is heated or mixed with oil.

    My Prius is due for an oil change again soon (based on time, rather than on mileage), and it has a Fumoto drain valve, so I am inclined to drain a little oil before adding EPR, and compare with the oil drained after the EPR treatment.

    When I would do the EPR treatment on I old 2010, there was a noticeable difference in color between the two ;).

    We have 26k miles on our 2019 Prime and now out of the factory maintenance program, I'll be doing the BG Products route at 30 k miles for the next oil change:).

    With the Prime we are at about 70% EV, so the miles the engine runs are low, but that should be good for long term engine health if I keep feeding it high quality synthetic oil and MOA, the engine should be good for a long time(y).

    Personally didn't notice much of a color change, even though the engine was warm and it had idled for some time. Guess it could've had something to do with my lower change interval, but did expect more considering the prior second hand experience I had with the product.

    The one time I did see a dramatic difference in color was when @Raytheeagle did a treatment, and it was quite dark in color. Not sure why that was, maybe the higher change interval or something oxidizing between the old oil/remaining BG additives and the EPR.
    Given my limited experience, I would doubt if there are additives (in EPR at least) that change color, but it also wouldn't surprise me either.

    Had similar results to EPR when using B12 chemtool a few times, now looking to try Kreen as an oil treatment and as a piston soak.

    At one of the meetups we did an oil change for comparison, and I believe @Rebound 's PIP was the other Prius we compared against;).

    Definitely a difference between the two(y).

    Have you been using the ones marked as being "for hybrids" (different color package but the same part#)?

    No, I've just been using the same older cans. I'm pretty sure it's the exact same product just w/ a different label, for marketing purposes.

    That's what I assumed.

    And are you using the original MOA (PN110) or the new and improved PN115? The MSDS docs show very different ingredients.

    I've used them both. It wasn't on purpose, I just bought what was cheaper when I was looking. I think the 115 "Advanced" does some extra things for GDI engines. For an average Prius, I doubt there would be any meaningful difference. But I'm not a mechanic or engineer. Maybe someone with more knowledge could compare the two and inform us if one is better than the other for Prius cars.
