But, just about any engine will turn with enough force.

Use to work for Enterprise. They changed oil around 4-6K intervals. I've seen some go as long as 12K where I worked. Oil is the "life blood" of the engine. I change mine every 3K no matter what anyone says. I got over 250K mi on my last car and it was still kicking. I would NEVER buy a used car from a rental company or stealership. Sometimes used cars will state it had one previous owner. That owner could have been a rental company so it can be misleading if you don't dig in the weeds.

We bought a Budget Altima that had extremely low mileage because it spent most of it's life waiting for body work. Turned out to be a good, but boring car. Bulletproof. Handed it down to the kid and he drove it for a couple years before totaling it going to work.
Worked for us; especially for the price.

wow, just wow.
IS this guy for realz? Telling me to look up some info about this engine?
WOW.
wow, u took a smart pill today ?
I like his last line,
"impossible for the motor to seize. even in extreme over heating situations."
hmm ok
No need, I just took an unusually smart lesson today. taught by you of course.
Rofl.
dude, seriously, you have NO IDEA WHAT THE #$*% YOU ARE TALKING ABOUT. Please stop. Just just stop. sheesh. Before you have a single damn clue about this engine, please just stop posting. damn.

Cuz I know how those people drove those rentals ... I was one of them, I beat the **** out of it whenever possible ...

:fyi:
The part abotu not having to change the oil was posted as a joke... The other part, about not being able to seize the engine is fact. Was referenced from some knowledgable people on this forum, and then confirmed through some research... If you still dont believe it coming from me, I suggest you do the searching for yourselves...

Sad when for only a couple hundred bucks that Saturn could probably be running just fine. That can't be good for Enterprise financial.
FYI Cars (not even Saturns) are intended to be disposable. Try to take care of it.

The theoretical mechanics of thermal expansion between dissimilar metals does not account for things like bearings, friction, warping, or any number of real world conditions.
By your logic, an aluminum V8 block with cast iron pistons would be impossible to seize as well.
Is a Renesis prone to heat welding its rotors to the rotor housing? No, and it is in part for the reasons you describe. It can still fail catastrophically in some other way that would be appropriately described as "seized" (A bearing failure comes immediately to mind.) Such failures can easily be brought about by oil starvation or sludge.
I believe you though, when you say you had your tongue in your cheek when you said you never need to change the oil on an 8, just keep topping it up.
You made a mistake, you got called on it. Accept that today you play the role of the fool, as we all do from time to time, and gracefully exit stage right.

You sound like and engineering student who just learned about thermo-coefficients of expansion. And if you just look at the expansion coefficients of both aluminum and iron, then yes, aluminum expands more per degree. But thats all that says.
You don't think that any of the inherent stresses of the dissimilar metals (front and rear irons, aluminum housings, bearing materials, etc) would cause something to change shape and bind up?
BTW...there are video's or rotary engines seizing..and I guess that depends on your definition of seizing. If a bearing seizes, then yes, I would call that a seized engine (it is in a condition that will not allow it to run under its own power). Could you still turn it with enough force...yes. But, just about any engine will turn with enough force.
Anything with bearings has the potential to seize.
