All factors are equal. Didn't change habits. Still cruzing around 70-75mph on the hwy. same Costco premium. Air temp between 55-60 degrees.The ECU wont "freak out" due to a simple filter change. When you put in the filter, what were you're driving habits like? Have you hooned around town with it in? Did it get super cold? Did you change up fuel.
Are you going by the computer MPG estimate numbers? If so how many miles since you reset the MPG average.
34-26 is a pretty drastic change so those numbers do not look accurate to me. I would run a tank thru the car and do a manual calculation at next fill up. Compare that number to your normal MPG average. Pretty sure it will be in line with what you normally get or only off by 1-2.
Will do. I'll clear through this tank and see how it goes from thereYou're car is still pretty new. Do a fill fresh fill up from E and see what happens.
When I added my filter, my MPG went up 1-3 pts.
Did you notice better mpg with full synthetic? This is my daily and I'm trying to get the best possible lolOil, fuel quality, tires and road conditions are all factory id milage. When I was getting mid 30s I set my cruise at 65 and had a set of Kumho 4X all seasons in 235/40/18. Also changed to Mobil 1 Full Synthetic. Now I get low 30s due to mods and summer tires.
