TalonTsi90. I drove an '18 for 1000ish miles and only put 87 in it since it was a loaner and it was pretty powerful. Now, ive been running 93 in my 3 for about a year now and after 3 full tanks, something lit up and the car started responding a lot more than it did. I thought it might be a fluke, but one tank of 87 reduced that gain and on the The SkyActiv-X is also supercharged, although the function of this supercharger is to ram as much air possible to maintain a very lean air-fuel ratio (more air, less fuel). The lean air-fuel ratio helps to prevent knocking in the high compression design engine. So there you have it, that is what’s special about the Mazda SkyActiv gasolin engines.
