weird... better gas mileage??
So, I decided to test out why exactly we need 93 octane... so I have been filling with regular lately. After 3 tanks of 89 octane, the car is running just as it was before, if not better. I am also getting better gas mileage. I used to get 18-20mpg with a mix of city and some highway driving. Now without changing my driving style and driving the same places, I am getting 23-25mpg... doesn't make any sense to me but I am paying $1.90 instead of $2.20+ so oh well. BTW stock ECU
