So I have a 2018 1.4 LS auto and I just replaced my engine air filter last week. I bought the wix filter from orileys and ever sense I installed it, my gas mileage has went from avg around 34-38 to about 28. I only commute to work and it’s all HWY driving. My driving habits have not changed and my tire pressure is normal. I live in SoCal so weather isn’t an issue. Any advice on how to combat this before I go to the dealer and attempt to have them try and diagnose this. Not throwing any codes either. Thanks in advance!
