Still trying to sort out the low fuel economy issue and not making any progress.
So I decided to tackle an easy issue. New headlights.
I've tried cleaning them and even when I put a lot of effort into it, they still looked crappy. $70 later, new lenses arrived at my door. I should have done this years ago. Almost literally the difference between night and day.
Old vs New lenses
All back together.
I'm probably at three times the light output I had yesterday, and even when I cleaned my old lenses, I wasn't anywhere close to the same light output.
