Not everyone has just "a little carbon" genius. And the less of it, the better especially in these new GDI engines where bottled additives ("Mystery" bs included) can't reach the back of the valves. I have video evidence Seafoam and BG remove carbon...where's yours? Oh wait...carbon is "good" my bad....thats why your mpg and compression drops the more carbon there is. Posted via the PriusChat mobile app. I use Top Tier all the time. I also found a BP with E0 I started using yesterday. Going to go thru 10 tanks and compare on Fuelly which shouldn't take long driving Uber/Lyft. You shouldn't have to use premium. I still suggest taking it for a fuel induction service (BG or other brand) and if after a time that doesn't work, have a good mechanic remove each injector and soak/inspect them. There's ways they can test them out of the car too. That way if one or more aren't performing correctly, you can have it replaced while they ate out.

And there is no possible way that this "evidence" has been created in such a way as to appeal to gullible people like YOU.......when there is nothing there that needs to be "treated" in the first place ????? Hint: It is marketing hype and YOU are living proof that it works; the hype that is, not the product. But rant on if it makes you feel better. And by all means, continue to waste your money if it makes you feel good. My rebuttals are posted for others, not for you.
Lololololol Posted via the PriusChat mobile app. Prove it. I did Posted via the PriusChat mobile app.
OK, now it is YOUR turn........genius. Please tell us exactly how an injector can cause pre-ignition pinging ??? Hint: It won't. I quit. This is pointless.
Bye Posted via the PriusChat mobile app. (FYI injectors spray before ignition...before= pre-ignition.) Posted via the PriusChat mobile app.
Fractured logic. The injectors have NOTHING to do with pre-ignition detonation. Just give up; you are just digging the hole deeper.
No problem. Anyway, Bgustafson I would try what I said above. If you do the induction service let us know if that helped. It's helped a few times for me. One thing I did notice is I used to have a GMC Acadia and with E10, I could always hear an injector ticking. When I switched to E0 it went away and it ran and idled much smoother. But where I lived then E0 was only 10-15 cents/gal more. Where I am now, its 99 cents more. That being said I'm trying 10 tanks of E0 and tracking on Fuelly. If the per mile is lower or close to the same as the E10 (currently 5.2 cents per mile) I'll stick with E0. Posted via the PriusChat mobile app.
I think I will be looking at the spark plugs first. Most likely it sounds like they need replacing. If so, I will do that and then see if the issue resolves. As I mentioned before, I'm running premium without any pinging, so at least that is a temporary solution to avoid further engine damage.
I'm willing to bet that was the issue. What brand plugs and how many miles on the car? Posted via the PriusChat mobile app.
I'll check the brand when I pull them. It has 176k. From what I've read, people like the Denso plugs? I'm looking at some sk401 iseium power 4 plugs.
I'm sticking with what Toyota puts in them. But I have a ways to go. The reason I ask is if the plug brand is the same as factory, its highly possible those are original. Not sure of your model but mine says replace at 125,000 miles (instead of 100k like my non hybrid cars). I would suspect all 4 will look like that. Prepare to see your gas mileage go up and driving better. Those look really bad Posted via the PriusChat mobile app.
May I politely suggest that after asking for help you follow it up sooner in future for your own good. Now unless you understand all spark plugs are not interchangeable, I'd advise using the Toyota recommended plugs because they were sure to fire the right temperature range for the engine. You cannot greatly improve the hybrid performance of a Prius by using high performance plugs.
There is no such thing as a "power" spark plug. And it is foolish to pay more for replacement plugs than what stock ones would cost. It looks to me like those are WAY past their useful life and the electrodes are eroded away. BUT there isn't any real sign of grossly excessive carbon buildup. New plugs first and then drop back to regular gas and see what happens.
