Would this stuff work well for our rotary engines?

"AMSOIL Antifreeze & Engine Coolant provides extended service life in all gasoline and diesel vehicles. It can be used for seven years or 250,000 miles in passenger cars, light-duty trucks, vans and recreational vehicles. It lasts seven years or 750,000 miles in over-the-road diesel trucks. Also good for motorcycles, ATVs, snowmobiles and closed marine applications. AMSOIL Antifreeze & Engine Coolant lasts longer than conventional products."

I've read somewhere that due to the high heat the rotary engine generates you should replace the coolant every 1-2 years.

I'd like to replace all of the fluids in my RX8 soon since I bought it used and just want to go under the assumption that the previous owner didn't replace the coolant. (4 years, 22k miles).

 

Yes you can use this in any Rotary engine. Its a great product.
I've been using Amsoil products in my cars for over 20 years.
