I have a Mazda CX7 which has a turbo charged 4 cylinder engine. When I got it, the EPA millage was supposed to be 27 miles per gallon so I thought it would be a good gas savings from my 4Runner which got about 18 miles per gallon. I knew that the manufacturer said that I had to use Super Unleaded gas with the turbo charger, but I figured the 9 miles per gallon difference would more than make up for that. Unfortunately, the CX7 really only gets about 20 miles per gallon. I like the car and it handles really well with the Turbo Charger and sport tuned suspension, but Super Unleaded gas at 20 miles per gallon is not much fun.
Anyway, does anyone here know if I really need to use Super Unleaded with a turbo charger? If not, can I use regular? If I use regular would their be any long term consequences? FWIW, I've put regular and plus in it once in awhile, when I was forced to use a station with really expensive gas, and did not notice any performance difference.
