Accidentally filled with Dex-Cool o no !
Flushed and refilled with dex-cool...had a full container in the garage and decided to use it, didn't realize it until now that its not a good choice for the rotary!
Its been in the car for 30 days..cars only been driven on weekends. Is there any damage that could have occured in this time period? I'm going to flush the car with prestone flush and distilled water then refill with prestone coolant!

Dexcool CANNOT be mixed with regular coolant. Drain it immediately and throughly flush the system with water. Then refill with the proper mixture of green coolant and distilled water. While you can theoretically use Dexcool, I wouldn't because the seals in these motors were not designed for it. Its know to attack certain materials and there is some evidence that points at it eating the coolant o-rings. I would just use the green stuff. The only benefit of Dexcool is claimed longer service life. You should be changing your coolant every season anyway.

While I'm not advocating the use of Dexcool, many rotary owners have used it very successfully without issues (i.e. with the proper draining/flushing first). I believe Chuck (cewrx7r1) still uses it and you can find several of his posts in the past on the subject. I will say that I would not use it, but there are a lot of thing with these cars that I would not do but other people have no problems doing.

Yeah, my dad's Park Avenue blew its head gaskets and when the engine was torn down it was just ATE UP...machined surfaces looked worse than cast...gnarly, dude.
All from Dex-Cool....what a failed experiment THAT was for GM.

All that stuff about DEX-Cool being bad for rotaries is pure BULL ****!
There is no direct verifiable evidence of it. The early problems that some GM vehicles had with it was due to other maintenance problems.
I have been running it since 1999 without any problems when I rebuilt my engine. It has been producing over 347 whp since then on the twins and more power since 2005 with a GT35R. But I do use distilled water and never any tap water.
