Hi, did you people ever had issue with gas mileage ? I got 30 mpg right now with this engine. I've been driving the car a lot since I'm at 165k miles. A while before, I was getting 40, even 45 in the best days. I'm hyper milling the best way I can, cruise control with no ac and no window. Still getting 30 mpg. Something I noticed though, I did a compression test on the motor, since it has a lot of mileage, I got 173 psi on each piston. Mazda service manual states that I shouldn't get higher than like 120 since the timing is different. They said it can be a cause by an VVT error. Do anybody of you experience that ? What do you think !
