I just filled up and calculated my mileage. 24.2. I was getting consistently 19 to 20 combined for a long time.
To my story - I had a vacuum hose come loose (think that's what it's called). I was seeing a slow but steady downslide in mileage. Finally, it came right off and caused all sorts of difficult to diagnose problems.
Anyway, now that it's back on, I get consistently 24 mpg combined. Not only that, I'm leaving early and driving the speed limit (70 where I live). That might have something to do with it.
But it's my guess that the loose hose was causing the biggest loss of mileage.
The luggage rack comes off this weekend. I have had the vehicle for 2 years and never used that blasted thing.
I'm glad I was tracking my gas mileage for the first 2 years I owned the vehicle. It's going to make it easier to track once I start making mods.
Another example of proper maintainence - good find ! I know as fact that some elusive issues can be fixed by a simple replacement of vac lines . Most people don't realize they are not a life of the car part should be inspected / replaced as needed every oil change.
