I am taking my CX-7 in next week for 12,000 check up . I will try to find out about the fuel situation. When gas was over $4.00 per gallon we didnot drive the CX-7 except for long trips. I would fill one tank premium, next tank 89 octane. I was making over 25mpg on the interstate, non mountain areas. went from deep SW Louisiana to extreme northern AR.
I also need to find out how many quarts of oil are needed with a oil filter and oil change. I cannot find it in the manual at all.
I am going to try the Pennzoil Platinum full systhetic 5W 30 this time.

You might get a better answer from Mazda USA than the dealer.
The manual that I downloaded says that you use 6 US quarts of oil when you do both an oil and filter change. 5.6 quarts just for an oil change.

Hmm, Venice to Bull Shoals eh? (oh, SW LA - haven't spent much time around Lake Charles, went south of there on my last road trip).

Does anyone know if the 2009 model Cx-7 is engineered to use regular fuel?

Yes, the new CX-7 engine can safely be fueled with regular, but maybe with no out-of-packet savings.
Should have been that way from the beginning.
