I used to get about 19 mpg in the Jeep. Since bumping it down to weekend duty (I was putting 300-500 miles a week on it) my mileage has tanked. It got down to 13 mpg for a minute there.
Somebody stole my gas cap while it was sitting, and after a new cap and running some seafoam through it I'm up to 15 or 16. I think the weight of my feet may have changed a little with my new truck so that may account for some of it. I'm hoping that running it around the block a few times every day may help out a little too.
No real question here, I just needed to rant to some understanding ears.
Any ideas would be greatly appreciated though.
