Any real limit to running REX?

In reality, whether BEV or REx suits you better depends on your circumstances and, to an extent, your location. I've owned my 120Ah BEV for more than 18 months now, and I've never had a situation where I would have needed to use the REx engine - so for my circumstances it would simply be a waste - weight carried around everywhere without any useful purpose.

Exactly our situation. For over a decade, we have used our i3's for what BMW designed them, to be a megacity vehicle. We've never road-tripped them, so a REx would have been a waste. I am very happy to be done with ICE maintenance and problems.

You can go to a small airport and buy 100ll (low lead) they don't allow corn lcker in aviation fuel yet. Good stuff for small engines that sit a lot like lawnmowers in the great white North

Are you sure the Rex does not have a catalyser? I use 100LL on everything i can that does not have a catalyser. Like my generator, old cars, even mixed in chainsaw, but i never tried in the Rex because i was thinking it have a catalyser. I would surely use 100LL if it does not have a catalyser

The REx engine does have a catalytic converter. "An air-gap-insulated exhaust manifold enables the catalytic converter near the engine to heat up quickly through minimal heat losses."
