Switching to a 5W30 may reduce oil consumption, from my experience it doesn't burn nearly as easily as 0W20 in a slightly tired engine.

Gotcha.

Just Super tech Full Synthetic.

I use that in all of my vehicles with good results. Price is great too.

If I remember correctly, swapping to a 40W in the old civic reduced oil consumption by about 20%. Have you had good results with yours?

I don't have a Prius, but I do have experience with worn out engines. When my 05 Civic's engine started to fail and burn oil it was eventually using about a quart of 5W20 every 600 miles, but I was able to go nearly 1000 miles on a quart of 5W30 and it ran noticeably quieter and smoother too. I don't know how much it would have used with 0W20, but past experience tells me that it would have been worse than 5W20. Switching to 5W40 reduced consumption even further to about 1 quart every 1200 miles. Now that it has a healthy engine I use 5W30 and it burns about 1/2 quart between oil changes (4000 miles), which I am not at all worried about.

I'd suggest looking into a "High-Milage" oil, to see if the additives help any. It's kept a number of my cars/engines happy over the years.

That includes one that previously kept wearing out or contaminating the oil(fuel perhaps?) so that it got thinner and wound up burning it at a similar rate as yours. It would always come out thin and black at oil changes; that stopped right away with HM oil. Engines also run quieter on it.

YMMV. And you'll want to do your own research to make sure the added metal(s) - zink was it? - aren't "known" to damage your particular emissions equipment. Which means sifting through a lot of opinions and deciding for yourself if it is worth trying or not.

HM oil probably has similar stuff in it as the engine restore you tried. I used one of those to keep an aged engine happy - smooth and quiet (valve train noise mainly) - but would have to put another one in ever 1000 miles or so. The "need" to used it went away with HM oil.

Besides that...since that could all be in my imagination, and some people won't touch that snake oil, has anyone on the Prius forums had any success soaking their cylinders down with ATF? The idea being it will clean carbon off and free up stuck piston rings. It was one of the band-aids the techs I worked with used to breathe some life in to abused or aged engines.

For the most part I've seen zero success besides using a catch can on the Prius Forums. Toyota used low friction piston rings on the 4 cylinder engines from like 08-12 on the models introduced in that time and they were oil burners after about 50k miles. I just wanted to try comp restore as I've seen it help a lot on Chevys with their LQ/LS blow by issues and not a single person mentioned trying it on the Prius forums. 2012+ they fixed the issue but they pretty much ignore you unless you're engine is burning a quart like every 100 miles or whatever the max spec is. Car runs just fine with no loss of power but the pcv squirts oil like a fresh well in Texas.
By american standards burning a quart every 3k is about in line with all american vehicles up to about 2005. lol

Going to attempt to carry this oil change out to 6-7k, then drain the oil and start throwing on the new fancy oil catch can that returns the oil blow by to the sump. Just kinda waiting on moving into the new house so I have a garage to do it in with plenty of space.
