Engine coolant - OK to switch brands?

Hi:
I need to change the coolant in my 09 aveo. The dexcool 50/50 is very expensive in Egypt. There is mobil extra coolant ready mixed 33%. Is there a problem if I used it?
Thanks

everything on the net says do a complete flush before switching

Thanks. I will do, but this coolant is 33.3% and the recommended is 50% but the recommended is expensive more than 1000 L.E. and this 33.3% is by 300 L.E.
So, Is there a problem in using 33.3% instead of 50%?
Thanks

you should be fine, it doesnt get super super cold there unlike some of the northern states of the us.
