Right. Besides that, all the miles during which the engine was not running were miles in which the engine of a non-hybrid would've been loafing at very low or no load.

Looks awesome Michael. You the man !
Btw I wish I still had my 11 Prius it was totaled in 14 and the 14 I got as replacement I didn’t like as much for some reason. But good appliance cars.
I know your engine looks pristine, but any issues with burning oil? I believe these cars are notorious for burning oil because of the piston control rings.
They are. But knock on wood, no oil consumption on this one.
I think that is a testament to how well you've taken care of your engine with frequent OCI. I've got a 2009 Prius and it burns a little now (a little over a quart every OCI). I haven't been as good as you, as I've been doing longer OCI and I think that is coming back to haunt me. I've gone a few OCI at between 10k-12k miles. I stupidly thought that using Mobil 1 "extended performance" oil and Amsoil would allow me to run those longer OCI. Now, I can see some varnish at the oil fill opening too. From now on, I'll try to keep the OCI at 5k miles and below.
Looks good. Thanks for the pics.
In any hybrid, the gas engine runs as much as the car itself. Just at lower load and you can’t redline it. Even at WOT, I’ve seen 4500-5500RPM.
For a 2011 yes it is at least 97% of the miles. They only really use the traction battery at a stop or starting. So the engine has maybe a tic under 220k depending on conditions.
Looks great
My experience is that japanese cars useally have very simple cranckcase ventilation systems which work like they should for 20 years. Also my mates K20a2 honda engine looks like new inside after 20 years. That system consists of 1 8cm rubber hose between valve cover and intake.
My bmw has electricaly heated pipes, vacuum controlled air/oil separator. On the drawing board it maybe looks nice but useally after 5/7 years its broken/cracked/clogged etc... without giving symptoms and the engine sludges/carbonizes up.
From what i can see cars with metal/alluminium headcovers are useally less prone to sludge etc.. then plastic cover ones. Presumably because the alluminum/metal heatsoaks quicker from the cylinder head and so evaporates the water sludge.

Not so, except in circumstances like using the car mostly for long trips at steady speeds on gentle terrain. That's almost as far off as the poster who claimed the engine runs a small percentage of the time. Realistic might be 60-90% when there are hills and stops, etc.
I average 38-40 mpg with 17" tires, so it gets driven pretty hard. Especially by my wife. I am pretty sure the engine is on more than 60% of the time.
I have owned 5 Prius (2007, 2012, 2008, 2015, 2015) and the ONLY ones I had oil burning issues on was my 2007's. I have owned 3 third generation prius, and they never consume any oil.
It's not a plug in, he doesn't granny it off the line so realistically it's only off when there is no high electrical load, he is stopped or on an extended downhill. That's not 40% maybe more realistic is 10-15. The engine is what primarily moves the car not electric motor (s).
